4. What are Microservices?
5. Microservices is an architectural style that structures an application as a collection of loosely coupled services
7. App DB
8. App App App
9. Event bus
10. Event bus allows publish-subscribe-style communication between components without requiring the components to explicitly register with one another
11. Microservice principles • Lightweight protocol between services • Small services, one job per service • Service independence • Easier to understand, develop and test • Speeds up development • Enables continues delivery and deployment
12. Why Node.js? • Small and lightweight! • No boilerplate code • Non-blocking I/O • Speed! • Freedom
14. Tools • Docker - containers • Kubernetes - container orchestration • Kafka - messaging • Elastic Stack - logging
16. Docker is a tool designed to make it easier to create, deploy, and run applications using containers
17. Containers allow developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package
18. Dockerfile
23. Kubernetes is an open-source system for automating deployment, scaling and management of containerized applications
25. Service communication
26. Service communication • Synchronous - HTTP/REST API • Asynchronous - Messaging
31. Producer
32. Consumer
37. Conclusion • Use NodeJS! • Use Async communication • Use containers • Use Kubernetes for container orchestration • Log everything to ElasticSearch
