# MariaDB Cloud vs. RDS

## The DBaaS you wish RDS was.

Rest easy knowing your database is in the hands of the people who built it. Support modern workloads with a database that is inherently resilient, performant, and reliable — without the operational overhead RDS puts on your team.

  SOUND FAMILIAR? 







### It’s a managed database. Why are you still on call?

You chose RDS to get out of the weeds. But RDS manages infrastructure, not consequences. When failover takes two minutes, when a forced upgrade hijacks your quarter, when CPU maxes out and you can’t resize without downtime — that’s still yours to own.

  THE 2AM FAILOVER 

*“RDS failover triggered. DNS propagation in progress. ETA unknown. Customers reporting errors.”*

RDS DNS-based failover takes 60–120 seconds — minimum. You’re awake, watching a timer tick while the incident channel fills up, because **a passive standby can’t take over instantly.**











  THE MIGRATION SPRINT 

*“Major version EOL in 90 days. All teams: migration testing begins next sprint. Feature freeze starts Monday.”*

RDS runs community MySQL/MariaDB with a 3-year EOL cycle. Every few years, **your roadmap gets hijacked** by a high-risk, high-toil forced upgrade — not because your app needed it, but because the community schedule did.



















  THE TRAFFIC SPIKE 

*“Primary CPU at 98%. Read replicas falling behind. Some queries returning stale data. Can we scale?”*

RDS autoscales storage. CPU and RAM are fixed until you resize — which causes downtime. Meanwhile **replica lag compounds under load**, and your app is serving answers from 30 seconds ago.











  THE AI INITIATIVE 

**“We need vector search for the new RAG pipeline. How long to provision and connect a separate service?”**

Every new workload on RDS means another service to provision, connect, and maintain. **Vector search, analytics, transactions** — each one adds another failure point, another bill line, more complexity to deal with.









































  WHY MARIADB CLOUD 







### Fix the four problems RDS can’t.

MariaDB Cloud runs in your existing AWS environment — same infrastructure, radically better database behavior.

  STABILITY 

##### Escape the EOL treadmill

Stop fighting 3-year EOL cycles. MariaDB’s up to 8-year enterprise lifecycle means you set your own upgrade schedule — and spend your time shipping features, not firefighting forced migrations.











  PERFORMANCE 

##### No more single-primary bottlenecks

Every node is active. Scale both reads and writes across the cluster simultaneously — no stale replica lag, no primary bottleneck at peak traffic.



















  RESILIENCE 

##### Failover your app doesn’t notice

RDS DNS-based failover takes 1–2 minutes. MariaDB’s transparent HA uses always-active replicas for instant recovery — no dropped connections, no manual intervention, no incident channel.











  SCALE 

##### Compute that actually autoscales

RDS autoscales storage. MariaDB autoscales CPU and RAM dynamically — handle traffic spikes without pre-provisioning headroom or dropping connections under load.

### What the architecture actually looks like.

Same AWS environment. Very different behavior under pressure.

|  | MariaDB Cloud | RDS |
|---|---|---|
| Failover | Transparent HA: always-active replicas. Sub-second recovery. App sees no interruption. | DNS TTL-based. 60–120s recovery window. App must handle reconnection logic. |
| Scaling | Dynamic compute: CPU and RAM scale on-demand. No resize, no downtime, no dropped connections. | Autoscales storage only. CPU/RAM require instance resize — causes downtime. |
| Replication | Active-active clustering: every node handles reads and writes. Zero lag. Linear write throughput as you scale. | Single-primary with read replicas. Write bottleneck at primary. Replica lag under load. |
| Version lifecycle | 8-year enterprise lifecycle: hardened enterprise binaries. Direct access to the engineers who wrote the code. | 3-year EOL. Forced major version upgrades with community binaries — tested in production by you. |























  ONE PLATFORM 







### Your complete database operations layer.

From first deploy to global scale — without stitching together half a dozen AWS services.

  STEP 1 

###### Deploy

Choose your cloud and region. Launch a hardened enterprise instance in under 60 seconds. SSL, private connections, and load balancing are live from the moment you deploy — zero config required.

**Enterprise binary. Not community.**





  STEP 2 

###### Scale

Go from a single instance to a global, active-active deployment without re-architecting. MariaDB Cloud handles topology, replication, and connection routing. You stay focused on the product.

**Active-active. Cross-region. Cross-cloud.**







  STEP 3 

###### Monitor

Full observability with custom alerts and query-level logs. Plus MariaDB’s Remote DBAs perform proactive health checks — so you stop triaging incidents and start preventing them.

**Remote DBA coverage. 24×7.**





  STEP 4 

###### Evolve

Run transactions, analytics, and vector/RAG workloads on a single platform. No Lambda glue, no separate Aurora clusters, no data sync headaches. One connection string, every workload.

**OLTP + HTAP + Vector. Native.**
