The Core of Microservice Architecture(First Approach)
- 1. The Core of Microservice Architecture Our first approach
- 2. Agenda The Core of Microservice Architectue? Microservices 101! N-th time! Snack(Coffee please!) Docker 101. Basic Principles Lily! Evolution to microservices Python and microservices - Doing Image Recognition ! Kotlin o.O and microservicios – Sending an email and building a batch process! Java and microservices – Dealing with the business and building a profile!
- 3. ¿The Core of Microservice Architecture? Our group • Shared knowledge + Logic • Curiosity • Colleages with passion and time to discover new stuff
- 4. ¿The Core of Microservice Architecture? Brian Torres • Developer • Boss monster player(He is really bad with this one) • Chamo #1 Manuel Puicon • Developer • Big fan of DB(Not databases.. Dragon Ball) Edith Puclla • DevOps Expert • The only member of the team that is not damaged(But be careful…) German Sanchez • Our Frontend Geek • For a strange reason everybody focus fire him when we are playing any game! xD • Chamo #2 Enyert Viñas • Developer... In love with FP! • Board game and MMORPG big fan • Chamo #3
- 5. ¿The Core of Microservice Architecture? What are we looking for? • Learning about new technologies • Share our (working && researching) experience • Build core concepts about microservice architecture • Create a wonderful community
- 6. ¿The Core of Microservice Architecture? Searching for the core… What is this? • Core? • Guidelines + Best practices • Tech Tools • Culture(Like always… This is the critical factor
- 7. Microservices 101! N-th time! Monoliths! A Little bit of history
- 8. Why break the MONOLITH? The application increases, the code increases Only a specific stack Something fails, Everything fail Obligatory escalate everything A development impacts other developments
- 11. What is a MICROSERVICE? • API web • Little code • Connection Enterprise bus • SOAP • Configuration within the code • Process Waterfall NOT a microservice • Independent functional component • Independent deploy • Independent scalability • Decentralized management YES a microservice
- 13. Browsers Apache NGINX Tomcat Application UI Layer Business Layer Database Layer Databases
- 15. Advantages Application UI Layer Booking Service Payment Service Application UI Layer Booking Service Payment Service Fall Down
- 16. Advantages API Gateway Payment Service Booking Service API Gateway Payment Service Booking Service
- 17. Advantages Application – Java Monolithic UI Layer Booking Service Payment Service What do you think about develop this service in NodeJS? What do you think about develop this service in Python?
- 20. Application – Java Monolithic UI Layer Booking Service Payment Service Update the booking service Advantages
- 21. Disadvantages Handle request between your modules
- 22. Disadvantages Multiple databases and transaction management
- 23. Testing a microservices-based application can be cumbersome. Disadvantages
- 24. Ready micro-services!!! Lily NOW?? Remember.. - Patterns - Several Languages - Pros / Cons
- 27. What is python?
- 28. Guido Van Rossum
- 29. Why Python? Easy to use Rapid prototyping Great libraries for image processing Create almost anything
- 30. Why Python? public class Main { public static void main(String[] args) { System.out.println("hello world"); } } print(‘hello world’)
- 31. KOTLIN and MICROSERVICES Open Source, JVM Spring Framework 5.0 support + Spring Boot Interoperability with libraries written in Java
- 32. Who officially using Kotlin?
- 33. Why? • Maturity. • Updates • CPU Business: • Specialists search • The big proyects are written in java Java.. Micro-services.. Why?
- 34. Why there are many companies that change to java?
- 35. Coincidence?????
Editor's Notes
- #25: Y ahora?? Cómo atacarlo Recordando Lo que queda Comenzar a dividir el monolito La estratégia Que debo separr Separar todo Reescribir código
- #26: Destripando al monolito
- #27: Destripando al monolito Dependencia monolito con micro-servicios hasta el final
- #34: Por qué Java? Robusto Java 8 Lambda, API Stream -> Java 9 CONCURRENCIA A nivel empresarial - Se Adoptan el lenguaje desde la universidad. - Si el core del monolito está en java, es menos caro mantener el mismo lenguaje que re-escribir el proyecto a uno nuevo. - Muchos lenguajes en micro-servicios no es factible económicamente. A nivel personal Yo veo a kotlin como otro lenguaje, OJO aclaro tambien lo aprenderé, por si las moscas.
- #35: Casos puntuales
- #36: Netflix(publicación) – por core en java Twiter(publicación 2011) –ruby o phyton iniciando – mejorando su motor de búsqueda java- Lucene Uber (publicacion2016) – Por lo que comentó su arquitecto Matt Ranney a InfoQ, nunca se habrían imaginado el coste que suponía el escribir los microservicios en lenguajes tan diferentes. “migrando a Node.js,Go y Java. Java se usa para los servicios de mapas” OJO La JVM es mucho más eficaz que cualquier lenguaje interpretado. La JVM suele tener un arranque más lento que muchos intérpretes. Eso no es un problema cuando creas servicios. Concurrencia.
