Three years ago, I wrote an article titled "Back to Microservices with Istio" for Google Cloud - Community. I published it there to reach a reader base interested in the latest technologies built on top of Kubernetes. At that point, Istio was a niche technology.

I co-authored the book "Istio in Action" together with Christian Posta (@christianposta), which is recently published by Manning.

I joined Solo.io, where I collaborate daily with clients to best utilize the service mesh capabilities. Be it for improving resiliency, reducing the risk of shipping new software, improving the security posture, or any of the myriad capabilities it enables. Kubernetes, which even then was reaching wide adoption, has now become a mainstream global technology, and as the number of services operated on it increases — so will the number of organizations adopting Istio increase too.
Furtherly, Istio is not a niche technology anymore! After many improvements in the user experience — for example, installation and day-2 operations became way easier — Istio has been adopted by organizations of different sizes and industries. At the same time, it is continuously expanding its toolset further by adding support for virtual machines, making the mesh scale into multiple clusters, and much more.
The last thing you need to know is that the market lacks people with this kind of knowledge. We need you! That’s why I entirely rewrote this article to be a thorough introduction to Istio and show what it does under the hood because I don’t want you only to know "what" it does but as well "how" it does it.
