Table Of Contents
Main components of application provisioning.
application Logical deployment unit, which defines the relationship between operating
system templates, application components and their dependent services
that can be distributed across multiple virtual machines.
application
components
Custom code used as a template for components such as EAR files, WAR
files, and so on. They are custom script packages for the install, configure,
start, update, rollback, and teardown actions on a node or service.
application blueprint Logical topology of an application for deployment. A blueprint captures the
structure of an application with logical nodes, their corresponding services
and operating systems, dependencies, default configurations, and network
and storage topology requirements.
node Virtual machine defined in the blueprint.
clustered node Cluster of virtual machines defined in the blueprint.
disks Additional disks to be added to the corresponding virtual machine or node.
properties Configuration name-value pairs for services and application components.
These are variables used by the scripts to set parameters on a script and
run various configurations. For example, you can set the installation_path
property value and configure installation scripts to use this property to
specify the path to use to install a service during the application deployment
process.
actions Life cycle stages for the install, configure, start, update, rollback, and
teardown scripts for services and application components to be installed.
storage Space provided by cloud provider to place the disk into different storages to
meet the performace requirements.
deployment profile Collection of deployment settings for a blueprint, including cluster size,
CPU, memory, cloud templates, and networks.
logical network An entity created as a logical abstraction for a network. A logical network is
a cloud agnostic abstraction used to indicate network locality between
nodes in an application. A logical network is dynamically mapped to a cloud
network during the configuration of a deployment profile.
cloud network A network defined within the cloud deployment environment.
