Copyright © 2012 EMC Corporation. All Rights Reserved. • Tier 2 -4: private cloud • Tier 1: may continue to run in a traditional data center environment Module 13: Cloud Computing 37

Choosing Applications for Public Cloud • Some key questions to ask before migrating a consumer application to the public cloud: 4 Is the application compatible to cloud platform software? Is it a legacy application? 4 Is the application proprietary and mission-critical? Does the application provide competitive advantage? 4 Is the application workload network traffic intensive? Will application performance be impacted by network latency and limited network bandwidth? 4 Does the application communicate with other data center resources or applications? EMC Proven Professional. Copyright © 2012 EMC Corporation. All Rights Reserved. Module 13: Cloud Computing 38

Financial Advantage • Require analysis of financial benefits in adopting cloud • Consider capital expenditure (CAPEX) and operation expenditure (OPEX) to deploy and maintain own infrastructure versus cloudadoption cost Cost of Owning Infrastructure Cloud Adoption Cost CAPEX OPEX • Servers • Storage • Operating system (OS) • Application • Network equipments • Real estate • • Migration • Compliance and security • Subscription fee Power and cooling Personnel Bandwidth Maintenance Support Backup EMC Proven Professional.

Selecting a Public Cloud Service Provider • Some key questions to ask before selecting a provider: 4 How long and how well has the provider been delivering the services? 4 How well does the provider meet the organization’s current and future requirements? 4 How easy is it to add or remove services? 4 How easy is it to move to another provider, when required? 4 What happens when the provider upgrades their software? Is it forced on everyone? Can you upgrade on your own schedule? 4 Does the provider offer the required security services? 4 Does the provider meet your legal and privacy requirements? 4 Does the provider have good customer service support?
