Estimator

Size the database. HA topology, plain pricing.

Every replica is billed transparently — no "Multi-AZ multiplier" that doubles your bill while the dashboard shows one resource. Backups bill on actual storage, not on a reserved ceiling.

Each node holds a full copy of your data. Storage scales up to 16 TB per node, sharded beyond that on Mongo / Kafka.

Backups are stored in object storage at $0.04/GB·mo. Point-in-time recovery (below) extends this to any second within the window.

Each replica is billed at the same hourly rate as the primary. Cross-region replication adds $0.005/GB of WAL traffic.

What's in the hourly rate: Engine licensing, minor version upgrades (zero-downtime), connection pooler (PgBouncer / ProxySQL / mongos), Prometheus metrics, slow-query log, SSL certificates, and TLS termination. Free traffic to VMs in the same region.
Engine catalog

Six engines, none of them forked.

Every database runs upstream open-source code on the version you pick. We push patches back, we don't rename APIs, and your connection string works with the official driver.

In every database bill

What you don't have to think about anymore.

Automated backups

Daily full backup plus continuous WAL streaming. Retention from 1 to 35 days. Restore creates a new database — your live data is never touched.

Point-in-time recovery

Restore to any second within retention. Cross-region restore. Practice runs are free — we encourage them.

Zero-downtime upgrades

Minor versions auto-patched in your maintenance window. Major versions are a one-click switchover with replica-first cutover.

Connection pooling

PgBouncer for Postgres, ProxySQL for MySQL, mongos for Mongo. Pooler scales with you; no separate billing line.

Slow-query insights

pg_stat_statements / sys schema / explain dashboards built in. Top 100 queries surfaced with auto-suggested indexes.

Live metrics

Prometheus endpoint, Grafana templates, OpenMetrics for everything else. 1-second resolution on CPU, IO, query rate.

Custom alerts

Per-metric thresholds with webhook, PagerDuty, Opsgenie, Slack, or email. Throttling and incident grouping included.

Read replicas

Async replicas in any live region. Built-in load-balancing across replicas. Promote any replica to primary in under 30 s.

BYOK encryption

AES-256 at rest with customer-managed keys via NimbusNexus KMS. AWS / GCP KMS via federation for migrations.

Audit logging

Every connect, query, and DDL streamed to object storage or your own Kafka. Pre-built SOC 2 / HIPAA / GDPR schemas.

VPC isolation

Private endpoint by default. Public endpoint behind allow-list if you need it. Same-region traffic to your VMs is free.

Forever-free egress

Backups, replication, and reads from your VMs in the same region are all $0. No "data transfer out" line item.

Use cases

What teams typically stack together.

Postgres · Virginia
B2B SaaS primary

OLTP, multi-tenant schema, pgvector for AI features, pg_partman for soft-delete tables. Most teams here run Primary + replica in US-East with SOC 2 + HIPAA.

PG 17 · db-4-16 · primary + replica · 200 GB · PITR
Typical bill$312/mo
MySQL · Virginia
E-commerce backend

Shopify-style storefronts, WooCommerce, Magento serving the North-American market. ProxySQL splits reads to replicas; group replication for write availability.

MySQL 8.4 · db-8-32 · HA cluster · 500 GB
Typical bill$1,090/mo
Kafka · Singapore
APAC logistics CDC bus

Container moves, customs events, warehouse scans streamed off Postgres via Debezium into Kafka topics — fanned out to track-and-trace, dispatch, and analytics. Singapore region keeps lag low to ports across SEA; tiered storage offloads cold partitions to object.

3 brokers · db-4-16 · 1 TB tiered · MM2 to FRA
Typical bill$428/mo
Redis · Los Angeles
Streaming session store

Session tokens, presence, and rate-limit counters for a West-Coast streaming app. Sentinel for failover, cluster mode for sharding beyond 64 GB. LA region keeps p99 RTT under 10 ms for creators on US-West.

Redis 7.4 · cache-4-16 · 3-node cluster
Typical bill$186/mo
MongoDB · Frankfurt
EU document API backend

Flexible schema for headless CMS, customer telemetry, GDPR-resident user records. Replica set for HA, sharding when one node’s storage isn’t enough. All data stays in the EU; backups never leave Frankfurt.

Mongo 7 · db-4-16 · 3-node replica set · 300 GB
Typical bill$406/mo

Logs + observability

Vector logs from VMs and pods, hot tier on Performance NVMe, warm tier on Standard, cold tier on object storage. k-NN plugin for semantic search across audit trails.

The hyperscalers double the compute line for "Multi-AZ" (it’s just a sync replica) and meter every byte of replication traffic. We don’t.

FAQ

Managed database questions.

A database where NimbusNexus handles provisioning, OS and engine patching, daily backups, point-in-time recovery, failover, monitoring, and connection pooling. You write the queries and ship the schema; we keep it running.
Migration

Move from RDS, Atlas, or Cloud SQL. Cutover in minutes.

Stream live changes from your existing database via logical replication (Postgres / MySQL), change streams (Mongo), or replication slot (Kafka). Cut over when the lag hits zero. We pay the source-side egress.
