Perspective on Architectural Fitness of Microservices
In this article we peel the onion of potential architectural fitness of microservices in the context of Master Data Management, and the challenges a microservices-based architecture may face when solving problem domains that require compute-intensive tasks, such as the calculation of expected losses on a portfolio of unsecured consumer credit.

Self Contained Systems (SCS): Microservices Done Right
Everybody seems to be building microservices these days. There are many different ways to split a system into microservices, and there appears to be little agreement about what microservices actually are - except for the fact that they can be deployed independently. Self-contained Systems are one approach that has been used by a large number of projects.

Developing Transactional Microservices Using Aggregates, Event Sourcing and CQRS - Part 1
Developing transactional business applications using the microservice architecture is challenging, because domain models, transactions and queries are resistant to functional decomposition. This article describes a way to develop microservices that solves these problems by using Domain Driven Design, Event Sourcing and Command Query Responsibility Segregation (CQRS).
