Managed Databases (MongoDB Business Edition) · $31.2/mo
IONOS MongoDB Business XS at $31.2/mo is moderately priced but faces stiff competition from cheaper managed databases at comparable or better specs. Google Cloud SQL, Heroku Postgres, and Render all offer entry points well below $10/mo, though they use different database engines (PostgreSQL/Redis vs MongoDB). If MongoDB is a hard requirement, UpCloud and Fly.io offer stronger value with higher availability and transparent pricing.
Bare-minimum Cloud SQL instance starts at $0.12/mo; scales affordably with usage and includes 99.99% SLA.
Caveat: Not MongoDB; egress charges and sustained-use discounts require active management to avoid bill shock.
PostgreSQL at $5/mo with 1GB disk and 20 connections; simple, predictable pricing with no surprise renewal traps.
Caveat: Not MongoDB; Essential tier has only 99.5% SLA and no HA, fork, or follow features; upgrade path can force tier jumps on overage.
PostgreSQL at $6/mo with 99.95% SLA; storage and bandwidth overages are transparent and per-GB, not tier-locked.
Caveat: Not MongoDB; storage billed separately at $0.25/GB/month; instances billed by the second so partial-month charges apply.
PostgreSQL at $30/mo with 2GB RAM, 1 vCPU, 25GB disk, 24h backups, and industry-leading 99.999% SLA; only $1.20 cheaper than IONOS.
Caveat: Not MongoDB; backup add-ons carry percentage surcharges (10-60% depending on frequency); data transfer overages possible despite fair-use policy.
PostgreSQL at $38/mo with HA, backups, connection pooling, 2 vCPU, and 1GB RAM; premium but feature-rich alternative if MongoDB is not required.
Caveat: Not MongoDB; storage billed separately at $0.28/GB; region-dependent pricing; no published platform SLA (Enterprise only).
