# Amazon Aurora vs ScaleGrid

Canonical: https://inetgeek.com/compare/amazon-aurora-vs-scalegrid/

Every value below is read from Amazon Aurora's and ScaleGrid's own documentation. See https://inetgeek.com/methodology/ for how.

## At a glance

| Criterion | Amazon Aurora | ScaleGrid |
| --- | --- | --- |
| Free tier | Yes — capped Free plan plus time-limited credits | No |
| Pricing model | Pay per use with no plan fee: instances plus storage plus I/O, or ACU-hours in serverless mode. AWS's own worked example prices serverless compute at $0.12 per ACU-hour on Aurora Standard and $0.156 on Aurora I/O-Optimized in US East (N. Virginia) — the difference being whether I/O is metered separately or folded into a higher compute and storage rate. Provisioned instances also offer Reserved Instance pricing, and usage may qualify for Database Savings Plans against a committed hourly spend. | Two models: Dedicated Hosting, an all-inclusive plan covering machine, disk and network cost; or Bring Your Own Cloud (BYOC), management-only pricing where the cloud provider is billed separately. |
| Regions | 34 AWS regions, the same list for the MySQL- and PostgreSQL-compatible editions. Counted from the two availability tables in Aurora's own docs, which publish the regions and no total. | Six cloud providers: AWS, Google Cloud, Microsoft Azure, DigitalOcean, Oracle Cloud (OCI) and Akamai. Specific regional availability is not published on the pricing or product pages. |
| Engine | MySQL- and PostgreSQL-compatible. Aurora is AWS's own engine rather than a hosted build of either, so compatibility is the claim being made — existing code, tools and applications are stated to work, which is not the same as being the upstream database. | MySQL, PostgreSQL, MongoDB, Redis, RabbitMQ and SQL Server. |
| Backup retention | 1 to 35 days. Unlike an RDS DB instance it cannot be set to 0 — Aurora backs the cluster volume up continuously and there is no way to turn that off. | Up to five backups per deployment on ScaleGrid's dedicated hosting plans. |

## Which should you choose?

Pick Amazon Aurora if Teams on AWS who want a Postgres or MySQL cluster that can throw off a copy-on-write clone of production in minutes, keep up to fifteen readers behind it, and pause to nothing between bursts in serverless mode.

Pick ScaleGrid if Teams that already have a favored database engine and cloud provider but want someone else operating it — the BYOC model bills infrastructure at cost and adds management on top, worth it if the operational burden is the actual problem.

Consider something else: Amazon Aurora — You want the upstream database rather than a compatible one, or a branch workflow rather than a clone. AWS documents cloning as a way to build a test environment, not as something you do per pull request.

Consider something else: ScaleGrid — The workload fits a single-engine specialist with its own scale-to-zero or branching model — ScaleGrid's value is operating an engine you already chose, not offering a distinctive one.

## Documented by only one

- Startup credit program: ScaleGrid: Startup Saver: up to 50% discount on ScaleGrid hosting for 12 months.
- Scales to zero: Amazon Aurora: Supported — serverless capacity mode only
- Database branching: Amazon Aurora: Limited — clones, not a branch workflow
- Point-in-time recovery: Amazon Aurora: Any point inside the backup retention period, so up to 35 days. Aurora's backups are continuous and incremental against the cluster volume rather than periodic snapshots plus log replay, which is why AWS states no performance impact while they are taken.
- Read replicas: Amazon Aurora: Supported — 15 per cluster, a quota AWS will not raise
- Rewind in place: Amazon Aurora: Limited — Aurora MySQL edition only
- ISO 27001: Amazon Aurora: Covered under AWS's account-wide ISO/IEC 27001:2022 certification — not scoped per-service the way SOC, HIPAA and PCI DSS are on AWS's own site.
- HIPAA: Amazon Aurora: Listed as a HIPAA-eligible service on AWS's own reference page.
- GDPR / data residency: Amazon Aurora: AWS customers can process personal data on all AWS services in compliance with GDPR, and choose the storage type and geographic region for their data.
