(upbeat music) >> Welcome back to Boston, Massachusetts. We're here at the Seaport. You're watching theCUBE's coverage of Red Hat Summit 2022. My name is Dave Vellante and Paul Gillin is here. He's my cohost for the next day. We are going to dig in to the famous RHEL, Red Hat Enterprise Linux. Gunnar Hellekson is here, he's the Vice President and General Manager of Red Hat Enterprise Linux. Gunnar, welcome to theCUBE. Good to see you. >> Thanks for having me. Nice to be here, Dave, Paul. >> RHEL 9 is, wow, nine, Holy cow. It's been a lot of iterations. >> It's the highest version of RHEL we've ever shipped. >> And now we're talking edge. >> Yeah, that's right. >> And so, what's inside, tell us. to keep happy with a new RHEL release. to keep happy with a new RHEL release. The first is the hardware partners, right, because they rely on RHEL to light up all their delicious hardware that they're making, then you got application developers and the ISVs who rely on RHEL to be that kind of stable platform for innovation, and then you've got the operators, the people who are actually using the operating system itself and trying to keep it running every day. So we've got on the, I'll start with the hardware side, So we've got on the, I'll start with the hardware side, which is something, as you know, RHEL success, and I think you talked about this with Matt, just in a few sessions earlier that the success of RHEL is really, hinges on our partnerships with the hardware partners and in this case, we've got, let's see, in RHEL 9 we've got all the usual hardware suspects and we've added, just recently in January, we added support for ARM servers, as general ARM server class hardware. And so that's something customers have been asking for, delighted to be shipping that in RHEL 9. So now ARM is kind of a first-class citizen, right? Alongside x86, PowerZ and all the other usual suspects. And then of course, working with our favorite public cloud providers. So making sure that RHEL 9 is available at AWS and Azure and GCP and all our other cloud friends, right? >> Yeah, you mentioned ARM, we're seeing ARM in the enterprise. We're obviously seeing ARM at the edge. You guys have been working with ARM for a long time. You're working with Intel, you're working with NVIDIA, you've got some announcements this week. Gunnar, how do you keep Linux from becoming Franken OS with all these capabilities? >> This is a great question. First is, the most important thing is to be working closely with, I mean, the whole point of Linux and the reason why Linux works is because you have all these people working together to make the same thing, right? And so fighting that is a bad idea. Working together with everyone, leaning into that collaboration, that's an important part of making it work over time. The other one is having, just like in any good relationship, having healthy boundaries. And so making sure that we're clear about the things that we need to keep stable and the places where we're allowed to innovate and striking the right balance between those two things, that allows us to continue to ship one coherent operating system while still keeping literally thousands of platforms happy. >> So you're not trying to suck in all the full function, you're trying to accommodate that function that the ecosystem is going to develop? >> Yeah, that's right. So the idea is that what we strive for is consistency across all of the infrastructures and then allowing for kind of optimizations and we still let ourselves take advantage of whatever indigenous feature might appear on, such an ARM chip or thus in a such cloud platform. But really, we're trying to deliver a uniform platform experience to the application developers, right? Because they can't be having, like there can't be kind of one version of RHEL over here and another version of RHEL over here, the ecosystem wouldn't work. The whole point of Linux and the whole point of Red Hat Enterprise Linux is to be the same so that everything else can be different. >> And what incentives do you use to keep customers current? >> To keep customers current? Well so the best thing to do I found is to meet customers where they are. So a lot of people think we release RHEL 9 at the same time we have Red Hat Enterprise Linux 8, we have Red Hat Enterprise Linux 7, all these are running at the same time, and then we also have multiple minor release streams inside those. So at any given time, we're running, let's say, a dozen different versions of RHEL are being maintained and kept up-to-date, and we do this precisely to make sure that we're not force marching people into the new version and they have a Red Hat Enterprise Linux subscription, they should just be able to sit there and enjoy the minor version that they like. And we try and keep that going for as long as possible. >> Even if it's 10 years out of date? >> So, 10 years, interesting you chose that number because that's the end of life. >> That's the end of the life cycle. >> Right. And so 10 years