 How is everybody doing? Good show so far, everybody? All right. So we are here to present a cloud migration framework for OpenStack. I'm Sri Ram. This is David Paraza. I just want to take a minute of your time to talk to you about persistent. We are a powerhouse of software development. We've been around for 24 years. We've been contributing to the OpenStack community since the Bazaar cactus days. And we are very excited about the amount of workloads that are moving to OpenStack. And we'd like to grease the skids to get more of your workloads on to the OpenStack platform as quickly as possible. And David and Aditya are going to walk you through what we've done so far. And we'll wrap it up and have some questions that you will answer, questions that you have. David? Thank you Sri Ram. So I'm David. All right. So these are the things that we're going to discuss today, right? So we're going to go through some of the drivers, challenges and complexities that migration has. I have to say, this is not the normal, you know, migration within a cloud where you, you know, get a host for maintenance and you migrate the VM to, you know, take the host down. That's not the migration we're talking about. We're talking about onboarding, migrating virtual machines or physical servers into a cloud environment, okay? So that's what CloudJump does. And we're going to talk to you about CloudJump in the context of, in the generic context, but then we're going to bring it down to, you know, how it works in the context of OpenStack. And, you know, migration services that we can actually provide with this tool, right? So what are the main drivers? I mean, why do people need this migration? Well, it's a simple pain point from our customers. It's a simple pain point probably from your customers. You know, I hear all about this great cloud, but I have current workloads and I have current hardware. You know, what about my investment, my current investment on infrastructure? How does that work? How does that play here? So these are, you know, one of the main drivers we have. We also have agility, you know, the ability to do hybrid models. You know, sometimes you want to start private and then all of a sudden you want to move that workload into a poly cloud environment, right? The whole value proposition of hybrid cloud environments. So you don't want to, you know, if you have a lot of on-premise workloads and, you know, all of a sudden you see that some of these workloads are not, you know, sick. They don't have to follow some compliance and, you know, it's easy to migrate off. You use this tool. One of the main things also is, you know, the vendor lock-in. You've been hearing throughout the conference, right? So this is one of the value propositions of OpenStack. This, you know, OpenStack is, you know, an operating system. It's a framework. It allows anything to play here, right? So you can have hypervisors, you know, for Microsoft, Hyper-V. You can have VMware, vCenter, or you can have, you know, all the open source, you know, KVMs and, right? And, you know, the whole value proposition is you don't have to be locked into a specific hypervisor vendor or a specific network provider, right? Or a specific switch vendor, right? You have multiple options. So one of the things is for you to give you those options, you know, one of the first things that come on is you have to migrate, you know, from your existing workloads into your current cloud. But not only that, what if you move to another cloud? You know, another cloud provider, let it on. You might as well just move that VM as well. So this also helps you with that, right? So the pay-as-you-go model and, you know, you have two choices. You either build from scratch or you migrate. And then migration is what we're going to propose here. So what are the complexities, right? So you have physical environments, you know, capturing that, you know, thankfully there's already off the shelf tools from Red Hat and others that we can use to do that. So, and, you know, the other things is not only the virtual machines, but what are the network topologies around it and, you know, the storage that is attached to that virtual machine. That's something also you want to migrate. So it's not, it's not only that disk image that we move, we move all the metadata around that, right? So, you know, it's a complex end-to-end of a migration. You know, usually it takes even more than one people or one person, you know, a lot of time to bring everything together, right? So do the capture and the source. Bring the image into the next one. So deploy it using the target, the target cloud tools. Then come in and, you know, add the new configuration which matches what you used to have, right? So that's part of the complexity too. And then the minute you do push button, you know, it's really, there's a lot of things going under the hood. Adjid is going to take you through what's going under the hood and then you'll see all the complexities that come with that. So here's, you know, the life cycle, right? So what happens is you have an existing shop where you have, you know, VMware, maybe Microsoft and maybe you even have OpenStackPrivate, right? So we have a tool that actually does inventory. We collect all the metadata about that and then it brings that information to a cloud migration engine. The cloud migration engine enables all this metadata and then creates templates. You see how that works. And then, you know, with those templates and the actual raw material, the actual images or disk images, then you can play a whole, you can replay the whole environment on premise into a cloud, right? So how it works. So it's a per VM tool, right? So you do this for every VM you have to do, you have to migrate it. Now, like I said, there's a discovery and there's also agents. So we can deploy this as a virtual appliance, right, in your cloud. So there's agents that are in charge of the customer data center and there's agents that are in