The document discusses the critical considerations for CXOs when developing a cloud migration strategy, emphasizing four key areas: the relationship between cloud computing and business, financial implications, operational issues, and the choices available. It highlights the importance of minimizing disruption during migration, ensuring data security, compliance, and maintaining existing infrastructure performance. The recommended approach is to adopt a virtual data center model to facilitate an effective transition without extensive changes to current operations.
Cloud Migration Strategy
- 1. Cloud Migration A CXO’s Strategy for Getting it Right
- 2. The most argued topic in a board room of any size is the role of Cloud computing in the success of their business. The topic is multi-dimensional. CXO’s need to equip themselves with the right information and provide answers to their board. Cloud Computing: The Most Argued Topic
- 3. CXO’s Need to Provide Answers Following are 4 important topics that need to be addressed…
- 4. 1. Relationship Between Cloud Computing and our Business 4. Choice and Flexibility 3. Operational Issues 2. Financial Implications of Being in the Cloud Four Important Topics a CXO Must Address:
- 5. • Are we users or providers of Cloud-based products & Services? • What is the nature of information stored in the Cloud? Is it sensitive or public record? • Who owns the data stored in the Cloud? We? Customers? Some other 3rd Party? • Is our data secure enough wishing the Cloud as promised by the Cloud service providers? • Are we fulfilling our compliance commitments by keeping our data in the Cloud? 1. Relationship Between Cloud Computing and our Business
- 6. • Should we move to the Cloud for the range of additional benefits that will accrue even if it is costlier? • Should we look for specific cost gains in choosing to move to the Cloud? • What kind of incremental investment and regular cash outflow is needed to support our Cloud strategy 2. Financial Implications of Being in the Cloud
- 7. • What does our typical workload and peak workload look like? • Do we need to provide for sudden bursts in our computing power for short durations? 3. Operational Issues
- 8. • Are we likely to get locked-in with the Cloud Infrastructure Services Provider and become dependent on them? 4. Choice and Flexibility
- 9. How easy is it to migrate existing applications and IT infrastructure to the Cloud? Most Important Tactical Question
- 10. CXO’s Migration Strategy - Must Ensure that: • Business operations are not impacted by moving to the Cloud • Minimal or no code changes in existing applications • Seamless transition of existing security architecture in the Cloud model • Effortless integration with currently deployed network architecture • Same or better I/O performance • Compute node configurations match currently deployed servers • Application performance in not impacted • Speed of migration (or the lack of it) does not act as a deterrent to Cloud computing
- 11. Many businesses and their IT departments make the mistake of mixing up moving to the Cloud and moving their dev teams to DevOps culture and re-think their architecture. Though a good end- goal, you don’t need to tackle from the get-go. Moving to Cloud-based infrastructure should not force you to re- think your existing architecture.

- 12. CXO’s Migration Strategy - Choose the Right IaaS If you choose the right Infrastructure as a Service model to migrate to, you will not upset the rhythm of day-to-day business and that of your existing teams. And, deploying to the Cloud will not turn into an exercise of re- thinking your IT philosophy. Here’s how to think about it…
- 13. CXO’s Migration Strategy - Data Center Model In a typical corporate Data Center, you would find: • Centralization of your organization’s IT operations & equipment • Ability to deploy multiple servers and storage devices of varying configurations to support business-critical applications • Switches, routers, and cables to configure physical networks to enable separation of rolls and responsibility requirements set out by your auditors • Firewalls, IPS and IDS to implement security zones. • Trained staff to monitor and maintain deployed infrastructure
- 14. CXO’s Migration Strategy - virtual Data Center For a smooth transition, migrate to a virtual Data Center. A rightly designed vDC offers all the features provided by its physical counterpart: • Provision virtual compute, storage, networking and security resources on demand • Configure networks to enable communication between deployed resources with vDC • Implement security and access restrictions • Administrative management of vDC in totality or in parts • Monitoring & Alerting for provisioned virtual resources • Access to audit logs to meet compliance requirements set forth
- 15. CXO’s Migration Strategy - virtual Data Center For anyone considering migration from their existing data center to Cloud, or thinking of consolidating various, already deployed virtual machines in an existing Cloud into a single, manageable, secure Cloud construct, virtual Data Center (vDC) is the way to go. It’s almost as easy as picking up Lego pieces from one table to rebuild on another – just-in-place replacement.
