Microservices — the Letter and the Spirit
Microservices to be a pattern of ‘decoupled services’ managed to get the best out of it (the underlying understanding of the pattern (‘small’ vs ‘decoupled’) forces developers to take certain design decisions that are consistent with these objectives. In this article discuss we will discuss well and poor implementations: ‘small-services’ vs ‘decoupled-services’ or ‘Letter’ vs the ‘Spirit’.

Turning Microservices Inside-Out
Turning microservices inside-out means moving past a single, request/response API to designing microservices with an inbound API for queries and commands, an outbound APIs to emit events, and a meta API to describe them both. A database can be supplemented with Apache Kafka via a connecting tissue such as Debezium.

Keeping Technology Change Human
When we are at the forefront of so much change, it's easy to forget that other people around us find change more challenging. This article is a reminder to look beyond the code and processes, to consider how tech team actions can affect our users in emotional ways. It seeks to establish a few ways of thinking to help bring others along with us when working through technology change.

Using a DDD Approach for Validating Business Rules
If the goal is to create software applications that emulate the behavior of domain experts, then the challenge is in capturing and implementing the business rules. This is more a factor of good knowledge management than it is raw coding ability. Following techniques from Domain-Driven Design can provide a structure for effectively validating and implementing business rules in a system.
