Application programming interfaces (APIs) have become a critical part of networking, programs, applications, devices, and nearly everything else in the computing landscape. This is especially true for cloud and mobile computing, neither of which could probably exist in its current form without APIs holding everything together or managing much of backend functionality.
Because of their reliability and simplicity, APIs have become ubiquitous across the computing landscape. Most organizations probably don’t even know how many APIs are operating within their networks, especially within their clouds. There are likely thousands APIs working within larger companies and even smaller organizations probably rely on more APIs than they realize.
