Windows Licensing

For Windows Operating Systems, Skillable can optionally provide license activation for Windows Server 2012 R2 or newer and Windows Client (10/11) . Windows Server is licensed under Microsoft's SPLA program while Windows Client is licensed using volume licensing.

If you do not have an agreement with Skillable under this program or with Microsoft directly, all Windows licensing is the responsibility of the lab builder.

Limits & Cost Considerations

Skillable provided Windows licensing comes in two forms, both based on a Concurrency Model. Concurrency can be defined as the count of "something" active the same time. For Skillable provided Windows licensing, it is either Concurrent RAM or Concurrent User.

Concurrent RAM Model

Windows Server is offered under a Concurrent RAM model. This means there is a maximum amount of RAM running Windows Server labs at any given time. Windows Server concurrent RAM is offered in increments of 1 Terabyte (TB) (1 terabyte is equivalent to 1000GB). Due to the deployment of labs onto a single host, all VMs in a lab (for example, Linux VMs) also apply to the contracted limit.

Example Concurrency Limit:

The below table assumes a Concurrent RAM limit of 1TB.

1 Windows (10GB RAM)
1 Linux (10GB RAM)

1 Linux (20GB RAM)

1000GB

NO

Exceeding RAM Limit

If users try to launch labs and their lab would cause the RAM Concurrency limit to be exceeded, the user will receive a lab launch error.

Concurrent User

Windows Client is offered in a Concurrent User model. Concurrency can be defined as the count of "something" active the same time.

Concurrent users are currently offered in increments of 15 or 50 (ex: 15, 30, 50, 100, etc.).

When looking to begin using Skillable Windows Client licensing, you will need to calculate the number of concurrent lab users (learners, instructors, and lab developers) in total you will require to support across all of the labs. This will be used to limit the number of simultaneous lab instances and determine the pricing. The number of licenses can be increased at any time, but are an annual commitment.

Example Concurrency Limit:

The below table assumes a Concurrent User limit of 50.

Exceeding license concurrency

If users try to launch more labs than are allocated to a customer, the user will receive a lab launch error.

Other Software Licensing

Skillable can also supply Microsoft Office licensing on request. For any additional software utilized in your labs, it is the responsibility of the lab builder to ensure any licensing requirements are met. Learn more about software licensing.
