Any real world Java project will likely use external dependencies. As we’ve seen over the last few years, it’s important to keep these dependencies up to date. We used to have to manually check for updates, but fortunately these days there are tools available that can help us with this. Because, let’s be honest, most developers don’t enjoy maintaining applications. …

Logs and traces generated by applications are valuable sources of information that can help detect issues and improve performance. However, they are often treated separately from other data, even though they are no different from the data an application works with. In this tutorial, we will explore a different approach: treating logs and traces as part of a scalable cloud …

Failover is an important feature of systems that rely on near-constant availability. In Hazelcast, a failover client automatically redirects its traffic to a secondary cluster when the client cannot connect to the primary cluster. Consider using a failover client with WAN replication as part of your disaster recovery strategy. In this tutorial, you’ll update the code in a Java client …
