1 Framework and requirements for cloud computing

• ATIS-0200009: The cloud service life cycle checklist establishes a baseline of expectations between
providers who are interoperating cloud services. The document will also be referenced in cloud
service standards to provide a reference model for requirements development. Each enterprise has
an existing governance model. The life-cycle checklist provides a way to extend the process model
between participating companies.

• ATIS-0200006: This document addresses hosted virtual desktop services for medium and large
enterprises. It specifies a federation framework to allow service providers to support high-
performance virtual desktops beyond their normal coverage areas. The document also identifies an
initial set of infrastructure-service interfaces and related requirements. This is a logical basis for the
work on cloud infrastructure federation.

• ATIS-0200010: ATIS Standard ATIS-0200003 provided initial use cases and requirements for content
distribution network (CDN) interconnection between two CDN providers via cache-based unicast
delivery method. ATIS Standard ATIS-0200004 developed use cases and requirements for content
distribution via multicast-based delivery. This standard, ATIS-0200005, extends the use cases and
requirements for an environment involving multiple CDN providers joining together to form a CDN
federation. The interconnection life-cycle use cases and requirements developed in the previous
two ATIS standards are re-examined for the impact arising from a federation of multiple CDN
providers. Additional emphasis is placed on the interconnection domain functionality such that
guidance on the eventual development of network-network interconnect (NNI) architectures and
supporting protocol requirements can be derived.

• ATIS-0200011: This document extends previous ATIS work on multicast-based content delivery
methods to mobile end user devices. Three use cases describe potential situations where such
devices can receive multicast-based broadcasts of specific live events/video content via the 3GPP
Evolved Multimedia Broadcast Multicast System (eMBMS). Delivery processes, assumptions,
content delivery network interconnection implications and supporting requirements are also
provided.
