What is Integration?
Integration, specifically in the IT realm, is the process of bringing together two or more IT systems to work together as a single system. It can be done at different levels, from integrating one system with another to integrating multiple systems across multiple departments, and it's essential for many companies' success.
As IT systems developed over time, it became common to have multiple solutions from multiple vendors that did not communicate with each other. Integration became a necessity when siloed tech stacks started negatively impacting business.
