The document discusses cloud computing and its applications for multimedia content. It describes how cloud platforms can address scalability issues that plagued early video services like YouTube. The cloud enables on-demand access to storage, processing power, and delivery resources. This allows multimedia applications and services to easily scale up or down based on real-time usage. The document outlines several opportunities cloud computing provides for multimedia production, content management, consumption, and business models. It also describes achievements in developing a cloud-based multimedia platform and applications.

2. 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
 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

owning to renting” concept
 Evenfor successful web-based services the usage rate
is on average around 10%, but the curve is very spiky

4. Cloud features
 Pricereduction (pay per use)
 Adaptation to the real needs, scalability
The cloud as a
 Device and location independence “commodity”
 Security
 Reliability through redundant multi-sites
 Easy the maintenance CSDF

the multi-media industry?

6. the VOD case, all is about scalability
The YouTube development loop, in a non-cloud era Number of daily views
on youtube.com from
while(true) 2005 to 2008
{
identify_and_fix_bottlenecks();
drink();
sleep(TOO_LITTLE);
notice_new_bottleneck();
}*
The YouTube usage loop
while(!broken)
{ The secret was:
No_simultaneous_use~=exp(no_days) to ensure that the first
}
loop is faster than the
second one

7. the VOD case, all is about scalability
 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
 Today,cloud platforms are addressing intrinsically the
scalability
• Does this means we’ll have tens of successful YouTube(s)?

8. 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
applications
 Business models
