Explanation:
If an organization wants to use a cloud service for BCDR, the location of the cloud hosting becomes a very important security consideration due to regulations and jurisdiction, which could be dramatically different from the organization's normal hosting locations. Availability is a hallmark of any cloud service provider, and likely will not be a prime consideration when an organization is considering using a cloud for BCDR; the same goes for self-service options. Resource pooling is common among all cloud systems and would not be a concern when an organization is dealing with the provisioning of resources during a disaster.

Explanation
When a cloud service provider receives an eDiscovery order pertaining to one of their customers, the first action they must take is to notify the customer. This allows the customer to be aware of what was received, as well as to conduct a review to determine if any challenges are necessary or warranted. Taking snapshots of virtual machines, copying data, and escrowing encryption keys are all processes involved in the actual collection of data and should not be performed until the customer has been notified of the request.

Explanation
Any application can be a possible target of denial-of-service (DoS) attacks. From the application side, the developers should minimize how many operations are performed for non-authenticated users. This will keep the application running as quickly as possible and using the least amount of system resources to help minimize the impact of any such attacks.
