Agile practices and techniques like continuous delivery and evolutionary architecture are all about being able to react to changes rapidly. However, putting them into practice when you have a big legacy monolith application can be a difficult job. The industry has come out with different ideas to solve this problem; microservices, pushed by companies like Netflix and Amazon, are the latest solution.
Having an architecture based on services offers many advantages (like scalability and technical flexibility), but it comes with upfront costs and complexity that few companies are in a position to pay. Cassandra Shum and Dan Lockman explore the prerequisites for moving into a microservices architecture and provide tips on how to achieve them via engaging exercises.
Cassie was the North American Lead for Mobile Technologies for the past year and a half. Now she is leading a large enterprise retail client, based in New York.
For 8+ years at ThoughtWorks, she has primarily been leading and developing in a variety of mobile projects alongside a wide range of other technologies and architectures, including event driven systems and microservices.
She loves to grow organizations in their delivery practices and organizational structures, but also the new generation of technologists. Cassie is one of the leaders of the ThoughtWorks’ women’s group, and helps promote more female speakers in technology.
Daniel Lockman is a developer at ThoughtWorks. Daniel has spent the last five years honing his craft with a variety of development experiences, creating products internally as part of an IT organization, coaching, pairing with, and leading teams, and writing software for different enterprise clients. While experienced with many backend and frontend frameworks, recently, Daniel has been working with microservices and using Scala, evolving them to both integrate with and deprecate legacy applications. He has spent much of the last few years learning difficult lessons about strong test suites, writing testable code, and creating truly productive developer workflows that integrate early and often.
