Samenvatting

Many organizations today orchestrate and maintain apps that rely on other people's services. Software designers, developers, and architects in those companies often work to coordinate and maintain apps based on existing microservices, including third-party services that run outside their ecosystem. This cookbook provides proven recipes to help you get those many disparate parts to work together in your network.

Author Mike Amundsen provides step-by-step solutions for finding, connecting, and maintaining applications designed and built by people outside the organization. Whether you're working on human-centric mobile apps or creating high-powered machine-to-machine solutions, this guide shows you the rules, routines, commands, and protocols—the glue—that integrates individual microservices so they can function together in a safe, scalable, and reliable way.

- Design and build individual microservices that can successfully interact on the open web
- Increase interoperability by designing services that share a common understanding
- Build client applications that can adapt to evolving services without breaking
- Create resilient and reliable microservices that support peer-to-peer interactions on the web
- Use web-based service registries to support runtime "find-and-bind" operations that manage external dependencies in real time
- Implement stable workflows to accomplish complex, multiservice tasks consistently

Over Mike Amundsen

An internationally known author and lecturer, Mike Amundsen travels throughout the United States and Europe consulting and speaking on a wide range of topics including distributed network architecture, Web application development, Cloud computing, and other subjects. His recent work focuses on the role hypermedia plays in creating and maintaining applications that can successsfully evolve over time. He has more than a dozen books to his credit. His most recent book is "Building Hypermedia APIs with HTML5 and Node" He also contributed to the book "RESTful Web Services Cookbook" (by Subbu Allamaraju). When he is not working, Mike enjoys spending time with his family in Kentucky, USA
