DevOps is the need today.
Doing DevOps the right way starts with the right thinking approach. Figuring out the critical processes that you can automate easily.

Even though DevOps may start with the culture but ultimately you need tools to make things work.

My favorite tools when it comes to DevOps are,
Docker
AWS
GitHub
Terraform
Ansible
Splunk
Monit
Shippable
Chef
Slack