is about, that's the natural life of a given major release, but again inside that you have several 10-year life cycles kind of cascading on each other, right? So nine is the start of the next 10-year cycle while we're still living inside the 10-year cycle of seven and eight. So lots of options for customers. >> How are you thinking about the edge? how do you define, let's not go to the definition, but at high level. (Gunnar laughing) Like I've been in a conference last week. It was Dell Tech World, I'll just say it. They were sort of the edge to them was the retail store. >> Yeah. >> Lowe's, okay, cool, I guess that's edgy, I guess, But I think space is the edge. (Gunnar chuckling) >> Right, right, right. >> Or a vehicle. How do you think about the edge? All the above or but the exciting stuff to me is that far edge, but I wonder if you can comment. >> Yeah, so there's all kinds of taxonomies out there for the edge. For me, I'm a simple country product manager at heart and so, I try to keep it simple, right? And the way I think about the edge is, here's a use case in which somebody needs a small operating system that deploys on probably a small piece of hardware, usually varying sizes, but it could be pretty small. That thing needs to be updated without any human touching it, right? And it needs to be reliably maintained without any human touching it. Usually in the edge cases, actually touching the hardware is a very expensive proposition. So we're trying to be as hands off as possible. >> No truck rolls. >> No truck rolls ever, right, exactly. (Dave chuckling) And then, now that I've got that stable base, I'm going to go take an application. I'll probably put it in a container for simplicity's sake and same thing, I want to be able to deploy that application. If something goes wrong, I need to build a roll back to a known good state and then I need to set of management tools that allow me to touch things, make sure that everything is healthy, make sure that the updates roll out correctly, maybe do some AB testing, things like that. So I think about that as, that's the, when we talk about the edge case for RHEL, that's the horizontal use case and then we can do specializations inside particular verticals or particular industries, but at bottom that's the use case we're talking about when we talk about the edge. >> And an assumption of connectivity at some point? >> Yeah. >> Right, you didn't have to always be on. >> Intermittent, latent, eventual connectivity. >> Eventual connectivity. (chuckles) That's right in some tech terms. >> Red Hat was originally a one trick pony. I mean, RHEL was it and now you've got all of these other extensions and different markets that you expanded into. What's your role in coordinating what all those different functions are doing? >> Yes, you look at all the innovations we've made, whether it's in storage, whether it's in OpenShift and elsewhere, RHEL remains the beating heart, right? It's the place where everything starts. And so a lot of what my team does is, yes, we're trying to make all the partners happy, we're also trying to make our internal partners happy, right? So the OpenShift folks need stuff out of RHEL, just like any other software vendor. And so I really think about RHEL is yes, we're a platform, yes, we're a product in our own right, but we're also a service organization for all the other parts of the portfolio. And the reason for that is we need to make sure all this stuff works together, right? Part of the whole reasoning behind the Red Hat Portfolio at large is that each of these pieces build on each other and compliment each other, right? I think that's an important part of the Red Hat mission, the RHEL mission. >> There's an article in the journal yesterday about how the tech industry was sort of pounding the drum on H-1B visas, there's a limit. I think it's been the same limit since 2005, 65,000 a year. We are facing, customers are facing, you guys, I'm sure as well, we are, real skills shortage, there's a lack of talent. How are you seeing companies deal with that? What are you advising them? What are you guys doing yourselves? >> Yeah, it's interesting, especially as everybody went through some flavor of digital transformation during the pandemic and now everybody's going through some, and kind of connected to that, everybody's making a move to the public cloud. They're making operating system choices when they're making those platform choices, right? And I think what's interesting is that, what they're coming to is, "Well, I have a Linux skills shortage and for a thousand reasons the market has not provided enough Linux admins." I mean, these are very lucrative positions, right? With command a lot of money, you would expect their supply would eventually catch up, but for whatever reason, it's not catching up. So I can't solve this by throwing bodies at it so I need to figure out a more efficient way of running my Linux operation. People are making a couple choices. The first is they're ensuring