Chapter Overview

Most new companies today run their business processes in the cloud. Newer startups and enterprises which realized early enough the direction technology was headed developed their applications for the cloud.

Not all companies were so fortunate. Some built their success decades ago on top of legacy technologies - monolithic applications with all components tightly coupled and almost impossible to separate, a nightmare to manage and deployed on super expensive hardware.

If working for an organization which refers to their main business application “the black box”, where nobody knows what happens inside and most logic was never documented, leaving everyone clueless as to what and how things happen from the moment a request enters the application until a response comes out, and you are tasked to convert this business application into a cloud-ready set of applications, then you may be in for a very long and bumpy ride.