charge of the cloud, the target environment, right? And then they all have their own functionality. One speaks, you know, the API of the cloud. The other one speaks, you know, current, current libraries, you know, like libvert or ESX in that on premise environment. So the engine, like I said, collects the information, creates the templates and moves it. So what are the steps, right? So you have to capture at some point. It's not, you don't have to do it in a sequence. You have to, you can capture, I mean, the engine, what it's doing, you can capture and then, you know, create, you can create assets in the public cloud. Capture and then eventually what you need to do is to enable those virtual machines in the new environment. You need the whole, you know, forklift and he's going to explain that in a moment. But I want to give you a preview here. To transport all the resources and all the actual bits, right? Into a source VM. But you also have certain capabilities you can add here, which is not only you can move the virtual machines, but you can, let's say you want to add a new monitoring application on top of that. You have an, you have an opportunity here to add to those VMs using these tools. So you can add, you know, let's say a new Apache API that allows you to come in, right? So or you have a new monitoring, like I mentioned, new login, you know, more events that you want to collect. This is a good opportunity to do that. All right? So with this, I'm going to let Ajita take you through the fun part, which is the actual tooling and what it does, okay? Thanks, David. Hello, everyone. So customers today want to migrate their workloads and migration and, you know, upgrades are a great topic in this conference. So customers want to migrate, but they're just not happy with, they don't want to stop at migration. They want to see what tools offer after, you know, migrating workloads. So traditional approaches of migration, you know, just captured workloads, captured VMs, moved them onto the target cloud, but that was it. Then they relied on DevOps mechanisms to, you know, go and adjust to see if the workloads were compliant, if they were running as they were on premise. So customers want more than mere transport and forklift of VMs. So the framework that we're going to talk about, you know, allows, has a capability of actually plugging in custom recipes to, you know, do adjustments, adapt to how you want the workloads to adapt in the target setting. So a typical migration is characterized by, you know, capture on-premise VMs, transporting of those into your target cloud and, you know, adjusting them onto your target cloud. So we're going to talk about the technology that we've built here at Persistent. It's called CloudJump. We typically don't want to offer this as a self-service portal, primarily because we think that migration is not as easy as it sounds. Migration is kind of a complex task, and it's very important for a migration engineer or a domain expert to help the customer understand what needs to be migrated, how it needs to be migrated, and what is the baggage associated with your migration in terms of attached networks and storage. So we offer a self-service GUI. We offer customer portals and a system admin portal to facilitate the migration. Our migration engine is based on workflows. As we saw, migration is complex end-to-end workflow, but we want to try and break this entire workflow into smaller, sizable, easy-to-execute chunks, which are pretty much orchestrated using our workflow engine. We introduce a new notion of migration using certain templates. So our migration engine has the capability of ingesting some metadata, creating templates on the fly, and executing those in order to facilitate your migration. Our entire stack has agents, which are basically orchestration agents which sit on premise as well as in the cloud to do its respective functions, which are pretty much a very, very lightweight in nature based on REST APIs. We're going to talk about the multiple cloud migration scenarios, which are relevant to OpenStack. We also want to talk about how we can facilitate multiple migrations from a single portal. We can have a concurrency enable there. The entire stack that we've built is based on all the industry standards, primarily open source. We have REST-based APIs. We use LibWord to do the underlying system calls. We use Apache LibCloud for doing some inter-cloud mechanism, and our stack is based on Python libraries. And in the end, we talk about the fun part, which is actually integration with Amazon CloudFormation and OpenStack Heat. So what are the cloud migration combinations that are relevant to the OpenStack and AWS space? So we know that AWS is probably an undisputed leader in the public space, and OpenStack is getting there in the private space. So it becomes a very, very natural model for customers to have the best of both the worlds. And in the context of a hybrid scenario, customers who are using OpenStack, they probably want to move to AWS. So we capture that as one of the potential combination. We also facilitate the movement of vanilla KVM environments and ESX environments onto OpenStack private environments. So I've been speaking to customers and people here at the conference who are very interested in understanding how to move from plain vanilla via ESX environments onto OpenStack. We also talk about moving workloads from an OpenStack private environment to another OpenStack private environment, maybe across versions, or maybe across multiple zones within the same data center. The interesting use case that we are currently working on is moving from an OpenStack private environment to OpenStack public. So we are looking at rack space as a potential use case here. That's WIP stands for Work in Progress. And the fun part which I've encountered over the last few days while talking to people is they want to understand how they can move workloads from AWS back into OpenStack. After the