The cloud offers various pricing models to accommodate different business requirements. The most prevalent among them are:
a. Pay-as-you-go: Users pay only for the resources they consume, cloud computing cost allowing for scalability and flexibility.
b. Reserved instances: Customers commit to using specific resources for a fixed term, usually at a discounted rate.
c. Spot instances: Organizations bid for unused and excess capacity, often securing computing power at significantly reduced prices.
