Automation and tools

As discussed previously, automation is the best way to achieve rapid software delivery. It solves the issue of managing microservices. However, automation tools aren't ordinary IT or infrastructure applications such as Active Directory, BIND (DNS), or Sendmail (MTA). In order to achieve automation, we need an engineer who should have both a developer skill set to write code, particularly in scripting languages, and an infrastructure operator skill set with knowledge related to VMs, networks, and storage operations. 

DevOps is short for development and operations. It refers to the ability to make automation processes such as CI, infrastructure as code, and CD. It uses some DevOps tools for these automation processes.