workloads reach a certain level of maturity in AWS, how do they bring them back? So that's something that we're exploring at this point in time as well. So shaping the target deployment. Customers who want to move on to target environments via migration may or may not envision how their target deployment should look like. So for example, you have a customer or you have an environment which has typically, say, 50 to 100 VMs. It's a fairly midsize deployment. It is very important to understand how you want this particular on-premise environment to look in the cloud because you have virtual machines, you may have physical machines, you have attached volumes and networks. And it is very important for people to understand how to derive a map of replicating or cloning your existing on-premise infrastructure onto a target cloud like AWS or maybe even OpenStack. And here we look at the typical intricacies of IP addresses, virtual networks, subnets, routers and firewalls. It's very important for them to understand how they can configure and recreate all of those onto the target platform. So at times when I've been speaking to many customers, they don't really envision or they don't really know what they want or how they want their environment to be set up on the target cloud. And this is where the role of the migration engineer comes into picture, who is the domain expert. So let's talk about one of the use cases which is OpenStack to AWS migration. So we've all, you know, learned about, heard about AWS cloud formation, OpenStack heat. And we've seen people, you know, leverage all of those in typical orchestration, creating environments, you know, doing software configurations. We saw, we heard Steve Baker talk about how you can do software configuration using heat yesterday. So what we're trying to introduce a new perspective here by saying that, you know what, let's try and leverage cloud formation for doing cloud migration. So the way we do it is, if you want to, say, move two of your virtual machines into a target cloud, at design time, our tool allows you to actually pre-create your stack, your target stack, from our console rather than go into the Amazon console and creating the stack there and associating your forklifted VMs to that stack. So what we do is we have the metadata that we, you know, import into our migration engine, which creates these cloud formation templates on the fly and executes those templates at the hit of the migrate button. So the workflow is pretty much characterized by creating a stack and then capturing your source VMs, forclifting them into the stack that you've already created. This actually makes your migration very less complex and very, very seamless. So in this particular use case, we're looking at two VMs that you want to migrate using a template that we've created and the template actually creates the stack that you see here. So the stack is pretty much straightforward. You have a single subnet within a virtual private cloud on Amazon, which is sitting in the US East region. So once the stack is created, the VMs are ready to be forklifted and all of this can be done using a single touch, using a simple push button approach. So here I'm going to introduce you to the tool. So migration is characterized as a three-step process. It's basically importing your VM metadata of your source, source VMs, who are potential cloud candidates. So in this particular UI, you see that you can import your cloud candidates by either connecting the tool to an inventory analysis database who can fetch and who can basically analyze what the, who the cloud candidates are. So you can fetch that metadata by hitting the import VM button on the top left. Additionally, you can also add your metadata manually by hitting the add button on the bottom. So for example, if the system admin just gives you an Excel sheet, you can just go and add your VM data there. Then we talk about configuration. So what is configuration in the context of migration? You basically need to point your source VM. You basically need to tell your source VM where it is going to go to. So we are talking of, say, Amazon AWS as a target cloud. The zone would be Northern California within EC2. And what kind of flavor the VM needs to take once it moves onto the cloud. So these are the typical mandatory parameters that are required to initiate a basic migration. And here you see that there is a stack associated with the particular migration. So the stack is something that we create at design time even before we schedule the migration. So if you do not create a stack, the particular migration will have a default stack, which basically is forklifting your VM into Amazon with its default properties that Amazon provides. So for example, if you move this with a default stack, the particular VM that will be forklifted into Amazon will have a public IP address exposed over the internet. But if you want to have your VMs or a set of VMs or your applications in a specific network topology with specific firewall security groups, you can pre-create that entire network topology at design time using this tool. So for that, you may have to go to the AWS stack plus button on top and try and create a stack. So here you can see. So the basic underlying assumption here is that you as a customer, you are having an AWS account and you can validate. You can basically add your keys in the account details button out there in the rightmost tab. So here we are talking about creating a stack. Basically, in this particular use case, we're going to talk about creating one virtual private cloud within Amazon, creating two subnets, and trying to move a VM into these two subnets. So we add all the requisite parameters required for creating a stack, which is basically the VPC name, the sitter, and the internet gateway name. And as you see here, once the stack is created, we actually create a blueprint of what your target topology can look like at design time itself. So the migration