Mutation Testing with Java

How well tested is your system? How do you measure it? Code coverage can give you the answer, however, can we trust our unit tests? Trust me or not, but...

Architectural Caching Patterns for Kubernetes

Kubernetes brings new ideas of how to organize the caching layer for your applications. You can still use the old-but-good client-server topology, but now there is much more than that....

Build Your Kubernetes Operator with the Right Tool!

You want to build a Kubernetes Operator for your software. Which tool to choose? Operator SDK with Helm, Ansible, or Go? Or maybe start from scratch with Python, Java, or...

Distributed Locking and Java

Some say that there is no such thing as “distributed lock”. Still, sooner or later, you’d encounter a problem that only one of your application replicas may execute the given...

5 Levels of High Availability: from Multi-instance to Hybrid Cloud

Does running your application on multiple machines mean it’s highly available? Technically yes, but the term HA is already more than that. Take Kubernetes installation, if you install it on...
