  • 3. Moving to the CloudReasons to MoveBenefits: Virtualization – The ability to increase computing efficiency Democratization of Computing – Bringing enterprise scaleinfrastructure to small and medium businesses Scalability and fast provisioning – Bringing web scale IT ata rapid pace Commoditization of infrastructure – Enabling IT to focus onthe strategic aspects of its role
  • 4. Moving to the CloudTechnical Considerations (1/7)1. Which applications?The prime candidates to move are:• Have significant interaction withexternal applications or services• Are not a point of differentiationbetween the organization and itscompetitors
  • 5. Moving to the CloudTechnical Considerations (2/7)2. Security ConsiderationsOrganizations should be aware that security is apartnership between the vendor and the user.Must be a clear definition:Which aspects of security are the responsibility of the Vendorand which are the responsibility of the User.
  • 6. Moving to the CloudTechnical Considerations (3/7)2. Security Considerations (Cont.)
  • 7. Moving to the CloudTechnical Considerations (4/7)3. Compliance ConsiderationsDepending on the type of industry, there are a number ofdifferent compliance requirements which may need to bemet.Examples of these include:PCI: Payment Card Industry Data Security StandardHIPAA: Health Insurance Portability and Accountability ActGAAP: Generally Accepted Accounting Principles (USA)SOX: Sarbanes-Oxley Act of 2002IFRS: International Financial Reporting Standards
  • 8. Moving to the CloudTechnical Considerations (5/7)4. Performance ConsiderationsIt is important to accurately assess the performancerequirements the organization may have.In particular for applications with: High database transfer rates Very high CPU or RAM requirementsMay be either difficult, or cost prohibitive, to move to theCloud.
  • 9. Moving to the CloudTechnical Considerations (6/7)5. Migration StrategyCost and time it takes to move an existing workload to theCloud.Specific topics: The bandwidth cost of moving significant amounts of datato the Cloud The time taken to transfer data in the migration process In the case of an application, the business processinvolved in a migration (downtime, businesscontinuity, training etc.)
  • 10. Moving to the CloudTechnical Considerations (7/7)6. Architecting for the CloudTo realize Cloud Computing benefits, the applications needto be architected to take advantage of the scalable nature ofCloud Computing. Legacy applications may not be able to truly leverageCloud benefits, without significant re-architecting. New applications, should be built with this in mind.
  • 11. Moving to the CloudInternal Business Considerations1. Planning for Shifting IT Responsibilities2. Lack of Formal Certifications3. Dealing with ObjectionsA move to the Cloud changes the face of corporate IT.Recommendations: A proactive approach to professional development andtraining. Motivate personnel to explore new areas as: applicationcustomization and agile development.
  • 12. Moving to the CloudExternal Business Considerations (1/3)1. Dealing with Sunk CostConsidering previous capital expenditure:New applications or excess capacity delivered from theCloud can be seen as appropriate.2. Costs and Planning for VariabilityWith proper controls, when compute resources are beingused, they are adding value, unlike traditional ITinvestments that continue to be amortized even if sittingidle.
  • 13. Moving to the CloudExternal Business Considerations (2/3)3. Vendor Lock-inOrganizations should look at a number of differentfactors: Does the vendor use industry standard APIs or proprietaryones? Does the vendor provide quick and easy data extraction inthe event that the customer wishes to shift? Does the vendor use open standards or have they createdtheir own ways of doing things? Can the Cloud Computing service be controlled by thirdparty control panels?
  • 14. Moving to the CloudExternal Business Considerations (3/3)4. Choosing a Vendor Billing capabilities – Flexible billing to meet variability. Fixed costs – Should be variable and related to usage Minimum charges – Avoid vendors who seek to set aminimum charge for compute or storage as it impactsupon the flexibility of the offering Performance – Service Level Agreements andperformance dashboards should give users certaintyand transparency over the availability and performanceof their vendor Support – A vendor who provides high levels of supportmay prove a significant benefit and simplify a move tothe Cloud.
