Shrinking the patching window and provisioning time on private cloud

Patching with RHN Satellite and WSUS, and provisioning with Chef and Puppet, from earlier private cloud work.

By

This is earlier experience, from before the cloud-era work elsewhere on this site. The figures are the engineer's own and are anonymised.

Problem

On a private cloud, the window in which systems stayed unpatched was too long, and provisioning took too long.

What I did

  • Handled patching with RHN Satellite and WSUS.
  • Handled provisioning with Chef and Puppet.

Result

  • Exposure window down 70%.
  • Provisioning time down 70%.

Stack

RHN Satellite, WSUS, Chef, Puppet.
