Coud discovery chap 6

  1. 1. CLOUD DISCOVERY AN INTRODUCTION TO CLOUD COMPUTINGChapter 6: Planning for the Cloud By: Alain Charpentier
  2. 2. Table of content• Technical consideration – What application to move to the Cloud, Security considerations, Compliance considerations, Performance considerations, Migration considerations• External Business consideration – What about sunk cost?, Vendor lock-in• Internal Business consideration – Shifting IT responsibilities, Objections
  3. 3. The driver of the Cloud revolution• Virtualization – The ability to increase computing efficiency• Democratization of Computing – Bringing enterprise scale infrastructure to small and medium businesses• Scalability and fast provisioning – Bringing web scale IT at a rapid pace• Commoditization of infrastructure – Enabling IT to focus on the strategic aspects of its role
  4. 4. What application to moveApplications that have significantinteraction with external applications orservices UniqueApplicable Difficult toto many replicate Applications that are not a point ofsituations differentiation between the Competitive organization and its competitors advantage Superior to the Sustainable competition
  5. 5. Security & Compliance• Organizations should be aware that security is a partnership between the vendor and the user. They should therefore clearly ascertain which aspects of security are the responsibility of the vendor and which are the responsibility of the user.• Depending on the type of industry your organization is involved in, there are a number of different compliance requirements which may need to be met. Examples of these include PCI, HIPAA, GAAP, SOX, and IFRS.
  6. 6. Performance & Migration• Performance – It is importantly to accurately assess the performance requirements. For example an application with high database transfer rates, very high CPU or RAM requirements may be either difficult, or cost prohibitive, to move to the Cloud.• Migration – The bandwidth cost of moving significant amounts of data to the Cloud – The time taken to transfer data in the migration process – In the case of an application, the business process involved in a migration (downtime, business continuity, training etc.)
  7. 7. Architecting for the CloudTraditional Web applicationsarchitecture do not rapidly scale andare not has redundant has Cloudapplication. Traditional applications may need to be re-architected to fully benefit from the capabilities offered by the Cloud
  8. 8. External Business Consideration• Sunk cost – It may make sense for organizations to look to a gradual move to the Cloud. For an example, where existing applications and infrastructure are being well utilized, an approach that sees excess capacity delivered from the Cloud can be seen as appropriate.• Planning for variability – The rapid scaling and the on-demand pricing model of the Cloud can bring great business benefits but new skills may need to be develop within IT to effectively manage the Cloud.• Vendor lock-in – Cloud Computing provider tends to be much more transparent when it comes to lock in and so organizations should be able to accurately gauge the risks.
  9. 9. Internal Business Consideration• Shifting IT responsibilities – As with previous technological shifts, we believe this change in IT responsibilities actually provides opportunities for IT staff. While Cloud Computing certainly limits the opportunities for some skills, it offers up some new ones in the areas of Cloud management, application customization and agile development• Formal qualification – There is a distinct lack of formal Cloud Computing qualifications. Whereas IT staff can choose from a plethora of formal, specialist training for traditional IT, in the Cloud world this is not the case. While this is not surprising given the relative newness of the Cloud, nonetheless end users feel uncomfortable with the lack of certification
