First off, AWS Lambda is a stunning programming model. A cross between stateless distributed functional programming at scale (say that fast ten times if you dare) coupled with zero-administration requirements. In other words, you write a function and AWS Lambda runs it at the appropriate scale for you.
What’s more is that, AWS Lambda can react to events following the event sourcing pattern. So you don’t keep any internal state, AWS Lambda executes your function with the event data.
Our job, as software developer, has just become almost too simple. The good news is that we can now focus on the value we are aiming for rather than the plumbing and machinery underneath. A whole new world.
