 Okay, oh there we are wonderful welcome welcome. So this session is about the certified open-stack administrator exam So is everyone here to learn about the COA? Yes, I know it's awesome fabulous. My name is Ann Bertusio. I manage the COA program at the open-stack foundation I know we're a little bit behind schedule So I'll probably hurry through a lot of my slides so I can make sure we get all of your questions answered My big goal of this session is to give you an intro about what the COA is about some updates That you need to know since the program is about a year old. We've made some updates recently They really make sure we answer all your questions about where do I find the COA? What do I need to know anything like that that's in the audience? So you buzz through those ones. How do I prepare these are some of the common questions we get most of the foundation? What's on it? What do I need to know? Am I really the right person to be taking it? So we're gonna answer all of those things So like I said the COA was launched at the Austin Summit last year So this it's it's a year old happy first birthday to the certified open-stack administrator exam We made it because at the time there was not a vendor neutral exam out on the market There are vendors who have their own exam But we kept hearing from community members and employers and hires that we would like a vendor agnostic standard Was what was looking for and that is part of our job as the governance body So we thought gosh we can we can make that happen. We can do that So this exam is also skills-based So there's no multiple-choice questions. You won't be sitting there matching project mascots to projects That's not really the point of it. The point is do you actually know how to use open-stack? We're not gonna grill you on do you know what the compute project is called for example, and you check ABCD It's really more. Can you actually spin it up and get it going and do what you need to do in a day-to-day environment? So why might you take it including even if you have an existing exam from another vendor? Like I said the biggest thing is that it is a vendor neutral and it is skills-based. So the certification transfers between open-stack platforms it transfers between distros and For many employers the skills-based thing is really the big thing. They're looking for they're looking for You know kind of a knowledge standard to know that You can arrive on the job and deliver what they're looking for It was created by the community with a group of developers operators admins from a variety of companies We had pretty good participation across the board So a couple things before we get to what's on the exam So I think that's what most people want to know so some quick announcements Right now the COA is on Liberty and very shortly hopefully by mid-June It will be on Newton for most people that's really not a big deal because the COA tests the core components of open-stack So some of those nuances between versions you're really not seeing most people don't notice but a lot of what is coming in mid-June are some User improvements, so we're gonna see a little bit quicker time in the test We're gonna have some just better UI experience overalls coming in mid-June So I would encourage you if you can wait about four to six weeks. I am I'm really excited to see this release come out I think you're really gonna like it and we also have two options now You can take it on Suza or Ubuntu so when it was when it was released It was just on Ubuntu and now you have two choices So obviously this is quite a bit And is there a second one? No, it's just the one so it's all jammed on there But this is all also available at open-stack.org Slash COA slash requirements, so I'd encourage you to go there rather than stressing about writing down every one of these But like I said, you can look across and get the gist that these are really the core pieces of open-stack like I said, we're not testing on those nuances between Between releases we're really trying to hit the big points from a high level of can you use open-stack? And how I would encourage a lot of people to practice is to go to that open-stack or slash COA slash requirements Just pull it up. It's all right there And if you can check off go through every one of those items and say I know how to do that I can do that you can even spin up dev stack and make sure you know what to do Then you're gonna be just fine We usually recommend that people have about six months of professional experience on open-stack before taking the test But people also feel confident if they've had a training You know there's even some classes this Week here at the summit people feel like if I've had a training I can go through and take the COA just fine as well So like I said how to prepare That's my recommendation to folks if you're not going to do a training or if you want to find out Maybe I need a training zip through those requirements or you can head to the marketplace Including the marketplace here at the summit and anyone who has a COA badge offers a training class That's tailored to taking the COA exam So those are people who are going to help you go through those requirement areas talk about what they mean And they know what's on the exam So they're the folks that can make sure that you're prepared to sit the COA and have success So the COA is a virtual exam, which means you can take it anywhere anytime comfort of your own home You just need a webcam a Microsoft not a Microsoft a microphone and a reliable internet connection You do need chrome or chromium So to register it's just open stack org slash COA and you will see a purchase exam button And at that point you can pick do I want Susie? Do I want you bun to if you are a student? You can get a price discount. You just need to show a valid student ID that has an expiration date on it So you need to be a current active student Otherwise for everyone else Open stack org class COA and one of the tricky things I try to remind people So once you purchase your exam you have 12 months to schedule it So you can purchase your exam today. It kind of gives you some accountability So you know you can make a goal sometime between now and next year. I have to take this exam So some people like that feature Holds them accountable for it So questions are there any questions and I also have sitting in the corner here with me is Chris Hodge if I can call you out He was one of the question writers on the exam So some questions he might be able to help us answer to Well, actually Chris, can I still you I think we're we're on YouTube. So if you want to come up here, yeah In general, no, it doesn't matter So most of the exam itself was written in the mindset that the open set client would be used there are a few instances where You can't necessarily accomplish something with one of the clients and we but we try to make sure that We spell that out so that if you have to go and say use the neutron client for something It'll actually say use the neutron client. So But yeah, yeah, if you're if you're comfortable with the open stack client then you You're even on the Liberty exam you're gonna be at a good place and you're gonna be in an even better place when the update happens Yeah, yeah, and those and all those are still available and one of the things about the exam environment, too is It We provide a bunch of the tooling there But if you are an expert user and you want to install your own packages the entire operating system is there and available for you to Work against it. It's it's an open stack ansible instance So all of the services are running inside of containers I there's there's only one question where we actually ask you to interact with the containers and again We give you the direct command and how to To to get to that container you know to do the task that's been requested and But but you but the exam is being served from inside of a boon to With open stack installed on open stack ansible. We also within the within the dashboard on any exam environment There's there's also a horizon instance. And so if you're comfortable doing some things with the horizon client That's made available to you also Yes, so your exam your certification does last three years at which point you will need to reset the exam Good question No, so if you take it actually unfortunately registration for here at the summit is closed But in future summits or future on-site exams you do need to bring your own machine Yeah, so so the exam is skills-based and When when when you are when you are done with the exam that environment it basically it's basically suspended And then it's handed off to a grading system that will go through and actually run open stack commands to check the state of the environment and so and so and so if you're working on a question that says you know start a server with this name and this Much memory in these properties it will then go and it'll query the open stack instance to see okay the server to see that you know the instance exists and has the properties that asked for and and and that's so You know that's that's how the exam is graded and so and that's why that's why you can use multiple clients We're not checking like what commands did you issue? We're checking to see is the final state of the system where we expect it to be Exactly yes, yeah, and and and this is a practical exam and so You know if you were to do something that horribly wedged your environment like you know You just shut down a service and everything broke and you couldn't proceed through the exam anymore That's actually you know a demonstration of the skills that you have broken your environment and So yeah, so it's a it's an actual You know it is a miniature Production system that you're working in And if you and actually if you're if you're curious about some of the some of the tools that we'd use in the exam I'm gonna be giving a really quick lightning session It's just gonna kind of run through like how do you use the command line client? How do you use horizon so you know just little 20 minute talk about that if anyone's interested? Yeah
