Microservices Premium

by Mark Little on  May 24, 2015 1

In a recent article Martin Fowler tries to answer the question about when to consider using microservices, hoping that developers understand that there is an inherent complexity involved in making such an architectural change. Sometimes staying with a well-designed monolith may be more appropriate.

Developing Provably-Correct Software Using Formal Methods

by Ben Linders on  May 22, 2015

Computer-checked models can be used to prove that core communications and state management in a software program are 100% logically correct. Such models can also be used to generate 100% correct source code. The usage of formal methods can reduce costs and time to market and help to deliver highly reliable software products.

Advantages of CQRS

by Jan Stenberg on  May 06, 2015

Domain-Driven Design the Wrong Way

by Jan Stenberg on  Apr 26, 2015 2

Applications claimed to have been built using Domain-Driven Design (DDD) in reality often consists of entities or DTOs separating data and logic together with services containing a mix of business and infrastructure logic, Gabriel Schenker states, noting that this also often applies early on to projects building new applications. Lack of knowledge is one major reason for this, Schenker believes.
