Understanding the significance of DevOps in a cloud deployment

Grazed from TechTarget. Author: Tom Nolle.

It’s not uncommon for a technology to gain publicity faster than it gains implementation traction among enterprises, and that’s certainly been true for cloud computing. Some enterprises claim two factors are slowing cloud adoption: difficulty in proving cloud’s benefits and 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. "…

In a utopian world, the description of what the application needs would be written at the same time the application is built. However, because few apps have been developed with DevOps compatibility in mind, not many of them are built in this manner. Until this paradigm changes, one factor for choosing a DevOps tool is to look at how it supports the creation of application descriptions for existing, or deployed, applications…
