Micro services may not be the best idea

1. SAMUEL ROZE MICRO-SERVICES  (MAYBE NOT)  A GREAT IDEA

2. 2 WHY THIS TALK?I SPENT A FEW YEARS BUILDING MICRO-SERVICES BASED APPLICATIONS Samuel Roze PHP Software Engineering background and consultancy. Worked with microservices architectures and containers to help development teams' velocity. ContinuousPipe.io Continuous deployment pipeline for containerised applications. Kubernetes- powered PaaS. Increase your development team velocity and the collaboration between the technical and business project members.

16. 6 CONSEQUENCESOF SUCH A COMPLEX INFRASTRUCTURE OPS COSTS ON-BOARDING SPEED had to manage multiples instances of databases, queues and cache "How can I run the platform on my laptop?"

17. 6 CONSEQUENCESOF SUCH A COMPLEX INFRASTRUCTURE OPS COSTS CHANGE  COMPLEXITYON-BOARDING SPEED had to manage multiples instances of databases, queues and cache Changes across code repositories and different programming languages "How can I run the platform on my laptop?"

18. 6 CONSEQUENCESOF SUCH A COMPLEX INFRASTRUCTURE OPS COSTS CHANGE  COMPLEXITYON-BOARDING SPEED FAULT TOLERANCE had to manage multiples instances of databases, queues and cache Changes across code repositories and different programming languages "How can I run the platform on my laptop?" Fault-tolerance is key, but now applies on much more dependencies

19. 6 CONSEQUENCESOF SUCH A COMPLEX INFRASTRUCTURE OPS COSTS CHANGE  COMPLEXITY TESTS ON-BOARDING SPEED FAULT TOLERANCE had to manage multiples instances of databases, queues and cache Changes across code repositories and different programming languages Good note. No other choice than doing TDD ! "How can I run the platform on my laptop?" Fault-tolerance is key, but now applies on much more dependencies

20. 1 STEP Start with a monolith.  Until you are really blocked. WHAT SHOULD WE DO?

21. 1 STEP 2 STEP Start with a monolith.  Until you are really blocked. Use managed services, as much as possible. We replaced all the stateful services by managed alternatives in Google Cloud or compose. WHAT SHOULD WE DO?

22. 3 STEP 1 STEP 2 STEP Start with a monolith.  Until you are really blocked. Use managed services, as much as possible. We replaced all the stateful services by managed alternatives in Google Cloud or compose. If you really require another technology, create another service. WHAT SHOULD WE DO?

23. 3 STEP 4 STEP 1 STEP 2 STEP Start with a monolith.  Until you are really blocked. Use managed services, as much as possible. We replaced all the stateful services by managed alternatives in Google Cloud or compose. If you really require another technology, create another service. Split applications when you are already doing hundreds of deployments a day, and can't deal with more developers WHAT SHOULD WE DO?
