Phoronix.com, a great site with an even better preformance test suite, has a nice write up about the often talked about BRTFS(commonly pronounced Butter FS). They mention that Fedora seems to be releasing it with GRUB extenstions to allow for file system snapshot roll-backs by the end of the year and Ubuntu by the 12.04 release next April. What is so great about this? Imagine if your favorite Linux Update tool could tell BRTFS to take a snapshot of the state of the file systems every time it did an update. Then let’s imagine that GRUB, our favorite boot-loader, could see that they were al there and give you the options to roll-back to that last know working version. Wouldn’t that just ROCK? No more worries about not taking snapshots on virtual machines or needing to restore after a bad upgrade on a physical machine. The time saved will be incredible. We can’t wait for this all to be production ready and standard on all Linux versions.

What is the best Linux Version for the Enterprise?
While Linux is taking the world by storm, I often get asked what the best version of Linux is for enterprises of all sizes. Red Hat, Suse and Ubuntu are always top notch distributions but then so are Fedora, CentOS, Mint, OpenSuse, and SlackWare. Which distro is the best depends largely on what software you will be running on your Linux installation. For most companies, standardizing on a distribution seems like it should be the final goal. As with most things we discuss, the answer is maybe as well as it depends. We are going to limit our scope in this CTO Brief to three of the top Business/Enterprise backed distributions.
Before we begin let us review what we mean by a distribution or distro. At their core, a distro is a collection of software packages and a Linux Kernel. At this point, almost every package available in one distribution is available in the others. Each tends to use and support either custom tools or tools that the leadership of the distribution believes are the best for the end user. The other noticeable difference between them is the UI or user interface. This can be as simple as the major color choice for the distribution or as intricate as including the path to get to your favorite applications in the app menus, or what side the minimize, maximize and close buttons are on. What really makes something an enterprise class package of Linux is the type and length of support you get from the distribution. Red Hat, SuSE and Ubuntu all offer between 2 and 5 years of support for certain versions of their respective distributions. This means that they will track, build, package and update all of the packages you get with the initial release. This often means that the new shiny features are not present. In turn this generally means that the system is better tested and more stable. You always have the option to upgrade any software to the latest and greatest versions. That does not mean however that when you call for support they will support you. With these long term releases they are making certain guarantees and because of that, they need to control as many variables as possible.
For this article we are going to focus on the three top corporate backed and supported distributions which are Red Hat, Suse and Ubuntu. These three are the broadly accepted as the leaders in this space. This does not mean that, for instance, FreeBSD or CentOS aren’t enterprise grade. I know several people that have been betting their businesses on them for the last few years with no regrets or major issues. So we will have a follow up discussion on these distribution’s next time with FreeBSD, CentOS, and Fedora/OpenSuse. We will try to point out how they differ. But for now, let us break down the first three distros and shine a light on what we believe are each of their strengths and weaknesses.
Desktop vs Servers
As you continue reading, we want to take a moment and point out that the focus is on Linux used on servers. The bias here is author based, not reality based. The focus in my career has been using Linux on servers. In the last three to five years, amazing changes have taken place in the world of desktop Linux. Some of the things that are happening will probably amaze even the most hardened Microsoft or Apple fan boy. The server side of almost any of the Linux distributions we are talking about in this article or the follow up next time has been production ready for years. Servers though do not have to have users typing on their keyboards or 16 USB Devices all hooked up through 2 ports on a PCI card. So while a distribution may excel in one area like servers, another may excel on the desktop. Red Hat and Suse are the ones in this article that do servers best. Ubuntu on the other hand shows us all what can be done with Linux running as a desktop operating system.
Red Hat was one of the first distro’s to do mass distribution right. While not the first, they have proven over the years that you can make money with free software. Red Hat’s leading position has ushered in several strategic partnerships with companies like Dell, IBM and HP. They have, over the years, used these relationships to build up a level of support from third party vendors that is the envy of all of the other distributions. When Linux is mentioned as a supported platform, most companies list Red Hat first, then any others they will also support. Red Hat has also realized and built update and deployment models that work well within most businesses. A new version of Red Hat may come out every year or so, but when you buy it, they will support it and provide security updates to the included software for at least the next five years. This stability has served Red Hat well and allowed them to again attract third part vendors to develop for Linux and specifically for Red Hat Linux.
Red Hat’s pluses are pretty simple and clear. They have a proven, tested and knowledgeable team of support people. They have by far the most experienced enterprise class support and have generally been the first distro to be supported by non-Linux development teams porting their applications over. It is rare that a developer or company will not support an application they say runs on Red Hat.
Red Hat does have a few negatives. The biggest negative is its price and pricing structure. Red Hat charges not just for the instance of Linux you installed, but there will be an additional fee for having a server with multiple cores. This can make the solution extremely expensive by comparison to Suse or Ubuntu. Red Hat is also extremely slow to adopt new features of the OS and other software. This may seem like a small thing until you want the latest and most stable version of an application. When a new file system like the btrfs(butter fs), with its cool new features that give teams the ability to roll back a file or entire system in seconds, Red Had users will have to wait for the next major release to see if it is included.
