 All right, welcome to today's CNCF Live webinar. Thank you for joining us, Enhancing Data Protection Workflows with Canister and Argo Workflows. I'm Libby Schultz and I'll be moderating today's webinar. I'm gonna read our code of conduct and then hand over to Ivan Sims, software engineer and Michael Cade, senior global technologist, both with cast in by Veeam. A few housekeeping items before we get started. During the webinar, you are not able to talk as an attendee, but you can give us messages and send questions through the chat box on the right-hand side of the screen. Please feel free to drop your questions there. We'll get to as many as we can at the end or as the speakers see fit as we go. This is an official webinar of the CNCF and is such a subject to the CNCF code of conduct. Please do not add anything to the chat or questions that would be in violation of that code of conduct. Basically, please be respectful of all of your fellow participants and presenters. Please also note that the recording and slides will be posted later today to the CNCF online programs page at community.cncf.io under online programs. They're also available via your registration link and the recording will also be made available on our online programs YouTube playlist. With that, I will hand things over to Ivan and Michael to kick it off. Thanks, thanks, Lipee. Let me share my screen here. So can you all see my slides? Yeah, we can see. Okay, cool, awesome. Hey everyone, thanks for taking the time to be here. It's good to be able to talk to you today. So yeah, as mentioned earlier, my name is Ivan Sim. I'm open source software engineer at Casting. And joining me today is Michael Kate, Senior Technologies from Casting. So today we will be talking about data protection workflows. So we're gonna start off by talking a little bit about running stateful workloads on Kubernetes and why we would want to do that. Then from there, we will have a brief introduction into Kubernetes container storage interface, also known as CSI, and how data protection fits into CSI. Then we will share with you some of the challenges that we have heard from our users who have tried to implement their own data protection workflows. From there, we will introduce you to Canister, an open source project by Casting that you can use to implement and curate your own data protection workflows on Kubernetes. After that, we'll dive straight into demo. And there are two parts to this demo. During the first part, we'll show you how you can use Canister to implement a data protection workflows to interact with the CSI snapshot APIs. After that, during the second part of the demo, we'll show you how you can scale out these data operations to run in parallel by using Canister and Argo workflows. Towards the end, we'll make sure they are sometimes taught Q&A. So why run stateful workloads on Kubernetes? During the early days of Kubernetes, many of us were told to use Kubernetes to primarily run stateless workloads, even though Kubernetes came with a collection of APIs and constructs to support stateful workloads. So we're talking about going back to the days of PET sets before it was even called stateful sets. And back then, we were told that when it comes to stateful workloads, we would be better off to use our managed charm data services. And fast forward to today, many things have changed, especially in the past year or two, we have seen an increasing trend in users running and scheduling stateful workloads to run directly on Kubernetes. Why did they do that? And why are we doing that? So for one, we like control over the compute specification. Maybe compute size in terms of CPU or memory, specifications or IOPS and everything and anything in between, it really boils down to cards. And we also like to utilize and depends directly on the Kubernetes neutral API. And we're not even talking about stateful workload related API. We're talking about scheduling APIs, like part disruption, budget, part affinity, anti-affinity, resource requirements and limits and load balancing, et cetera. For some of us, we may have more stricter requirements on the at rest encryption to be used for our data. And they might also stricter data sovereignty regulation that we need to comply with. At the end of the day, it really boils down to like who and how and where we handle and store our available customers data and who owns like the backup artifacts of all this data. If our databases were deleted, would still all these backup artifacts do accessible and exportable and importable. And more directly relevant to this talk is a neutral data protection strategy. So when we use like our managed data services inevitably like our data protection strategy would be like a couple to the stack, the API, the libraries of the providers. Now, this is not necessarily a bad thing. It really boils down to like the, our use cases and our requirements. For some of us, like I'm such a direct dependency, maybe okay for some of us, maybe not so. And even from talking to our users, one of the things that they did share with us about running a state for workloads is like, they regain that visibility and control into the upgrade mechanism. And in cases where things fail during an upgrade, the recovery and the road back is something that they may have control of, like when they run a state for workloads themselves on Kubernetes. So what has changed between those early days when we were told to use Kubernetes for stateless workloads only to today, where more and more of us are starting back to, starting to use Kubernetes to host and schedule our state for workloads. While there are many factors, we think like it really boils down to these two or three, like contributing topics here. The emergence of operator pattern has helped us up a lot in terms of automations of the installation, deployment and day two operations of data services and databases. And if we think about it, it makes sense, right? One of the main goals of an operator is to be able to encapsulate all this some specialized knowledge we have about the applications, about