ArangoDB is the leading open-source multi-model database, designed to eliminate the complexity of running multiple specialized databases. By natively supporting three distinct data models—documents, graphs, and key-value pairs—within a single database engine, ArangoDB allows you to model your data as flexibly as your application requires.
Whether you are performing high-speed JSON document lookups or exploring deeply nested graph relationships, the ArangoDB Query Language (AQL) provides a single, declarative syntax for all your operations. This "multi-model" approach simplifies your architecture, reduces operational overhead, and ensures that your data layer can evolve alongside your business.
Self-hosting ArangoDB gives organizations a highly scalable, distributed data hub that can handle a wide variety of workloads while maintaining strict control over data placement and high availability.
Key Benefits
- Architecture Simplicity: Replace multiple databases (Document, Graph, KV) with one system.
- Unified AQL: One language for all queries, regardless of the underlying data model.
- Scalable Graph Performance: Perform deep traversals across massive graph datasets.
- Full-Text Integration: Combine search, graph, and document queries in a single operation.
- Operational Efficiency: Simplified backups, monitoring, and scaling across your entire data stack.
Production Architecture Overview
A production ArangoDB Cluster consists of:
- Coordinators: Stateless nodes that handle client requests and distribute work.
- DB-Servers: Stateful nodes that store shards of data and perform computations.
- Agency: A highly available consensus group (Raft) that manages cluster state and metadata.
- Load Balancer: Standard reverse proxy to distribute traffic to Coordinators.
- Persistent Storage: High-performance SSDs/Persistent Volumes for DB-Servers.

arango_data:Kubernetes Production Deployment (Recommended)
The ArangoDB Kubernetes Operator is the preferred tool for cluster management.
# Install the Operator
helm repo add arangodb https://arangodb.github.io/kube-arangodb
helm install kube-arangodb arangodb/kube-arangodb --namespace arango-admin --create-namespace
# Deploy a Cluster
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/master/examples/simple-cluster.yamlBenefits:
- Automated Lifecycle: Upgrades, backups, and scaling handled automatically.
- Self-Healing: The operator ensures that failed nodes are replaced and shards are rebalanced.
- Declarative Config: Manage your entire database topology via standard Kubernetes manifests.
Scaling & Sharding Strategy
- Shard Management: Distribute shards across multiple DB-Servers to balance the load.
- Satellite Collections: Replicate small, frequently joined collections to every DB-Server for near-instant joins.
- Coordinator Scaling: Add more Coordinators to handle increases in concurrent client connections.
Backup & Security
- ArangoDump: Use the official CLI tool for logical backups of individual databases or the entire cluster.
- Authentication: Always enable authentication and use encrypted connections (SSL/TLS).
- Encryption at Rest: Ensure the data volumes on the host system are encrypted.
- Firewalling: Restrict access to port 8529 to only trusted internal networks.
