Bridging Traditional and Modern Workloads

So many organizations find themselves straddling two worlds, the older ‘brownfield’ setup of Virtual Machines (VMs) and bare metal servers, and the ‘greenfield’ world of containers managed by Kubernetes. Managing a hybrid structure of these two types of infrastructures has a history of being time-consuming and complex, with an overburden on engineering to duplicate efforts. 

The addition of a service mesh to any environment that straddles ‘old’ and ‘new’ allows you to abstract away from disparate infrastructures and refocus your organization to being an application-centric entity.

Istio 1.6 release brings upgrades and new features

Istio’s 1.6 release brings improvements to existing features and new features that will make things easier for developers. Upgrades to 1.6 will also be a jumping off point for even more significant improvements to come: for managing hybrid services, and integrating VM and bare metal into the Istio mesh. A VM-friendly definition of a service will allow you to migrate VM workloads to a Kubernetes cluster without disrupting traffic flow.

How to debug your Istio networking configuration

These are the set of steps I walk through any time I sit down to debug an Istio setup, regardless of how much experience I have with the deployment. Most Istio errors in my experience are simple, “stupid” mistakes; having a checklist to walkthrough helps me catch problems a lot more quickly. With that said, these are the steps I generally walk through:
