Templates
A template (or a package set) in Parallels Cloud Server is a set of original application files repackaged for use by Parallels Cloud Server. Usually, it is just a set of RPM packages for Red Hat like systems. Parallels Cloud Server provides tools for creating templates, installing, upgrading, adding them to and removing them from a Container.
Using templates lets you:
-
Share RAM among similar applications running in different Containers to save hundreds of megabytes of memory.
-
Deploy applications simultaneously in many Containers.
-
Use different versions of an application in different Containers (for example, perform upgrades only in certain Containers).
There are two types of templates: OS and application:
-
An OS template is an operating system and the standard set of applications to be found right after the installation. Parallels Cloud Server uses OS templates to create new Containers with a preinstalled operating system.
-
An application template is a set of repackaged software packages optionally accompanied with configuration scripts. Application templates are used to add extra software to existing Containers.
For example, you can create a Container on the basis of the
redhat
OS template and add the MySQL application to it with the help of the
mysql
template.
