Training Thursdays: Firewall Services in Oracle Linux Training

The default firewall service in Oracle Linux 7 is firewalld. In previous versions of Linux, you use iptables. firewalld offers several advantages over iptables:
  • Changes do not require restart of the firewalld service.
  • Networks can be separated into different zones based on the level of trust.

Firewall services is one of the many topics covered in Oracle's Linux system administration training. You can learn about firewalld and many other topics by taking the Oracle Linux 7: System Administration course. This course is available as a:

  • Training-on-Demand: Start training within 24 hours of registration, following lectures at your own pace through streaming video and booking time to perform hands-on exercises when suits your schedule.

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: Oracle Linux 6.8 is now available

On Monday evening, we released Oracle Linux 6.8 to the Unbreakable Linux Network.  This release is the first ISO to incorporate Unbreakable Enterprise Kernel Release 4 (Quarterly Update 1) and includes several improvements and features.  You can download this update from yum.oracle.com or from the Oracle Software Delivery Cloud.  For more information regarding the release or for details on how to update your system, please review the release notes located here.

 This is a great time to remind users of the channel features available with Unbreakable Linux Network (ULN).  Here are a few tips:

  1. If you are subscribed to the _LATEST channel, you will receive all the latest updates, including update releases like Oracle Linux 6.8.  This ensures your system is always up to date with not only the latest update release but also critical bug and security errata.
  2. For more control over patches and updates, you can also subscribe to the _BASE and _PATCH channel for your respective release.  These channel stays locked to a given minor release.  For example, if you have standardized on Oracle Linux 6.7 across your data center and only want updates released during the 6.7 maintenance window - subscribe to these channels.  Once you are ready to move to Oracle Linux 6.8, simply subscribe to the 6.8 _BASE & _PATCH channels.  Keep in mind, once a later update release is available, all errata updates will move to the latest channel.  It is always recommended users stay up to date on errata to ensure systems remain secure.  For more information about ULN please refer to the ULN User Guide.
  3. Finally, remember if you are an Oracle Linux Premier Support customer you also have access to zero-downtime patching with Ksplice.  For more information, please review the Ksplice User guide.

Please send us your comments and feedback.

    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.
