There is so much quality information in this book that focus more on principals than technologies which mean although this book is without reference to some modern tools that assist in designing and developing micro or even nano service architectures - the information remains applicable and will continue to do so for years to come.
Well worth a read for anybody who is in the throws of a Microservice architecture or planning to embark on the journey.
The book covers the main problems of splitting services into smaller ones. The examples give a better idea about the problems and solutions. It has the right level of detail to point someone in the right direction.
