Recent numbers reveals that 57% of Internet traffic is video content. That’s huge. And that is possible because today’s technology enables anyone to create and consume video content. Users are increasingly directing their computing devices and TVs to video content provided by services such as Netflix, Comcast’s Xfinity, Hulu, Amazon Instant Video, and YouTube.

In such an environment, service providers who provide video content face quite a few challenges:

  • Infrastructure costs—for the hardware needed to support the services
  • Operational costs—for providing content for any device, at any time, in any format
  • Monetizing contents
  • Digital Rights managements—to prevent piracy of content
  • Security of user and content

It’s no wonder that providing a cloud-based offering is something that major cloud providers have seen as an opportunity to provide a platform solution for media services.

Azure Media Services from Microsoft sits on top of the Windows Azure infrastructure and provides access to various media services via productized REST APIs.
