Architecture Weekly Issue #37. Articles, books, and playlists on architecture and related topics. Split by sections, highlighted with complexity: 🤟 means hardcore, 👷‍♂️ is technically applicable right away,  🍼 - introduction to the topic or an overview. Now in telegram as well.


It's already been 221 days since Russia's crazy, brutal, unjustified war against Ukraine. We condemn this war and want it to stop ASAP. We continue this newsletter so you can advance your skill and help the millions of Ukrainian people in any way possible.

Architecture for Flow with Wardley Mapping, DDD, and Team Topologies 👷‍♂️

With this talk I learned about Wardley Map - a tool to create the strategic design of an application or a service. Having introduced that, Susanne Kaiser shows how to apply it to online learning domain, add a bit of Domain-Driven Design, a grain of Team Topologies to come up with a well-though solution.

Smart Endpoints and Dumb Pipes 🍼

Moving from a monolith to microservices requires some mediator to facilitate the interaction between services. The choice you face is either to have some smart common bus which is basically an idea of Enterprise Service Bus or move the communication logic to the nodes themselves, and make the bus as dumb as possible. The article nicely explains the choice.

What Does ‘Smart Endpoints and Dumb Pipes’ Mean? | Nordic APIs |
“Smart endpoints and dumb pipes” sums up the theory around optimal inter-service communication for microservices architectures.


The right does of resilience 👷‍♂️

As with any Quality Attribute, resilience is usually achieved by applying the related tactics or calling them other way, patterns. You apply healthchecks here, circuit breakers there, add blue-green deployment etc. But the number of patterns is high, and if you apply all of them, you will overcomplicate your system. Uwe wrote an incredible post with resilience patterns and examples of subsets applied in different systems.

Adventures in Building Reliable Distributed Systems with Liquid Haskell 🤟

Distributed Systems have many problems like replication issues, consistency, strong convergence etc. Even if you find a solution, it is very hard to prove it's working. Lindsey Kuper gave a keynote on how Haskell can be used to build up a type system to verify the distributed systems properties. A hardcore butincredibly useful article with the transcription of the said talk below.

My FLOPS 2022 keynote talk: “Adventures in Building Reliable Distributed Systems with Liquid Haskell”
Back in May, I gave the opening keynote (my first keynote talk!) at the FLOPS 2022 conference. I talked about the work we’ve been doing in my group on using Liquid Haskell for verifying the correctness of distributed systems.
