Quotas and limits

This reference describes usage quota and limits that apply to the sandbox environment.

Sandbox hosts

The Instruqt platform supports virtual machines, containers and website services as sandbox hosts:

• For virtual machines, multiple machine types are supported, up to 32 vCPUs and 208 GB of memory.

• For containers, you can allocate up to 8 GB (8192 MB) of memory per sandbox container.

• Each sandbox is subject to a limit of 15 containers and website services combined at any given time. This limitation helps ensure optimal performance and resource allocation for all users.

Google Cloud Platform projects

The following limitations apply to GCP projects you create for learners as part of the sandbox environment.

• Services: You can enable all Google Cloud APIs for learners, except serviceusage.googleapis.com, as this API allows the learner to enable additional services without intervention.

• CPU quota: Every project has a quota of 16 vCPUs per play, and this limitation does not apply to the sandbox hosts.

• Machine types: The following machine types are not available:

  • Memory-optimized (M1, M2)

  • Compute-optimized (C2)

  • Accelerator-optimized (A2)

• GPU quota: Currently allocation of GPU cores is disabled. If you have a legitimate use case for GPU cores, please reach out to your account manager.

Azure subscriptions

The following limitations apply to Azure Subscriptions you create for learners as part of the sandbox environment.

• Virtual machines: Only General-Purpose type VM sizes with 4 vCPU or less are allowed. GPU (and all other accelerated) compute sizes are not allowed.

Refer to the Azure Documentation for a complete list of types/sizes supported.

AWS accounts

The following limitations apply to AWS accounts you create for learners as part of the sandbox environment.

• EC2 Instances: Only General-Purpose instance types are allowed. GPU (and all other accelerated) compute sizes are not allowed. The following list shows the valid machine types.

• Route53 Domain: It's not allowed to register domain names through Route53.
