When selecting managed MongoDB on AWS vs GCP vs Azure, developers and teams face critical decisions on performance, cost, and integration. Each cloud giant offers robust options: AWS with DocumentDB, Azure via Cosmos DB, and GCP through MongoDB Atlas partnerships. This comparison uncovers key differences to guide your choice for high-traffic applications or startups.
Managed MongoDB services eliminate infrastructure hassles like backups, scaling, and patching. Yet, Managed MongoDB on AWS vs GCP vs Azure reveals trade-offs in pricing models, global reach, and specialized features. Whether you’re building AI apps or enterprise databases, understanding these helps optimize for 2026 workloads.
Understanding Managed MongoDB on AWS vs GCP vs Azure
Managed MongoDB on AWS vs GCP vs Azure starts with service definitions. AWS DocumentDB offers MongoDB-compatible APIs with native AWS scaling. Azure Cosmos DB provides multi-model support including MongoDB protocol. GCP relies on MongoDB Atlas, a fully managed service running on Google infrastructure.
Each handles sharding, replication, and backups automatically. However, compatibility varies: DocumentDB supports MongoDB 4.0/5.0 APIs but not all operators. Cosmos DB emulates MongoDB v4 but prioritizes its own partitioning. Atlas delivers 100% MongoDB compatibility across GCP regions.
For beginners, managed MongoDB on AWS vs GCP vs Azure hinges on vendor lock-in. AWS and Azure services tie you to their ecosystems, while Atlas offers multi-cloud flexibility, including GCP deployment.
MongoDB Compatibility Levels
- AWS DocumentDB: 99% API compatibility, limited aggregation.
- Azure Cosmos DB: MongoDB v4 API, custom indexing.
- GCP Atlas: Full MongoDB 7.0 support.
Core Services in Managed MongoDB on AWS vs GCP vs Azure
In managed MongoDB on AWS vs GCP vs Azure, AWS DocumentDB shines with cluster management via console or CLI. It auto-scales storage up to 128TB per cluster. Azure Cosmos DB offers global distribution with single-digit ms latency worldwide.
GCP’s MongoDB Atlas provides serverless instances scaling to zero. All three support read replicas, but GCP edges in analytics integration via BigQuery federation. AWS leads in compute variety with Graviton processors for cost savings.
Key differentiator: Cosmos DB’s multi-API support lets you switch from MongoDB to SQL without migration. This flexibility appeals in hybrid setups.
| Feature | AWS DocumentDB | Azure Cosmos DB | GCP Atlas |
|---|---|---|---|
| Auto Scaling | Storage only | Throughput & Storage | Serverless full |
| Global Clusters | Yes | Multi-region writes | Multi-cloud |
| Backups | Continuous | PITR 7 days | OpLog + Snapshots |
Pricing Comparison for Managed MongoDB on AWS vs GCP vs Azure
Pricing defines managed MongoDB on AWS vs GCP vs Azure. AWS DocumentDB charges per instance hour plus I/O requests: a db.r5.large costs $0.154/hour, totaling ~$112/month. Add $0.20/million IOPS.
Azure Cosmos DB uses Request Units (RUs): 1000 RU/s provisioned at $0.008/hour. Serverless billing at $0.25/million RUs suits bursty workloads. GCP Atlas starts at $0.10/hour for M10 clusters, with serverless at $57/TB ingested monthly.
GCP often wins on cost: per-second billing and sustained discounts save 25-40% vs AWS hourly rates. Azure excels for enterprises with reservations dropping 65% off on-demand.
Cost Breakdown Example (1TB, 4000 RUs)
| Platform | Monthly Cost | Free Tier |
|---|---|---|
| AWS | $250 | 750 hours |
| Azure | $220 | 1000 RU/s free |
| GCP | $180 | M0 free cluster |
