Granularity & Communication for Microservice Architectures
Architects struggle in modern distributed architectures with two Hard Parts: finding the appropriate service granularity and determining the correct communication styles between services. This talk introduces a new technique for performing tradeoff analysis for microservices architectures around both static and dynamic coupling. Static coupling helps determine the proper granularity by applying integrators and disintegrators. Dynamic coupling helps architects understand the interplay between communication (synchronous versus asynchronous), consistency (atomic versus eventual), and coordination (orchestration versus choreography), along with guidelines on when to choose particular communication styles. In this talk, Neal provides architects with the nomenclature and patterns to understand these difficult aspects of microservices and related architectures.

Oct 5 2023How to do distributed locking
As part of the research for my book, I came across an algorithm called Redlock on the Redis website. The algorithm claims to implement fault-tolerant distributed locks (or rather, leases [1]) on top of Redis, and the page asks for feedback from people who are into distributed systems. The algorithm instinctively set off some alarm bells in the back of my mind, so I spent a bit of time thinking about it and writing up these notes.