that they have consistency in their operating system choices, whether it's on premise or in the cloud, or even out on the edge, if I have to juggle three, four different operating systems, as I'm going through these three or four different infrastructures, that doesn't make any sense, 'cause the one thing is most precious to me is my Linux talent, right? And so I need to make sure that they're consistent, optimized and efficient. The other thing they're doing is tooling and automation and especially through tools like Ansible, right? Being able to take advantage of as much automation as possible and much consistency as possible so that they can make the most of the Linux talent that they do have. And so with Red Hat Enterprise Linux 9, in particular, you see us make a big investment in things like more automation tools for things like SAP and SQL server deployments, you'll see us make investments in things like basic stuff like the web console, right? We should now be able to go and point and click and go basic Linux administration tasks that lowers the barrier to entry and makes it easier to find people to actually administer the systems that you have. >> As you move out onto these new platforms, particularly on the edge, many of them will be much smaller, limited function. How do you make the decisions about what features you're going to keep or what you're going to keep in RHEL when you're running on a thermostat? >> Okay, so let me be clear, I don't want RHEL to run on a thermostat. (everybody laughing) >> I gave you advantage over it. >> I can't handle the margins on something like that, but at the end. >> You're running on, you're running on the GM. >> Yeah, no that's, right? And so the, so the choice at the, the most important thing we can do is give customers the tools that they need to make the choice that's appropriate for their deployment. I have learned over several years in this business that if I start choosing what content a customer decide wants on their operating system I will always guess it wrong, right? So my job is to make sure that I have a library of reliable, secure software options for them, that they can use as ingredients into their solution. And I give them tools that allow them to kind of curate the operating system that they need. So that's the tool like Image Builder, which we just announced, the image builder service lets a customer go in and point and click and kind of compose the edge operating system they need, hit a button and now they have an atomic image that they can go deploy out on the edge reliably, right? >> Gunnar can you clarify the cadence of releases? >> Oh yeah. >> You guys, the change that you made there. >> Yeah. >> Why that change occurred and what what's the standard today? >> Yeah, so back when we released RHEl 8, so we were just talking about hardware and you know, it's ARM and X86, all these different kinds of hardware, the hardware market is internally. I tell everybody the hardware market just got real weird, right? It's just got, the schedules are crazy. We got so many more entrance. Everything is kind of out of sync from where it used to be, it used to be there was a metronome, right? You mentioned Moore's law earlier. It was like a 18 month metronome. Everybody could kind of set their watch to. >> Right. >> So that's gone, and so now we have so much hardware that we need to reconcile. The only way for us to provide the kind of stability and consistency that customers were looking for was to set a set our own clock. So we said three years for every major release, six months for every minor release and that we will ship a new minor release every six months and a new major release every three years, whether we need it or not. And that has value all by itself. It means that customers can now plan ahead of time and know, okay, in 36 months, the next major release is going to come on. And now that's something I can plan my workload around, that something I can plan a data center migration around, things like that. So the consistency of this and it was a terrifying promise to make three years ago. I am now delighted to announce that we actually made good on it three years later, right? And plan two again, three years from now. >> Is it follow up, is it primarily the processor, optionality and diversity, or as I was talking to an architect, system architect the other day in his premise was that we're moving from a processor centric world to a connect centric world, not just the processor, but the memories, the IO, the controllers, the nics and it's just keeping that system in balance. Does that affect you or is it primarily the processor? >> Oh, it absolutely affects us, yeah. >> How so? >> Yeah, so the operating system is the thing that everyone relies on to hide all that stuff from everybody else, right? And so if we cannot offer that abstraction from all of these hardware choices that people need to make, then we're not doing our job. And so that means we have to encompass all the hardware configurations