A few years ago, we decided to address this complexity by spinning up a new initiative, and eventually a new team, to move the complex handling of user and device authentication, and various security protocols and tokens, to the edge of the network, managed by a set of centralized services, and a single team.

There was a time when standing up a website or application was simple and straightforward and not the complex networks they are today. Do you have a web server? Is the web server running? The last item to check was if the web server was able to talk to the database? The recipe was straightforward. Do you have a database?

This query is performed by a Domain Name Server (DNS server) or servers nearby that have been assigned responsibility for that hostname.
