Simple tasks like load balancing are very different in a realm where infrastructure is 100% ephemeral and often moving constantly — both in terms of setting up new instances with fresh IP addresses and geographically moving around the globe.

These new traffic management concepts and tools have the power to vastly improve developer experience and accelerate app development and delivery cycles through greater resilience, higher performance, and better secu …
