MariaDB Cloud Instance Sizes

MariaDB Cloud instance sizes: serverless instances autoscale between 1–2 SCUs (each MCU = 0.5 vCPU + 2 GB), and provisioned instances offer fixed sizes for predictable workloads.

Serverless Instance Sizes

MariaDB Cloud users are not required to specify any instance sizes when launching a serverless database. The Serverless deployment continuously estimates workload requirements and dynamically resizes the database instance to the appropriate size to ensure optimal workload execution.

During the "Tech Preview" phase, all Serverless instances will utilize between 1 and 2 SCUs (Sky Compute Units) during script execution time. Each MCU is equivalent to 0.5 vCPU and 2GB of memory.

Provisioned Instances Size Choices

Instance size choices are specific to the cloud provider, topology, region, and hardware architecture.

💡 the list below provides available sizes as of Sept 2024. Likely to evolve over time. The MariaDB Cloud portal is the best place for accurate information.

REST Client

A REST client can use the MariaDB Cloud DBaaS API to query instance size selections and choose an instance size for a new service.

Query Database Node Options with REST Client

A REST client can query the MariaDB Cloud DBaaS API for the database node instance size selections for a specific cloud provider, architecture, and topology.

To see the available database node instance sizes for a topology, use curl to call the /provisioning/v1/sizes API endpoint with type=server set:

curl -sS --location \
   --header "X-API-Key: ${API_KEY}" \
   'https://api.skysql.com/provisioning/v1/sizes?architecture=amd64&service_type=transactional&provider=gcp&topology=es-replica&type=server' \
   | jq .

    "service_type": "transactional",
    "provider": "gcp",

Query MaxScale Node Options with REST Client

A REST client can query the MariaDB Cloud DBaaS API for the MaxScale node instance size selections for a specific cloud provider, architecture, and topology.

To see the default MaxScale instance size for a topology, cloud, and architecture, use curl to call the /provisioning/v1/sizes API endpoint:

curl -sS --location \
   --header "X-API-Key: ${API_KEY}" \
   'https://api.skysql.com/provisioning/v1/sizes?provider=gcp&architecture=amd64&topology=es-replica' \
   | jq .

[
   {
     "id": "c0666ab8-4a3b-11ed-8853-b278760e6ab5",
     "name": "sky-2x8",
     "display_name": "Sky-2x8",
     "service_type": "transactional",
     "provider": "gcp",
     "tier": "foundation",
     "architecture": "amd64",
     "cpu": "2 vCPU",
     "ram": "8 GB",
     "type": "server",
     "default_maxscale_size_name": "sky-2x8",
     "updated_on": "2022-10-12T14:40:00Z",
     "created_on": "2022-10-12T14:40:00Z",
     "is_active": true,
     "topology": "es-replica"
   }
]

The default_maxscale_size_name attribute shows the default MaxScale instance size.

To see the available MaxScale node instance sizes for a topology, use curl to call the /provisioning/v1/sizes API endpoint with type=proxy set:

curl -sS --location \
   --header "X-API-Key: ${API_KEY}" \
   'https://api.skysql.com/provisioning/v1/sizes?architecture=amd64&service_type=transactional&provider=gcp&topology=es-replica&type=proxy' \
   | jq .

The output can show different instance sizes, depending on whether your MariaDB Cloud account is Foundation tier or Power tier.
