The Army Knowledge Online (AKO) program “is a great embedded computer example of a system that exhibits almost every one of the NIST cloud characteristics in that the NIPRNet version supports broad network access from anywhere in the world via the Internet, user accounts and resources are self-provisioned and support elasticity and spikes in usage, the Embedded Computer infrastructure allows reallocating virtualized resources within or across its multiple data centers, and the system has been designed to support multitenancy and very detailed usage data for potential chargeback,” Cloyd says. “With checks next to each of those essential characteristics, embedded computer could be poised as a great example of Software as a Service (SaaS).” SaaS is the capability provided to the consumer to use the provider’s applications running on a cloud infrastructure, according to NIST. Other types of service include Platform as a Service (PaaS), and Infrastructure as a embedded computer.
