Everything you need to deploy, configure, and run Qdrant in production. These pages cover installation, capacity planning, distributed setups, security, monitoring, performance optimization, and troubleshooting.

## Capacity Planning

[Capacity Planning](/documentation/operations/capacity-planning/index.md) helps you estimate memory and storage requirements based on your vector dimensions, quantization settings, and dataset size.

## Installation

[Installation](/documentation/operations/installation/index.md) covers how to run Qdrant using Docker, from packages, or from source, including basic configuration options.

## Upgrading

[Upgrading](/documentation/operations/upgrades/index.md) explains how to safely upgrade your Qdrant cluster to a new version with zero downtime, including version compatibility and client SDK updates.

## Snapshots

[Snapshots](/documentation/operations/snapshots/index.md) describe how to back up and restore collections at a point in time, for individual nodes or the full cluster.

## Usage Statistics

[Usage Statistics](/documentation/operations/usage-statistics/index.md) explains the anonymized telemetry Qdrant collects and how to opt out.

## Monitoring & Telemetry

[Monitoring](/documentation/operations/monitoring/index.md) covers Qdrant's metrics endpoint, Prometheus integration, and health-check APIs for observability.

## Security

[Security](/documentation/operations/security/index.md) explains how to enable API key authentication and TLS to secure your Qdrant instance.

## Troubleshooting

[Troubleshooting](/documentation/operations/common-errors/index.md) lists common errors and their solutions to help diagnose issues quickly.

## Configuration

[Configuration](/documentation/operations/configuration/index.md) documents all available Qdrant configuration file settings and environment variable overrides.

## Administration

[Administration](/documentation/operations/administration/index.md) covers runtime administration tools, including recovery mode and collection locking.

## Distributed Deployment

[Distributed Deployment](/documentation/operations/distributed_deployment/index.md) explains how to run Qdrant as a multi-node cluster, including sharding, replication, and consensus.

## Running with GPU

[Running with GPU](/documentation/operations/running-with-gpu/index.md) describes how to enable GPU-accelerated indexing using dedicated Qdrant Docker images for NVIDIA and AMD GPUs.

## Optimize Performance

[Optimize Performance](/documentation/operations/optimize/index.md) walks through three main strategies for tuning Qdrant for high speed, low memory, or high precision workloads.

## Optimizer

[Optimizer](/documentation/operations/optimizer/index.md) describes the background optimizer process that rebuilds segments to improve search performance over time.
