When I moved into an apartment, I didn’t build scaffolding around the building to support a rope and pulley system to lift boxes of my furniture and belongings to the 19th floor. My stuff was put into an elevator with a dedicated shaft, supported by specifically designed mechanical infrastructure and a simple computer system. The latter way is much safer, more effective, and automated.
In my last post, I wrote about how many DevOps practitioners are still manually generating and managing their machine identities, especially TLS certificates. Think about all of the load balancers, servers, containers, virtual machines, and other network entities that are constantly launched and killed within a DevOps environment. They all need machine identities, yet some of those entities have lifespans of only a few hours.