the data services and codify them and automate them and be able to share them with the rest of the team, with the rest of the community. And like there has also been tremendous, again, continuous growth and improvement of the Kubernetes Container and Storage Interface, also known as CSI. We talk more about CSI in the next slide. And we as a community, we have grown so much in terms of our experience and our expertise with running and managing like a co-operative state for workloads. Compared to the early days, we as a community are now more confident in our ability to debug containerized some state for workloads and manage them. And like on spoiler alert, like if we are using managed data services underneath it, like on this data managed, this managed data services are probably running on Kubernetes. So depending on how you look at it, there might be benefits in knowing like how Kubernetes schedule and run state for workloads, even though like if we choose not to do it ourselves directly. So it's almost impossible to talk about running state for workloads on Kubernetes without talking about CSI. So CSI is a standard of like API specification used to expose like storage solutions to containerized workloads and orchestration systems like Kubernetes. So it works really well on Kubernetes. It also works on like other orchestration systems like Cloud Foundry and Nomad. So CSI primarily manages like volume lifecycle with out of tree CSI drivers. Within the CSI framework, there is a collection of optional cycle containers managed by the CSI community. And this cycle containers, they're basically encapsulate common storage operations that you can embed and bundle with your CSI drivers. So for example, if you are a storage providers and you have like a collection of storage features you want to expose to your users, you will implement your CSI drivers. And then you will go to these some collections of cycle containers and pick and choose and bundle them with your CSI drivers to expose the kind of features that you want your users to have access to. And upstream like I'm with in the Kubernetes community, there have been a lot of effort and push towards like moving away from the entry like on volume plugins that come with Kubernetes to all these like out of tree CSI drivers. And some of the benefits of this push is pretty clear, so for example, we as users and implementers we are able to test and maintain and upgrade and grow the CSI drivers outside of the release cycles of the Kubernetes core. Now some of us might already be familiar with CSI for those of us who are fairly new to it. I want to just share some quickly, some useful features within the CSI framework that includes like volume expansion, like resizing of the volumes via the PVC API, step-shotting of volumes, cloning of volumes and initializing volumes with initial data using data populators. And more recently, like we have also seen like CSI driver that is capable of mounting secrets from your secret stores into your running workload via like CSI volumes. Now where does data protection fit in all of these? Within the SICKM storage, there is a working group that focuses on data protection. Last year, the group published a white paper on data protection workflows. And within the white paper, the group described like some relevant data protection features, including backing up of volumes, change block tracking to enable faster and more efficient backups, queers and unqueer hooks of your database applications, groupings of volumes and snapshots and API to interact with remote backup repositories. So you can export your backup artifacts to and this API to snapshots and backup applications. So if data protection is like relevant to the thing that you do on a daily basis, I encourage you to join like the Slack channel of the working group in the Kubernetes Slack. And I have also shared like the link to the white paper. So like feel free to download it and give it a read at your own leisure. So why bother with data protection? Why talk about data protection on Kubernetes today? Last year, the CNCF survey report shows that like 64.69% of these respondents said that they were either already running stateful applications in containers in Kubernetes or they are planning to shift and migrate their stateful workloads to run on Kubernetes. So that again, that has been the increasing trend for the reasons we discussed earlier. And we as a community also noticed that in the past couple of years, like the infrastructure at the architectures and the toolings and the support around like cloud native infrastructure and application. Architecture have grown and changed quite a bit over the past couple of years, whereas things related to data protection, the architecture, the toolings or the support around it has fallen behind. And we want to change that. And finally, like one thing that we really like about Kubernetes is that it provides like a set of APIs, a set of common APIs that different teams and different verticals within an organization can use to manage resources and enforce policies. And we feel like data protection solution should be managed the same way. So in other words, like there shouldn't be like repositories of YAMLs for our microservices and policies and all those things, whereas the data protection tools and scripts are in this separate repositories in different format with who knows who have credential access to them. So we want to be able to find a way to bring them together using a coercive like a cloud-native tools and APIs. And from talking to our users who have attempted to implement their own data protection workflows, we heard some of the challenges that they have encountered. At the end of the day, it really boils down to like the different requirements, the different strategies around snapshots and backups, that different teams with different experience and different scope may have different requirements on. For example, if you are someone who works on the platform team and you work closely with the cloud infrastructure, you might have APIs and tools that allow you