Welcome to the musings of Stephen Brewin.

Here you will find my reflections on software architecture, development and operations.

Recent Musings

Microservice Musings : Overview

For those less familiar with microservice architectures, this overview briefly describes some key concepts…

Microservice Musings : Service Time

A microservice architecture encourages granularity which results in the invocation of significantly more services via network connections than more monolithic architectures…

Microservice Musings : Transactions

Legacy architectures usually use an ACID distributed transaction strategy. This has served well for many years but performs poorly in the highly-distributed environments that are typical of a microservice architecture…

Microservice Musings : Databases

Most microservice applications depend on a DBMS (Database Management System) for persistence. Greater DBMS performance is achieved by scaling vertically or horizontally to create a DDBMS (Distributed DBMS)…

Serverless Computing Musings : Overview

Cloud environments such as AWS Lambda, Google Cloud Functions and Microsoft Azure Functions support serverless computing. Stateless functions declare their required compute resources which the runtime provisions when the function is invoked removing the need for dedicated servers, hence the term serverless…
