The document discusses moving from a monolithic application architecture to a microservices architecture. It describes some of the problems with monolithic architectures like difficulty with team development, deployment, and maintenance. Microservices offer a solution by breaking the application into independent, self-contained services. The presentation then outlines how to implement microservices using Google App Engine, including its benefits like scalability and the ability to focus only on writing code. It provides examples of technologies used to build microservices like containers, continuous delivery tools, APIs, and programming frameworks.
