Containers: Big picture

  • Applications are heart of business.
  • Most of the Applications run on Servers
  • Earlier we used to run one application on each server
  • Then we had hypervisors which helped in creating virtual machines
  • VM’s are great but they are far from perfect
  • Every vm requires its own dedicated OS is a major flaw, Every OS consumes CPU, RAM and other resources that could otherwise be used to power more applications
  • For a long time, big players like Google have been using container technologies to address the shortcoming of vm model
  • But an organization called as Docker Inc has made it very simple to create container which was not the case earlier
  • Companies like Microsoft joined hands with Docker and made changes in their OS to accomodate docker container Preview
