In this article, I’ll give you an overview of Istio‘s history of virtual machine integration support. In particular, the introduction of the smart DNS proxy and WorkloadGroup in Istio 1.8, which makes virtual machines and containers equivalent at the resource abstraction level.
Envoy Proxy has announced the release of 1.17. The new version released on Jan. 11, 2021 brought a breaking change: v2 API is deprecated.
The observability problem for modern DevOps is familiar: As enterprises move to microservices, containerization, multi-language RPC frameworks, and service meshes, there’s an increasing need for users to understand a highly complex, distributed architecture and the dependencies between applications. Apache SkyWalking, an application performance monitor (APM) and observability platform, is an open source project that addresses this need — with or without a service mesh.
You may have heard that DNS functionality was added in Istio 1.8, but you might not have thought about the impact it has. It solves some key issues that exist within Istio and allows you to expand your mesh architecture to include multiple clusters and virtual machines. An excellent explanation of the features can be found on the Istio website. In short, it enables seamless integration across multiple clusters and Virtual Machines. In this article, we’ll test out the new features and hopefully explain more about what is happening under the hood.
To give you the latest on the Istio service mesh, Tetrate hosted a live Ask Me Anything about Istio webinar on Dec. 16, 2021, with Istio engineers Zack Butcher, Weston Carlson, and Vikas Choudhary; Zack Butcher is an Istio contributor and member of its steering committee. These were our top takeaways.
Service mesh architecture provides a rich set of features for controlling and securing communications among services. Encryption in transit is a feature that will be critical for financial institutions and other industries working within regulatory frameworks, including PCI, HIPAA, and others.
1.8 is the last version of Istio to be released in 2020, it keeps following the trade winds and listen to the users’ feedback, which has the following major updates:

One of Envoy’s many powers is traffic routing and load balancing. For any dynamic environment that’s subject to regular changes, it needs a dynamic configuration mechanism that is capable of enabling users to make those changes easily, and most importantly, with no downtime.
