Cloud Media Processing - Embedded Community - Intel

• Media Processing as a Service (MPaaS) provides
access to specialized platforms, APIs or fullyintegrated
applications that analyze and modify
media data streams. These applications leverage
functions such as audio and video mixing,
multimedia transcoding, recording and playing
a media stream, detecting the “loudest talker”
or noisy connections, and applying voice or video
quality enhancements.
Types of Cloud Computing
Clouds are classified as public, private, hybrid or
community, based on the entities providing computing
resources and networks. A public cloud uses the
mainstream public Internet, which is operated by
and shared across many external organizations.
This model is typical for hosted conferencing service
providers. A private cloud is operated for a single
organization and is common among enterprises for
data security, corporate governance and reliability
reasons. A hybrid cloud combines both public and
private clouds. A community cloud is setup for a
common interest group, and the infrastructure is
maintained by its members.
Transition to the Cloud—
What Does It Mean?
Cloud computing is creating a paradigm shift that
is closely aligned to guiding tenets around how
computing resources are accessed and consumed,
some of which are listed in Table 1. As a result,
customers of cloud services can take advantage of
new features, like dynamic resource allocation and
consumption-based pricing models, that increase their
agility and flexibility.
From the perspective of telecom service providers,
an industry migrating to cloud-based services is
likely to experience fundamental shifts related to
infrastructure, business models and competition.
Drawing on insights from Morgan Keegan 5 at Equity
Research, some of these changes include:

Tenets Implications
Abstract Resources Substitute references to physical servers
and hard drives with instances and volumes.
Cloud resources are fungible. 4
On-Demand Provisioning Get more resources right when they’re needed.
Give back unnecessary resources.
Scalability in Minutes Scale out or in depending on usage needs.
Pay per consumption Don’t pay for resources after they’ve been turned off.
Automation Increase automation using APIs. The cloud provides
access to scriptable infrastructure.
Table 1. Tenants of Cloud Computing
Infrastructure:
• New on-premises infrastructure deployments
give way to cloud-based systems located offsite.
• Transcoding-intensive digital signal processors are
substituted with virtualized COTS infrastructure
based on Intel ® multi-core processor technology.
• Large, upfront equipment expenditures are replaced
by recurring fee (rent) payment models.
Business Model:
• ‘Conferencing as a business’ transitions to
‘conferencing as a service.’
• Interoperability requirements expand from
dedicated equipment to all computing devices.
Competition:
• New entrants take advantage of lower barriers
to entry provided by cloud computing.
• Greater reliance on public networks levels the
playing field.
• Improved interoperability enables new partnership
opportunities.
