FRIDAY SPOTLIGHT: Oracle Private Cloud Appliance: Key Benefits for Partners

Oracle Private Cloud Appliance, formerly named Virtual Compute Appliance, simplifies the way customers install, deploy, and manage converged infrastructures for Linux, Windows, or Oracle Solaris applications. Oracle Private Cloud Appliance was built as a highly available system to run a range of workloads. To accomplish this, all the elements in the system are redundant, such as power, networking, compute, management & storage. All of your application services are configured in software and connected together using the built in Software Defined Network. If there is a node failure all of those services will be automatically moved to another node. Here are some key benefits for customers:

  • Turnkey cloud in a box at industry-leading price point
  • Simple path from on-premise to Oracle Cloud
  • From power-on to production in few hours
  • Enables linear scalability by adding one compute node at a time
  • Enhanced security with Oracle’s hardened software stack 

It comes pre-installed with Oracle VM and Oracle VM Manager and choice of downloadable Oracle Linux, Oracle Solaris andOracle Enterprise Manager 12c.

In this blog, we specifically wanted highlight benefits to Partners. We have interviewed Rich Mason, Sr. VP Oracle Linux, Virtualization and MySQL Sales, and Wim Coekaerts, Sr. VP Oracle Linux, Virtualization Engineering, to understand some of the key benefits for partners. Watch this video to learn about how Partners can take advantage of some of the features it offers.

There are many service opportunities for partners with the Private Cloud Appliance. Here are just a few examples:

In many cases end user customers will require some assistance to migrate their existing applications to the Private Cloud Appliance, and the Reselling Partners will naturally be in a good position to offer those application migration and consolidation services. Partners can also offer VMware to Oracle VM migration services

Partners can also create software templates for their customers as well as customize Oracle VM templates for their customers’ specific workloads.  The use of templates dramatically speeds up implementation and rapid rollout of new applications and services.

By using the Oracle Enterprise Manager software that comes as part of the Private Cloud Appliance, Partners can also build and manage private cloud services to their customers.

We have seen partners using the Private Cloud Appliances for Managed Services, Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS). In North America, Secure-24 and Tier1 Inc. are examples.

Visit Oracle Private Cloud Appliance website to get more details.

systemd, The New System and Service Manager in Oracle Linux 7

Oracle Linux 7 includes systemd, the new system and service manager that replaces the Upstart init daemon. While providing backward compatibility for legacy Oracle Linux 6 service scripts. systemd offers the following benefits over init:

  • Services are started in parallel wherever possible using socket-based activation and D-Bus.
  • Daemons can be started on demand.
  • Processes are tracked using control groups (cgroups).
  • Snapshotting of the system state and restoration of the system state from a snapshot is supported.
  • Mount points can be configured as systemd targets.

Friday Spotlight: Why Virtualization Drives the Cloud

Happy Friday!

We have a brand new digital white board video for you this week on why virtualization drives the cloud. The host is Oracle VM Product Management Director John Priest, and while the video is focused on Oracle VM, it has some great general purpose information in it, too. It would be interesting to folks interested in Oracle VM, Oracle Linux, and just cloud infrastructure in general.

Click here or the thumbnail below to head over to Oracle Media Network to give it a watch:

 Hope you enjoy it and have a great week!

Oracle Linux Users Participate in Salary Survey

Linux is one of the hottest buzzwords in IT hiring. If you can prove that you know your stuff when it comes to Linux, then you can command a fat salary. And what better way to prove that your skills are up to snuff than with a certification?

How much can you add to your income with a Linux certification? Contribute to getting an accurate answer to this question by taking a minute to fill in this survey: http://certmag.com/salary-survey-plus-linux/. The results will be available in the August edition of the Certification Magazine.

Being one of the top Linux curriculum in the industry, the Oracle Linux certifications will feature in this survey.

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: Shiny new pages for OSS, Public Yum, and ULN!


Happy Friday and a happy holiday weekend to those of you in the US!

It might be obvious, but the Oracle Linux and virtualization teams are heavily involved in open source. For quite some time, we’ve had a site that describes the open source projects the teams are involved in. This site was just updated with a new look and feel and additional content. My favorite part is a history section going by to 2001. Check it out:


I’m also excited to highlight the new look and feel for the Oracle Linux Yum server (we also call it "Public Yum"):


And you also might not yet have noticed that the Unbreakable Linux Network ALSO has a shiny new look and feel:


Just some improvements to make working with these sites easier for folks. We hope you enjoy them!

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: Understanding NVMe Support on Oracle Linux

Non-volatile memory express, also known as NVMe or NVM Express, is an interface specification that aims to enable a solid-state drive (SSD) to make the most effective use of the high-speed Peripheral Component Interconnect Express (PCIe) bus in a computer. 

NVMe has been supported in the mainline upstream release of Linux since kernel 3.3. Check out the commit log message for NVMe, and you can find pages of updates going back to 2011. The first distributions to support NVM Express focused on the add-in card form factor (without support for hot plug). 

Oracle was the first vendor to support NVMe hot-plug in a Linux distribution and today hot-plug is supported in all Oracle Linux releases beginning with Oracle Linux 6.4.

Oracle Linux NVMe Support *

Oracle Linux includes inbox support for NVMe SSDs beginning with Unbreakable Enterprise Kernel (UEK) Release 3 in October 2013. UEK R3 is supported in Oracle Linux 6.4 (or later) and Oracle Linux 7 (or later), and is enhanced to provide NVMe feature support consistent with mainline kernel 3.19, including hot-plug support (although without the block_mq feature).