to automate the snapshotting of the virtual disks that are attached to your nodes. So keep in mind that the snapshot captured at this level is usually crush level consistent only. So in other words, it means that data that has been persisted to disk get snapshot. Whereas data in memory or sometimes data in 10FS, they may or may not be included. Now, again, depending on your requirements like on your use cases, that may or may not be important to you. And as we move up the stack to the data services, to the specific databases, to our microservices, we might have like different sort of scripts to freeze and unfreeze the data service layers. We might have scripts that utilizes utility tools like MySQL DOM or PG DOM. And all of this like require like direct access into your production databases, right? Like how are they currently being managed? Who do you know? Who have access to what? And which versions which team are using? Overall, they're just way too many moving parts. And the analogy that we like to use is like imagine yourself being a barista with all these like lists of coffee types and on the menus with each with its own like ingredients and recipes that you have to memorize in order to put together like the coffee that your customer and consumer may ask of you. So just way too many things to remember and just way too many ways that things can go wrong. Okay. So this is where we hope like canister can come in to help you to implement and streamline your entire data protection workflows. So I'll let Michael talk us through like the internals of canister. Yeah, cheers Ivan. And I think the story that Ivan tells around data protection specifically around Kubernetes, this isn't a new like phenomenon at all. It's, this has been the same requirements around data protection, whether we look at other platforms, virtualization, physical systems, there's no shining on any particular platform that gets rid of that boring talk around backup. We still need to do it. In particular, when we think about data services, databases, Mongo, Postgres, et cetera, they still require that data protection and it's how far into those areas that Ivan touched on is really where like, how much handholding does it need through the process of protecting that data? Is a crash consistent copy going to be good enough in the light of some sort of fire flood blood type disaster almost to get our database back up? Because most of the time these databases are called like they're holding mission critical information in our environments. Okay, so I wanted to really hone in on why, what canister is, but also the why. Granted, everything that Ivan also talked about, so the application consistency, et cetera, can all be achieved via scripts, via like being able to hone in on a particular data service and be able to script that to the point that you get a copy of the data either via a snapshot or via an export, a tar file that gets exported out into object storage. But that just involved you knowing a bit more about a bit more things when it comes to Kubernetes. We already know that the ramp up from a Kubernetes engineer, Kubernetes administrator is already big enough. Like there's already big topics around networking, around storage in itself, around all other areas of Kubernetes. So really what canister does is kind of hit the easy button and takes away some of that knowledge. You don't really need to know everything about everything when it comes to protecting those potential mission critical data services. So we think about what canister is, it's an open source project maintained by Kastin who are focused on Kubernetes backup, but part of a wider company called Veeam. Veeam software have been around for 15 years, protecting virtual machines, physical, SaaS based workloads, et cetera. So, and really what canister is, is the focus on that application dataset, that application, whether it be Postgres, MySQL, I'll show you in a second, like the long vast amount of blueprints that already created that out there in the community, but really canister from a blueprint point of view or from an integration point of view could be anything in terms of protection. So really think of it as a way, as an open source project that enables us to take application consistency or application level copies of that data, export that, move that, wherever that needs to go. Again, abstract in a way that tedious, the tedious detail, so we don't need to worry about maintaining scripts or specific people scripts or the process around that. This gives us a way of being able to define what we want to do, how we want to do it and making that happen. When canister is deployed and we'll go through some of that process, but it's implemented, it's deployed within your Kubernetes cluster, access that Kubernetes controller, so it already integrates into that Kubernetes API. So it allows us to embed ourselves into the Kubernetes API and take advantage of all the good stuff there. And then this brings us back the extensibility of canister. I've mentioned some of the, like off the shelf or the community driven blueprints that we have, the MySQLs, the Postgreses, but really we can create a blueprint for any data service that is available and we do that via these functions that are built into the controller. So if we go next slide, Ivan. But if we just take one or two steps back and we start thinking about, okay, what does canister look like in terms of what can we do? So first of all, we have a blueprint, I've mentioned that a few times. Now, if we think of a blueprint as a set of instructions of, well, this is how I want to perform actions on a specific application. So again, we'll go back to like MySQL or Postgres, and this will say, I want you to pause the IO to our database. I want you to leverage a PG dump, and I want you to then export that out into object storage. Then what an action set then does is actually, okay, how do we make this happen? How do we instruct the controller to make that happen? Okay. Maybe just that output as to whatever that may be. So the action set is the, let's go and do