You have a monolith. The monolith is deployed by a grumpy old admin using a shell script. He monitors it with another shell script. This is the old, bad way of doing things. Monoliths are bad because they are the kind of thing only neolithic cavemen would care about. So you break up the monolith into micro-services. Of course, you use (other) services to provision and monitor your new micro-services. You now have dozens of tools and scripts and configuration files. This is, naturally, the modern way of doings things. If tomorrow morning, your 500 customers suddenly become 3 million customers, you can just flip a switch and scale on demand in the cloud! Soon you'll be so successful that you can even hire an entire team to look after your new non-monolithic system.
