Defining the Cloud

What is the Cloud?

Cloud can be defined as a standardised IT Capability delivered in a pay-per-use and self-service way.

What are Cloud Services?

Software as a Service SaaS:Software that is owned, delivered and managed remotely by one

or more providers, delivered as a subscription service, for both consumers and business. Examples

include Salesforce or SAP.

Platform as a Service PaaS:A computing platform with an associated set of software applications

delivered by a Cloud Services Provider, delivered as a subscription service. Providers include Windows

Azure and Google App Engine.

Infrastructure as a Services IaaS:The provision of on-demand compute resources with associated

storage and data centre networking capabilities, defined by service outcomes not designs and is paid

based on resource use, allocation, or number of users served. Popular providers include Amazon Web

Services and Dropbox.

Business Process as a Service BPaaS:Software elements of business processes and management

(HR, Payroll, etc.) that is owned, delivered and managed externally and delivered as services. Examples

include Amazon Webstore and Workday.

What is Cloud Computing?

Cloud Computing: A cloud service has three distinct characteristics that differentiate it from other

traditional models;. It is sold on demand; it is elastic (in that a user can have as much or as little of a

service as they want at any given time); and the service is fully managed.

Cloud can provide significant business benefit in many ways including greater flexibility and mobility,

reduced capital expenditure and a more efficient use of services.

Hosting or Active Server Pages (ASP) it is a managed service

The solution for all IT infrastructure issues

Bespoke it is standardised as much as possible

Fixed resource it is scalable and elastic based on demand

A set of large xed and upfront costs it is subscription (pay-per-use)

Common Cloud myths

What is happening in the Cloud?

The traditional service providers are entering the Cloud market and their focus is IaaS, SaaS and PaaS related. This is and is expected to continue to be a hotly contested environment.

1 Hogan Lovells White Paper: A Global Reality: Governmental Access to Data in the Cloud, 18 July 2012

Myth: Cloud is insecure

Truth: Security in the Cloud is

different to traditional models

it requires a new approach to

managing risk1

Myth: I have lost control

of my IT capability

Truth: Diminished reliance on

traditional IT skills by greater

automation means a different

approach to IT service

provision

Myth: The Cloud will

allow me to remove my

IT organisation

Truth: Different IT skills are

required in a retained IT

organisation

Myth: Cloud is just a

way to save on CAPEX and

not an enabler

Truth: Cloud is a business

enhancer through technology

Now recognised as a means to

business advantage not justfor efficiencies