it. It's the trigger. And then we think about a profile as in, where do we want to store that data, that R file or that export of that data? So three simple mechanics of what canister does and how we use that. Now also, so an action set, think of that as a backup, but also think of that as a restore. So we'd have a restore action set, a backup action set. And I think Ivan will touch on some of those other areas as well as we walk through the demonstration in a little while. We go next slide. So yeah, some of those canister functions, and this is just a small snapshot of the amount of functions that we have within canister. And in particular, the demo that Ivan's going to show is very much focused around using the create CSI snapshot, restore CSI snapshot. But it's also worth noting as well, we're seeing more and more customers that may be using Kubernetes. And this goes back to that stateless argument that Ivan spoke about, but where they use in or where you're using pass-based services such as Amazon RDS where you're going to store your mission critical databases. So canister has the ability to go outside of the cluster and be able to also capture that data as part of that process. Now, I don't believe we're going to show that in the demo, but I know that Vivek and other maintainers of the project have done various other CNCF webinars that specifically go into that RDS piece as well. So these are just some of the arguments that we have within each of those canister functions that enable us to perform specifics when it comes to things like CSI or RDS that you see on the screen. So there's a lot more canister functions. You can see that in the docs.canister.io. And basically these are all go, everything's written in go from a canister perspective. So if we go to the next slide, Ivan. So if we think about the architecture, so canister is deployed by a helm into our Kubernetes cluster and then we have this long list of blueprints that we can choose. So you'll know what application or what data service you're using. You can see here that we have Cassandra Elastic Search. Probably I've done a session as well from a CNCF point of view on Elastic Search, being that forgotten stateful workload that might live within your Kubernetes cluster, capturing all of that logs and the metrics around that. How important is that to the business? Do we need to protect that? And do we need to protect it in an application consistent pattern? So we've got that blueprint that will allow you to take that copy of that data but equally be able to restore that to that specific application consistent point in time as well. And you can see others in there, Mongo, MySQL, Postgres, et cetera. And this list has actually grown over the last couple of months with the community contributing back into these blueprints. Okay, so we've got two factors here. We've got our controller that's deployed as part of the into our Kubernetes cluster. And then we have a list of blueprints that are purely focused on our application and our data services within that application. If we go to the next slide, please Ivan. And then to trigger that, we have then an action set. Now, I mentioned about an action set being a backup or restore, but really that could be anything to verify or validate anything that we've done throughout the blueprint or trigger that blueprint, the set of instructions that we've defined in the blueprint. So if we go next slide again. So basically the controller is sat there and it's watching and waiting for an action set to be implemented or pushed into the Kubernetes environment. And then it says, okay, found that. We want to use this blueprint for that specific data set. Then we trigger that canister function, which is an exact function to the database or the data service in general to say, this is what I want you to do. And this is how I want you to play that. I want you to play through these steps. And I think the next slide or a few slides is an example of what that looks like. And then export those artifacts out. So whether that's a PG dump into a tar file or my SQL dump into a tar file, et cetera. We can export that out into an object storage location, for example. Next slide. So, and then we update what that looks like from an action set point of view, which gives us the ability to see the success rate of that action set that we triggered. And next slide. So, and if we think about what a restore looks like in terms of that, but just before we go to the demo which Ivan will actually show this is obviously from a restore action set, it's still, the controller is still waiting for the action set to trigger. And then, but then we're going to be pulling back the data from the remote storage into that database workload. But what Ivan I think is going to show is the ability to push that into it. So think about, not only are we talking about back and recovery of these applications, but think about a use case where we could copy that data and potentially expose that to a separate namespace. Think about the testing and cloning and leveraging that data is another use case that could be used here. And all whilst simplifying that, we're not complicating things while having to write these spokescripts for our application. So with that, I'll hand it back over to Ivan to get into the demo. Yeah, thanks, Michael. So yeah, earlier, like I talked about there will be two parts to this demo. And we will be doing the demo on an AWS and EKS cluster. And on the cluster, we have a Postgres database installed which has like PVC and PV attached to it and it's backed by an actual EBS volume. So during the first part of the demo, I'll show you how you can use Canister to interact with the CSI endpoint on Kubernetes and manage that the volume snapshot and volume snapshot content resources from there and to actually initiate the creation of an EBS some snapshots in the AWS some space. So I am gonna switch over to my terminal and if I do a kubectl get part in my PG SQL name space, you can see that I have a Postgres part managed by a stateful set workload running. If I run kubectl