Microsoft shelving its SDP
According to this report on Telephony Online, Microsoft has shelved its SDP. My initial thoughts are that this is due to the resistance to SDP approach by carriers that have been pursuing IMS and IMS-like blueprints. IMS has its own service delivery function but this mainly supports SIP. SDP does make service delivery easier for telcos by bridging in non-SIP apps as well, but I guess the question carriers might have been asking is: where are the developers?
Microsoft has an army of developers behind it. But most of the 6k developers that BT/Ribbit has, for instance, put together were secured directly and not via Microsoft. Microsoft itself had no more than 900 developers registered with the Sandbox. That I think is the second reason whey SDP has been shelved.
In view of the architectural rigidity exhibited by telcos, Microsoft has been experimenting with the likes of eBay and Amazon for generic mashups (not just communications related mashups) delivery through its SDP. Those people have their own problems right now. I don’t expect them to challenge telcos any time soon. That is reason number 3 SDP has been shelved, I think.
