13. What are the advantages of hosting Microsoft Lync on Cloud environments like Amazon AWS or Azure?

The biggest advantage is – easy to ‘Scale up and down’

    • For e.g. if the Lync implementation was designed to handle 100 concurrent calls and say for ‘all hands meeting’ which requires support for 500 concurrent calls, once can easily change the server instance type for the short duration of the meeting to support the increased load and after that bring it down. No extra hardware required.
    • And during weekends and holidays (minimum load periods), one can change to smaller instance type and reduce operation cost.

Other advantages are

    • Pay as you use
    • Easy to distribute the servers across multiple geographical locations