exact into the same part and pass in like a select star SQL query, you can see that I have some test data preceded into the database. And this data is what we are going to snapshot and restore later. Now I also have Canister deploy in the Canister name space and within the same name space, I have a blueprint called CSI snapshot. So let's take a look at what the CSI snapshot blueprints look like. As Michael mentioned earlier blueprint is a custom resource definition that comes with Canister. Within the blueprint, we have a collection of action. So lying to here's show a create snapshot action. If I go further down to line 47, there is a described snapshot action and towards the lower half of the screen, you see a restore snapshot action. So all in all, this one blueprint tells Canister, this is how you create and restore and list all the EBS snapshots via the EBS CSI driver. So within each action, we have faces. Let's scroll down a little bit. A face is a step, it's an atomic step that Canister would execute. A step is backed by a Canister function. So the first face here basically talks about like I'm putting my Postgres database into read-only mode and it's backed by a Canister function called QtExec. Underneath like this Canister function is a bunch of Go code that uses the same packages that Kupkato exact use to stream like remote command execution and to stream like output back from the pods. And the second face here is a lot shorter in terms of his YAML and it basically calls into a Canister function called create CSI snapshot. Again, underneath it, as you can imagine, it's a bunch of Go code that uses client Go to interact with the CSI volume snapshot and volume snapshot content APIs. So let's take a look at the action set that we are about. So we look at the blueprint. The next thing we want to do is actually use an action set to trigger the create snapshot action. And we're gonna use an action set called snapshot create. YAML is pretty relatively short, it's pretty simple. Basically, tell Canister to go and find this blueprint called CSI snapshots. And within the blueprint, there will be a create snapshot action. So execute that and pass in like a bunch of like input parameters into that functions. So we're gonna go ahead and create that. And then now we can quickly examine the status stop resource of the action set that we just created. If I scroll down to the lower half of the screen, you will see the status up resource of the action set is being populated with real-time state face, state information by Canister. You can see like within the two faces, like we successfully put the Postgres database into read-only mode. And then now we are talking to the CSI APIs. To say, hey, go and create a volume snapshot and the volume snapshot content resources. Now, if we were to take a quick look at the resources, you could see that like the volume snapshot resources was created just less than a minute ago. And under the ready to use column, Kubernetes is telling us that, hey, your snapshot is ready, your EBS snapshot is ready. Now, Kubernetes thinks that the snapshot is ready, but is it really? I think the best way for us to verify is to actually talk to the AWS API and confirm that the snapshot was indeed created. Now, I'm gonna run the get blueprint command again. And then if we go back to line 47, you will see that like under the describe snapshots actions, we essentially uses the AWS CLI to talk to the EC2 EBS snapshot API and say, hey, go find like the snapshots that we just created for this particular EBS volume that I know is attached to my Postgres database. Now, for demonstration purposes, I guess you passing like all this on batch scripts here just for visibility in a real serious environment, you probably would just curate and add your own like container image there to do all these things. The important thing is also to show that we can pass in like a secret references to secret resources from that already exists on our posture. So cool. Now, I wanna execute that describe snapshot action. So to do that, the first thing I would need to do is get hold off the EBS volume ID. So what this command did was it looked into the PV that is attached to my Postgres database and get the actual volume ID so that we can pass it into our described snapshot action set and just copy and paste this over here. So essentially what this did was we pass into we pipe into Kupkato create action set that is very similar to the first action set we use to create snapshot. We say go to blueprint CSI snapshots and run this describe snapshots function. And here's the volume ID that I wanted you to use. Now, if we take a look at the status sub-resource of the action set that we just created, we will see that we actually got response back from the AWS API. It just say, yep, I recognize this EBS volume and yes, you had a snapshot that you just created not too long ago. So there, Kubernetes said our snapshot is ready and AWS API confirmed that, you know, hey, this snapshot is also ready. So this goes back to what Michael talked about earlier. Like, you know, basically with canister blueprint you can use it to do many, many more things in addition to backup and restore. Now, the last thing that we need to do is really just to restore the EBS snapshot that we just created to a new instance of Postgres database. And to do that, I need to get hold of the actual create action set ID. Now, instead of pasting copy and pasting like a bunch of YAML that like I just did, I use this tool called canctl to create the restore snapshot action set. The interesting thing here is like, I'm able to tell canctl that says, hey, use the previously deployed action set as the parent or as the base of this new action set. So I pass in the dry run option just so that we can get a sense of what the YAML looks like. Now, if we look here, again, very familiar YAML properties, blueprint is CSI snapshot, run this restore snapshot action, pass in a bunch of input parameters and in addition to that, use this artifacts. So the concept of artifacts is like, so when the create action set