A customer who is running cloud-native applications using an IaaS provider wants to consider business continuity in case of failure. Which of the following should be done to ensure the LEAST amount of

Failing over to another region within the same IaaS provider minimizes the amount of changes because the underlying cloud services, APIs, and tools remain consistent across regions. This approach also helps avoid data governance issues as data typically stays within the same provider's legal and compliance framework, often with clear data residency options for regional data centers.

Failing over to another zone within the same region provides resilience against zone-specific failures but does not protect against region-wide outages, which is a broader business continuity concern.

Failing over to a cold site location typically involves significant changes to infrastructure, networking, and application configuration, leading to a much higher Recovery Time Objective (RTO) and Recovery Point Objective (RPO) than an active-active or active-passive regional setup.

Failing over to another cloud provider (multi-cloud DR) introduces substantial changes due to differing APIs, services, networking, and governance models, making it complex and expensive to implement and maintain.
