CFV 1091 Introduction to Cloud Computing
Measured services
Enables billing of cloud services Resource monitoring helps providers with capacity and service planning
3) Resource pooling
Enables providers to improve resource utilization and to flexibly provision and reclaim resources Multi-tenancy - refers to an architecture in which multiple independent consumers (tenants) are serviced using a single set of resources
Service arbitrage
Similar to service aggregation except, that the services being aggregated may vary
Rapid elasticity
The ability for consumers to quickly request, receive, and later release as many resources as needed Consumers may be able to avoid excessive costs from over-provisioning resources
Service aggregation
The broker combines and integrates multiple services into one or more new services
Service intermediation
The broker enhances and adds value to a given service
Cloud services brokerage (CSB) (defined)
CSB is an IT role and business model in which a company or other entity adds value to one or more cloud services on behalf of one or more consumers of that service An entity that acts as an intermediary between cloud consumers and providers
3) Software as a Service (SaaS)
The consumer DOES NOT manage or control anything, nor the individual application capabilities - Example; Dropbox, MS Office online. You just use the application
2) Broad network access
Consumers access cloud services on ANY client/end-point device from anywhere over a network
1) On-demand self-service
Consumers use a web-based portal to view a service catalog and request cloud services Enables consumers to provision cloud services in a simple and flexible manner No human interaction
1) Infrastructure as a service (IaaS)
The consumer has control over the OS, storage, and deployed applications The consumer DOES NOT manage or control the underlying cloud infrastructure
2) Platform as a Service (PaaS)
The consumer has control over the deployed applications The consumer DOES NOT manage or control the underlying cloud infrastructure including network, servers, OS, or storage
Three primary cloud service models
1) Infrastructure as a service (IaaS) 2) Platform as a Service (PaaS) 3) Software as a Service (SaaS)
Five Essential Cloud Characteristics
1) On-demand self-service 2) Broad network access 3) Resource pooling 4) Rapid elasticity 5) Measured services
Three Categories of CSB
1) Service intermediation 2) Service aggregation 3) Service arbitrage
Cloud Computing Defined
A cloud is a collection of network-accessible IT resources Consists of shared pools of hardware and software resources deployed in data centers
Cloud service models (defined)
A cloud service specifies the services and capabilities provided to consumers Three primary cloud service models