snapshot finish a year, it has like a bunch of return values and outputs that got stored in this some status, some sub-resource. So canctl was able to go into that status sub-resource and read some out return values and inject it into my restore action set and use that as inputs so that I don't have to like figure out, okay, what were the return values I got back from the CSI endpoint. So I'm gonna go ahead and pipe this into keep cuddle and create this, okay? And let's take a look at the restore snapshot resource. If I can scroll down to the lower half of the page, there's only one phase here, which calls the restore snapshot function and the state is completed. So cool. So if I have done it correctly, then we should be able to see a new PVC in the PGC qual name space. So that's the one that we just created. So I can see like I was 30 seconds old. So the first son PVC is attached to our original Postgres database. This is backed by the PV and the EBS with the original data that we snapshot. Now the restore PVC is something that Ken has just created via the CSI API based on the EBS snapshot that we just created a couple of minutes ago. Now, this new PVC is gonna stay in the pending status until like a new Postgres part or instance is deployed and that's exactly what we're gonna do next. We're gonna use Helm to install like a separate instance of Postgres database in the same name space. The only thing to pay attention to here is like we are telling that the scheduler or the stateful scheduler to, hey, we used the existing PVC that we just restored. Don't create a new one based on your volume time template spec. So hit enter and then Helm is gonna go do his things and then if we watch the pot and the PVC, we will see that now the restore PVC is actually bounded to the pot because now that it's an actual consumer to use it. And then our restore Postgres database is coming online and if everything works according to plan, I should be able to cut out exact into it to see like the data that we just restored. So that is, this is, we're exacting to the restore pot and then like this is the data that we've managed to restore from our EBS snapshot. And you probably already noticed, right? All of these like without our user needing to know anything about CSI endpoint, needing to know about how to work with client go and stuff like that. So just YAML manifest and that canister like do all the low level like heavy lifting for you. Now, the second part of this demo is pretty straightforward. All we're gonna do is repeat the same data operation back up and then like let our go workflows like scale that out to run in parallel. So that we can snapshot multiple instances of Postgres at the same time. So I wanna show you what the workflow YAML looks like. So this is an Agile workflow YAML. The trick is that I'm able to pass in a list of stateful set workloads into the workflow. And as I go to this namespace, the three namespaces and find all this stateful set and do the operation that I'm gonna tell you inside the template. If you scroll down into the workflow template, we scroll down to the execution step. It's really just using canctl and say, now go ahead and create like action set for all this different Postgres database here. And then I can use the Argo CLI to submit the workflow YAML to Argo and let it like do its thing there. Sorry, well, I know that something happens there. So obviously that's massively important because not all of our applications are a single front-end container with a back-end database or data service. Nine times out of 10, your application, especially in a microservice is built up of many different data services. So being all in one succinct kind of like workflow, that's what the benefit here of incorporating something like Argo workflow into is allowing us to have group consistency across multiple data services or at least talking to multiple data services at once. Yeah, absolutely. And there's some spot on Michael, like just like using like Argo to help us to, just like the main thing here is with canister, it is a data protection workflows. It comes with all these data protection functions. Now, when it comes to more sophisticated like workflow concepts like running in parallel, like scheduling, retries, error handling, we can try to build all of these into canister or we can just utilize like a really cool project like Argo workflows, which is a more generic like workflow engine and you use them together to provide that really cohesive like integration, good point. So yeah, if we were to just take a look at the volume of CSI resources, we could see that like they have all, the snapshots have all been created by Argo workflows running in parallel across the different namespaces. So again, all of these without us having to manage like different bash scripts or make files, passing in different parameters or giving different teams, different users, different credentials access. So yeah, I think that's pretty much the demos before summing up like Michael, so anything you want to add? No, I think we've just covered a hell of a lot, right? We just went into a 101 of what canister is and what it does and why. Hopefully it simplifies that application focus around data protection. And then we obviously showed you how that looks and how it works. And then also incorporated that or integrated that into another open source project such as Argo workflow that allows us to not only orchestrate some of that data protection but also allow you to hit multiple applications or data services at one at the same time, whilst also being able to schedule that. So I think that's a summary that I'll give but I know this is pretty important to us and the community as well because this is a growing community for us and it's really the community that enables us to advance what we're doing from a canister point of view with what we're trying to do but I'll let you do the talk track here. Yep, sure. Yeah, so yeah, if you are currently planning and designing like a data protection workflows to protect your data, consider checking our canister.
