# Size the Domino Platform

The resource needs of the Domino Platform depend primarily on the peak user demand the deployment aims to support. User demand is the number of users and the amount of work they’re starting in Domino. You can measure this by the peak number of concurrent executions. The resources used by those executions do not substantially change the effect on the Domino Platform, therefore, you must scale around the total number of executions.

The following diagram shows the Domino Platform supplying essential lifecycle, data, and support services to user executions running on the Domino Compute Grid. Regardless of the size of the compute grid infrastructure or resources requested by each compute pod, when the compute grid manages concurrent executions, it will max out its capacity to supply the essential services.

For the default size shown, the [maximum number of concurrent executions is 300](/6.3/admin/infrastructure-and-compute/sizing-the-infrastructure). See [Standard Domino Platform](/6.3/admin/infrastructure-and-compute/sizing-the-infrastructure/size-the-domino-platform/standard-size) for more information.

For more sizing options, see [Large Domino Platform](/6.3/admin/infrastructure-and-compute/sizing-the-infrastructure/size-the-domino-platform/large-size) and [XL Domino Platform](/6.3/admin/infrastructure-and-compute/sizing-the-infrastructure/size-the-domino-platform/xl-size).
