| Who runs it | AceMQ engineers with partner MySQL specialists, under a contract with a 15-minute emergency response. | AWS runs the managed instance. You decide when to take a major version upgrade: AWS never makes one automatically. | AWS. A MySQL-compatible engine that reuses MySQL code, with its own version numbers, release cycles and deprecation timelines. | Oracle's managed MySQL service, with analytics, lakehouse, machine learning and generative AI features. |
|---|
| Where it runs | Your cloud account, data centre or Kubernetes (Tier 3), or infrastructure AceMQ runs (Tier 4). | AWS. | AWS. | Oracle Cloud Infrastructure, AWS and Azure, each with its own service guide. |
|---|
| Which engine and versions | MySQL 8.4 LTS, and 8.0 while you move off it. 9.7 LTS is scoped case by case. | MySQL Community 8.4 and 8.0, with 8.0 under paid Extended Support since 1 August 2026. | Aurora's own version line: check AWS for the dates that apply to yours. | Oracle's MySQL, with HeatWave's added features. |
|---|
| Staying on MySQL 8.0 | We can operate it, but Oracle ships no new fixes for it, so the service plans the move to 8.4 LTS. | A fee: Extended Support pricing starts 1 August 2026, steps up on 1 August 2028 and ends 31 July 2029. | Follows Aurora's own timelines, not MySQL's. | Follows Oracle's terms for the service. |
|---|
| Best when | You have an existing estate, want data inside your own boundary, run on Kubernetes or on premises, or want one contract across databases and messaging. | You are on AWS and want AWS to run a standard MySQL instance. | You are on AWS and want Aurora's engine and accept that it is not stock MySQL. | You want analytics and machine learning next to your MySQL data in Oracle's service. |
