3. First Question: What is Spring?
   • Java
   • Libraries (modular)
   • Open source
   • “Enterprise” (data, integration, services etc.)
   • Boilerplate
   3
   If you write code that isn't making you money, then think again.

12. No Man (Microservice) is an Island
    It's excellent to be able to implement a microservice really easily
    (Spring Boot), but building a system that way surfaces
    "non-functional" requirements that you otherwise didn't have.
    There are laws of physics that make some problems unsolvable
    (consistency, latency), but brittleness and manageability can be
    addressed with generic, boiler plate patterns.

20. Spring IO Core: Reactor
    • Microservices proliferate in modern architectures
    • No Microservice is an Island
    • More Microservices === More Runtime Resources required
    • More More Runtime Resources required === More $$$
    • Microservices have acute need for efficiency
    • Contrary to myth: Runtime Resources aren’t free/cheap
    • Microservices are natural fit for Reactive Architecture
