Orchestration (computing)

Automated configuration, coordination, and management of computer systems and software

In system administration, orchestration is the automated configuring, coordinating, and managing of computer systems and software.[1]

Many tools exist to automate server configuration and management, including Kubernetes, Ansible, Puppet, Salt, Terraform,[2] and AWS CloudFormation.[3]

## Usage[edit]

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

In the context of cloud computing, the main difference between workflow automation and orchestration 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 the quality of service parameters), for example, meet application performance goals using minimized cost[5] and maximize application performance within budget constraints,[6] cloud management solutions also encompass frameworks for workflow mapping and management.
