Omair explains .NET Core versions and components at Red Hat Summit 2017 in this lightning talk.

A lightning talk from Red Hat Summit 2017. Here is the transcription:

[00:11] I have a VM here. Let me just run the .NET command to show you. It's not there, so we're going to install .NET on RHEL. The first thing I'm going to do is become Super User, otherwise I have to type pseudo for every command and that's just a hassle.

[00:33] I'm just going to copy and paste the commands here. The point isn't that I type out every command, the point is that you see it's only a couple of commands to get it installed. The first thing I'll do is get my subscription manager attached to the correct pool of RPMs, that's the packages I pulled down.

[00:49] When you install .NET on RHEL you're getting the package from Red Hat. You're not getting it from Microsoft. We get the source code from Microsoft and then we build it to run on RHEL. Red Hat packages are, I like to say vetted. That is, we test them and make sure they work really well so you're not just pulling down software and hoping it works.

[01:12] Now I'm going to enable the repo. I've attached to it and now I have to enable it. Notice at the end where it says, "RHEL 7 Server..." There's also a work station, and there's also one for an HP [high performance] special computing thing that I'm not really familiar with. The point is you're probably going to use a RHEL server to install .NET.

[01:26] One of the cool things about the new .NET core as opposed to the old one is the new .NET is much smaller. Whereas before, when you installed .NET, you would drop in a DVD, or a CD, and wait forever for it install, and you would get 4 gigabytes of .NET. Now it's just a couple hundred megabytes.

[01:49] I'm going to YUM install this scl utils. It doesn't matter what they do. They just enable installation. Let's just leave it at that. There's nothing to do because I've done that before, but that's OK. It's better to have nothing to do than to skip the step.

[02:08] Now here's the actual install itself. I want you to notice it's just a command line and it's a YUM installed .NET core 1.1, which is version 1.1. It's going to go up to the inner webs and pull down everything it needs to install it.

[02:17] Your limiting factor here is going to be your Internet speed. Other than that, that's it for installing .NET. It really is that small and that fast. After it's installed, you have to enable it to be available in Bash. Once that's done, we'll bring it up and we'll see .NET.

[02:36] One final step here. In just a few minutes we went from not having .NET...I don't know if I can copy and paste here, bear with me.

[02:47] It's enabled. Now we should have .NET command available. There it is. We'll do a .NET new which will create a new program. The first time you do a .NET new it's going to run this little expand. That might be considered the final step of installing .NET, that's it. That's all you have to do to install .NET, that's it.

Thank you.

When is free Linux more expensive? When you have an enterprise to run. Every IT organization is looking for ways to be more efficient. What you may not realize is that pieces of your infrastructure like community Linux are actually making your job more difficult. Red Hat can help. This video demonstrates how standardizing on Red Hat Enterprise Linux can save your organization money and make you more productive and more efficient.

Putting technology in front of a wide audience quickly is part of the open source model, as seen in the 'release early, release often' mantra popular among open source developers. This community collaboration results in more feedback about feature functionality, and more opportunities for developers to continually improve code. Red Hat participates in this process as part of the Fedora community, and its contributions to Fedora help enhance the technology selected by Fedora's substantial user and contributor base. Fedora and Red Hat create a more scalable, extensible, and interoperable Red Hat Enterprise Linux.

How do you modernize your datacenter while maintaining the integrity of your current system? Red Hat Enterprise Linux offers stability and reliability on a single, open platform, so you can focus on the projects that add value to your business.

Senior Software Maintenance Engineer Neil Horman from Red Hat demonstrates cgroups, a generic mechanism the kernel provides for grouping of processes and applying controls to those groups. The grouping is done via a virtual filesystem called 'cgroup.' Within this filesytem, each directory defines a new group. Tunables within a cgroup are provided by what the kernel calls 'controllers.' Each controller is able to expose one or more tunable or control. When mounting the cgroups filesystem, it is possible to mount the filesystem several times, with each mount point having a different set of (non-overlapping) controllers. The key idea is that this allows the administrator to construct differing group hierarchies for different sets of controllers/tunables, which offers new ways to control and manage cloud resources.

Secure-24, a Red Hat Certified Cloud Provider, partners with Red Hat to ensure stability, scalability and security with Red Hat Enterprise Linux, Red Hat JBoss Middleware, and Red Hat Satellite.

Adobe Systems, a long-time user of Red Hat® Enterprise Linux®, wanted to offer its enterprise customers easy access to sandbox resources to evaluate and prototype solutions using Adobe products. Turning to the cloud, Adobe used Red Hat Enterprise Linux and Amazon Web Services (AWS) to not only deliver a sandbox solution, but also to offer customers a Software- as-a-Service (SaaS) option for deploying Adobe-based solutions. Today, Adobe is using the Red Hat platform and Amazon Web Services to help customers simplify deployment, lower cost of ownership, and accelerate time to value.
