Licensing Infrastructure
The infrastructure that supports our licensing mechanisms.
Proposal
Licensing library design after refactoring
Components
LicenseManager (dll)
Resolve licensing aspects for the generic controller
Handling the active license
Downloading new licenses
Validating licenses and execution requests
Check internet settings
LicenseModel (dll)
Representing the license data in a standard way.
Serializing and deserializing the data
Encryption
License WebService:
Provide license files on request
Add new licenses to DB
Query licenses DB
Licensing WebApp:
Provide UX for licensing manager users
Show status of licenses
Create new licenses
Sequence Diagrams
Database Migration
There are currently 3 software components where licenses are created, each of them with its corresponding database:
Studio: for Snow
VBUC CLI License Generator: for VBUC manually generated licenses.
VBUC in Sales Web Flow for automatic VBUC sales.
License Model
After considering Snow, VBUC and other experiences with licenses, this is the purposed LicenseModel:
Pending Questions:
LicenseFile: why is this text field stored in the VBUC DB?
DateIssued: should it be the original date when the license was inserted into the DB? (makes more sense) or the date when the current license file was serialized?
Unmutable License Files: Where to handle ConsumedAccummulatedLines & LastUsedDate?
LicenseType & ExecutionMode: define a generic mechanism to solve all possible scenarios.
Serialization of new files: available in the LicenseModel, or only in a separate private dll?
