Platform engineering is the discipline of designing and building toolchains and workflows that enable self-service capabilities for software engineering organizations in the cloud-native era.

Platform Engineering

Yes. People always look at my huge bookshelf when I take calls from home. But it's MUCH smaller because so many books went to the garbage bin. A lot of my technical knowledge on huge subjects (OpenDOC anyone?) is no longer applicable.

But a lot of the technologies come back with a different implementation. CORBA might be relevant only in legacy systems today but the core concepts of interoperable objects and distributed computing haven't changed fundamentally. We're still solving over and over again the same set of problems that we solved in the 60s. A lot has changed but a remarkable amount of stuff is similar.
