# 4 Types of Cloud Pricing Models Explained: AWS, GCP & Azure The global market for cloud computing is expected to reach $912.77 billion in 2025. Businesses are drawn to the cloud environment by its ease of use and technical dominance. There are numerous cloud service providers on the market right now. Microsoft Azure, Google Cloud, and Amazon Web Services (AWS) are the top three competitors in the cloud computing domain.  When using the cloud environment, you need to understand how the resources are priced and what are the discounts available to get maximum discounts for your cloud infrastructure. Poor understanding of the cloud pricing models leads to unwanted cloud expenses. In this article, we will discuss what are the different pricing models offered by the major cloud service providers. ## The Cloud Pricing Models The cloud pricing models determine how your business pay for the cloud resources and services. These pricing models are designed with flexibility to cater to the various need of your organization at the lowest possible cost. The cloud infrastructure is priced basically on the pay-as-you-go principle. This means, you are charged only for the resources you consume, such as storage, compute power, or bandwidth. The cloud pricing model does not involve any upfront payment or long term commitments. Therefore, it is ideal for businesses with dynamic or unpredictable workloads. The pricing model of the top three cloud providers, AWS, GCP, and Azure, are almost the same. If you’re new to the cloud, it’s important to note that all three providers offer free tiers or trial periods. This is an excellent way to test their services without spending money. ## On-Demand Pricing On-demand pricing is one of the most popular cloud pricing model availbale in AWS, GCP and Azure. On-demand pricing is as simple as it sounds. You pay for what your use and nothing more. This pricing model is a flexible option for businesses with varying workloads. - With AWS On-Demand Pricing, you are charged by the second or hour for compute resources, depending on the service. For example, you can run an [EC2 instance](/ec2-instance-types/) and pay only for the time it’s active. Once you stop using the instance, billing stops. This is ideal for short-term projects, development environments, or spiky workloads. - GCP On-Demand Pricing also works similarly. You are billed per second for virtual machines, storage, and other services. One advantage with GCP is their [sustained-use discounts](/gcp-sustained-use-discounts-cost-optimization/). If you use a resource continuously over a billing period, you get automatic discounts without any upfront commitments. - Azure On-Demand Pricing also follows a pay-as-you-go model. You are billed per second or minute for services like virtual machines, storage, and databases. Azure also allow you to mix on-demand pricing with reserved or spot pricing, giving you more control over your expenses. ## Reserved Instances Resserved Instances are a great way to save money is you know how much capacity you need. AWS, GCP and Microsoft Azure all offer reserved instance options. This pricing model lets you commit to a specific capacity at a discounted price for a period of 1 to 3 years. Reserved instances offers a significant discount compared to on-demand pricing. - [AWS offers Reserved Instances](/aws-reserved-instances-overview/) for services like EC2. When you choose a Reserved Instance, you lock in a fixed capacity for a set period. Discounts can go up to 72% compared to on-demand pricing. AWS gives you flexibility too. You can choose from different payment options: No upfront payment – You pay monthly with no initial cost. Partial upfront payment – You pay part of the cost upfront and the rest monthly. All upfront payment – You pay the full cost at once for maximum savings. - No upfront payment – You pay monthly with no initial cost. - Partial upfront payment – You pay part of the cost upfront and the rest monthly. - All upfront payment – You pay the full cost at once for maximum savings.  Source: Economize - Google Cloud calls its reserved option as [Committed Use Discounts](/committed-use-discounts-cud-gcp-cost/). Like AWS, you commit to using resources for one or three years. Discounts can be as high as 57%. It applies discounts to several services like Compute Engine and BigQuery. - Microsoft [Azure offers Reservations](/azure-reserved-instances/) for its Virtual Machine Instances. If your needs change, Azure lets you to exchange or cancel your reservations. You can save up to 72% with Azure reservations compared to pay-as-you-go cloud pricing model. Azure also gives you payment options like: Upfront payment – Pay for the full term at once. Monthly payment – Spread the cost over time. - Upfront payment – Pay for the full term at once. - Monthly payment – Spread the cost over time. ## Spot Instances Spot instance are nothing but unused cloud capacity offered at a discounted price. These are useful for workloads that are flexible and can handle interruptions. This cloud pricing models offers the maximum discount compared to other pricing options. To make the most of spot instances, you can combine them with other pricing models. But it is also important to note that these are not ideal for workloads that relies on constant uptime or needs to save data mid-task. - [AWS Spot Instances](/aws-ec2-spot-instances-cost-reduction/) can save you up to 90% cloud cost compared to the on-demand prices. These are ideal for workloads that are flexible or non-critical. For example, they’re perfect for data