Training Thursdays: Get Trained on Docker and Oracle Linux

Docker is an open platform management tool for Linux Containers. It provides a means for developers and system administrators to build and package applications into lightweight containers. The container is independent from the host operating system and kernel version. As a result, you can run the same application, unchanged, on laptops, data center virtual machines, and any cloud. You can transfer this container to another machine that runs Docker and run the application without any compatibility issues. The following lists additional advantages of running applications within Docker containers:

  • Docker images contain only the content needed to run an application so they are smaller than virtual machines, which require the entire operating system.
  • A Docker container runs faster than an application that includes the overhead of an entire virtual machine.
  • A Docker container includes its own network interfaces, file system, and memory, which allows the application running in the container to be isolated and secured from other processes on the host computer.

You can learn to use Docker with Oracle Linux, as well as learn about many other topics, by taking the Oracle Linux 7: Advanced Administration course. You can take this course as a:

FRIDAY SPOTLIGHT: Why Oracle Linux for Modern, Cloud-Enabled DataCenter?

Happy Friday everyone!

We have a great video to share with you this week. In this animated video,  learn how Oracle Linux includes the features and tools you need for your modern, cloud-enabled data center. 

While Oracle Linux is open source and includes standard technologies, tools, and features, Oracle extends the release to deliver a complete, integrated, and supported platform for performance-driven production workloads. In addition to the Red Hat Compatible Kernel (RHCK), Oracle supplies the optimized Unbreakable Enterprise Kernel (UEK), which was first developed to support highly scalable Oracle Engineered Systems. Support for Oracle Linux is affordable and the release is free to download and distribute, unlike other commercial Linux distributions. To add even greater value, Oracle bundles additional capabilities—Ksplice for zero-downtime kernel updates, support for Docker, Linux Containers, OpenStack, Oracle Clusterware for High Availability (HA), and more—at no additional charge with an Oracle Linux Premier Support contract. As a result of these additions, companies receive greater value from their Linux support investment, allowing IT organizations to achieve a higher return on investment.

Watch Oracle Linux for the Cloud-Enabled Datacenter.

FRIDAY SPOTLIGHT: Best Videos about Oracle Linux from OOW15

There's something better about hearing a topic in a video, it is as if you have been transported to that location without interruptions from other elements. You also get to know the presenter at a different level; how he gets excited about his products, his projects or the environment around him. For this reason, we wanted to dedicate this Friday to all the Oracle OpenWorld videos that feature Oracle Linux.  It will give you an amazing insight and transport you to San Francisco, to that moment!

Keynotes: 

First we want to start with Oracle OpenWorld 2015  keynotes that have featured Oracle Linux announcements. We recommend watching Larry Ellison and Intel CEO, Brian Krzanich's keynotes.

theCUBE Videos 

The second video set is Oracle Executives that are featured in SiliconAngle's theCube. Wim Coekaerts, Sr.VP of Linux and Virtualization Engineering, had been very busy during Oracle OpenWorld this year with some great interviews. His videos are always fun to watch and very informative about latest technologies like docker, containers and OpenStack. The second video is from our Chief Architect, Edward Screven. You can hear his views on Open Source in the video below.

Partner Videos from the Showcase 

Our third video set covers some of our great ISV and IHV Partners who have participated in our OracleLinux, Oracle VM and OpenStack Showcase.
