Re-imagining your legacy monolithic applications as microservices is a great opportunity to challenge design decisions such as choice of language, synchronicity, access patterns and coupling and promotes isolated deployments, modularity and separation of concerns, while providing per-end point analytics for free. See how Amazon API Gateway and Amazon Web Services Lambda, together with microframeworks like Chalice make "Peeling the Onion" and redefining legacy applications in terms of microservices manageable.

22. “From a business point of view,
we can replicate our entire
current stack for a fraction of cost
by leveraging as many AWS
services as we can.
By taking a serverless-first
approach, we get the added
benefit of increased uptime,
higher availability and elastic
performance. It's a win-win.”
