The document discusses a microservices architecture that emphasizes rapid development. It notes that the architecture is culturally fast, with ship early and often approaches and fast deploys and rollbacks. It also discusses how the architecture flows with organizational structure, with many small independent services owned by different teams that can deploy independently. Examples of service sizes at a company range from tiny single page services to mega services with hundreds of thousands of lines of code and dozens of pages and APIs.
