Chapter 6
Microservices Evolution - A Case Study
Section 1
Lesson Overview
This lesson will introduce BrownField Airline (BF), a fictitious budget airline, and their journey from a monolithic Passenger Sales and Service (PSS) application to a next generation microservices architecture. Also, this lesson examines the PSS application in detail, and explains the challenges, approach, and transformation steps of a monolithic system to a microservices-based architecture, adhering to the principles and practices that were explained in the previous lesson. The intention of this case study is to get us as close as possible to a live scenario so that the architecture concepts can be set in stone. At the end of this lesson, we will also examine a maturity model for microservice adoption. It will cover the objectives and topics that will be explained.
