In Virtual Machine Manager (VMM), a service is a set of virtual machines that are configured and deployed together and are managed as a single entity—for example, a deployment of a multi-tier line-of-business application.
In the VMM console, you use the Service Template Designer to create a service template, which defines the configuration of the service. The service template includes information about the virtual machines that are deployed as part of the service, which applications to install on the virtual machines, and the networking configuration needed for the service (including the use of a load balancer). The service template can make use of existing virtual machine templates or you can define the service without using any existing virtual machine templates.
After the service template is created, you can then deploy the service to a private cloud or to virtual machine hosts. After the service is deployed, you can update the service template and then deploy those updated changes to the already deployed service. Or you can deploy additional virtual machines to an existing service in order to provide additional resources for the service.
Why use services?
|Allows you to configure and manage multi-tier applications as a single entity.||You may have a line-of-business application that is comprised of a web server, an application server, and a database server.|
|Enables you to handle fluctuations in capacity for your application, allowing you to easily add or remove virtual machines needed to support the application.||During the holiday shopping season, your website may need additional web servers deployed to handle the increase in traffic to your site.|
|Provides the capability to separate the operating system configuration from the application installation, allowing you to manage fewer operating system images. This also makes updating the application or the underlying operating system easier.||You may need to deploy a new version of an application or apply a service pack to the operating system.|
