This article discusses the differences and similarities between Modular Monolith and Upfront microservices for microservice architecture. Identifying (micro)service boundaries is a challenge and becomes relatively easy as we learn more about the business domain. So we wanted to try a modular monolith (modules within microservice) approach. As the module matures and we see it becoming first class microservice, we can take it out of the modular…

Hexagonal Architecture is defined by Alistair Cockburn @TotherAlistair Hexagonal Architecture is very relevant in Platform Thinking. Core System is designed with Domain Driven Design concepts like bounded context, context maps and Ubiquitous language. Core System sits at middle of hexagon. Microservices will be part of Core System. Any input or…

I have used clojure on some of projects in past. I have worked on Java, Ruby, C#, Nodejs projects in past and know fair bit of scala. As I use clojure on projects, I find it very useful language. Appropriate tools are very important to do a job right. This…

Aggregate is Domain Driven Design concept. Aggregate is cluster of object which is treated as one unit for purpose of state change. Invariants applied with Aggregate will be enforced with completion of each transaction. Event Sourcing Event Sourcing is an Architectural Pattern in which state of application is being determined…

You are good to write #microservices if you can write good monoliths! If you are starting on green field (new domain/ rewriting existing domain) project, it is better to start with monolith. Following are things which will be helpful for development team to keep in mind. Understand THE Domain. Talk…
