Several premier cloud computing Service Providers have suffered disruptions in the past year – affecting millions of users. There are cases where a small number of users lose the capabilities of a particular service offering while the remaining users retain full functionality. For example, some Gmail disruptions have affected only a small percentage of the user base. In other cases, outages may take out a number of customer websites that rely on those services. When Amazon Web Services' (AWS) cloud computing infrastructure experienced a brief network outage, it knocked offline popular sites such as Foursquare, Heroku, Quora, Reddit, and Netflix that rely on the underlying AWS functionality. For private cloud-based services, any disruptions at the cloud Service Provider level can be just as traumatic.

Security and privacy concerns continue to lead U.S. federal department CIOs to choose private clouds over public clouds. For large Federal departments and their sub-agencies, private clouds can be ideal because they provide security and privacy while still yielding performance and efficiency gains. When it comes to the cloud, however, size matters. Smaller U.S. federal agencies and state and local governments may fail to achieve the economies of scale necessary for benefiting from a private cloud environment. For this reason, smaller public sector organizations with interconnected missions should consider following the German example and invest in a third type of cloud solution: the community cloud.
