Final answer:
The specific cloud computing feature that helps businesses serve their customers without service interruption and in a cost-effective way is high availability.
Step-by-step explanation:
High availability in cloud computing ensures that services and applications remain accessible and operational with minimal downtime. It involves redundant infrastructure, data replication across multiple locations, and automatic failover mechanisms. This feature allows businesses to maintain continuous operations even if one part of the system fails.
By leveraging high availability, companies can ensure uninterrupted service delivery to their customers, thereby enhancing reliability and customer satisfaction. Additionally, this feature contributes to cost-effectiveness by reducing the potential losses incurred from downtime. Instead of investing in expensive infrastructure redundancies on-premises, businesses can rely on the cloud provider's infrastructure, paying for the resources used while benefiting from the assurance of continuous service availability.
Ultimately, high availability is a cornerstone of robust cloud infrastructure, enabling businesses to deliver uninterrupted services to customers efficiently and economically.
