When our software outputs JSON, it can be hard to test. Consider this code: 1 2 assertThat(someJson)    .isEqualTo(expectedJson); Assuming the rendering of the resulting json matches the spacing of the expected JSON, this will work. When it doesn’t work, we get a big old string diff result telling us that the strings were different. But JSON isn’t a String What ...

The previous article demonstrated how to implement cross-cluster Anthos Service Mesh (ASM) in a single network. In this article we will illustrate the mesh service communication using different VPC network. The use case will focus on setting up two GKE cluster with ASM installed in two different VPCs. As the clusters are in different networks, the services in a mesh ...

One of the advanced mesh constructs or topologies are multi mesh or cross mesh designs that aids in inter-cluster communication. With such a topology, each cluster will implement its own mesh runtime federating to form one logical mesh. You may setup mesh control plane in every cluster or you can have all the clusters communicate to one central mesh control ...

With time progressing, technology is transforming at a lightning speed to make the software development process much simpler, faster, qualitative and convenient. Technologies like machine learning and AI are being utilised in several ways, not only to process qualitative and faster data but also to process predictive data. Having said that, the software development lifecycle has also evolved extensively since ...

In our previous article from this series shared a look at the logical common architectural elements found in a cloud adoption solution for retail organisations. The process was laid out how we’ve approached the use case and how portfolio solutions are the base for researching a generic architecture.  It continued by laying out the process of how we’ve approached the use case by ...

In this post we will learn how we can use Kotlin extension functions to provide a simple and elegant type conversion mechanism. Maybe you have used Apache Sling before. In this case, you are probably familiar with Slings usage of adapters. We will implement a very similar approach in Kotlin. Creating an extension function With Kotlins extension functions we can ...

If you’ve worked with Go before, you’ve probably seen this runtime error. 1 panic: runtime error: invalid memory address or nil pointer dereference The current solution is checking thevar != nil before using the var, but forgetting to do that means your program will crash. That means this simple programmer error could take down your whole server. Hopefully you catch ...
