The article discusses the concept of metered billing, which allows businesses to pay for actual cloud usage, enhancing cost control and IT efficiency. It explains that metering is essential for tracking cloud usage, with robust control planes and API-enabled infrastructure being key for accurate data. The benefits of metered billing include cost savings, better budget predictability, resource optimization, scalability, and transparency. However, pitfalls such as over-provisioning and user errors can lead to unexpected costs. To optimize IaaS pricing, businesses should consider factors like fluctuating usage patterns, leveraging higher pricing tiers, provisioning bandwidth for resource fluctuations, and customizing resource requirements.
