What is a digital enterprise?
 Boundaries have changed!
 Technologically
 Infrastructure
 Data
 Interpersonally
 Within and across organisations
 Between organisations and public

The requirements for IT have to reflect this
Digital transformation

Now: the Cloud

The Cloud

Capacity
Resources

Web is overtaking/has overtaken desktop
Mobile is replacing local
Utility-based computing is replacing once-off purchase
 Makes resources seem endless
 Lowers risk in terms of usage (pay as you go)

Types of Web Services in the Cloud

Can be thought of as three kinds of services
1.
Software as a Service (SaaS)
 Software function taken off your computer and hosted online
 No need to worry about installation, setup and running of the
application - the service provider does that for you
 E.g. Gmail, Dropbox, Facebook
 Sometimes called ‘On-demand Software’
Types of Web Services in the Cloud
2.
Platform as a Service (PaaS)
 Providers deliver a computing platform typically including
operating system, programming language execution
environment, database, and web server
 Basically gives you a platform in which to develop services at low
cost
 E.g. Elastic Beanstalk, AppFog
3.
Infrastructure as a Service (IaaS)
 Providers deliver the equipment used to support operations,
including storage, hardware, servers and networking
components. Provider owns the equipment and is responsible for
housing, running and maintaining it.
 E.g. Amazon Web Service, MS Azure, Google Compute Engine
 Sometimes called ‘hardware as a service’

The Cloud

This has meaningful implications for data in terms of
 Capacity
 Measurement
 Integration
 Security
 Privacy
 Greenness
