Have you ever wondered how to set up a cluster of thousands of nodes just in seconds, how to simulate real nodes with a low resource footprint, and how to test your Kubernetes controller at scale without spending much on infrastructure?

If you answered "yes" to any of these questions, then you might be interested in KWOK, a toolkit that enables you to create a cluster of thousands of nodes in seconds.

What is KWOK?

Author: Imran Noor Mohamed (Delivery Hero) Observability requires the right data at the right time for the right consumer (human or piece of software) to make the right decision.In the context of Kubernetes, having best practices for cluster observability across all Kubernetes components is crucial. SIG Instrumentation helps to address this issue by providing best practices and tools that all other SIGs use to instrument Kubernetes components-like the Api server, scheduler, kubelet and kube-controller-manager. In this SIG

Author: David Hadas (IBM Research Labs) This post warns Devops from a false sense of security.Following security best practices when developing and configuring microservices do not result in non-vulnerable microservices.The post shows that although all deployed microservices are vulnerable, there is much that can be done to ensure microservices are not exploited.It explains how analyzing the behavior of clients and services from a security standpoint, named here "Security-Behavior Analysis", can protect the deployed vulnerable microservices.It points to Guard, an open source
