# Environment-related

In Portainer terms, an *environment* is an instance that you want to manage through Portainer. Environments can be Docker, Docker Swarm, Kubernetes, ACI or a combination. One Portainer Server instance can manage multiple environments.

User access can be managed within environments, within environment groups, or using polices to define access for multiple environments at once.
