Modernizing the Monolith - Best Practices
In Chapter 7, we explored monolithic architectures and contrasted them with microservices-based architectures. We discovered that they are very different in their approach to interprocess communication, especially when it comes to database access. As a reminder, in monolithic architectures, it is quite common to have one or a few databases with many different applications or services from different business units accessing them. In microservices-based architectures, we want to have every service leverage its own database. So, in theory, in a microservices architecture, there is a database for every service we implement.
In this chapter, we will introduce some approaches for modernizing these legacy monolithic applications. We will also look at the best practices to keep in mind on your legacy modernization journey.
We will cover the following topics in this chapter:
- Understanding how we got here – the evolution of application...
