    About Nginx

Nginx is a high performance open source web server which is light-weight and load balancer program which is lighter then Apache HTTP Server.

What is an Ansible?

  • Ansible is, in short, an IT automation, configuration management and provisioning tool.
  • It uses ‘playbooks’ to deploy, manage, build, test and configure anything from full server environments to web site to custom compiled sources for applications.
  • It brings together aspects of environment management that have been traditionally separate and manage indepently. Taking control of your environment with a single tool has anumber of advantages

  • Server deployment configuration
  • Making everything consistent
  • Build or hook into other applications and control them as well
  • Redeploy fresh instance in case of failure.
  • Ansible is very often called an orchestration tool.
  • You can avoid doing the same mistake again and again by automating the configuration and deployment process.
