Today’s blog post in our “Build Your Private Cloud in a Month” series is the fourth of a 5-part mini-series we’re calling “Deploying Private Cloud Workloads”. This week we (Kevin Remde, Blain Barton and I) are going to detail and demonstrate some of the key areas in System Center 2012 SP1 Virtual Machine Manager that support the foundational concepts and objects in your Private Cloud environment. The mini-series parts are listed here:
1. Hardware Profiles (Monday)
2. Guest OS Profiles (Tuesday)
3. Application Profiles (Wednesday)
4. VM Templates (Thursday) <—Today!
5. Service Templates (Friday)
Required if following along in the lab:
System Center 2012 w/SP1 Virtual Machine Manager should be installed properly on the domain with at least one Hyper-V host managed in the instance. For my lab guide on deploying VMM check here:

What is a VM Template?
VM templates are preconfigured virtual machines images and configurations that are included in the library of Virtual Machine Manager(VMM), which are used for deploying new virtual machines into the environment.
Why is a VM Template useful?
Let’s suppose you have a gold image of Server 2012 that has software and settings customized to your particular needs by templating this image, it can be used to deploy future virtual servers without the need to walk through the same post OS installation steps time and time again. VM templates can also be used as part of a VMM Service deployment as well, where a group of VMs are deployed to handle a given workload. In this case, a web server might already be configured to work in a load balancing scenario so that the deployment of an extra VM into the cloud service takes minimal time. We will not be tackling cloud services in this module today however. Read more