processing, machine learning training, or batch jobs. But AWS can reclaim the instance with just a two-minute warning if it’s needed elsewhere. This makes them unsuitable for tasks that need constant uptime. AWS also gives you tools like Spot Fleet. This lets you manage multiple spot instances and maintain availability by automatically replacing reclaimed ones. - In Google Cloud, these are called Preemptible VMs. They work much the same way as AWS Spot Instances. You can save up to 80% compared to regular virtual machines. Preemptible VMs are great for tasks like rendering videos, running simulations, or any workload that doesn’t need to run continuously. GCP gives you a 24-hour limit for each Preemptible VM. After that, the instance is stopped. Like AWS, Google can reclaim the resource at any time. - [Microsoft Azure offers Spot Virtual Machines](/azure-spot-vm-pricing/) that offers deep discounts, sometimes as much as 90% off standard rates. They’re ideal for workloads that are interruptible, like testing environments, containerized applications, or batch processing. Azure also gives you tools to help manage spot VMs. For instance, you can set a maximum price you’re willing to pay. If the spot instance price goes above your set limit, the instance will automatically stop. ## Savings Plan Savings Plan is a cloud pricing model that let you lower your cloud expenses by committing to consistent usage over a set period of time. The commitment period is usually one or three years. The longer the term, the bigger the discount. This pricing option works best if you have a consistent workload. - [AWS Savings Plan](/aws-savings-plan/) commit to a set amount of compute usage, measured in dollars per hour, for a one- or three-year term. You can get a discount of upto 72% with this cloud pricing model. There are two types of savings plan in AWS: Compute Savings Plans and EC2 Instance Savings Plans. Compute Savings Plans apply to EC2 instances across [AWS regions](/how-aws-region-affects-pricing/), instance types, or operating systems. EC2 Instance Savings Plans, however, offer higher discounts but are specific to a region and instance family. - Compute Savings Plans apply to EC2 instances across [AWS regions](/how-aws-region-affects-pricing/), instance types, or operating systems. - EC2 Instance Savings Plans, however, offer higher discounts but are specific to a region and instance family. - As discussed earlier, Google Cloud offers [Committed Use Discounts (CUDs)](/gcp-cud-vs-sud/) for long term commitments. These work by committing to use specific resources like vCPUs, memory, or GPUs for a one- or three-year term. Unlike AWS, these discounts only apply to the exact services you commit to, with no flexibility to switch. CUDs offer up to 57% discounts. GCP also provides Sustained Use Discounts, which automatically apply when you use resources consistently. These don’t require upfront commitments, making them great for less predictable workloads. - [Azure Savings Plans](/azure-savings-plans/) for Compute are also similar. You commit to consistent usage over one or three years and receive discounts on Virtual Machines and other compute services. Azure allows you to adjust your usage across regions and VM types, offering a maximum discount of up to 65%. Here’s a comparative table summarizing the cloud pricing models of AWS, GCP, and Azure: | **Pricing Model** | **AWS** | **Google Cloud (GCP)** | **Microsoft Azure** | | --- | --- | --- | --- | | **On-Demand** | Pay for resources per second or hour.

These are the other factors that influence your cloud bill: ### Data Transfer All three providers charge for data transfer. Traffic within the same region is often free or low-cost, but sending data across regions or the internet is costlier. To save money, minimize unnecessary data transfers and use services like Content Delivery Networks to cache data closer to your users. ### Storage Cost In AWS, GCP, and Azure, storage cost varies by type. Standard storage is affordable for frequently accessed data, while options like cold storage or archival tiers are cheaper for infrequent use. However, accessing data from these lower-cost tiers often comes with retrieval fees. Use the right storage tier for your data’s needs to avoid unnecessary charges. ### Networking and Load Balancers Load balancers distribute traffic, which helps with performance, but they come with hourly and data transfer fees. Similarly, VPNs or private network connections (like AWS Direct Connect or Azure ExpressRoute) offer secure links to your cloud resources but can cost more than expected if your traffic is high. Use these services wisely and monitor usage to prevent surprises. ### Security and Compliance Features like encryption, firewalls, and compliance certifications are also chargeable. Tools like Azure Security Center or AWS GuardDuty can help protect your environment which are charge based on your data volume or resources monitored. Always be mindful about balancing your security needs with your budget. ### Monitoring and Management Tools Monitoring tools keep your cloud environment running smoothly. All cloud service providers offers tools to help you track cloud metrics, logs, and application performance. These tools charge based on the volume of data they process and store. But these cloud-native tools may not always provide the efficiency you are paying for. It is always better to use a dedicated cloud management tool to optimize your cloud infrastructure. ## Simplify cloud Cost Optimization with Economize Managing cloud costs manually is not an easy task.
