Cloud services have become a dominant force in the software industry over the past decade. Cloud computing offers a paradigm shift in data storage and application management by enabling scalability, accessibility, and cost-effectiveness. In today's data-driven world, secure and accessible storage is vital. Once the data is stored in a cloud environment, the businesses are entitled to avail several benefits such as faster information deployment, better collaboration, disaster recovery, and less requirement of management and supervision.

As enterprises expand and augment their cloud services, understanding the various Cloud Pricing Models is imperative to ensure that they invest in the one that best aligns with their specific requirements. Proper comprehension of these models can significantly reduce the risk of overspending or underutilization of cloud resources. Thus, it is essential to carefully evaluate the pricing models offered by cloud service providers before making a decision.

Importance of Cloud Pricing Model

Cloud pricing models are the foundation of your cloud spending. They determine your cloud expenses and have a significant impact on your business's ability to adapt swiftly to changing business requirements and maintain a cost-effective approach.

By selecting the right cloud pricing model, businesses achieve a trifecta of efficiency, agility, and transparency. If you are going for AWS, cloud pricing models offer a powerful toolset for AWS cloud cost optimization. As you recognize the significance of cloud pricing models, it’s essential to explore how each model operates and determine the best fit for specific business requirements.

Types of Cloud Pricing Models in Cloud Computing

As businesses and startups increasingly embrace cloud, understanding the intricacies of cloud pricing models becomes paramount.

For organizations that prioritize AWS cost savings, the following guide can be used to effectively determine the most suitable strategy for the business. By following this guide, you can ensure that your business optimizes its use of AWS while minimizing costs.

1. Pay-As-You-Go (PAYG) Cloud Pricing Model

The Pay-As-You-Go model charges the business based on actual usage. With this cloud pricing model, organizations can scale resources up or down instantly to meet changing needs without any upfront costs or long-term commitments.

Pros - This model eliminates the risk of overpaying for unused resources and is useful for short-term or experimental projects.
No need for large investments, you only pay for what you use.

Cons - Changing usage patterns can lead to significant cost fluctuations. It can be tough for businesses to keep track of resource scaling, and they may not even realize it's happening until the monthly bill arrives. 

Suitable for - This cloud pricing model is suitable for businesses with fluctuating needs. It allows them to adapt quickly to growth or dynamic business demands.

2. Subscription-Based Cloud Pricing Model

A fixed number of cloud resources are provided in this cloud pricing model for a predetermined monthly or yearly fee. Businesses can choose a suitable package that aligns with their needs at a predictable cost regardless of actual usage. This model is equivalent to a Netflix for cloud - you pay a flat fee for a pre-defined resource package.

Pros - Fixed costs ensure predictable cloud expenses, simplifying financial planning for your business. This skips the need to have a dedicated team with expertise in predicting cloud usage fluctuations.

Cons - This model can lead to paying for resources that you may not always use, impacting budget efficiency. 
Any scale-up requirements would add unprecedented costs.

Suitable for - The subscription-based cloud pricing model is perfect for businesses with consistent resource requirements. It offers budget predictability and eliminates the worry of fluctuating costs associated with usage-based models.

3. Reserved Instance Cloud Pricing Model 

This cloud pricing model works like the car lease concept. The Reserved Instances model lets you reserve cloud resources for a predetermined period (1-3 years) at a discounted upfront cost. This model offers significant cloud cost savings for businesses with predictable workloads, guaranteeing capacity and offering substantial cost savings.  Different RI options cater to specific needs, like scheduled instances for fixed usage hours.

Pros - Reserved Instances offer significant cost reductions for businesses with stable cloud usage patterns.

Cons - Quickly adjusting resource allocation can be challenging with Reserved Instances. Unused resources during periods of lower usage would impact cost efficiency.
The commitment is for a specific instance.

Suitable for - The RI based cloud pricing model is most appropriate for businesses with predictable usage.

4. Spot Pricing Model for Cloud

Spot Instances offer fluctuating prices based on supply and demand, just like the stock market. These are available at a specific time, but the provider may pull back these resources at a notice of just a few minutes resulting in interruptions.

Pros -  Spot instances are available at highly discounted prices.

Cons - Spot Instances are unsuitable for applications requiring guaranteed uptime, like databases or e-commerce platforms.

Suitable for - Spot Instances are ideal for flexible workloads being used for non-essential tasks that can tolerate interruptions. They can be used for non-critical workloads like batch processing or simulations.

5. AWS Savings Plan

This cloud pricing model offers discounted rates compared to on-demand pricing in exchange for a one or three-year commitment, just like Reserved Instances. However, savings plans are more flexible as your commitment is based on total hourly spending across various AWS services, not specific instances. When you enroll in Savings Plans, you lock in prices for usage throughout the plan term. You can choose to pay for your commitment upfront with All upfront, Partial upfront, or No upfront payment options.

AWS Savings Plans are of three types, offering flexibility to match your needs:

  • Compute Savings Plans: These plans offer the broadest coverage, applying discounted rates to your entire bill across various compute services like EC2, Lambda, and Fargate.
  • EC2 Savings Plans: Tailored specifically for Amazon EC2 instances, these plans provide targeted discounts if your workloads primarily rely on EC2.
  • SageMaker Savings Plans: Focus is solely on reducing costs for your SageMaker usage, ideal in case of heavy utilization of SageMaker for machine learning tasks.

Pros - The commitment is for a specific dollar amount resulting in cost advantage and more flexibility.

Cons - Savings Plans cannot be sold in the AWS Marketplace. Once the plan is purchased, the buyer is locked into that commitment. The terms of the commitment cannot be altered once the purchase has been made.
Suitable for -  The savings plans are suitable for organizations with flexible resource requirements and predictable usage that can be committed in advance.