engineer along with the customer can actually validate this by creating a VPC subnets and any resources that can be created using these templates. And once this particular blueprint is validated, it can be saved as a template within the migration engine. You can also edit a particular VM template, a migration template that you've created. You can assign different stacks to it. You can assign different IP addresses and so on. So once you configure this, your VM is typically ready to be migrated. So what you need to do next is you need to go to the Migrate tab and associate. And here you can see the particular VM that we are trying to migrate is associated to a specific stack that was configured in the previous step. So every VM can be associated to a stack. So there's multiple relationships there. So we are offering a push button technology here to actually import, configure, and migrate from the same console, wherein you can do intercloud stack creations, intercloud migrations. The migration output here you see is basically a color-coded legend which talks about all the different individual steps that are characterized by the migration. A migration, like we said, is a complex process. So we are trying to break down what each of them looks like. So it basically starts by connecting to the host, your source host, trying to capture it, copying it to a local depot within your source environment from where it can be for uplifted for some obvious reasons. And then you can create a stack and then finally import the VM into that stack. So we know that migration is a very, very complex process. And it's very important for the migration engineer to know why things are failing, if they are failing anywhere. So we've also provided a framework to show the logs and debug these logs whenever there is a failure. So what actually happens under the hood? So we have this portal that we saw which basically allows you to import data, configure VMs, and then create stacks. So what exactly happens? So we are basically creating metadata, ingesting them into the workflow engine, and asking the workflow engineer to create these templates on the fly and execute them. So if you look at the migration of OpenStack to AWS, basically we are creating CloudFormation templates on the go and creating these stacks and then using our migration templates to actually forklift your source VMs into the stack that we've created using CloudFormation. So we did this for CloudFormation and Amazon. And we realized that, you know what? This is working. And this is excellent. And this is very useful in the context of migration. So why not do something similar for OpenStack? And then we explored doing the same using heat. So we've seen the different use cases of heat yesterday. And this is one use case that we want to talk about in the context of migration. So everything is pretty much standard, except the fact that we are using heat templates and heat orchestration to actually facilitate the creation of stacks and migration. So what does the heat template look like? And what does the orchestration look like in the context of the migration? So you have a heat template here, which is basically a heat orchestration template, hot template. And you can see here that we are actually instructing. So the user is actually instructing the migration engine to create a network, call new network, and to create multiple subnets within that network. So basically what this means is that the customer wants to move his two VMs into these two subnets that can be pre-created using the tool. So how does this work? So you can extract these inputs, which is basically the metadata. And the heat client can call the heat APIs by passing this yaml file. And the heat API ultimately talks to your Neutron over our sender to do the actual orchestration. So let's talk about a use case with respect to OpenStack now, where the OpenStack is a target cloud. So we are talking of moving a vanilla KVM or ESX environment onto OpenStack. So what do we do? So CloudJump is our tool, which is typically deployed in the source environment. So you have raw images based on KVM, and you have VMDKs, which are running on the ESX infrastructure. So CloudJump is ingested with the metadata, the source VM metadata. And it basically goes and captures those. But we are also talking of stack creation. In order to create new stacks on OpenStack private environments, you need to talk to Keystone on the target platform, authenticate with the tokens, and basically get a handle of all the other components, that is heat, Neutron, and Glance. And the way we orchestrate is by creating this network stack that you see on the right-hand side, which is similar to the one that we saw in the previous slides. And then use our Glance APIs to copy or forklift the images into the Glance repository. And then use heat to actually boot that VM from the Glance repository into the stack that we've created. Here we talk about moving from an OpenStack private environment to another private environment. So if you see clearly, the left-hand side is what changes. The right-hand side is pretty much the same. In this case, you have an OpenStack environment in your on-premise data center. The left-hand side changes in the context of you don't have a v-center or a KVM VM manager to deal with. You have your plain Nova, Glance, and Keystone to interact with. In order to first connect to your on-premise system, you need to authenticate with Keystone on your on-premise and then get handled over Nova and Glance to basically do the forklift onto your target. Again, here we're using Keystone on the target to ensure that we are able to do the orchestration on your target cloud. And this is what we're exploring at this point in time. We know how to do this. We've actually done a part of this. So what we are doing is we are migrating our OpenStack on-premise workloads into RaxSpace. So we are leveraging PyRax APIs to do this. So PyRax basically exposes APIs to