The PlateSpin Orchestrate Server
The PlateSpin Orchestrate Server is the gateway between enterprise applications and resource
servers. The server has two primary functions:
To manage the resource servers
To manage jobs to run on the computing resource
In the first function, the server manages the computing resources by collecting, maintaining, and
updating their status availability, service cost, and other facts. Changes to the computing resources
can be made by the administrator.
The second function of the server is to run remote applications—called jobs—on the computing
resources. The Orchestrate Server uses a policy-based broker and scheduler to decide when and how
a job should run on the computing resources. The decisions are based on many controlled factors,
including the number of computing resources, their cost, and a variety of other factors as specified
by the policy constraints set up by the server administrator. The Orchestrate Server runs the job and
provides all the job's output responses back to the user. The server provides failover capabilities to
allow jobs to continue if computing resources and network conditions degrade.
The PlateSpin Orchestrate Agent
The PlateSpin Orchestrate Agent is installed on all computing resources that are to be managed. It
runs jobs under the management of the Orchestrate Server.
