When companies move their applications to the cloud, they need to update their Disaster Recovery Plan. The biggest reason for this is that, in the cloud, there is an increased reliance on independent service providers, or vendors. To do the update, the company needs to assemble and review all the contracts with the vendors. They also need to obtain and review all the Service Level Agreements (SLAs) with those vendors. SLAs deal with such issues as performance, uptime, service response, including any penalties against the vendor for service failures.
The vendors provide security and privacy for the data, which needs to be reviewed. Often audit reports are essential to achieve the necessary level of reliance.
