# Environments

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

Environments can be organized in groups and given tags.

{% content-ref url="groups.md" %}
[groups.md](groups.md)
{% endcontent-ref %}

{% content-ref url="tags.md" %}
[tags.md](tags.md)
{% endcontent-ref %}

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

{% content-ref url="access.md" %}
[access.md](access.md)
{% endcontent-ref %}

{% content-ref url="access-groups.md" %}
[access-groups.md](access-groups.md)
{% endcontent-ref %}

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

{% content-ref url="aeec.md" %}
[aeec.md](aeec.md)
{% endcontent-ref %}

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