SkyWalking has over 500 contributors based on GitHub repository statistics. This is a remarkable achievement for the whole diverse community.
Kubernetes is arguably the best environment for running microservices so far, but the experience of debugging microservices in a Kubernetes environment may not be as user-friendly. This article will show you how to debug microservices in Kubernetes, introduce common tools, and explain how the introduction of Istio impacts debugging microservices.
Discovery selectors were one of the new features introduced in Istio 1.10. Discovery selectors allow us to control which namespaces Istio control plane watches and sends configuration updates for. By default, the Istio control plane watches and processes updates for all Kubernetes resources in a cluster. Istio configures Envoy proxies in the mesh to reach every workload in the mesh and accept traffic on all ports associated with the workloads.
Istio was named by Tetrate founder Varun Talwar and Google lead engineer Louis Ryan in 2017 and was open sourced on May 24, 2017. Today is the fourth anniversary of Istio’s open source arrival. Let’s take a look back at Istio’s four years of development — and look forward to Istio’s future.
Years ago when I heard WebAssembly (Wasm) for the first time, I was intrigued. The fact that I can write code in Rust or C++ and have it running in a browser blew my mind immediately. Porting an existing browser-side computation from JS code to Rust results in an increased performance. Needless to say, I have high expectations from this technology. Sadly, due to personal circumstances, I haven’t had much time and opportunity to explore this technology further.
That is, until last week.
In light of the collaboration that marks the cloud native community’s approach to today’s distributed workplaces and environments, the title hashtag of KubeConEU 2021 was #TeamCloudNative. This year’s virtual conference brought together this massive community and included hundreds of sessions and 11 distinct Zero Day co-located events.
Enterprises are increasing their investments in digital transformation and in hiring the right talent to accelerate the journey. According to the 2020 open source jobs report from Linux Foundation, 52% of hiring managers are more likely to hire someone with a certification, up from 47% two years ago. Not so surprisingly, 93% of hiring managers report difficulty finding sufficient talent. Tetrate today announced the public availability of its exam for Certified Istio Administrator by Tetrate (CIAT) that evaluates skill, knowledge, and ability to perform Istio service mesh installation and configuration as well as configure traffic management, resilience and fault injection, and use security features of the Istio service mesh. This follows the February launch of the free training and certification course on Istio Fundamentals. Over 600 IT professionals have taken the training since then.
