Infrastructure with Virtualization


Virtualization enables on-demand-provisioning of servers running several choices of operating systems and customized software stacks. This leaves the consumer to handle OS, middleware and application deployment on self-service virtual machines that can be started and destroyed on demand.

Infrastructure with Virtualization

On-Demand Infrastructure Abstraction

  • Abstraction of the hardware layers
  • Consumer just requests resources now (self service)
  • On-demand growth and reduction (depending on the virtualization tooling)

"Basically, you get as much resources as you need, whenever you want them, available in an instant."

Deployment Scenarios

  • You can have it in-house
  • You can have it in combination with an external data center
  • You can have it provided to you by service providers (Amazon EC2, Windows Azure)

Reasons for utilizing virtual infrastructure

  • Reduce the time it takes to setup new machines
  • Reduce the time needed for administration
  • Increase the number of possible deployments
  • Increase the speed of delivering new software versions
  • Standardize recurring work with automation (e.g. Chef/Puppet/Ansible)
  • Uniformity of production configuration
  • Independence of hardware

The most reliable way to build servers is to remove the natural variances introduced by individuals. So automate!

How hardware planning used to be without virtualization

  • Get exact specifications of hardware needed
  • Order and setup hardware
  • Configure hardware manually
  • Test the whole setup

Hardware planning with virtualization

  • All this work is already done by the infrastructure provider
  • You only have to think about the virtual resources you need

OpenStack as Virtualization Solution

  • OpenStack is a free and open-source infrastructure platform
  • OpenStack is primarily deployed as a flexible infrastructure solution
  • OpenStack consists of a series of interrelated projects that control pools of processing, storage, and networking resources throughout a data center
