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
