With many illustrative examples, insightful migration patterns, and a bevy of practical advice to transition your monolith enterprise into a microservice operation, this practical guide covers multiple scenarios and strategies for a successful migration, from initial planning all the way through application and database decomposition. You'll learn several tried and tested patterns and techniques that you can use as you migrate your existing architecture.

A classic children's fairy tale retold with an anarchic and hilarious new spin for a new generation of readers.

Distributed systems have become more fine-grained in the past 10 years, shifting from code-heavy monolithic applications to smaller, self-contained microservices. But developing these systems brings its own set of headaches. With lots of examples and practical advice, the second edition of this practical book takes a holistic view of the topics that system architects and administrators must consider when building, managing, and evolving microservice architectures. Microservice technologies are moving quickly, and this revised edition gets you up to date with a new chapter on serverless and cloud-native applications, expanded coverage of user interfaces, more hands-on code examples, and other additions throughout the book. Author Sam Newman provides you with a firm grounding in the concepts while diving into current solutions for modeling, integrating, testing, deploying, and monitoring your own autonomous services. You'll follow a fictional company throughout the book to learn how building a microservice architecture affects a single domain.

Tipped off by a disgruntled local about the money to be made from a takeover of Wilberforce Original Brassworks, City speculator Mervyn Pusey decides to cast an eye over the sleepy family business in the heart of the Yorkshire Dales. As the board members turn to their London merchant bank for advice, their only slightly dotty personnel director continues to be more concerned about arrangements for the village show. While support from their London advisers lands them with the sarcastic behemoth Hugo Russell, whose entry to the village on the back of a tractor does little for his self-esteem, it also introduces them to Simon Beresford, guileless spin doctor, doting husband and welcome recruit to Bradburn's First XI. As each of Pusey's clandestine visits to Bradburn ends in ignominy, worse things befall his secret informant. Meanwhile, Splasher Shelmerdine's chimney cleaning challenge has mixed results, Miss Fitton's doily-napkins create a headache for Morris dancing academic Roger Spofforth, and it is left to the beautiful Julia Mowbray to beard decidedly potty Uncle Edwin whose shareholding could be the decisive factor in a battle the sets the guile of the City's money men against a family business with everything to lose.
