AWS Pricing: Models, Tiers, And Services Explained In 2024

Key Takeaways: AWS Cloud Computing Pricing

Through its pay-as-you-go model, AWS pricing works by primarily charging based on what you use.
AWS offers discounted rates when you commit long term and when your usage volume increases.
AWS Spot Instances offers one of the highest discounts, but is ideal only for workloads not affected by interruptions.

Facts & Expert Analysis About AWS:

Regional consideration: In addition to varying by service and service tier, AWS pricing varies by region. Weigh prices from different regions against each other to determine the most beneficial option for you. While choosing a region, remember that proximity plays a part in performance.
Free tier: AWS offers a free tier that extends across its major services, including Amazon S3, Amazon EC2 and AWS Lambda. Therefore, you can do a test run of most services before paying.
Budgeting: You can restrict your AWS expenses with AWS Budgets — it sets a threshold for your spending, beyond which a predefined action is triggered. Depending on your configuration, the predefined action may run automatically or alert you for approval.

Amazon Web Services (AWS) pricing primarily follows a pay-as-you-go model, ensuring you pay only for usage. Though this is generally cost-efficient, there are various aspects to AWS billing. If you don’t understand them, you may miss out on huge savings through pricing models like Reserved Instances or Savings Plans.

You may also incur some unexpected expenses if AWS pricing is a bit unclear to you. For instance, when using Amazon Simple Storage Service (S3), your total expense goes beyond storage, as you may have to pay for data transfer or extra security features.

In this AWS pricing guide, we dive into the pricing models, pricing tiers, cost optimization practices and cost management tools available on AWS. We also look into the prices of popular AWS plans and their pricing components.

How Does AWS Pricing Work?

AWS’ primary pricing model involves paying only for what you use. In other words, you pay for the length of time you keep a virtual machine running, the amount of data you transfer or store, and the number of requests you make. It all depends on the unit of usage defined by AWS, which differs from one service to another.

Besides the standard pricing method, AWS offers discounted pricing based on the regular pay-as-you-go rates. Typically, discounts are available when you make a long-term commitment to an AWS service, but they may also be volume-based. For instance, with larger egress out of Amazon S3 you get lower rates.

What Are the Different AWS Pricing Models?

The different AWS pricing models include pay-as-you-go, Reservations, Savings Plans, Dedicated Hosts and Spot Instances. Let’s look into what these pricing models offer.

Pay-As-You-Go

The pay-as-you-go model is the primary pricing model on AWS; it involves paying for a service based on usage without a long-term commitment. However, because pay-as-you-go comes with no commitment, the costs are relatively higher than with commitment-based models.

For many services, the pay-as-you-go units are time-based, i.e., typically per hour, per second and so on. However, they could also be based on other units, such as GB or number of requests.

Reservations

Unlike pay-as-you-go, the Reserved Instances model is a commitment model that offers huge discounts for on-demand resources. For instance, you can get discounts of up to 72% when using Reserved Instances for EC2.

The Reservations model involves a commitment to using a given capacity of a certain service for one year or three years and is available for EC2, Amazon RDS, DynamoDB, OpenSearch, RedShift and ElastiCache.

There are two types of the main Reservations plan on AWS: Standard Reserved Instances and Convertible Reserved Instances. The Standard type offers higher discounts and lower flexibility, while the Convertible type is more flexible but offers lower discounts.

When getting Reserved Instances for EC2, you can scope the reserved capacity either to an availability zone or to a region. You can also buy up to 20 reserved instances in each availability zone per month. If you want more, you’ll have to fill out the reserved instances limit request form.

Savings Plans

Like Reservations, the Savings Plans model involves a one-year or three-year commitment. However, instead of committing to a certain capacity, the Savings Plans model requires a commitment to an hourly spend.

There are three types of AWS Savings Plans:

Compute Savings Plans
EC2 Instance Savings Plans
Amazon SageMaker Savings Plans

Compute Savings Plans are the most flexible, while EC2 Instance Savings Plans offer the highest discount. Amazon SageMaker Savings Plans are dedicated to Amazon SageMaker and offer up to 64% off. In addition to EC2 and SageMaker, you can use Savings Plans with AWS Lambda and AWS Fargate.

Spot Instances

Though not necessarily a pricing model, spot instances are unused EC2 compute that AWS offers at huge discounts of up to 90%. That said, spot instances can be interrupted if EC2 wants to reclaim the spot compute capacity. The Spot Instances model is best for interruption-tolerant workloads, like stateless web servers, rather than mission-critical applications.

