Servers: Canonical, Red Hat and SUSE

Container technology is one of the hottest topics in IT right now. Containers are user-space instances that allow programs to run in an isolated space; applications running in containers can only see devices and resources assigned to them. As containers share the kernel, albeit with some isolation, they're considerably lighter weight than virtual machines (VMs). Containers can be spun up quickly and because they don't consume the same resources as a full VM, many more containers can be run on a server compared to a full VM. Figure 1 is a gross oversimplification of how a VM compares to a container.

For the past couple of years, I have struggled with getting an operating K8s environment up and running, and I was surprised and pleased by how easy Canonical made it to install a K8s environment with MicroK8s. In this article, I walked you through how I installed a working K8s environment and the commands needed to verify that it is operational. In the next article, I'll show you what you need to do to get a K8s GUI up and running. In the last article in this series, I'll dive even deeper and explore how to use MicroK8s to run applications.

More recently, FINOS, which launched in April of 2018 to promote open innovation in the financial services community, created another project – the Cloud Native Computing Working Group. Chaired by Red Hat’s Diane Mueller, the group is working to define, build and maintain a collection of white papers and use cases that help members who are adopting containerized architectures. The group will also curate and promote the FINOS Service Catalog for use with the free, fully hosted Open Developer Platform on which FINOS members develop, test and collaborate.

We are happy to announce the release of SUSE OpenStack Cloud 9 Beta 7!
