start using configuration management in 5 steps - cccna14
DESCRIPTION
In this talk, Remi Bergsma explains why you should use configuration management and shows you how to implement configuration management in your existing environment using 5 steps. This can be quite challenging, because when a lot of manual work is done, people are usually very busy. How do you find the time to implement configuration management? Configuration management is a tool that every engineer should use. Especially when used in conjunction with cloud orchestration software, automating your servers and applications really makes sense. No longer think of a server as something that is always there. Think of it as an instance that is automatically setup. You can then have 10s, 100s or 1000s of these servers running. To make this work, you will need to automate the setup of your servers. Configuration management will help you do that.TRANSCRIPT
