Cutting latency in half requires four times the number of nodes in a system. 9. Don’t put all your eggs in one basket. The reliability of a system with n redundant components and a reliability of r is 1-(1-r)n. 9999 percent (six nines). Large cloud providers with geographically dispersed sites worldwide therefore achieve reliability rates that are hard for private systems to achieve. 10. An object at rest tends to stay at rest (Newton). Private datacenters tend to be located in places where the company or unit was founded or acquired.
Cloud computing obstacles Cloud computing isn’t a panacea; nor is it either practical or economically sensible for many computer applications that you encounter. In practice, cloud computing can deviate from the ideals described in the previous list in many significant ways. The illusion of scalability is bounded by the limitations cloud providers place on their clients. Resource limits are exposed at peak conditions of the utility itself. As we all know, power utilities suffer brownouts and outages when the temperature soars, and cloud computing providers are no different.
Doc) that separate cloud computing into service models and deployment models. 1. The NIST model originally did not require a cloud to use virtualization to pool resources, nor did it absolutely require that a cloud support multi-tenancy in the earliest definitions of cloud computing. Multi-tenancy is the sharing of resources among two or more clients. The latest version of the NIST definition does require that cloud computing networks use virtualization and support multi-tenancy. 1 The NIST cloud computing definitions Deployment models Community Service models Infrastructure as a Service (laaS) Service attributes Hybrid Private Platform as a Service (PaaS) Public Software as a Service (SaaS) Resource pooling Broad network access Measured service On-demand self-service Rapid elasticity Because cloud computing is moving toward a set of modular interacting components based on standards such as the Service Oriented Architecture (described in Chapter 13), you might expect that future versions of the NIST model may add those features as well.
