Friday Spotlight: Building the Modern Cloud-Enabled Data Center

Happy Friday!

Thanks so much to everyone that stopped by our booth and went to our sessions at LinuxCon North America 2015! We had a great time and it was fantastic getting the opportunity to meet and speak with many of you in person.

Some of the things that are top of mind for Linux users are (obviously!) the cloud impact on data center design, container technologies, OpenStack, security, and so on. So I looked through our archive to find a webcast that I think does a great job outlining how Oracle Linux approaches these things. If you're looking for a brief overview this Friday afternoon, head on over to this webcast archive and have a watch:

Building the Modern Cloud-Enabled Data Center with Oracle Linux 7

We'll see you next week!

Friday Spotlight: Oracle VM VirtualBox 5.0 is out!

Happy Friday!

I know a lot of folks use Oracle VM VirtualBox to run Oracle Linux VMs. I do this myself every day. The ability to run multiple machines with different operating systems on a laptop is incredibly helpful. For example, you can do Docker development in Oracle Linux on your Macbook. Or if you're running Linux as your main OS, you could have a Windows VM, maybe for some pesky corporate apps that won't run on Linux. The possibilities are just endless.

Oracle VM VirtualBox 5.0 was released this week, with a number of key features. Things like:

  • Runtime disk encryption
  • Drag and drop between nearly all host and guest combinations (including my typical Mac host->Oracle Linux guest setup)
  • USB 3.0 support
  • Headless launch support (say you need a local server VM running in the background!)
  • Performance improvements with paravirtualization for newer Linux and Windows guests

And a lot more.

Have a look at the Oracle Virtualization blog post for more details, and go grab Oracle VM VirtualBox 5.0 here.

Have a great week!

FRIDAY SPOTLIGHT: Getting Started with Docker on Oracle Linux

Happy Friday everyone! 

We have a great technical article for you this Friday.  In this article, you learn how to customize a Docker container image and use it to instantiate application instances across different Linux servers. This article describes how to create a Dockerfile, how to allocate runtime resources to containers, and how to establish a communication channel between two containers (for example, between web server and database containers). 

Ginny Henningsen quotes "Docker is exciting because it can easily capture a full application environment into a virtual container that can be deployed across different Linux servers. System administrators and software developers are learning that Docker can help them deploy application images on Linux quickly, reliably, and consistently—without dependency and portability problems that can inject delays into planned deployment schedules. Docker containers can define an application and its dependencies using a small text file (a Dockerfile) that can be moved to different Linux releases and quickly rebuilt, simplifying application portability. In this way, "Dockerized" applications are easily migrated to different Linux servers where they can execute on bare metal, in a virtual machine, or on Linux instances in the cloud. "

As shown in Figure 1, Docker containers consume fewer resources than "heavyweight" hypervisor-based solutions. Hypervisor-based solutions host a full-blown operating system instance in each virtual machine guest, but this also allows them to support different operating systems. (Oracle VM, for example, can host Oracle Linux, Oracle Solaris, and Microsoft Windows in virtual machines.)

Friday Spotlight: Optimizing Oracle Database Performance on Oracle Linux with Flash

Happy Friday!

This week, I'm dipping into the archives for a really interesting white paper, "Optimizing Oracle Database Performance on Oracle Linux with Flash." It talks about one of my favorite benefits of running Oracle Linux or Oracle Solaris with Oracle database called Database Smart Flash Cache. From the summary of the paper:

"This document explains how to increase Oracle database performance and improve user response time by deploying Oracle’s Flash Accelerator hardware with Oracle’s Database Smart Flash Cache feature. Oracle’s Database Smart Flash Cache feature is supported only on Oracle Linux and Oracle Solaris operating systems beginning with Oracle 11gR2.

The benefits outlined here apply to all Oracle Flash products on Oracle Linux or Oracle Solaris. For this particular study Oracle’s PCIe based in-server Sun Flash Accelerator F40 PCIe Card and Oracle Linux with Unbreakable Enterprise Kernel were used. The findings apply to both the Sun Flash Accelerator F40 and F80 PCIe Cards."

You can read the full paper here.

I also wanted to give a reminder for our webcast next week on Docker. This is a fantastic opportunity to learn not only how to get your feet wet with Docker and Oracle Linux, but you'll also learn the sorts of use cases where Docker really shines from one of our top experts, Avi Miller.

Friday Spotlight: Docker!

Happy Friday!

If you missed it yesterday, we did a press release describing the posting of Oracle Linux images on the Docker Hub Registry. If you're already working with Docker or interested in getting started with it, Oracle Linux gives you an extremely solid foundation to build on.

For a bit more on Docker, we did a webcast in November called Building the Modern Cloud-Enabled Data Center, where Docker and other trending topics were discussed. Have a view of the replay.

Also, did you know that you can bookmark tag searches on Oracle blogs? For example, to find posts on our blog about Docker, you'd use this:

https://blogs.oracle.com/linux/tags/docker

Click that link and bookmark it, and you'll always have the complete list of Oracle Linux Blog posts that mention Docker.
