Applications of information technology

This Recommendation specifies a framework of trusted inter-cloud computing and relevant use cases. It provides general requirements for trusted inter-cloud and specific ones related to governance, management, resiliency, security and confidentiality of trusted inter-cloud. The inter-cloud computing concept is based on the relationship (pattern) among multiple cloud service providers (CSPs). This pattern (peering, federation or intermediary) allows the CSP to interwork with one or more peer CSPs to assure intermediation and security of services provided by these CSPs.

Recommendation ITU-T Y.3513 introduces the concept of Infrastructure as a Service (IaaS) and describes its functional requirements. As one of the cloud computing service categories, Infrastructure as a Service provides cloud service customers with computing, storage and network services by cloud service providers. To derive those requirements, relevant use cases are also presented.

Recommendation ITU-T Y.3508 provides an overview and high-level requirements for distributed cloud. This Recommendation introduces the concept of the distributed cloud, and identifies the characteristics of distributed cloud. Based on concept and characteristics, configuration models are illustrated. Deployment considerations of distributed cloud are provided in perspective of infrastructure, network, service, management and security. From use cases, high-level requirements of the distributed cloud are derived.

This standard describes the specifications of the “virtio” family of devices. These devices are found in virtual environments, yet by design they look like physical devices to the guest within the virtual machine. This similarity allows the guest to use standard drivers and discovery mechanisms.The purpose of virtio and this specification is that virtual environments and guests should have a straightfor-ward, efficient, standard and extensible mechanism for virtual devices, rather than boutique per-environmentor per-OS mechanisms.

The Darwin Information Typing Architecture (DITA) is an XML-based architecture for authoring, producing, anddelivering topic-oriented, information-typed content that can be reused and single-sourced in a variety of ways.While DITA historically has been driven by the requirements of large-scale technical documentation authoring,management, and delivery, it is a standard that is applicable to any kind of publication or information that mightbe presented to readers, including interactive training and educational materials, standards, reports, businessdocuments, trade books, travel and nature guides, and more.DITA is designed for creating new document types and describing new information domains based on existingtypes and domains. The process for creating new types and domains is called specialization. Specializationenables the creation of specific, targeted XML grammars that can still use tools and design rules that weredeveloped for more general types and domains; this is similar to how classes in an object-oriented system caninherit the methods of ancestor classes.

The OMG Cloud Working Group publishes vendor-neutral guidance on important considerations for cloud computing adoption, highlighting standards, opportunities for standardization, cloud customer requirements, and best practices to foster an ecosystem of open, standards-based cloud computing technologies.
 
The Cloud Working Group or "CWG" takes over the mission of the Cloud Standards Customer Council™ (CSCC™), an OMG-managed program that launched in 2011 and published 28 deliverables over the course of its operation. The CWG will maintain and update these papers. For more information, watch the webinar, Introducing the OMG Cloud Working Group.

Recommendation ITU-T Y.3520 presents general concepts of end to end resource management in cloud computing; a vision for adoption of cloud resource management in a telecommunication-rich environment; and multi-cloud, end to end resource management for cloud services, i.e., management of any hardware and software used in support of the delivery of cloud services.
