Which aspect of security is demonstrated by deploying multiple instances of an application to geo-dispersed locations?

1. Integrity

2. Availability

3. Confidentiality

4. Accountability

The correct answer is: Availability

Deploying multiple instances of an application to geo-dispersed locations primarily enhances the aspect of availability in security. Availability ensures that applications and services are consistently operational and accessible to users, even in the event of an outage or a failure in a particular geographic location. By distributing instances across various locations, the application can maintain functionality if one region experiences a failure, natural disaster, or another issue that affects access. This geo-dispersed approach allows for load balancing as well, mitigating potential bottlenecks and ensuring that users can connect to the application from a location that is less affected or still functioning, thereby improving overall uptime and reliability. While integrity, confidentiality, and accountability are also important facets of security, they do not directly relate to the practice of deploying applications across multiple geographical areas to ensure continuous accessibility. Integrity pertains to data accuracy and consistency, confidentiality involves protecting data from unauthorized access, and accountability relates to tracking user actions and ensuring compliance with policies. None of these objectives directly address the continuous availability of services, which is a critical requirement for many applications in modern cloud environments.
