In this post we introduce the basics of reading and writing Apache Spark DataFrames to an SQL database, using Apache Spark's JDBC API. Apache Spark’s Structured Streaming data model is a framework for federating data from heterogeneous sources. Structured Streaming...
Managing disaster recovery with GitOps and Ceph RBD mirroring
In our previous blog, Managing application and data portability at scale with Rook-Ceph, we talked about some key features of Rook-Ceph mirroring and laid groundwork for future use case solutions and automation that could be enabled from this technology. This post...
Deploying a full-service 5G network on OpenShift
During the last Kubecon North America in San Diego, a cross-vendor team of engineers from Red Hat and several other companies rolled a half-rack of servers and a self-made Faraday cage onto the keynote stage and demoed live a full 5G/4G network connected to two...
Using machine learning and analytics to help developers
It was the talk title that caught my eye - “Developer Insights: ML and Analytics on src/”. I was intrigued. I had a few ideas of how machine learning techniques could be used on source code, but I was curious to see what the state of the art looked like now. I...
Size matters: how Fedora approaches minimization
As part of a modern IT environment, Linux distributions can look to optimizing their size to be better suited for container use. One of the ways this improvement can happen is through reducing the size of a distribution, a process known as minimization. A new tool is...
Managing application and data portability at scale with Rook-Ceph
One of the key requirements for Kubernetes in multi-cluster environments is the ability to migrate an application with all of its dependencies and resources from one cluster to another cluster. Application portability gives application owners and administrators the...
