A look at the roles of architect and strategist, and how they help develop successful technology strategies for business. I should start by saying this section does not offer a treatise on how to do architecture. Technology systems are difficult to wrangle. Our systems grow in accidental complexity and complication over time.

Stream processing One approach to such a challenging scenario is stream processing, a computing paradigm and software architectural style for data-intensive software systems that emerged to cope with requirements for near real-time processing of massive amounts of data. This significantly increases event latency.

Most organisations go through an architecture modernisation effort at some point as their systems drift into a state of intolerable maintenance costs and they diverge too far from modern technological advances. This means a software architecture should be purposely designed for the most favourable business consequences.

The microservices era has been good for software architecture. A domain service builds on the basic definition of a microservice: it’s a loosely-coupled, independently deployable element of software architecture which is owned by a single team. I remember when the idea of multiple databases was punishable by death.
