Do You Really Need Kubernetes?

These days, it seems Kubernetes is a topic that is never too far from people's lips.  The tool, and the associated tools built around it, are talked about so often it seems it's the only subject important to developers these days - especially as the IT world becomes increasingly orientated towards cloud and microservices.

But in spite of all the conversation around Kubernetes... do you really need Kubernetes for your environment? Or is it just another case of the next 'new and shiny' object,  with people distracted by the novelty and possibility, rather than the facts? In this blog, I'll take a closer look at why Kubernetes might be a case of the hype outweighing the helpfulness in most cases.

Getting Started With Jakarta EE 9: Hello World

Introduction

The release of Jakarta EE 9, at the end of 2020, was in many ways a historic event. The Java Enterprise framework is already 20 years old, having its first release in 1999. It has changed names a few times but the main concepts of the first release can still be found in this new release. During all those years, it has adapted itself to keep it up to date but has always adhered to its main principle of stability and backward compatibility.

Regarding backward compatibility, this release was also historic as the namespaces changed (like package names that changed from 'javax' to 'jakarta'). The change is straightforward, no other changes are introduced between Jakarta EE 8 and EE 9.  This to make the migration as easy as possible.
