Start with one course site and define which tools instructors will actually use. Test assignment submission and grading with sample accounts, then create a reusable site template. Coordinate authentication, enrollment imports, and support processes with institutional staff, because reliable course access depends on more than the teaching interface alone.
This is best suited to universities and institutions organizing collaborative courses. Before committing a larger project, account for these trade-offs: deployment requires technical administration; local integrations need maintenance.
