Friday Spotlight: A busy week, and Spacewalk and Ksplice

Happy Friday!

With Oracle OpenWorld Latin America with several Oracle Linux and virtualization sessions and demos, and our booth at Red Hat Summit, it’s been a busy and fun week here at Oracle.

For today's spotlight, I’m going to reach back into the archives to highlight something that I think is particularly cool. You probably know about Spacewalk for managing your Linux deployments, and you also probably know about our Ksplice feature that allows for zero-downtime kernel updates. Taken together, these tools give you a streamlined way to keep your Oracle Linux systems up to date. And, in fact, this past winter we did a webcast on this exact subject, which is available as an archive. It would be nice background listening as you wrap-up your Friday afternoon:

Spacewalk and Ksplice: Keeping Oracle Linux Systems Up to Date and Secure (webcast archive)

See you next 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: Oracle Linux 7 - Optimizing Deployment Flexibility and Increasing ROI

Happy Friday!

Our spotlight this week is a fantastic new white paper called "Oracle Linux 7 - Optimizing Deployment Flexibility and Increasing ROI". From the summary:

"This paper describes Oracle Linux 7 features that help IT organizations deploy strategic applications effectively and efficiently. It discusses the advantages of choosing Oracle Linux and how the operating system brings value to enterprise application delivery. It also explores versatile technologies that are supported with Oracle Linux (such as Linux Containers, Docker, Oracle VM, and OpenStack) that allow IT architects to choose how best to deploy and meet requirements for agile cloud and virtualized application environments."

Have a look for some Friday afternoon reading.

See you next week!

Friday Spotlight: The Power of The Ksplice Feature of Oracle Linux Video

Happy Friday!

I'm really excited to share this week's Friday Spotlight with you. Oracle Senior Vice President of Linux and Virtualization Wim Coekaerts sat down with Director of Product Management Michele Casey and Senior Development Manager Jamie Iles to talk about Ksplice.

In the video, they go into a lot of detail about why Ksplice is a production-ready tool for keeping systems up to date. A highlight for me is the discussion featuring a real world example of an Oracle Linux 6.2 system from 2011, and how a system like that can be patched over time with all the important CVEs and security updates without a single reboot -- no rebooting literally for years. For production systems, you can just keep the system up and running, and still be up to date. Click this screenshot to head on over to Oracle Media Network to watch the video:

We'll see you next week!

Friday Spotlight: Oracle VM Templates Economic Impact Assessment

Happy Friday!

I wanted to bring your attention this week to a brand new paper called "Deploying Oracle RAC using Oracle VM Templates—An Economic Impact Assessment." In the paper, Evaluator Group took a look at Oracle VM Templates with Oracle RAC versus user-created VMware templates. From the paper:

"Evaluator Group studied the creation and use of virtualized server templates as an administrative process for server deployments in an Oracle RAC environment—a process that can be surprisingly complex if done manually within any database environment.

This study was done in two ways:

• Evaluator Group conducted an independent lab comparison of template creation methods in an Oracle database application environment. We first built templates 'from scratch' and deployed virtualized servers for Oracle RAC under VMware while tracking the time consumed for each step in the process. We then repeated the same process of deploying virtualized Oracle RAC servers, but in this second iteration we used Oracle Virtual Machine (Oracle VM) and the templates that are included with Oracle VM to create clones of virtual machines. Again, we tracked the time consumed for each step in this process.

• We also interviewed an Oracle systems administrator as a basis for additional comparison of building templates in a production environment. For this customer, templates were a “game changer” because of an ability to deploy database and business intelligence services up to twenty times faster for their customers.

Evaluator Group conducted this study of both methods to compare the two on the basis of management complexity, risk resulting from administrative error, and overall time consumed."

One of the really cool things in this paper is some real world data from a customer using Oracle VM and Oracle Linux and the total cost of ownership reductions they were able to achieve. Have a read of the full paper.

Have a great week!
