Cloud Computing - Is It Right For You?
1. An Introduction to Cloud Computing -Is It Right For You? Carlos Oliveira 13th December 2010
2. What Is Cloud Computing? Making Computing resources available as a utility service, Just like the National Electricity Grid Available through a well-defined interface Available everywhere and for many devices Power output scales to demand No need to know about how or where it’s generated Reliable Low capital expenditure for consumers Pay for what you use
3. On-Premise Computing Requires hardware, space, electricity, cooling Requires managing OS, applications and updates Software Licensing Difficult to scale Too much or too little capacity High upfront capital costs You have complete control and responsibility
4. Managing Demand Forecast demand IT Capacity Potential business loss Compute capacity Over capacity Under capacity Wasted capacity Entry barrier Time
5. Demand Burst IT Demand How do we deal with this? Ticket sales open Ticket sales open Time Concert ticket web site
6. Three Types of Cloud Services “IaaS” “PaaS” “SaaS” Infrastructure as a Service Platform as a Service Software as a Service migrate to it build on it consume it 6
7. Private (On-Premise) Infrastructure (as a Service) Platform (as a Service) Each Brings a Different Level of Control You manage Applications Applications Applications You manage Runtimes Runtimes Runtimes Security & Integration Security & Integration Security & Integration Databases Databases Databases You manage Servers Servers Servers Virtualization Virtualization Virtualization Server HW Server HW Server HW Storage Storage Storage Networking Networking Networking
8. Many Players in the Game To name a few SaaS: Microsoft, Salesforce, Zimra, Oracle, Cisco, Google Apps PaaS: Microsoft, Force.com, Spring Source, Google App Engine IaaS: Amazon, IBM, VMware, Microsoft Expect change, the cloud is still in it’s infancy In the future expect to see large vendors offering all of the services
9. What We Get With SaaS Lower capital expenditure Fixed operational costs Scalability Reclaimed office space Innovation Lower carbon footprint Agility
10. What To Watch You are relinquishing control and responsibility to the vendor by moving the service to the Cloud For 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
11. What We Get With PaaS An elastic computing platform Connect from anywhere, with any device Low barrier costs to deploying new applications Rapid provisioning Pay 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 theservices No chance of licence abuse

13. What to Watch Check your security policies can be satisfied by the Cloud provider Does 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
14. “Cloud Computing and Sustainability” 30-90% FEWER CO2 EMISSIONS* MORE EFFICIENT IT Dynamic provisioning Multi-tenancy Server utilization Data center design Reduced energy bills Fewer servers Less datacenter space Less expensive 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 * Cloud Computing and Sustainability: The Environmental Benefits of Moving to the Cloud; www.microsoft.com/environment/cloud.aspx
16. Reframe your thinking Use the best of breed Stop thinking about applicationsrunning on servers CRM Ordering Invoicing Invoicing Ordering CRM Think of them as pay on demandservices Communications Business forecasting Rapidly add and try new functionality Social Networking
17. Should YouMove 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.”
