In cloud computing, what is a primary advantage enabling handling variable workloads?

• A. Cost efficiency
• B. Security
• C. Scalability
• D. Reliability

Answer: (C)

Scalability means the ability to grow or shrink resources to match changing demand. When workloads vary, scalable cloud systems can automatically add or remove compute, storage, and networking resources so performance stays consistent without overprovisioning. This dynamic adjustment is achieved through techniques like auto-scaling and container orchestration, which respond to real-time load. While cost efficiency, security, and reliability are important, they don’t directly enable handling variable workloads as effectively—scalability specifically provides the flexible capacity needed to meet fluctuating demand.