Suse was originally developed in Germany and various other countries in Europe to be the distribution for system administrators. In the early days, the administrative tools created by this distro were the best of the bunch. While still a leader in this area, several others have gained ground. Like Red Hat, Novell has used its connections to focus on large enterprise companies like IBM to create some custom solutions. For instance, they offer a special set of tools to help with Lotus Notes. Novell is also a sponsor of the Mono Project. Mono is a Linux compatible framework for Microsoft’s .net framework. There is even Moonlight, which is the counterpart to Silverlight, Microsoft’s answer to Adobe’s Flash tool set.
The stability of the distribution and its focus on providing enterprise solutions in line with those of its parent company Novell shine just as brightly. The integration with Novell’s Management Platform called Zenworks makes administering large numbers of servers very simplified. If you are just starting out with Linux, Novell offers a server creation tool called Suse Studio. This tool is a web based product that lets you create and test a server. Once you have all the packages and configuration set, you can then download a virtual machine or Anaconda file. This lets you get up and running quickly, while at the same time helping new users bypass a part of the learning curve associated in switching to Linux. The pricing on Suse Support is much more affordable than Red Hat. The packages that include the Zenworks Management product are still priced less than a hundred dollars. The pricing does change as you go above 16 CPU’s in a machine.
Suse has been picked on over the last few years because of its strong focus on attracting corporate or enterprise customers. They have made deals with Microsoft, they strongly support Mono Development, and they have developed tools to make other third party closed source tools work better like Lotus Notes. The other major concern with Novell at the moment is that they seem to be up for sale. While this is still a rumor, the big money is betting that a buyer will most likely split the divisions up and sell off the parts. This could mean that your support could slow or stop all together. The chance of it stopping seems unlikely as IBM, HP, or others will offer consulting as a replacement for the support you would get from Novell. The chance of being without updates or future enhancements is also small because of the work done on the OpenSuse project and the nature of Linux itself. Unlike Windows, remember Linux distributions can be forked/split and everyone can see the source code when it is published and released to the public. That prevents your investment in Suse from becoming useless. The community will rally around the old distribution and create a new one.
We at linuxinstall.net attribute a large part of the maturation of Linux as a Desktop Operating system to Mark Shuttleworth and the team at Canonical, the shepherding company of Ubuntu. While Novell and Red Hat have both provided extremely valuable contributions to Linux as a desktop operating system, Ubuntu has been the driving force behind the enhancements. Ubuntu was the first desktop distribution that I ever installed on a laptop with a wireless card where everything just worked. Where the server version of Ubuntu is concerned, the limitation they create during the install process can make it more time consuming to use in larger scale environments. This is largely due to having to install several features, like a non-standard Mysql database, or getting things like ISCSI to work, which takes a little more effort than on Red Hat or Suse. Ubuntu does seem to have heard the voice of the system admin’s in the crowd and are supposed to be bringing many new server focused tools and features to the next release due out in October 2010.
What makes Ubuntu unique is their attention to detail and approach to users. They have a meet up after each release to plan and discuss what should be in the next release. It is the little inputs from users that keeps Ubuntu ahead of the pack. With the latest release, one of the focus items was on Linux start-up speed. The goal was less than 10 seconds from powered off to up and connected to the Internet. This was accomplished and we as users are the ones that benefit. The details of how and why can be found here. They also provide all of their releases for free. The only time you have to pay Canonical is if you purchase their Ubuntu Advantage program. The real advantage is the fit, finish and polish on the desktop environment. They continuously focus on how to make users lives better.The Ubuntu Advantage programs are right in the middle and available from Canonical starting at $105 for desktop support and $380 for server support. Their pricing goes up from there depending on support hours desired and whether you want three years of support.
The problem with all of the polish and finish on the desktop side is that they have not spent a similar amount of time working on the server focused tools. If they stick to the recently discussed plans, they seem to be comfortable with where they are on the desktop. This should allow them to start to focus on the server tools they need starting with this Falls October 10, 2010 release. This is not to say that they have no tools for managing servers or workstations for that matter. Like Novell and Red Hat, they offer their own management service called LaunchPad. This is a great tool for smaller businesses that would probably be comfortable with cloud storage of the configs and such. However, not having it available as a purchasable software you can install on your hardware, it is probably not going to be wildly accepted for some security minded companies like Banks and Insurance companies.
The Final Verdict
We are going to rate each of them in 4 areas:
1) Software included – What software do they include in the package and is it current and stable?
2) Do they offer support and how competitive is it?
3) Deployment and Management Tools – How we rated the tools they offer after using them.
4) Third Part Software Support – How many vendors support them and what level of support do they get from non-Open Source solution providers?
|Distrobution||Software included||Support Available||Deployment/Management Tools||Third Party Software Support||Average|
With the right team administering your Linux machines, any of these distributions should be a great addition to your data center. While most companies want a goal of settling on just one, the reality is that for both cost and best of bread solutions, a mix is almost every one’s destiny. The experience of the contributors and friends of LinuxInstall.net is that forcing any third party company, even IBM or HP, to support a given distribution that is not their recommendation often ends in pain if not failure. While the differences are subtle with certain applications, those differences can determine whether or not you successfully deploy. What we are trying to say is to expect a mix of at least two of these distributions.
