Yes, studies estimate that 30% or more of cloud spend is wasted due to over-provisioning, idle resources, inefficient storage, and lack of cost governance. Many businesses pay for resources they don’t fully utilise, leading to unnecessary expenses.

Which are the cloud cost models?

There are several cloud cost models that businesses can choose from, depending on their needs and usage patterns. The main cloud cost models include:

1. Pay-as-you-go (On-demand): With this model, businesses pay only for the resources they use, such as compute power or storage, on an hourly or per-second basis. It provides flexibility but can lead to unpredictable costs if not monitored properly. This is commonly used by cloud providers like AWS, Azure, and Google Cloud.
2. Reserved Instances: This model involves committing to use specific cloud resources (like virtual machines or storage) for a longer period, typically one or three years, in exchange for significant cost savings. Reserved instances are offered by major providers such as AWS, Google Cloud, and Azure.
3. Spot Instances: These are unused cloud resources that are available at a discounted rate. However, they can be terminated at any time by the provider, making them suitable for non-critical workloads or flexible applications. AWS, Google Cloud, and Azure offer spot instance pricing.
4. Subscription-based: In this model, businesses pay a fixed rate for a set of cloud services over a predefined period. It often comes with a bundle of features or resources at a lower cost than individual on-demand pricing. SaaS providers like Zoho and Microsoft Office 365 typically use this model.
5. Volume-based (Tiered Pricing): Cloud providers offer discounts based on the amount of resources consumed. For example, the more storage or bandwidth a business uses, the lower the cost per unit becomes. AWS and Azure offer tiered pricing for services like storage and data transfer.
6. Hybrid Pricing: A combination of different cost models, this allows businesses to optimise costs by using on-demand resources for variable workloads and reserved or spot instances for predictable workloads. Cloud providers like AWS and Azure support hybrid pricing options.

What is a cost optimization strategy?
