Agenda
1. Views on the Cloud
2. Public versus Private
3. The Three Main Areas of Cloud Computing
4. The Key Attributes of Cloud
a) Costb) Securityc) Operations
5. Does the Cloud have a Role in Your Organisation?
Some Views on Cloud Computing
3So what is it all about?
Public, Private or Hybrid Clouds
4
Public: A service that is available to anyone that will pay for it.
Private: A service running on your own infrastructure
Hybrid: A combination of the two.
Common technical themes:
Environments rely heavily on virtualisation. Shared resources which can be switched rapidly to where they are needed. Much more efficient use of resources than pre virtualisation technology.
Terms You Will Come Across
5
There is overlap between these but essentially there are three terms in use today:
SaaS Software as a Service eg. Salesforce
PaaS Platform as a Service eg: Microsoft Azure
IaaS Infrastructure as a Service eg: AWS, Amazon Web Services
What is the big change from what we used to have?
The Big Change is Not Technical it is Largely Approach
6
The retailer approach to IT Infrastructure
The key things about a retailer:
Cost transparency, the price is marked on the product
Cost is actionable, it can be compared and if it is too much you can go somewhere else
You buy what you need, not what you might need
Customer loyalty is earned, if you don’t like the experience you go somewhere else next time. You are not usually locked into any single retailer.
Key Attributes of Cloud – 1. Cost

Here are the clear and transparent prices for Amazon EC2 (elastic compute) servers.
Key Attributes of Cloud Computing – 2. Security
8
The bottom line is that you are responsible for security.
Issue to consider are these:
1. Who has access to the data, ie. employees of the cloud service provider.
2. Service continuity – can the data get lost if the provider has a major incident – there have been a surprisingly high number of incidents.
3. Legislation – who can legally gain access to the data.
Key Attributes of Cloud Computing – 3. Operations
9
Somebody else is responsible for all the kit – not (so much) your own people.
This is arguably the biggest point for large organisations, the apparent loss of control. Large organisations have:
Very often invested a great deal of cash in internal infrastructure.
A need to let that investment tail off before considering new initiatives.
Built up internal skills which may be redundant in a cloud environment.
Doubts about letting third parties run core systems in any kind of shared environment.
As a result (public in particular) clouds have, up until now had most success with smaller companies, startups or companies where a specific need exists to store and process large amounts of data periodically, especially media companies.
Does the Cloud Have a Role in Your Organisation?
10
Potentially yes, if:
You are a small organisation with limited IT staff.
You have not invested internally in virtualisation technology.
You have a need to cut costs.
You process large amounts of data infrequently.
You are considering making a significant investment in an infrastructure upgrade.

About VMware
• VMware is the global leader in virtualisation and cloud
infrastructure, based in Palo Alto, CA $3-4b annual turnover
and over 11,000 employees.
13
• VMware delivers customer-
proven solutions that
accelerate IT by reducing
complexity while
significantly lowering costs
and enabling more flexible
and agile service delivery.
About VMware
• VMware’s core virtualisation technology powers 85% of the
worlds virtual machines and today there are VM’s in the
world than physical servers.
• VMware’s breadth of products includes application
development platforms and end users computing solutions
such as Socialcast, Zimbra, Appblast and Octopus.

It’s all in a definition ........
What is Cloud Computing?
15
Cloud is ....
16
Cloud is not a new technology, it’s just a different
approach to delivery.
The Cloud approach enables the shift from in-house
capital intensive IT to the consumption of utility based
computing resource on an as needed basis with an
appropriate pay as you go model.
Cloud computing mimics the delivery of electricity
from the grid, and more recently development in the
mobile market.
The NIST Definition
“Cloud Computing is a model for enabling
ubiquitous, convenient on-demand network access
to a shared pool of configurable IT resources that
can be rapidly provisioned and released with
minimal management effort or service provider
interaction”
• The NIST Definition contains the “magic” 5,4,3.
17
The NIST Definition
• 5 Characteristics
• On-demand, network access, resource pooling,
elasticity, pay as you go.
• 4 deployment models
• Private, Community, Public and Hybrid
• And 3 service models.
• Iaas, Paas, Saas.
