Building Microservices with Nodejs

In this talk I present an architecture solution based in asynchronous events, using a Queue that process the events and dispatch to free resources.
This is good for transaction systems, logging and events being processed in background, allowing us to have a decoupled architecture.
Nodejs is used in the examples, and some code snippets are shown during the talk.

3. IT’S ALL ABOUT ARCHITECTURE
4. Microservice Microservice Microservice Microservice Microservice
5. A MICROSERVICE IS A SMALL APP WITH A VERY SPECIFIC PURPOSE IN THE CONTEXT OF AN ENTIRE APPLICATION, AND CAN BE ACCESSED FROM OTHER CONTAINERS OR MACHINES Me
6. REF. 1
7. CAN I USE ANY LANGUAGE FOR EACH MICROSERVICE? "YOU CAN USE ANY LANGUAGE FOR A MICROSERVICE IN THE SAME MANNER THAT YOU CAN RUN A MARATHON IN BOOTS” Joey Clover
8. A MICROSERVICE IS LANGUAGE AGNOSTIC A MICROSERVICE CAN INTERACT WITH ANY OTHER MICROSERVICE A MICROSERVICE ROCKS. NODEJS ROCKS. Me
9. MICROSERVICES WITH NODES
10. MOTIVATION WHEN WE START THINKING ABOUT CLOUD SOLUTIONS, A LOT OF PROBLEMS COME INTO PLAY. A MICROSERVICES’ ARCHITECTURE CAN SOLVE SOME OF THEM, BUT ALSO INTRODUCES NEW CHALLENGES TO YOUR APP.
11. BENEFITS OF USING NODEJS - EASY CODE - FAST CODE - SCALABLE CODE - GET RID OF A LOT PROBLEMS THAT ARE COMMON IN OTHER LANGUAGES
12. SO, WHAT WILL WE DO HERE AT ALL ?
13. WE WILL SHOW HOW TO IMPLEMENT A MESSAGE-BASED SYSTEM
14. A COMMON ANALOGY IS THE POST OFFICE FIRST, A USER DELIVERS SOMETHING AT THE POST OFFICE
15. A COMMON ANALOGY IS THE POST OFFICE AFTER THAT, YOU LEAVE THE PLACE AND EXPECT THAT THE POST OFFICE WILL SEND A PERSON TO DELIVER YOUR PACKAGE
