related to user account and credential management. These common management functionalities represent candidates for interoperability standardization. 7.1.3 PaaS Functional Interfaces PaaS functional interfaces encompass the runtime environment with supporting libraries and system components for developers to develop and deploy SaaS applications. Standard-based APIs are often part of a PaaS offering to begin with (such that the PaaS provider can lure existing development away to cloud-based hosting environment). However, data format for backup and migration of application workload, including database serialization/de-serialization, need further standardization to support portability. 7.1.4 Business Support, Provisioning and Configuration In cloud service management areas, the importance of standard data formats and interfaces to describe service-level agreement (SLA) and quality of service (QoS) in traditional IT systems is high. While standards do exist for SLA negotiation and automated service condition matching, the application of these to the fine level of detail expected for large-scale cloud use cases is just developing. Computing resource description and discovery are also a forefront area in need of standardization as consumers transition from buying and managing resources to renting resources in a cloud environment. This is limited not only to raw computing resources

NIST Cloud Computing Standards Roadmap NIST SP500 291 v1.0 53 such as virtualized processing, storage, and networking resources, but also includes higher- level abstractions of application processing resources. A standardization gap identified in a related area is metering and billing of service consumptions; data formats and management interfaces are used to report, deliver and communicate this usage information. 7.1.5 Security and Privacy As cloud systems are typically external components in the consumer organizations overall IT system, especially in the out-sourced (off-site) deployment models, the need to have seamless security integration calls for interoperable standard interfaces for authentication, authorization, and communication protections. The challenges of identity and access management across different network and administration domains are more prominent in the cloud environment as the implementation of these capabilities within the cloud systems is often not the same organization as consumer organization where the identity information originates. Standardization in areas such as identity provisioning, management, secure and efficient replication across different systems, and identity federation will greatly help to improve the identity management capabilities in the cloud. A related area with specifically wide government usage that can benefit from standardization is single sign-on interface and protocols that support strong authentication.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
