# Calico Documentation

> Calico documentation for networking, network security, and observability for Kubernetes, including Calico Open Source, Calico Enterprise, and Calico Cloud.

## Top Pages

- [Calico quickstart guide](https://docs.tigera.io/calico/latest/getting-started/kubernetes/quickstart): Install Calico Open Source on a single-host Kubernetes cluster in roughly 15 minutes — the standard starter path for trying Calico networking and network policy on a development machine.
- [Quickstart for Calico Enterprise on Kubernetes](https://docs.tigera.io/calico-enterprise/latest/getting-started/install-on-clusters/kubernetes/quickstart): Stand up Calico Enterprise on a single-host Kubernetes cluster in about an hour for testing, demos, or development — not intended for production.
- [What happens when you connect a cluster to Calico Cloud](https://docs.tigera.io/calico-cloud/get-started/connect-cluster): What happens when you connect a Kubernetes cluster to Calico Cloud — what is installed, what data leaves the cluster, and what changes in the cluster.
- [Determine best networking option](https://docs.tigera.io/calico/latest/networking/determine-best-networking): Compare networking options in Calico Open Source — overlay versus non-overlay, BGP routing, CNI choices, and IPAM modes — to pick the right combination for your environment.
- [Get started with Calico network policy](https://docs.tigera.io/calico/latest/network-policy/get-started/calico-policy/calico-network-policy): Write your first Calico Open Source NetworkPolicy — sample policies that exercise the rich rule features that extend Kubernetes NetworkPolicy.
- [Get started with policy tiers](https://docs.tigera.io/calico-enterprise/latest/network-policy/policy-tiers/tiered-policy): How tiered policy works in Calico Enterprise — evaluation order, pass actions, and using tiers to enforce microsegmentation across teams.
- [Enabling the eBPF data plane](https://docs.tigera.io/calico/latest/operations/ebpf/enabling-ebpf): Switch a running Calico Open Source cluster to the eBPF data plane through automatic Tigera Operator detection on kubeadm clusters or a manual configuration path.
- [Observability and troubleshooting](https://docs.tigera.io/calico-enterprise/latest/observability/): Observe and troubleshoot self-managed Calico Enterprise clusters with Manager UI dashboards, Service Graph, packet capture, and Elasticsearch logs.
- [Configure BGP peering](https://docs.tigera.io/calico/latest/networking/configuring/bgp): Configure BGP peering for Calico Open Source — full mesh, node-specific peers, top-of-rack switches, and Calico route reflectors — using BGPPeer and BGPConfiguration resources.
- [System requirements](https://docs.tigera.io/calico-cloud/get-started/system-requirements): Cluster, platform, and version requirements a Kubernetes cluster must meet before it can connect to Calico Cloud.

## Use Cases

- [Microsegmentation](https://docs.tigera.io/use-cases/microsegmentation): Calico enables robust microsegmentation in Kubernetes environments, offering granular isolation and enhanced security for containerized applications.
- [Observability](https://docs.tigera.io/use-cases/observability): Observability is used to find and troubleshoot issues with workload communications, performance, and operations in a Kubernetes cluster.
- [Egress access controls](https://docs.tigera.io/use-cases/egress-access-controls): A guide for using Calico's egress access controls.
- [Egress gateways](https://docs.tigera.io/use-cases/egress-gateways): Egress gateways can streamline your Kubernetes network security, offering fixed IP management, integration with external firewalls, and detailed traffic auditing to safeguard your deployments.
- [Cluster mesh](https://docs.tigera.io/use-cases/cluster-mesh): Cluster mesh enables cross-cluster communication, service discovery, and federated endpoints in a Kubernetes-native way.
