Three-tiered architecture provides scalability and flexibility.
If overtime, load is increased on the application server, then another application server could be added.
Or simply more memory or CPU could be added to the same application server without disturbing other nodes.
Similarly database server could be upgraded without touching the other nodes.
Also when it is time to upgrade the business logic to a newer version, only application server absorbs the new business logic patches.
