Frequently Asked Questions about SkySQL

What is SkySQL?

MariaDB SkySQL is a database-as-a-service (DBaaS) developed and managed by MariaDB Corporation. SkySQL is the only DBaaS to deliver MariaDB Enterprise, with MariaDB Enterprise Server, on expert-maintained multi-cloud infrastructure.

Can I use SkySQL?

Yes. MariaDB SkySQL is available for immediate use. Sign up today and get started. You will be asked to enter credit card information upon launch of your first service.

How do I sign up for SkySQL?

1. Go to https://cloud.mariadb.com/

2. Log in or register for a MariaDB ID using social login or email.

3. Once registered, you can get started right away by launching a service, connecting, and loading data.

Why would I choose a DBaaS over an on-premises deployment?

Our platform and experts handle the infrastructure needs, allowing you to focus on your core business.

When you choose MariaDB SkySQL, a full-featured DBaaS, you forego the capital expenditure of buying hardware, the delay of waiting for new systems to ship every time you need to scale-up or scale-out, and the overhead and opportunity-cost of tuning, monitoring, and upgrading your database. SkySQL also handles routine tasks such as nightly backups and infrastructure maintenance.

And if you need ultimate control, and have the necessary skills and resources to hand-pick instances and tune configurations, we offer SkySQL Power Tier to deliver all of the on-premises benefits without the capex (capital expense) and operational overhead.

How long does it take to deploy on SkySQL?

When it comes time to deploy your SkySQL service, it can take up to 25 minutes for the initial deployment in a region to afford time for your Kubernetes cluster to be provisioned. Consecutive database deployments will use the same Kubernetes environment and take significantly less time.

The real time benefits come every day after, when you're operating at scale. A database node fault could take a short five minutes or less for Kubernetes self-healing, instead of an eight-hour bare metal rebuild as you might see on-premises or on other cloud platforms.

What version of MariaDB does SkySQL support?

SkySQL provides services backed by MariaDB Enterprise Server 10.5 and 10.4, MariaDB Xpand 5.3, and MariaDB MaxScale. MariaDB Enterprise Server incorporates MariaDB Enterprise ColumnStore and MariaDB Enterprise Cluster (powered by Galera). Minor versions are detailed in the release notes.

Are other databases supported?

No. SkySQL is the only DBaaS to deliver MariaDB Enterprise, including MariaDB Enterprise Server, on expert-maintained multi-cloud infrastructure. We're glad to help with your move to SkySQL, whether you're migrating from another database platform or looking to lift-and-shift a MariaDB implementation to SkySQL.

What hardware does SkySQL run on?

MariaDB SkySQL is multi-cloud and as a full-featured DBaaS we handle all of the hardware and infrastructure needs.

Services are currently available with a range of instance sizes running on:

• Amazon AWS (Amazon Web Services) and Amazon EKS (Elastic Kubernetes Service)

• Google GCP (Google Cloud Platform) and Google GKE (Google Kubernetes Engine)

Transactional services (such as our HA (Primary/Replica) topology) operate on:

• AWS with EBS Provisioned IOPS SSD (io1 type) with Amazon EBS encryption

• GCP with Zonal SSD Persistent Disk with Google's default encryption

Analytical services (such as our ColumnStore topology) operate on scalable object storage.

What software stack does SkySQL run on?

MariaDB SkySQL runs on Amazon Elastic Kubernetes Service (EKS), Google Kubernetes Engine (GKE), and MariaDB Enterprise. MariaDB Enterprise includes MariaDB Enterprise Server, MariaDB MaxScale, MariaDB ColumnStore, and MariaDB Xpand. MariaDB Enterprise Server enables a predictable development and operations experience through optimized builds, predictable release behavior, and vendor support.
