Leveraging Hexagonal Architecture We needed to support the ability to swap data sources without impacting business logic , so we knew we needed to keep them decoupled. We decided to build our app based on principles behind Hexagonal Architecture and Uncle Bob’s Clean Architecture. MORE
Having just concluded participation in another In-Memory Computing Summit , it has become even more clear to me that the key to mainstream adoption of in-memory computing software platforms is architecture — the root of a platform’s value to applications. This notion has been reinforced through four decades of work in computer architecture and software after it was first driven home to me by a luminary in computer architecture at Intel Corporation, the late George Cox.

Organisations maximising the advantages provided by microservices tend to be organisations which view microservices not just as a technical tool, but a sociotechnical tool.The way software systems are shaped determines the communication paths and the coupling between development teams.

domain-driven-design software-architecture domain-modelingHow do we break a large system into smaller, more manageable modular components? This is the question I get asked the most, so I’ve put together this article describing a workshop recipe you can use.

There is no shortcut to identifying good boundaries. MORE
