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.