and all the hardware use cases that we can in order to make an application successful. So if people want to go disaggregate all of their components, we have to let 'em do that. If they want to have a kind of more traditional kind of boxed up OEM experience, they should be able to do that too. So yeah, this is what I mean is because it is RHEL responsibility and our duty to make sure that people are insulated from all this chaos underneath, that is a good chunk of the job, yeah. >> The hardware and the OS used to be inseparable right before (indistinct) Hence the importance of hardware. >> Yeah, that's right. >> I'm curious how your job changes, so you just, every 36 months you roll on a new release, which you did today, you announced a new release. You go back into the workplace two days, how is life different? >> Not at all, so the only constant is change, right? And to be honest, a major release, that's a big event for our release teams. That's a big event for our engineering teams. It's a big event for our product management teams, but all these folks have moved on and like we're now we're already planning. RHEL 9.1 and 9.2 and 8.7 and the rest of the releases. And so it's kind of like brief celebration and then right back to work. >> Okay, don't change so much. >> What can we look forward to? What's the future look like of RHEL, RHEL 10? >> Oh yeah, more bigger, stronger, faster, more optimized for those and such and you get, >> Longer lower, wider. >> Yeah, that's right, yeah, that's right, yeah. >> I am curious about CentOS Stream because there was some controversy around the end of life for CentOS and the move to CentOS Stream. >> Yeah. >> A lot of people including me are not really clear on what stream is and how it differs from CentOS, can you clarify that? >> Absolutely, so when Red Hat Enterprise Linux was first created, this was back in the days of Red Hat Linux, right? And because we couldn't balance the needs of the hobbyist market from the needs of the enterprise market, we split into Red Hat Enterprise Linux and Fedora, okay? So then for 15 years, yeah, about 15 years we had Fedora which is where we took all of our risks. That was kind of our early program where we started integrating new components, new open source projects and all the rest of it. And then eventually we would take that innovation and then feed it into the next version of Red Hat Enterprise Linux. The trick with that is that the Red Hat Enterprise Linux work that we did was largely internal to Red Hat and wasn't accessible to partners. And we've just spent a lot of time talking about how much we need to be collaborating with partners. They really had, a lot of them had to wait until like the beta came out before they actually knew what was going to be in the box, okay, well that was okay for a while but now that the market is the way that it is, things are moving so quickly. We need a better way to allow partners to work together with us further upstream from the actual product development. So that's why we created CentOS Stream. So CentOS Stream is the place where we kind of host the party and people can watch the next version of Red Hat Enterprise get developed in real time, partners can come in and help, customers can come in and help. And we've been really proud of the fact that Red Hat Enterprise Linux 9 is the first release that came completely out of CentOS Stream. Another way of putting that is that Red Hat Enterprise Linux 9 is the first version of RHEL that was actually built, 80, 90% of it was built completely in the open. >> Okay, so that's the new playground. >> Yeah, that's right. >> You took a lot of negative pushback when you made the announcement, is that basically because the CentOS users didn't understand what you were doing? >> No, I think the, the CentOS Linux, when we brought CentOS Linux on, this was one of the things that we wanted to do, is we wanted to create this space where we could start collaborating with people. Here's the lesson we learned. It is very difficult to collaborate when you are downstream of the product you're trying to improve because you've already shipped the product. And so once you're for collaborating downstream, any changes you make have to go all the way up the water slide and before they can head all the way back down. So this was the real pivot that we made was moving that partnership and that collaboration activity from the downstream of Red Hat Enterprise Linux to putting it right in the critical path of Red Hat Enterprise Linux development. >> Great, well, thank you for that Gunnar. Thanks for coming on theCUBE, it's great to, >> Yeah, my pleasure. >> See you and have a great day tomorrow. Thanks, and we look forward to seeing you tomorrow. We start at 9:00 AM. East Coast time. I think the keynotes, we will be here right after that to break that down, Paul Gillin and myself. This is day one for theCUBE's coverage of Red Hat Summit 2022 from Boston. We'll see you tomorrow, thanks for watching. (upbeat music)
