Knowledge base, projects, code library

 
AWS

Amazon Web Services

Amazon Web Services offers reliable, scalable, and inexpensive (hmm, not sure) cloud computing services. You should learn this guy. EC2, CloudFormation, VPC and a lot of more. All cool company used AWS.
P.S AWS Lambda kill you
Kubernetes

Kubernetes

If you didn’t hear about CI/CD, plz close this page 🙂 Jenkins – it’s a cool tool for build automation CI/CD process. It’s a open source automation server based on Java. Jenkins simple and at the same time powerful tool. Still have a lot of bugs and potholes, but we are hopeless without it (exaggerating)

GoLang

I didn’t met Go yet, but should discover his opportunities

Docker

VMWare

Terraform

Terraform

Terraform – IaC (Infrastructure as Code). Very cool feature, but i didn’t work with Terraform yet
