Technology Brief : Cloud Computing - Introducing Immutable Infrastructure

The first video in the Cloud Computing series. More information at www.network-insight.net Traditionally, we have physical servers that were costly, difficult to maintain and workflows were time-consuming. Administrators wanted to abstracts a lot of these challenges used virtualization so they could focus more on the application. The birth of virtualization gave rise to virtual servers and the ability to instantiate workloads within a shorter period of time. Similar to how virtualization brings new ways improve server infrastructure, Immutable server infrastructure takes us one step further. Firstly, mutable server infrastructure is servers that require additional care once they have been deployed. This may include upgrade or downgrade or a tweak configuration files for a specific optimization. Usually, this is done on a server by server basis. Secondly, Immutable server infrastructure is servers that are not tweaked after they are deployed. It's an entirely new paradigm where if a change needs to occur a new server is built from a common image along with the required change included in that image. Immutable and mutable can be compared to the pets versus cattle analogy A “Pet” is a special snowflake you have emotional ties towards and requires special handling for example when it’s sick. Unlike “Cattle” that is viewed as an easily replaceable commodity. mutable server infrastructure can be referred to as a Pet & Immutable server infrastructure can be referred to as Cattle.
