Chapter 10. Architecting a microservice hybrid
This chapter covers
- Running the Cayambe monolith
- Integrating microservices into Cayambe with a hybrid approach
- Modifying Cayambe to integrate your microservices
- Running the integrated Cayambe in a hybrid cloud
This chapter starts by showing you the old Cayambe and how to get it running locally. Then, after covering some theory on using the hybrid approach to integrating your microservices, you’ll revisit the architecture you’re looking to achieve for the new Cayambe. Next, you’ll dive into implementing the hybrid approach, with the microservices you’ve developed throughout the book so far. Finally, you’ll take your revitalized Cayambe monolith, along with the required microservices, and get them all running in the cloud.
