PROVISIONING

How is it?

Server provisioning is a set of actions to prepare a server with appropriate

systems, data and software, and make it

ready for network operation

http://en.wikipedia.org/wiki/Provisioning#Server_provisioning

I use one of this systems in production

•Updating•Maintainability•Scalibility

RISKSBug in your configurations

Price of good cookbook (Chef), formula (salt)…

Answer to this problem is…

REUSABILITY

Environments•Production•Develop•Certification•…

Vagrant configuration is shareable
