Many Options for Media Consumers…

• More content choices
• More devices to consume media
• Many ways to get the content to devices
• New experiences

Turns Out There is Massive Complexity

…But How Do You Enable These?

• More content choices
• More devices to consume media
• Many ways to get the content to devices
• New experiences

Key Trend #1

Trend: More content and larger
content formats leads to ever
increasing storage requirements
Implication: Managing storage is
expensive and complex; the cloud
shifts CapEx to OpEx, freeing resources

Key Trend #2

Trend: Requirements for processing
media at scale will continue to increase
Implication: Strategic use of the cloud
was a competitive advantage; now it is
a core competency

Key Trend #3

Trend: Consumers expectations of
“Content anytime, anywhere, any
device” will be the norm
Implication: Media companies are
utilizing the global nature of the cloud
to reach audiences

Key Trend #4

Trend: Consumers’ attention will get
pulled in many directions
Implication: Media companies are
finding new and innovative ways to
engage and monetize
