10 Persistent Myths on Cloud
Is cloud really the next big step in IT?
The cloud may provide a dynamic and flexible infrastructure, but many are still reluctant to engage this new species. Moreover, many myths persist around the nature of the cloud and how to best interact with the cloud.
Here are 10 viewpoints from experts at Forrester, InfoWorld, TechRepublic, and more sharing some of the most hard to put down myths, and what's really happening.
1. Devs are only using cloud for test & dev.
Evidence has been gathered through case study analysis to refute these rumors - all of which are untrue - but some beliefs just won't die. The leading clouds have matured to the point that there are few legitimate excuses left for not using them.

2. Cloud computing is bringing back vendor lock-in.
The reality is that using any technology, except the most primitive, causes some degree of dependency on that technology or its service provider. Cloud providers are no exception.

3. Clouds provide infinite scale.
For the vast majority of users who are using the public clouds to implement dynamically scaling web sites, the quota allowed is larger than these web sites typically require, thereby providing the illusion of infinite scale. As resource-intensive, highly scalable applications begin to use cloud computing as either a public or on-premise platform, however, they will begin to reach the scaling limits imposed by resource availability.
4. Private cloud is inherently more secure than public cloud services.
A private cloud can be more secure than a public cloud, but like any other system it is at risk from poor housekeeping and human error. Assumptions should not be made. The decision criteria for private or public cloud implementation should be far wider than which is perceived to be more secure.

5. No more IT worries.
People move their servers/applications to a cloud environment (IaaS or PaaS) and think that everything will be magically backed-up and updated regularly and that multiple server copies will be hosted on redundant servers without them having to ever worry about it again. This is not true.

6. You need new hardware to deploy a cloud.
The best cloud solutions can be deployed on your existing X86 hardware - increasing server utilisation and performance. What's more, you can convert old servers into additional compute nodes - increasing your processing capacity.

7. The public cloud is the most inexpensive way to procure IT services.
Delivery from the public cloud is not always the cheapest than that delivered by internal IT. For resources that are needed constantly, enterprises can actually reduce costs by leveraging other cloud models, such as shared resources delivered via a private cloud.

8. Cloud computing will put my job at risk.
In reality, cloud computing won't displace many jobs in enterprise IT, but IT roles and responsibilities will change over time.

9. Transform the organization overnight.
Each organization needs to find its own cloud, and this should be a rigorous, perhaps time-consuming process. Discussion of particular cloud strategies and vendors should come at the end of this process. First, figure out what you want to do and why.

10. Cloud computing gives companies of all sizes the opportunity to quickly scale their IT operations.
Moving to the cloud does present a unique set of challenges for organizations of all sizes. With many IT departments now reporting to the CFO, cost often becomes the key consideration during cloud implementations. When looking for the right cloud technologies, CFOs must focus on long-term productivity and value to their companies.
