Friday Spotlight: Video - Deploying and Upgrading OpenStack with Docker

OpenStack is notoriously complex to deploy and update. Traditional method of using RPMs is extremely unreliable due to inter-dependencies resulting into delays in deployment and failures in update. Any change in any of the RPMs may can adversely impact other RPMs and the deployment risks failures and delays.

Leveraging OpenStack upstream Kolla project, Oracle has transformed the deployment. OpenStack services are deployed as micro-services in docker containers which are fully independent from each other. Using the Ansible deployment tool, any of the containers can be changed or replaced easily without impacting other containers.

In this video during OpenStack Day in Australia, Avi Miller, Oracle Product Management Director covers the details of the ACTUAL EXPERIENCE with Oracle OpenStack distribution using Docker containers

Watch this great video for insight into OpenStack implementation.

    FRIDAY SPOTLIGHT: Announcing Oracle OpenStack for Oracle Linux 2.1

    Happy Friday everyone!

    Oracle OpenStack for Oracle Linux Release 2 (Kilo) uses Docker Containers for simplified, fast and reliable deployment. Today Oracle announced the first update release (2.1). This release delivers several new features and enhancements engineered for a modern cloud infrastructure, including: 

    Support for:  
    • Oracle VM Server 3.4.1 hypervisor: supporting Unbreakable Enterprise Kernel (UEK) Release 4 and Xen hypervisor version 4. 
    • Ceilometer Telemetry Service: to collect, normalize and transform data produced by OpenStack services for various telemetry use cases such as metering, monitoring and alarming. 
    Enhancements to:

    • Cinder Block Storage Service: iSCSI ZFS driver for Cinder services and iSCSI multi-path to Cinder volumes
    • Updating Services: new kollacli upgrade command to deploy updates to ALL hosts. 
    • Backup and Restore: OpenStack data is now stored directly on the host rather than on a dedicated Docker volume container. The required directories in /var/lib/kolla are created automatically on deployment of the Release 2.1.
    • Performance and Scalability: ability to deploy Heat and Murano services to a custom standalone group (previously these could be deployed only on the controller node).
    • Configuration Set-up: automatic hypervisor detection and automatic configuration of nova compute node.
    • Configuration Flexibility: enabling group-specific and host-specific Kollacli properties.

    FRIDAY SPOTLIGHT: What is on tap for Linux Container strategy in 2016?

    Happy Friday to all our blog readers!

    This week we would like to draw your attention to an insightful article written by By Robert Shimp, Product Management Group VP, Oracle Linux and Virtualization, published in NetworkWorld on May 3, 2016.

    What’s on tap for Linux container technology in 2016 

    By Robert Shimp, Product Management Group VP, Oracle Linux and Virtualization 

    Network World | May 3, 2016 12:12 PM PT

    Some debates remain, including what operating system will run under container applications 

    "White hot interest in containers has been driven by cloud computing’s demand to simplify deployment, streamline time to production, and automatically deliver the resources an application needs. Linux containers provide that in a nice package: a simple tool for developing, testing and delivering an application to the end user.

    Containers are designed to make it easier and quicker for developers to create complete application operating environments. Gone is the painful validation process of traditional application deployments that require developers to identify the minimum system requirements needed to run the application. ..."

    There are other important benefits. Linux containers package just about any type of server application to run everywhere – on your desktop, in a cloud, or anywhere Linux is available – regardless of kernel version or Linux distribution. Containers also can have a considerably smaller footprint than VMs, which means your systems can see higher densities and run more cost effectively with containers than with VMs on the same host.

    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:

    • Live Virtual Event: Attend a live event from your own desk, no travel required. Choose from a selection of events on the schedule to suit different timezones. Events on the schedule include 25 and 31 January, 8 February, 13 March, 24 April, and 17 July 2016.

    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.

    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!
