Similarities and Differences between Cloud Computing and Outsourcing
https://www.youtube.com/watch?v=Qw_3EOp6fvM
189
Scalability
| Cloud Services from a Business Perspective
Cloud computing allows for immediate scaling at any time, without long-term commitment. More CPU, more memory, more storage the horsepower when you need it.
190
Security
| Cloud Services from a Business Perspective
Security is one of the biggest concerns of this computing model. With security becoming a core factor for organizations determining a cloud provider, many cloud vendors are emphasizing security from the get-go. The large scale of cloud helps providers hire skilled professionals to input the latest and best in measures and governance around the security, privacy, and confidentiality of your infrastructure and services.
191
Hardware Independence
| Cloud Services from a Business Perspective
Cloud computing is hardware agnostic, providing a convenient way of accessing computing services, independent of the hardware you use. This model provides a high degree of flexibility and openness versus being boxed into specific hardware platforms that may not adapt to changes over time.
192
Variable Costs
| Cloud Services from a Business Perspective
One of the factors that appeals to consumers of cloud computing services is the benefit of variable costs. With a variable cost basis, organizations can take more risks. If cloud computing doesn't work out, they can close the relationship/unsubscribe from the service at any time. It's a lot less risky than investing in capital and acquiring infrastructure or licenses and having to keep them when they are no longer needed.
193
Time to Market
| Cloud Services from a Business Perspective
Most businesses are faced with enormous pressure to accelerate time-to-market for new products and services while controlling costs. In many organizations, IT staff are so busy maintaining critical production systems that setting up development, test, and QA servers fall behind. Cloud computing provides a rapid deployment model that enables applications to be set up in record time at a low cost. It makes resource provisioning dynamic and a self-service system, where application development teams can now provision their own servers; even if the infrastructure team does it for them, it can still be done at a fraction of the time and cost of traditional models.
194
Distribution over the Internet
| Cloud Services from a Business Perspective
The Internet is one of the most reliable components of computing infrastructure. Your Internet provider may occasionally have hiccups, but when compared to the rates of failures for disk drives, memory, cooling units, backup power, etc., in your internal data center, the uptime for the Internet is considerably higher. In addition to uptime, the method of providing the computing resources via the Internet is, by itself, a major time- and costs-saving benefit.
195
Steps to Successful Adoption of Cloud Computing
- Identify your business drivers: Get educated, talk to vendors and key members of your IT staff
- Develop the strategy: Show how the cloud can align with business needs, and articulate a value proposition
- To cloud or not?: Assess your organizational readiness from financial, technical, business and governance perspectives
- Pilot it: Run a pilot with one or more scenarios where you anticipate benefits. Evaluate against clearly defined success criteria
- Gain stakeholder buy-in: Carefully analyze feedback from both IT staff, as well as users. Is cloud computing right for your organization? Is it worth it? Get buy-in
- Plan for an enterprise roll-out: If the pilot is successful
