An Adventure in Multi-Cloud Networking with Kubernetes and Tungsten Fabric

With a couple weeks before KubeCon and an impending presentation, I embarked on a small adventure to try networking together two different Kubernetes clusters with Tungsten Fabric, the goal being to do a live demo at the Tungsten Fabric Developers Summit.

The demo was designed to be a simplified illustration of the broader hybrid/multi-cloud use case of connecting two distinct networks in t…

Comparing Service Meshes: Istio, Linkerd and Consul Connect

The use of microservice-based architectures has skyrocketed in the past few years, highlighting their ability to make applications more scalable, portable, and resilient than their monolithic predecessors. But the volatile and ephemeral environments that microservices encourage can make networking inherently problematic.

It can be difficult to establish trust between microservices, slowing…

Why Kubernetes Ingresses aren’t as Difficult as You Think

How to use Ingresses to Route your Services on a Vanilla K8s Deployment
If you’re using Kubernetes, you probably have deployments or stateful sets managing a number of pods that are running different microservices within a greater application. What use is this if your microservices can’t communicate with each other? They are running as a number of pods scheduled by Kubernetes, and these pods…

Java’s Got a New Release Train: Are you on it or under it?

Oracle is taking a more contemporary approach to releasing new versions of the Java platform with the recent release of Java 10. Rather than letting feature readiness drive the timing of new releases, Oracle will employ a train release model. New versions will be released every six months – regardless of content. Sun Microsystems, and now Oracle, have traditionally released new versions every two…

Solving Complexity at the Network Layer with Istio

Istio and the service mesh

Developed in collaboration between Google and IBM, Istio is an open source technology that provides operational control over and behavioural insight into the service mesh of an application as a whole. Sitting above the application layer, service meshes consist of a dedicated network layer abstracted away from microservices themselves. Monitoring the service mesh,…

Docker and Kubernetes: What is the Value of Containerization?

In the last few years, containerization and microservices-based architecture took the DevOps community by storm. According to 451 Research, container technology such as Docker and Kubernetes will see the fastest growth compared to other cloud-enabling technologies, with an estimated CAGR of 40% through 2020 (see Figure 1). “Two things stand out from our market sizing and research on…
