Orchestration (computing)

Orchestration is the automated configuration, coordination, and management of computer systems and software.[1]

A number of tools exist for automation of server configuration and management, including Ansible, Puppet, Salt, Terraform,[2] and AWS CloudFormation.[3]

Usage

Orchestration is often discussed in the context of service-oriented architecture, virtualization, provisioning, converged infrastructure and dynamic datacenter topics. Orchestration in this sense is about aligning the business request with the applications, data, and infrastructure.[4]

The main difference between a workflow "automation" and an "orchestration" (in the context of cloud computing) is that workflows are processed and completed as processes within a single domain for automation purposes, whereas orchestration includes a workflow and provides a directed action towards larger goals and objectives.[1]

In this context, and with the overall aim to achieve specific goals and objectives (described through quality of service parameters), for example, meet application performance goals using minimized cost[5] and maximize application performance within budget constraints.[6]
