There are three types of companies in software architecture: those that are content with their monolith applications, those that plan to switch to microservices, and those that already use microservices in production. Each company has its reasons for choosing a particular architecture, but using microservices comes with its own set of challenges. For instance, when you decide to break down a monolith application into services, you need to figure out how to manage communication between the services.
In part 1, we will first look at the big picture of an e-commerce application, and then delve into microservices architecture and its critical requirements, such as fault tolerance, security, continuous integration/continuous deployment (CI/CD), public access, and scaling, among others. Proper communication patterns between microservices are essential, and we will cover this topic as well.
