The cloud, another instantiation of the “from owning to renting” concept
Expensive products were, are and will always be rented • Planes • Specialized machines • Trucks • Expensive cars
page 2
What is the correspondence in the digital world? • Computing: early on, large-scale computers such as the IBM 701 were rented $15,000 per month,
• Nowadays: • Storage: few cents/GB/month • Computing: few cents/hour
The cloud, another instantiation of the “from owning to renting” concept
Even for successful web-based services the usage rate is on average around 10%, but the curve is very spiky

Cloud features
Price reduction (pay per use) Adaptation to the real needs, scalability
Device and location independence Security Reliability through redundant multi-sites Easy the maintenance

OK, clouds are good but what they can do for the multi-media industry?

*Cuong Do, 7/10/2008, “Scaling YouTube”, available online
the VOD case, all is about scalability
Number of daily views on youtube.com from 2005 to 2008

No_simultaneous_use~=exp(no_days) }
The secret was: to ensure that the first loop is faster than the second one
The YouTube development loop, in a non-cloud era
The YouTube usage loop
page 7
Why YouTube succeeded and not the other tens of competitors proposing the same service?
• Fast development to solve the scalability bottlenecks due to usage of mature and simple technologies
• Enough investment in infrastructure foreseeing large user number
the VOD case, all is about scalability
Today, cloud platforms are addressing intrinsically the scalability
• Does this means we’ll have tens of successful YouTube(s)?

Cloud4Media : the capacity of the cloud to store, process and deliver multi-media content
Production opportunities • Service Oriented Architecture in IP-based media production • Web 2.0 / User Generated Content
Challenges in content management in distributed environments • Security and Digital Asset Management • Metadata and Wrappers • Multimedia Indexing and Search
Simplifying the consumption terminals • Media encoding/transcoding/adaptation • On-line gaming and cloud gaming • 3D Rendering
Implications for Networks • Need to redesign the networks, especially for interactive and real time media
