Discussion on: Architecture for Everyone

From the original post:

"Microservice architectures are just the “third wave” of Service Oriented Design."

Though where we differ in opinion is that those "minor things" the actual cloud architecture patterns, are things that provide the resilient capabilities of decent Microservice architectures.

You don't have to take my word for it though - docs.microsoft.com/en-us/azure/arc... Microsoft P&P has a great rundown of why they're so important.

"properly designed SOA system is indistinguishable from properly designed microservices" - I totally disagree with this statement though - 1st Gen "Traditional" SOA was all about n-tier architecture - Microservices archtectures tend towards consteallations of co-operating bounded contexts. It's a different topology, and the interactions between the services are different.

Ian Cooper does a great overview of the history and contrast between the two here - youtube.com/watch?v=Z9NtB7JMquY

I think if the whole world describes microservices, and SOA, as an architectural style, pedantically sitting at the "it's not an architecture!" end of the spectrum isn't going to convince anyone.

Thanks for engaging 🖤

I really impressed with a number of sources you're providing to prove your point of view. Unfortunately none of them explain how it is possible to have same application built as monolith and as microservices without any changes in architecture.

As for "cloud architecture patterns": they unavoidable once you switch to distributed system and let services communicate directly via unreliable channels. These patterns are not specific to microservices and often used without them. Moreover, resilience and other cloud-specific properties are achieved by means external to application and application architecture (various deployment/orchestration platforms, cloud services, etc.)

While talking/reading about microservices I often have feeling that a lot of things from different levels/layers are mixed into one big ball of mud and then declared as "advantages of the microservices architecture".

I feel like you're conflating software architecture and systems architecture here to be honest.

Well, it's not me, but proponents of "microservices architecture".

Sorry, don't want to look rude. Just too tired with microservices histeria which often causes so much harm although creates a lot of jobs for devops.
