A company needs services to remain available even if a data center fails. What should they implement?

High availability ensures that services remain operational even during failures, such as a data center outage, by distributing resources across multiple fault domains or regions. This minimizes downtime and maintains business continuity. Multi-tenancy refers to a single instance of a software application serving multiple customers, which doesn't directly address data center failures. Vertical scaling (scaling up) involves increasing the resources of a single server, which makes it a single point of failure and doesn't protect against a data center outage. Cold storage is for archiving infrequently accessed data and does not provide immediate service availability.
