How to Choose a Stream Processor for Your App
Choosing a stream processor for your app can be challenging with many options to choose from. The best choice depends on individual use cases. In this article, the authors discuss a stream processor reference architecture, key features required by most streaming applications and optional features that can be selected based on specific use cases.

Microservices from a Startup Perspective
When starting a journey to microservices, knowing what to consider might be overwhelming. No golden rule that is easily applicable exists. Every journey is different, since every organization is facing different circumstances. In this article I am sharing some lessons learned and challenges from a startup perspective, and what I would do differently the next time introducing microservices.

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.

PSD2: Blessing or Curse for Banks?
PSD2 will force all European banks to offer three APIs (Accounts, Transactions and Payments) free of charges to all 3rd parties approved by the ECB. This will allow new players to bring new and innovative products to the financial sector. For a successful transformation into a digital company, banks must evolve on three axis: Culture & People, Technology & Skills and Technical debt management.

Improving Testability of Java Microservices with Container Orchestration and a Service Mesh
In enterprise test scenarios, software needs to be tested in the same way as it will run in production. This article provides a practical demonstration of testing Java microservices that are running on Kubernetes with the Istio service mesh. K8s service abstractions enable mocking, and Istio enables us to re-route traffic and inject faulty responses or delays to verify our services' resiliency.

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.

Packaging Applications for Docker and Kubernetes: Metaparticle vs Pulumi vs Ballerina
Metaparticle, Ballerina, and Pulumi have introduced different approaches by empowering developers to handle deployment automation within programing language itself without having handwriting YAMLs. This is becoming a trend and will change the DevOps practice in the software industry.
