1. MONOLITHS MUST DIE! A VERT.X TALE ON REACTIVE MICROSERVICES by / RedHat Principal So ware Engineer Paulo Lopes @jetdrone
2. CHAPTER 1 MONOLITHS APPLICATIONS ARE REAL
3. MSA KILLER APP The services are easy to replace Services are organized around capabilities Services can be polyglot Architectures are symmetrical rather than hierarchical
4. CHAPTER 2 SOLVING THE PROBLEM THE "STANDARD" WAY
5. APPLICATION CONTAINER
6. APPLICATION CONTAINER Security Threading Transaction Management Load balancing
7. CONTAINER API
8. PERFORMANCE Blocking Thread safety Locking C10K
9. SCALE Load balancer Sticky sessions Single point of failure
10. WHY CAN'T THIS SCALE?
11. CHAPTER 3 HELLO VERT.X

29. UNLIMITED HORIZONTAL SCALING
31. CHAPTER 5 MONOLITHS WATCH OUT!
32. MONOLITHS MORTAL WEAKNESS Message driven problem domain HTML5 and Realtime/Websocket problem Address services running on browsers Flexible actor model Scale out Mixed async and blocking code
33. NO COMPARISON
34. NOT DEAD YET
