Join Chaim Krause for an in-depth discussion in this video The SLES maintenance model, part of SUSE Linux Enterprise Server Essential Training.
- [Instructor] Let's now look at the SUSE Maintenance model. In order to do so, we have to go back in time and think about Linux when it started. It was basically for hobbyists. Many hobbyists continue to use Linux, and they get help from the community of other hobbyists. For example, to get support over IRC from a random, anonymous person is very common. Quite often, when I have problems, I will find the appropriate IRC channel and ask for help, and there'll be somebody there, who on their own time, will provide me with help to fix a problem.
Most of the time, it works. Sometimes, somebody who's a little overzealous provides you with what they say is an answer, and when you attempt it, it has side effects. That's where things change when you get into the business world. Because some commercial businesses want to take advantage of the benefits of Linux, yet have those guarantees that are required in order to run a profitable business. For example, let's take an Edge case.
If you're trying to fix your Raspberry Pi, and get it working with SUSE Linux, you'll look at forums, community forums, IRC, Slack, things along those lines. But if you're a business, and you would lose tens of thousands of dollars per hour if your SAP system goes down, then you need to get support from a reputable source that's going to back those services with a guarantee. Once you move into the commercial market, you enter the realm of contracts, contractual guarantees, legal definitions, legal responsibilities, and in some cases, really high amounts of money is at stake.
What SUSE does is take the Linux operating system kernel, and software that runs on that kernel, and back it by guarantees. Some of those guarantees are in the form of certifications. SUSE will certify hardware to be compatible with their operating system. SUSE will work together with hardware vendors, like IBM, to produce a package of hardware and software that they guarantee to run smoothly.
Not only are you getting the guarantees that the hardware will run smoothly, but you're also getting knowledgeable tech support representatives that work at those hardware companies, which will be able to help you when you have problems with SUSE Linux. Let's take, for example, myself. Many times, I have tried to get a piece of hardware working on my Linux system. I will call the support vendor, and as soon as I tell them I'm running Linux, they tell me it's not supported. They me that I need to be running Windows 10, or I need to be running Windows 7, patched to the current version.
I know that the hardware will work under Linux, I'm just having problems with a particular setting, and I can't get that from the vendor. With certification from SUSE, you won't have those types of issues. When you call and you say you're running SUSE Linux, they will provide you with the same support they would if you were running other operating systems. Besides hardware certification, there's many thousands of applications that have been tested and certified to run well on SUSE Linux. And along the same lines, those software vendors have been trained to provide you support using their software running on top of SUSE Linux.
You can also get help directly from SUSE themselves. Sometimes you have an issue and you don't know, specifically, where to go for help. You don't know if it's a hardware issue, you don't know if it's a software issue, whether it's something you need to configure in the operating system, or something you need to configure in the software running on top of that. But if you have SUSE Linux Enterprise, you have a maintenance contract, and you can call SUSE directly for help, and they will help you work out your issue. Each new release of SUSE Linux Enterprise is be supported for seven years.
What I mean by supported is that the patches, or bug fixes, and new features, are guaranteed, through a process of verification, that they will not cause problems with your existing SUSE installation. So if there's a bug that's out there, and it's something that's causing you problems, you wait for a verified patch to come out, you apply that patch, and SUSE is guaranteeing you that you won't have bad side effects. Beyond those seven years, there's an additional five years of continued support.
This is where SUSE will continue to support you running, but you very well may not get the patches or new features that you require. If you haven't already, this is the time that you should use to upgrade to a newer version of the operating system. As I said earlier, SUSE Linux Enterprise is a Linux distribution. That is a combination of the kernel and operating system, packaged with software applications. SUSE releases kernel and operating system patches on a regular but relatively slow schedule.
This schedule is often out of sync with the release cycle of the various software applications running on top of that OS. In a situation, you may find that you're hindered by a bug in a piece of software, but you can't wait for the next scheduled update of the OS, because you need to finish that project now. Or maybe there's a new feature in some software that you use that would make you more productive, or allow you to do something that was not even possible in the older version. Well SUSE is aware of this discrepancy, and has addressed the issue with modules.
Instead of leaving you no choice but to update the software application and suffer any bad side effects it may have on the rest of your system, SUSE's introduced these modules with SUSE Linux Enterprise Server Version 12. The modules allow for keeping clusters of software up to date without having to wait for the full release of the new version of the whole operating system. This allows SUSE to update software to give you access to those new features and bug fixes without losing the general support provided to the underlying operating system version.
To simplify things, you can basically say it's all about the money. The difference between loading up an open source kernel and running your business on it is that things are at risk. SUSE has stepped in as an example in the commercial market, where they take an opensource software and tools, and back them with legal guarantees expected by other commercial entities, so that there is reliability and stability.
