An Introduction to Cloud Computing -Is It Right For You?Carlos Oliveira13th December 2010
What Is Cloud Computing?
Making Computing resources available as a utility service,
Just like the National Electricity GridAvailable through a well-defined interfaceAvailable everywhere and for many devicesPower output scales to demandNo need to know about how or where it’s generatedReliableLow capital expenditure for consumersPay for what you use
On-Premise Computing
Requires hardware, space, electricity, coolingRequires managing OS, applications and updatesSoftware LicensingDifficult to scale
Too much or too little capacity
High upfront capital costsYou have complete control and responsibility
Managing Demand
Time
IT Capacity
Entrybarrier
Under capacity
Over capacity
Forecast demand
Potential business loss
Wasted capacity
Compute capacity
Demand Burst
Time
IT Demand

How do we deal with this?
Three Types of Cloud Services
6
“IaaS”Infrastructure as a Service
migrate to it
“PaaS”Platform as a Service
build on it
“SaaS”Software as a Service
consume it
Private(On-Premise)

Many Players in the Game
To name a fewSaaS: Microsoft, Salesforce, Zimra, Oracle, Cisco, Google AppsPaaS: Microsoft, Force.com, Spring Source, Google App EngineIaaS: Amazon, IBM, VMware, Microsoft
Expect change, the cloud is still in it’s infancyIn the future expect to see large vendors offering all of the services
What We Get With SaaS
Lower capital expenditureFixed operational costsScalabilityReclaimed office spaceInnovationLower carbon footprintAgility
What To WatchYou are relinquishing control and responsibility to the vendor by moving the service to the CloudFor this to be a valid business proposition you must trust the vendor to deliver what they say they will
Financial penalties for failing to meet SLA are normally equated to service credits
Many solutions appear attractive because of the bottom line pay/user price
They may exceed or fall short of your business requirements
What We Get With PaaS
An elastic computing platformConnect from anywhere, with any deviceLow barrier costs to deploying new applications
Rapid provisioningPay as you go
Operational costs directly related to profit
A marketplace through which to sell services
Customers continue to pay as long as they use the servicesNo chance of licence abuse

Scale prior todemand
What to WatchCheck your security policies can be satisfied by the Cloud providerDoes the SLA meet availability requirements?Don’t just port an existing app that have been sitting within your security perimeter
Make sure it has been engineered for Internet security
Follow Security Development Lifecycle (SDL) best practices
“Cloud Computing and Sustainability”
ONLINE SERVICES SUPPORTS OUR AMBITION TO BE ENVIRONMENTALLY CONSCIOUS BY ENABLING US TO OPERATE WITH FEWER SERVERS AND LESS ENERGY CONSUMPTION, ELIMINATING APPROXIMATELY 800 METRIC TONS OF CARBON DIOXIDE A YEAR,” -PIA HOFSTEDT, DIRECTOR OF IT, SCANDIC
Reduced energy bills
Fewer servers
Less datacenter space
Less expensive
MORE EFFICIENT IT
Dynamic provisioning
Multi-tenancy
Server utilization
Data center design
30-90% FEWER CO2 EMISSIONS*

Companies Are Embracing Cloud
Reframe your thinking

Think of them as pay on demandservices
Use the best of breed
Communications
Social Networking
Business forecasting
Rapidly add and try new functionality
Should You Move To The Cloud?
Can you afford not to?
“By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% of businesses will own no IT assets.”
“The bottom line: Early adopters are finding serious benefits, meaning that cloud computing is real and warrants your scrutiny as a new set of platforms for business applications.”
So...What Is Cloud Computing?
It’s a utility,providing us with:
• New ways of working• Reduced IT costs• New opportunities
