restQL, a Microservices Query Language, Released on GitHub
restQL, a query language for microservices, is now available as an open-source project on GitHub. The restQL language is intended to simplify common scenarios for client-side access to RESTful microservices, including multiple parallel calls and chained calls. restQL was created to avoid some limitations of the more well-known data querying and management frameworks Falcor and GraphQL.

Entity Services is an Antipattern
In a microservice based architecture, it is important to keep the different services separated. Entity services is a common pattern now applied to microservices, but Michael Nygard claims that entity services is an anti-pattern that works against separation.

How Technical Practices Support Evolutionary Architecture and Continuous Delivery
Technical practices of XP such as TDD, Refactoring, CI and Pair Programming support emergent design and enable evolving your architecture. The first practice you need for continuous delivery is CI, committing to mainline every day. Being able to write clean, well-factored, and well-tested modular code is the most important skill for developers.

Event Sourcing in an Unreliable World
Examples of event sourced systems are often from process-oriented domains, like e-commerce, with incoming commands that generate events. But there are domains without processes that are intrinsically unreliable where we are collecting events from external event sources with transports that are unreliable, Lorenzo Nicora explained at the recent Microservices Conference µCon London 2017.
