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 it. EC2, CloudFormation, Lambda, BigData, and a lot more. All cool company used AWS.
Kubernetes

Kubernetes

You have a thousands of container and your ass in on fire when you managing it, Kubernetes help you. Create a cluster with few Nodes and you life will be like sweet chocolate. This one rushed into production like Formula 1 car.
Jenkins

Jenkins

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

GoLang

I didn’t met Go yet, but should discover opportunities with this language.

Docker

Docker had turned whole world upside down. It’s a computer program that provide a operating-system-level virtualization also known as containerization. Forgot about virtual machines – past it. Also docker has own orchestration tool called Docker Swarm, but no.. See up on Kubernetes.
Ansible

Ansible

Ansible is the simplest way to automate apps and IT infrastructure. Just wrote a playbook, and forgot about manual work, if you have thousand instance, you cannot allow yourself to do some manual work. Very useful tool to be honest, and you can use it on deployment, delivery, etc.
VMWare

VMWare

Virtualization…yes, based on hardware, the best way when you want to save all data on your servers. VMWare also provides cloud computing, even supports Kubernetes. Cool things if you wanna manage all and even more. If you cannot manage it – it brings a lot of problems.
Terraform

Terraform

Terraform – IaC (Infrastructure as Code). Like it so much. Write once and use it as much as you can. All your infrastructure should be described in code.
