What factor(s), if any, allows for more efficient and effective containment and recovery in a cloud environment than in a non-cloud environment.
Virtualization technologies and the elasticity inherent in cloud computing platforms allow for more efficient and effective containment and recovery. These technologies enable rapid scaling, flexible infrastructure management, and quick isolation of issues, making it easier to respond to incidents and restore services in a cloud environment compared to a non-cloud environment.
pg: 106 The cloud often provides a lot more flexibility in this phase of the response, especially for IaaS. Software-defined infrastructure allows you to quickly rebuild from scratch in a clean environment, and, for more isolated attacks, inherent cloud characteristics—such as auto-scale groups, API calls for changing virtual network or machine configurations, and snapshots—can speed quarantine, eradication, and recovery processes. For example, on many platforms you can instantly quarantine virtual machines by moving the instance out of the auto-scale group, isolating it with virtual firewalls, and replacing it.
