What is the biggest challenge for companies to implement disaster preparedness in a cloud environment? The biggest challenge of disaster preparedness deployment in a cloud environment is the security of data stored in a cloud environment, especially in storage solutions provided by third parties. Since many customers and their data are usually kept in the cloud, a system that provides cloud services can be compromised, potentially impacting many customers. In this way, cloud service providers should ensure the security of the cloud environment they provide, for example, they should encrypt all customer data, and should deploy sophisticated profiling tools to identify potential threats (such as distributed denial of service attacks) ...
