If you’re developing a Java application, you’re likely using an APM, an exception management tool or a tracing solution. For any of those tools, you have probably faced the common challenge of monitoring a Java application: installing an instrumentation Agent. Java monitoring is performed by instrumentation agents called Java Agents and VM Agents. Both of…

By making it easier than ever to add powerful new microservices, Kubernetes has become a driving force behind companies breaking up monolith apps and transforming them into microservice architectures. But as their numbers grow, the cost of managing microservices and the dependencies between them increase exponentially as well. This makes things more complicated than many…

The weather outside is not yet frightful, but it’s getting cold in the codebase! As winter descends and temperatures plunge, many software companies implement a Holiday code freeze over the holiday period. The theory makes sense. New code means new and enhanced features, but also the risk of serious new bugs. The period from Halloween…

When developing software, debugging is essential. But users named debugging functions as the most common challenges associated with serverless architectures. Recently, several solutions have been introduced that claim to make debugging serverless functions easier (or just plain possible).
