# Kubernetes Deployment

> Overview of Kubernetes Deployment in CometChat.

CometChat on-premise on Kubernetes provides enterprise-grade orchestration for large-scale deployments requiring advanced features like multi-region active-active architectures, dynamic autoscaling, and service mesh integration.

## When to use Kubernetes

Kubernetes is recommended for deployments that meet one or more of these criteria:

**Scale Requirements:**

* Monthly Active Users (MAU) exceeding 200,000
* Peak Concurrent Connections (PCC) exceeding 20,000
* Multi-region or global deployments with active-active failover

**Advanced Features:**

* Dynamic autoscaling based on custom metrics (HPA/VPA)
* Service mesh for mTLS and advanced traffic management (Istio, Linkerd)
* GitOps workflows for declarative infrastructure management
* Cloud-native operators for Kafka, databases, and other components

**Operational Requirements:**

* Sub-50ms latency targets requiring sophisticated traffic routing
* Compliance requirements demanding advanced security policies
* Integration with existing Kubernetes infrastructure

## Kubernetes vs Docker Swarm

| Feature                    | Docker Swarm           | Kubernetes         |
| -------------------------- | ---------------------- | ------------------ |
| **Recommended Scale**      | Up to 200k MAU         | 200k+ MAU          |
| **Operational Complexity** | Low                    | High               |
| **Learning Curve**         | Minimal                | Steep              |
| **Autoscaling**            | Manual                 | Advanced (HPA/VPA) |
| **Multi-region**           | Manual setup           | Native support     |
| **Service Mesh**           | Not supported          | Native integration |
| **Ecosystem**              | Limited                | Extensive          |
| **Best For**               | Mid-market, simplicity | Enterprise, scale  |

## Architecture highlights

**Kubernetes deployment includes:**

* Horizontal Pod Autoscaler (HPA) for automatic scaling based on CPU, memory, or custom metrics
* Vertical Pod Autoscaler (VPA) for right-sizing pod resource requests
* Multi-region active-active deployments with global load balancing
* Service mesh integration (Istio, Linkerd) for mTLS, traffic management, and observability
* Cloud-native Kafka operators (Strimzi, Confluent) for automated cluster management
* Advanced security policies with Pod Security Standards and Network Policies
* GitOps workflows with ArgoCD or Flux for declarative infrastructure management
