# 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.

Endpoints were renamed to Environments in version 2.10.

Environments can be organized in groups and given tags.

{% endcontent-ref %}

{% content-ref url="environments/tags" %}

{% endcontent-ref %}

Access to environments can then be managed on a per-environment or per-environment group basis.

Automatic onboarding scripts can be generated for larger Edge Agent deployments.

Edge Agent environments can be updated (and updates rolled back) directly from within Portainer.
