Some enterprises claim two factors are slowing cloud adoption:
- Difficulty in proving cloud’s benefits
- An inability to make cloud operations run as efficiently as data center operations.
DevOps could offer at least a partial solution to both problems.
DevOps is an attempt to pass along knowledge about an application’s need for resources and connectivity from the developers — who build in those dependencies — to the operations teams. The goal of DevOps is to describe application needs in a way that provisioning tools can read so that deployment becomes automatic. By organizing how applications are deployed, it’s possible to automate the processes that monitor application health and restore functionality if a failure occurs.
Central to the DevOps concept is the ability to determine application resource needs. Depending on the specific DevOps tool, this is determined by a feature called a “template,” “model,” “container” or even “charm. “

ON, August 29th 2012, Thomas Bushnell, the tech lead of the group that manages and distributes Linux to Google’s corporate desktops unveiled Goobuntu from behind Google’s curtain at LinuxCon, the Linux Foundation’s annual North American technical conference, First things first, can you download Goobuntu to run it yourself? Well yes and no.
Bushnell explained that “Goobuntu is simply a light skin over standard Ubuntu.” In particular, Google uses the latest long term support (LTS) of Ubuntu. That means that if you download a copy of the latest version of Ubuntu, 12.04.1, you will, for most practical purposes, be running Goobuntu.
