The purpose of cloud orchestration in IT is to automate the management and coordination of cloud resources and services. It involves integrating various cloud components to streamline workflows, ensuring that applications and services operate seamlessly across different environments. This orchestration enhances efficiency and improves scalability, allowing organizations to respond quickly to changing demands. By managing configurations, deployments, and resource allocation effectively, cloud orchestration optimizes performance, reduces operational overhead, and supports the overall agility of IT operations.
