B10, B50, B250, B1000 Licenses are based on the number of user accounts that can be created within an application instance. You can purchase a license that is closest to the number of required user accounts. There is no limit on the concurrent user logins. This license allows using the product on one single domain which you control, and its subdomains which you control, without restrictions based on server, CPU, or core count. The license key is generated with a wildcard domain (e.g. *.contoso.com) and during runtime the HOST header is checked against this wildcard domain. The domain is not required to be public-facing, internal domains/hostnames (e.g. myserver) are also accepted. Note that running locally (eg. localhost or 127.0.0.1) is not restricted, the license domain is checked only when you deploy/publish.
Enterprise License grants enterprise-wide rights (including subsidiaries), but can also be purchased by an individual. This license allows using the product on multiple domains and their subdomains which your organization owns. Unlimited user accounts can be created with this license.
Source License is very similar to the Enterprise License, but in addition it provides full source code for the product. This license allows using the product on multiple domains and their subdomains which your organization and your customers owns.
