Keystone (OpenStack Identity service)

Keystone is an essential component of OpenStack, which is a cloud computing platform. Think of Keystone as the identity and access management service for OpenStack. It handles user authentication, ensuring only authorized individuals can access resources. Keystone manages users, roles, and permissions, allowing organizations to securely control who can do what within their cloud environment. This centralized identity service simplifies the process of managing access to various cloud services, making it easier to maintain security and compliance in a cloud infrastructure.
