My third (and last) talk at the SELA Developer Practice was about Windows Azure Media Services. If you haven't explored it yet, it's a SaaS offering for uploading, encoding, managing, and delivering media to a variety of devices, scaled by the power of Windows Azure. A couple of months ago this blog featured adetailed overview of one of the proof-of-concept workflows I built with Windows Azure Media Services, so I won't repeat myself.
If you are considering Windows Azure Media Services for your own application or service, feel free to contact me and I'll be happy to help. If you're in Israel, Microsoft Israel would also love to be a fly on the wall in our conversation :-P
