Cloud computing is facilitated often through the open Internet, which is not designed for secure communications. From the cloud user perspective, access to the cloud through a Virtual Private Network (VPN) is a possibility, but this is not the default access method for all cloud users. Given this reality, the cloud service users must be prepared for risk management because they do not control the cloud hardware or the communication channels. Added to this uncertainty is the potential for cloud service outage for risk management planning. In this chapter, the authors discuss the various aspects of risk management from the cloud user perspective. In addition, they analyze some of the major cloud outages over the past five years that have resulted in loss of trust. This list includes the outages in Amazon Web Services, Google, Windows, and Rackspace.

2. Risk Management

Risk is defined as the likelihood that an event will occur that affects the ability to achieve certain goals. With this definition of risk, we can classify the risks as pertaining to system availability, data integrity, system performance and security in general. When a customer uses a cloud service their major risk is with respect to the cloud system availability. In the next section we have addressed some of these aspects to show certain metrics that the customer can evaluate about the service provider’s obligations for system uptime. When the service provider is unable to maintain the level of uptime promised then it leads to multiple risks for the customer. Risk management involves having processes to handle these types of risks.
