1. Myth: Cloud is just a fad
Truth: Cloud as a term is new, but the concepts and requisite technologies have been evolving for years (many years in some cases). Cloud computing continues to emerge as a disruptive technology, with high adoption rates and investment. Gartner predicts that by 2012, 80 percent of Fortune 1000 enterprises will be paying for some form of cloud computing services. Cloud is here to stay.
2. Myth: The Cloud is not secure
Truth: Public clouds are fundamentally multi-tenant to justify the scale and economics of the cloud. As such, security is a common concern. Whereas the traditional security perimeter is a network firewall, the cloud security perimeter now becomes the hypervisor and/or underlying cloud application. Thus far, security in the cloud has been good, but this is very cloud dependent and requires a solid design and operational rigor that prioritizes security. Also, handing your data and systems to someone else requires proper internal controls to ensure that not just anyone has access. Be sure to ask potential cloud providers about security from technical, operational, and control perspectives, as well as what experience they have being stewards of customer systems and data. If the public cloud is fundamentally not secure enough, consider an on-premise cloud, virtual private cloud, or some sort of hybrid cloud solution (see Truth #10) that allows you to maintain the level of security you require.
3. Myth: The cloud is not reliable
Truth: No system has 100% uptime all the time, and neither does the cloud. Given the scale, however, cloud services are typically designed to provide high redundancy and availability. While this same level of redundancy/availability is possible to achieve in-house or with dedicated hosting, it’s generally cost prohibitive except for the most critical systems. The cloud enables a higher level of reliability at a fraction of the cost.
