Which of the following should a cloud architect consider for a containerized cluster in a cloud environment?

Regional area is a general infrastructure placement concern, not a consideration specific to containerized cluster design.

Cloud bursting is a hybrid-cloud capacity overflow strategy, not a primary architectural consideration for a containerized cluster itself.

Lower costs are a potential benefit of containerization but are an outcome of good design decisions, not an architectural consideration to plan for.

Scalability is the defining architectural advantage of containerized clusters - orchestration platforms like Kubernetes are purpose-built to scale workloads up and down dynamically based on demand. Designing for scalability ensures the cluster can handle variable loads efficiently and is the core reason organizations adopt container orchestration in cloud environments.
