How to Host MariaDB in the Cloud

Is MariaDB cloud hosted?

MariaDB can run as a fully managed cloud database—reducing ops work while keeping MySQL-compatible features.

Description

Is MariaDB available as a managed cloud service?

Yes. Major providers offer turnkey MariaDB: MariaDB SkySQL (native), Amazon RDS for MariaDB, Azure Database for MariaDB, and Google Cloud SQL for MariaDB. These platforms handle backups, scaling, and patching.

Which cloud option fits an ecommerce workload?

Choose based on latency, compliance, and ecosystem.RDS suits AWS-centric stacks, Azure Database integrates with Azure DevOps, Cloud SQL fits GCP analytics, and SkySQL gives the latest MariaDB features such as ColumnStore.

How do I create a MariaDB instance on AWS RDS?

Use AWS Console or AWS CLI. Define engine=mariadb, version, instance class (e.g., db.t3.medium), storage, and VPC security group.

What connection string should my app use?

After provisioning, copy the endpoint and connect via mysql client or ORM: mysql -h mydb.abc123.us-east-1.rds.amazonaws.com -u admin -p ecommerce.

Can PostgreSQL query cloud-hosted MariaDB?

Yes.Install mysql_fdw, create a foreign server, user mapping, and import schemas so Postgres can SELECT cross-database.

Why use foreign data wrappers?

They allow unified analytics without ETL. Join Orders in Postgres with Products in MariaDB instantly.

What are best practices for production?

Enable automatic backups, multi-AZ or regional replication, restrict inbound traffic to your app, and monitor performance metrics like buffer pool usage.

Common pitfalls to avoid

Under-provisioning instance size causes slow checkouts. Neglecting maintenance windows leads to surprise reboots during peak sales.Plan capacity and schedule updates in off-hours.

How to migrate from on-prem to cloud MariaDB?

Dump data with mysqldump --single-transaction or use AWS DMS/Azure DMS for minimal downtime replication. Cut over after replication lag is zero.

Next steps

Spin up a free-tier instance, load sample ecommerce data, and benchmark query latency. Scale storage or replicas as traffic grows.

How to Host MariaDB in the Cloud Example Usage


-- Combine Postgres Orders with MariaDB Products for revenue per item
SELECT p.name, SUM(oi.quantity * p.price) AS revenue
FROM orderitems oi
JOIN products p ON p.id = oi.product_id  -- products is foreign table from MariaDB
GROUP BY p.name
ORDER BY revenue DESC;

WHERE o.order_date >= CURDATE() - INTERVAL 30 DAY;

# From PostgreSQL using mysql_fdw

Common Mistakes

Mistake: Treating cloud MariaDB like on-prem by disabling automatic minor version upgrades. Why wrong: misses security patches. Fix: Keep automatic upgrades enabled or schedule them during low traffic.
Mistake: Opening the DB to 0.0.0.0/0 for quick testing. Why wrong: exposes data to the internet. Fix: Restrict inbound rules to specific IPs or VPCs, and use SSL/TLS.