forklift VMs into the RaxSpace cloud file, which is basically an object storage. So what happens after you move into the cloud file? You have to register your particular image in the image store, and only then you can boot from that particular image store into Nova. So the part on top has been automated. And now what we are looking for is some kind of support from RaxSpace to understand how heat is actually used in RaxSpace and what kind of support do they have for orchestration. So once we understand this, it's going to be very easier for us to actually integrate this part into our tool to facilitate a one-touch migration to RaxSpace, just like we've seen for AWS. So we've been able to cover ground so far. And the next thing we thought about was what can we do? What else can we do? What's next? So what we've done is we've actually integrated our Cloud Jump tool into Horizon. So this is what we see. You see a Cloud Migration tab on the bottom left, which basically shows our Cloud Jump user interface. We've done all the styling. We've integrated the tool using the Python Django. And our next step is to actually try and facilitate the migration of workloads from the UI itself. And there are multiple ways in which it can be done. So as a community member, I'd like to ask if such a service is going to be vital. We know it is vital, but how can we incubate a migration as a service with an open stack? So it has to be either done basically using another project within the community, or we can, as persistent, we can have a patch as an add-on utility to work with the Horizon setup. So we also have designed certain wireframes and certain ways in which we can actually facilitate the migration. So here you see the complex workflow is actually broken down into sub-steps. And this is what we are planning to do in Horizon now. So Sriram is going to talk about next steps. Sorry. Cool. So we went through a lot of stuff. I know it's a little bit we are here to answer questions. You may have noticed that Aditya used AWS as the starting point. And we didn't mean to end up here, but just that we started with AWS. We saw that the open stack community code base and infrastructure is similar to what we found in the AWS space, and we were able to replicate that with ease. That kind of shows the maturity of what the community has achieved so far. And now as to the next steps, what we are thinking about doing is fleshing out the rest of the work in progress pieces that we have, bringing AWS to open stack and the other work in progress thing. We also would like to improve the velocity in terms of how quickly we can move things back and forth. And that actually is an important aspect of the freedom that open stack provides that not only are you not locked into a particular environment or a solution for a long time, you are also able to move quickly. So it's easy to say you're not locked in, but it takes you two years to migrate out of it. That's kind of saying you cannot migrate out of the current solution. So we want to increase the velocity. We want to increase the ability to move friction free in a multi-cloud environment. And then also looking at migration as a service that Aditya was mentioning, is it a part of something that should be a first class citizen within open stack itself? What would that look like? We would really like to participate and shape that discussion as well. Thank you, and if you have any questions, please step up to the mic. So all this was very interesting. Is this on? Yep. Okay. But in terms of being able to use migration, you might need to predict what the migration overhead is going to be. I think this is out of scope for what you were trying to do, but there's all sorts of migration policies that you might want to use to manage what gets migrated when. So being able to have an accurate model of what the migration overhead is going to be is going to be necessary for building a variety of number of different migration policies. So have you looked at being able to predict what the migration overhead is going to be and could you use your templates to help make those predictions? Because in terms of the memory footprint, number of open connections, attached storage and all those things that you mentioned, those things would affect what the overhead would be. Yes, the assessment tool that we went through that captures the metadata from the performance metrics, that actually passes the metadata of the performance metrics of each of your workloads and that goes into the sizing decisions that we can make. Yes, we can do that. It's not directly exposed right now, the ability to project the overheads in the target template, but it can be very easily made available. Yeah, I mean, this actually sounds like a great suggestions actually, right? So instead of a question, it looks like you're feeling back to us. It would be nice, yes. Yeah, well, all the mechanics that you described are certainly the first things that you have to do, but in terms of being able to manage capacity and new capacity planning and all that kind of stuff you need to get some sort of automatic policy that you're in. The policy sounds to me like a more encompassing abstraction than just a template for VM or a couple VMs, right? So some people might want to say, I want to migrate this whole chunk of the cloud, right? Which is usually, I mean, in our experience, you know, with our customers, usually it's good to have a one by one migration. So, you know, it's gradual. It's not something that, you know, you could still work in your current environment, we're gonna migrate this VM, and then this all the VM. And then you can have a plan and a timeline, right? Yeah. Like the same, you do any other project. Yeah, yeah. For a large enterprise. But good suggestion. I mean, yeah, it'll be super cool. You said you're going to do the object store migration, like where you captured the image and then migrated to, what about the block storage, right? Yes. For the volumes