Increasing Security with a Service Mesh: Christian Posta Explores the Capabilities of Istio
Istio attempts to solve some particularly difficult challenges when running applications in a cloud platform: application networking, reliability, and observability and (the focus of this article) security. With Istio, communication between services in the mesh is secure and encrypted by default. Istio can also help with "origin" or "end-user" JWT identity token verification.

Envoy Service Mesh Case Study: Mitigating Cascading Failure at Lyft
Over the past four years, Lyft has transitioned from a monolithic architecture to hundreds of microservices. As the number of microservices grew, so did the number of outages due to cascading failure or accidental internal denial of service. Today, these failure scenarios are largely a solved problem within the Lyft infrastructure due to the use of the Envoy Proxy as a service mesh.

Q&A on the Book "Microservices, a Practical Guide, Principles, Concepts, and Recipes"
The book “Microservices, a Practical Guide, Principles, Concepts and Recipes” by Eberhard Wolff explores technology stacks for microservices-based architectures that can be used on the implementation decisions at the overall system level. Targeted to architects, developers and operations, it provides a set of recipes along with executable samples that can be used to address different needs.

How Contract Tests Improve the Quality of Your Distributed Systems
Catching bugs at the end of a development cycle is costly, but how do you incrementally test complex distributed systems? In this article, Marcin Grzejszczak looks at an integration testing approach for communication between components. He reviews contract testing, and Spring Cloud Contract, as one solution.

Measuring Tech Performance: You’re Probably Doing It Wrong
We try our best to measure our performance, and along the way identify just the right OKRs and KPIs and ABCs. There’s no One True Metric That Matters, but there are some useful guidelines and some all-too-commonly made mistakes. Use measures that focus on outcomes, not output, and measures that optimize for global or team outcomes, not local or individual outcomes.

Securing web.config with Encryption Certificates on Windows and Azure
A major area where security is often lax is the web.config file. Usually stored in plain text, an intruder who gains access to this file can then easily access databases and other resources both internal and external. With this technique, secrets in your web.config can be encrypted using the Windows certificate store
