What enables high availability in a Splunk Cloud setup?

High availability in a Splunk Cloud setup is primarily enabled by the geographical distribution of data centers. This feature ensures that the Splunk infrastructure is designed to withstand failures or disruptions by having multiple data centers across different geographical locations. If one data center goes down or experiences issues, the system can continue to operate from another data center, providing seamless access to the data and maintaining service continuity.

Geographical distribution allows for redundancy and ensures that data is replicated and available across various locations. This is crucial for disaster recovery and for meeting the needs of users who may be accessing the system from different regions, thereby minimizing latency and improving performance.

The other options, while relevant in certain contexts, do not directly contribute to the high availability aspect in the same way. The size of the deployment can influence capacity and performance but is not the primary factor for ensuring high availability. Virtual machine flexibility focuses on resource allocation rather than availability itself, while cloud-based applications pertain more to the software architecture and deployment rather than the inherent availability strategies employed in a distributed cloud environment.
