Building Scalable Micro-services with Nodejs
3 likes2,095 views
Node.js is well-suited for building scalable micro-services as it allows for building single-threaded and event-driven applications. Micro-services break up monolithic functionality into smaller, independently scalable services that communicate through APIs. While micro-services improve scalability, they also multiply lower-level design problems across codebases. Async libraries help flatten asynchronous code and handle promises to deal with asynchronous I/O in a scalable way. Process managers like pm2 allow scaling node.js micro-services across clusters.

- 8. What is a Micro-Service? Separate monolithic functionality into smaller parts. MY AWESOME MONOLITH git git git gitgit svn? git git Design Pattern
- 9. Then distribute those parts in an individually scalable fashion, behind an API Facade. service API Facade service serviceservice service serviceservice
