This document provides an introduction and overview of using Go for backend development, including key topics like parallelism, concurrency, concurrency models, goroutines, and channels. It discusses how Go uses goroutines and channels based on the Communicating Sequential Processes model to allow developers to organize their code to make the most of computer resources without sharing memory between routines. The speaker is introducing Go and how Netflix uses it for services like their Rend proxy.

GDG Chapter Cúcuta!

4. Go
● Simplicity
● Concurrent

5. Parallelism
● It’s about implementation
● But maybe it would not work as you maybe is expecting

6. Concurrency
● ¿how organize your code in order the get the most from your computer
resources?
● Netflix uses Golang for Rend Proxy

7. Concurrency Model
Channels.
GO routines.
GO, concurrency model is
based on CSP.

8. Why organizers may prefer the new
platform…
Don’t communicate by
sharing memory. Share
memory by
communicating.
What’s in it for organizers?
Goroutines

9. Channels

10. ● Netflix uses Golang for Rend proxy
