What is the primary purpose of using multiple environments (e.

The primary reason for implementing multiple environments in cloud native platforms is to isolate the different phases of the software development lifecycle. Option A is correct because environments such as development, staging, and production enable testing and validation at each stage without impacting end users. Development environments allow rapid iteration, staging environments simulate production for integration and performance testing, and production environments serve real users.

Option B (reducing costs) may be a side effect but is not the main purpose. Option C (distributing traffic) relates more to load balancing and high availability, not environment separation. Option D is the opposite of the goal—different environments often require tailored infrastructure to meet their distinct purposes.

Isolation through multiple environments is fundamental to reducing risk, supporting continuous delivery, and ensuring stability. This practice also allows for compliance checks, automated testing, and user acceptance validation before changes reach production.
