# MariaDB Cloud Instance Sizes ## 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. ### MariaDB Server For Foundation tier: | Instance Size | Cloud Provider | CPU | Memory | | ------------- | --------------- | ------- | ------ | | sky-2x4 | aws | 2 vCPU | 4 GB | | sky-2x8 | aws, gcp, azure | 2 vCPU | 8 GB | | sky-4x16 | aws, gcp, azure | 4 vCPU | 16 GB | | sky-4x32 | aws, gcp, azure | 4 vCPU | 32 GB | | sky-8x32 | aws, gcp, azure | 8 vCPU | 32 GB | | sky-8x64 | aws, gcp, azure | 8 vCPU | 64 GB | | sky-16x64 | aws, gcp, azure | 16 vCPU | 64 GB | | sky-16x128 | aws, gcp, azure | 16 vCPU | 128 GB | For Power tier: | Instance Size | Cloud Provider | CPU | Memory | | ------------- | --------------- | -------- | ------- | | sky-2x4 | aws | 2 vCPU | 4 GB | | sky-2x8 | aws, gcp, azure | 2 vCPU | 8 GB | | sky-4x16 | aws, gcp, azure | 4 vCPU | 16 GB | | sky-4x32 | aws, gcp, azure | 4 vCPU | 32 GB | | sky-8x32 | aws, gcp, azure | 8 vCPU | 32 GB | | sky-8x64 | aws, gcp, azure | 8 vCPU | 64 GB | | sky-16x64 | aws, gcp, azure | 16 vCPU | 64 GB | | sky-16x128 | aws, gcp, azure | 16 vCPU | 128 GB | | sky-32x128 | aws, gcp, azure | 32 vCPU | 128 GB | | sky-32x256 | aws, gcp, azure | 32 vCPU | 256 GB | | sky-64x256 | aws, gcp, azure | 64 vCPU | 256 GB | | sky-64x512 | aws, gcp, azure | 64 vCPU | 512 GB | | sky-96x384 | aws | 96 vCPU | 384 GB | | sky-96x768 | aws | 96 vCPU | 768 GB | | sky-128x512 | aws | 128 vCPU | 512 GB | | sky-128x1024 | aws | 128 vCPU | 1024 GB | ### **MaxScale** With Power tier, the following instance sizes can be selected for MaxScale nodes: | Instance Size | Cloud Provider | CPU | Memory | | ------------- | --------------- | ------- | ------ | | sky-2x4 | aws | 2 vCPU | 4 GB | | sky-2x8 | aws, gcp, azure | 2 vCPU | 8 GB | | sky-4x16 | aws, gcp, azure | 4 vCPU | 16 GB | | sky-8x32 | aws, gcp, azure | 8 vCPU | 32 GB | | sky-16x64 | aws, gcp, azure | 16 vCPU | 64 GB | | sky-32x128 | aws, gcp, azure | 32 vCPU | 128 GB | | sky-64x256 | aws, gcp, azure | 64 vCPU | 256 GB | ## 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](https://apidocs.skysql.com/#/Offering/get_provisioning_v1_sizes) with `type=server` set: ```bash 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 . ``` ```json [ { "id": "37629543-65d2-11ed-8da6-2228d0ae81af", "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": "2022-11-16T17:15:06Z", "created_on": "2022-11-16T17:15:06Z", "is_active": true, "topology": "es-replica" }, { "id": "37629489-65d2-11ed-8da6-2228d0ae81af", "name": "sky-4x16", "display_name": "Sky-4x16", "service_type": "transactional", "provider": "gcp", "tier": "foundation", "architecture": "amd64", "cpu": "4 vCPU", "ram": "16 GB", "type": "server", "default_maxscale_size_name": "sky-2x8", "updated_on": "2022-11-16T17:15:06Z", "created_on": "2022-11-16T17:15:06Z", "is_active": true, "topology": "es-replica" }, .... ] ``` ### **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](https://apidocs.skysql.com/#/Offering/get_provisioning_v1_sizes): ```bash curl -sS --location \ --header "X-API-Key: ${API_KEY}" \ 'https://api.skysql.com/provisioning/v1/sizes?provider=gcp&architecture=amd64&topology=es-replica' \ | jq . ``` ```json [ { "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](https://apidocs.skysql.com/#/Offering/get_provisioning_v1_sizes) with `type=proxy` set: ```bash 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
