Tutorial Objectives
• What is Cloud?– How is this relevant to communications?
• What is the Cloud Services Forum?– How did this group come into being?– What are the goals and objectives?
• How can the CSF interact with other ATIS groups to leverage the current work and knowledge base for Cloud Standards?– How can we ensure compatibility in the Cloud across the
related committee standards?

The Creation of CSF
• The CSF is the newest ATIS Forum. • The CSF was formulated in part to address how
service providers will leverage core network and service attributes to adopt, advance and deliver Cloud computing services. CSF is emphasizing an integrated network/IT perspective in its approach.
• This CSF work draws heavily on business use cases that demonstrate Cloud services' potential.

Broadening Perspective on Cloud (illustrative)
SaaS Business apps (e.g., Salesforce apps, NetSuite apps)
PaaSComputing, Storage (e.g., Google Apps Engine, Rackspace Cloud)
IaaS Computing (e.g., Google or IBM managed hosting, Amazon EC2)
Web-based applications Internet apps
(e.g., Facebook, Android Marketplace)
Network APIs & Device
( e.g., Parlay X / ParlayREST, Presence, MMS, Content Delivery)
Inter-Provider networking services
(e.g., Control Plane, VPNs)

The Service Enablers expose resources (applications, data, and connectivity) through a defined, reusable interface.
Service Interaction Management is used to blend service enablers into a business application.
End users interact with the business application oblivious of the component parts.

Inter-Provider Content Distribution Network
• Network Providers cooperate to cache/distribute content into each other’s networks to download content more locally to users.- Reduced consumption of network resources- Reduced download latency
• Consider the arrangement for doing this as cloud service infrastructure.
• General interest/resonance/willingness to have this item be the initial priority focus in CSF.
