The primary advantage of cloud computing mentioned in the text is lower cost. Cloud computing refers to the delivery of computing services, including servers, storage, databases, networking, software, analytics, and intelligence, over the internet. It allows individuals and businesses to access computing resources on-demand without the need for investing in and maintaining physical infrastructure.

Lower Cost:
Cloud computing offers several cost-saving benefits, making it a popular choice for individuals and businesses alike.

1. No upfront capital investment: With cloud computing, there is no need to invest in expensive hardware and software infrastructure. Instead, users can pay for computing resources on a pay-as-you-go basis, which significantly reduces upfront costs.

2. Reduced operational costs: Cloud computing eliminates the need for maintaining and managing physical servers, which can be expensive. By leveraging cloud service providers, businesses can save on costs associated with hardware maintenance, software updates, security measures, and energy consumption.

3. Scalable pricing models: Cloud services typically offer flexible pricing models that allow users to scale their resources up or down based on their needs. This eliminates the need to over-provision resources, ensuring that businesses only pay for what they actually use.

4. Economies of scale: Cloud service providers operate massive data centers and can achieve economies of scale by serving a large number of customers. This enables them to offer services at a lower cost compared to individual businesses setting up their own infrastructure.

5. Reduced personnel costs: With cloud computing, businesses can rely on the expertise of cloud service providers for managing and maintaining the infrastructure. This eliminates the need for in-house IT staff dedicated to infrastructure management, resulting in cost savings.

By leveraging the cost-saving advantages of cloud computing, businesses can allocate their resources more efficiently, invest in innovation, and focus on their core competencies. Additionally, individuals can benefit from lower costs when using cloud-based applications and services for personal use.
