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.

Explanation
Public clouds, such as AWS and Azure, are massive systems run by major corporations, and they account for a significant share of Internet traffic and services. They are always expanding, offer enormous resources to customers, and are the least likely to run into resource constraints compared to the other deployment models.
Private clouds would likely have the resources available for specific uses and could not be assumed to have a large pool of resources available for expansion. A community cloud would have the same issues as a private cloud, being targeted to similar organizations. A hybrid cloud, because it spans multiple clouds, would not fit the bill either, without the use of individual cloud models.

Explanation
The infrastructure service capability gives the cloud customer substantial control in provisioning and configuring resources, including processing, storage, and network resources.