which are attached to the VM. Yep. What's the question, though? So how do you migrate the attached storage? The block storage. Yeah. Do you want me to answer? Okay. Okay. So obviously, Cinder's involved, right? So, and, you know, the way it's happening now is because we're, for example, we get VMware. And VMware, you can have, you know, VMDK is pretty much, you know, it's not the same model as Cinder block storage. So you just have, you know, another VMDK and that's your extra volume, right? Right. Now, we can easily move that from, you know, one target environment, one source environment to a target environment and then, you know, make this VMDK an extra volume. And so what we're thinking is what's going to happen is since we're going to target a lot of the Cinder to Cinder, Cinder has a lot of drivers that is actually block storage. So it's not a file, right? So you can just move a file that we do with VMDKs. So what's going to happen is you're going to have to have an intermediate dump of that data into some sort of file that we can move, right? So we're welcome to, you know, all the suggestions, anything that can quickly move, for example, from Cinder private to another private, right? Some sort of rapid connection. We can, we're open to do that, right? So, but the initial thing, the initial idea is to just dump it into a file and then move it. That's the simplest thing to do right now. So is it going to be an offline migration or is it a live migration wherein you're at? It's not live, so it's completely offline. So, and this is an important point. I don't want people to get confused while these guys do live migration, you know? This is a completely new VM with a completely new domain, right? So you're going to have to, you know, if you have, if you have, you know, a domain name, you might need to change the IP in a domain name and things could continue to work. So it's not, it's not a, you know, live everything's working now, it's working exactly the same. I mean, that's a use case, that's another use case. It's a use case we're not targeting and it's a use case that, you know, works well when you do maintenance and other things like, you know, also for disaster recovery. I mean, so as a host goes down for HA, right? Host goes down, VMs can migrate very quickly. That's our scenario. Thanks for your questions. If we answer your question. We are actually also, you know, migrating block volumes. It's the script that we're looking at also right now. Yes, I was wondering if you guys have benchmarked this against any other kind of migration strategies, for example, we just recently migrated a small project from one cloud to another. It was just one server and then a hundred clients and we just glanced, we just took a snapshot, glanced them down to our management, working glanced back up to another one and had them up and running. We had it about done about 35 minutes. And so I was just wondering if how, how would this help us in our, like how much time would this save us if we implement it? Yeah, I mean, the time that it saves is not really on, I mean, again, we have one requirement that's improved velocity, right? So, which is part of, you know, the tweaking that we have to do to actually get better performance. But the time you're saving is tremendous just because of, you're not doing manual steps, just because of the automation part, right? So if you're doing it manually, it still takes time for you to move, you know, 10 gigabytes from one environment to another over a network, over any network, right? What we're saving is the human error. We're saving the actual human interaction that has to come in and run the commands. So we're automating all that. And we're doing it, you know, I like the presentations just to them hit, right? Because it was pretty, it goes with what we're doing here. It's like, you wanna save things into a file. And then that file then is something that you can take and play anywhere, right? And then, so, we haven't done any benchmark in terms of performance. That's something that's coming, you know, next just because we wanna improve our current performance. But we've seen our customers, you know, increase their time to the cloud dramatically, you know? From days to, you know, hours, right? Go ahead. Hi there, excuse me. I like to add a point. So another important thing is that, you know, the forklifting time is something that is always a function of your network and the size of your VM, right? I mean the size of your disk file that you're trying to forklift. So that is something that is always gonna be constant for any migration strategy. But like you mentioned, you know, we are trying to eliminate and we are trying to reduce the manual intervention time and the time that is actually created in validation and creation of your stack onto your target cloud, which can be actually done at design time using an easy to use interface. Does that answer your question? Yeah. It does. Suppose I have an application deployed on an open stack cloud and the application consists of several compute nodes and backend services like Trove database. So have you, are you guys also thinking of migrating the entire application from one cloud to the other? Yes, absolutely. So basically an application is, you know, characterized as a collection of VMs. So all of them can be imported together in the import stage and you know, they can just be forklifted as an image. So are you saying can be forklift an application itself? Yeah, I mean it'll consist of database migration as well, right? The Trove database. So we do get Trove is something that's on our roadmap to do. So if you have a Trove database, yes, we'll have to, just as we are syncing up to Glance to kind of launch the copy of the images, we'll use the Trove to move it from Trove to, I mean, open stack to open stack is easy. But moving it from say Trove to RDS is gonna be, is a mapping that we have to do. All right, thanks everybody. Have a good rest of the show.
