Understanding gaps in the BrownField PSS microservices

In Chapter 7, Scale Microservices with Spring Cloud Components, the BrownField PSS microservices were developed using Spring Boot and Spring Cloud. Those microservices are deployed as versioned fat jar files on bare metals, specifically on a local development machine. In Chapter 8, Logging and Monitoring Microservices, challenges around logging and monitoring were addressed using centralized logging and monitoring solutions.

This is good enough for most implementations. However, there are still a few gaps in our BrownField PSS implementation. So far, the implementation has not used any cloud infrastructure. Dedicated machines, as in the traditional monolithic application deployments, are not the best solution for deploying microservices. Automation such as automatic provisioning, the ability to scale on demand, self service, and payment based on usage are essential capabilities required to manage large-scale microservice deployments efficiently...
