What is NIST model in cloud computing?

NIST defines SaaS as a service model where a consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

What is TrueTime API?

TrueTime is an API available at Google that directly exposes clock uncertainty. Comparing to standard datetime libraries, instead of a particular timestamp, TrueTime’s now() function returns an interval of time [earliest, latest]. It also provides two functions: after(t) returns true if t has definitely passed.

Which component of the NIST cloud computing roadmap pertains to the ability to split up applications and reuse components?

Interoperability is the ability to split up and reuse components throughout systems and applications.

What is cloud computing reference architecture?

The CCRA is intended to be used as a blueprint for architecting cloud implementations, driven by functional and non-functional requirements of the respective cloud implementation. The CCRA defines the basic building blocks—architectural elements and their relationships—which make up the cloud.

What are the major 5 properties of cloud computing according to NIST?

The NIST definition lists five essential characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity or expansion, and measured service.

What are the four types of cloud deployment models?

There are four cloud deployment models: public, private, community, and hybrid. Each deployment model is defined according to where the infrastructure for the environment is located.

Is cloud spanner strongly consistent?

Spanner is a strongly-consistent, distributed, scalable database built by Google engineers to support some of Google’s most critical applications. It takes core ideas from the database and distributed systems communities and expands on them in new ways.

What are the three main cloud computing service models?

What are the three common cloud service models?