Dedicated Hosts

Dedicated Hosts is an EC2 deployment model that allows you to spin up EC2 instances on physical servers reserved just for your use. This model is generally more expensive than other EC2 offerings, but you can save on licensing costs if you bring eligible licenses.

With Dedicated Hosts, the physical servers remain with AWS. It takes care of the administration for you, and you get to use EC2 instances the same way you would on standard AWS but with your own licenses and configurations, and enhanced performance.

What Are the Different AWS Pricing Tiers?

The different AWS pricing tiers include the free tier and the paid tier. Find out more about these pricing tiers below.

Free Tier

AWS’ free tier allows you to use AWS services within certain limits without paying. It is offered in three ways: always free, trials and 12 months free. As the names imply, “always free” services are always free, “12 months free” services are free for 12 months from the day you first sign up for AWS, and “trials” offer free access to services for short periods from the day of first usage.

Always-free services include AWS Shield Standard, AWS Key Management Service (free up to 20,000 requests per month) and Amazon Cognito (free up to 10,000 monthly active users per eligible account). Services free for the first 12 months include Elastic Load Balancing, Amazon Polly and the Amazon EC2 free tier. AWS offers free trials of DocumentDB, Amazon DevOps Guru and others.

Paid Tier

The paid tier includes all usage outside the free tier’s periods or limits. For instance, if you use a 12 months free service beyond the first 12 months, you will be charged. Similarly, if you use more than 20,000 requests per month on AWS KMS — an always free service — you will be charged.

What Are the Prices of Different AWS Services?

The prices of different AWS services vary with the service tier and region. In the interest of space, we’ll discuss only the prices of services in the first AWS region — us-east-1.

Amazon S3

Amazon S3 has eight tiers: Standard, Standard-IA, Intelligent Tiering, Express One Zone, One Zone-IA, Glacier Instant Retrieval, Glacier Flexible Retrieval and Glacier Deep Archive. Storage prices for these S3 tiers vary from $0.00099 per GB with Glacier Deep Archive to $0.16 per GB with Express One Zone.

Other S3 costs include data transfer to the internet, which costs between $0.05 per GB and $0.09 per GB, and data transfer to other regions for $0.02 per GB. You also pay for dual-layer server-side encryption with keys stored in AWS Key Management Service (DSSE-KMS), access grants, replication, management, insights and AWS Lambda transformations and queries.

Amazon EC2

There are at least 800 types of EC2 instances, with prices varying from $0.0042 per hour to $407.68 per hour. Generally, the most expensive instances are in the memory-optimized class of EC2 instances, while the general purpose instances are often the cheapest.

Besides paying for EC2 compute, you also pay for egress at the same rates as S3. Furthermore, you may pay for Elastic IP, Elastic Load Balancing, Elastic Block Store and other add-on services when using EC2.

AWS CloudFormation

When using CloudFormation, the Alexa::* and AWS::* namespaces incur no charges — you pay only for the infrastructure provisioned using CloudFormation. However, for other namespaces, you pay $0.0009 per handler operation and $0.00008 per second of handler operation. You get 1,000 handler operations per month per account for free before you start getting charged.

AWS Elastic Beanstalk

With AWS Elastic Beanstalk, you pay only for the underlying infrastructure. In other words, if your Elastic Beanstalk deployment includes EC2 instances, S3 buckets and RDS instances, you’ll pay only for those services at their regular rates.

What Are the Most Expensive AWS Services?

The most expensive AWS services include Amazon EC2 Dedicated Hosts, Amazon Elastic Kubernetes Service (EKS) and Amazon Neptune. AWS has more than 200 services, whose prices vary across tiers and regions. The prices of these services also vary with usage, so your total expenses may fluctuate based on these factors.

What Are the Cheapest AWS Services?

The cheapest AWS services include Amazon S3 Glacier Deep Archive, Amazon EC2 general purpose instances and Amazon Elastic Block Store (EBS). These services have some of the lowest unit rates on AWS. However, factors such as usage and region ultimately determine the charges you’ll incur when you use them.

What Are the Fundamental Drivers of Cost With AWS Cloud?

Fundamental cost drivers with AWS Cloud include usage, service, service tier, region and pricing model. Logically, since AWS primarily uses pay-as-you-go, the higher your usage is, the higher your AWS costs are and vice versa.

Different services on AWS have different unit rates and pricing components, which affect how much they cost. Similarly, the services have different tiers, with some tiers being more expensive than others.

The prices of services in some regions are different from the prices of the same services in other regions. Your charges may vary depending on the region in which you deploy your services. The pricing model can also make a huge difference — for example, using a commitment-based model instead of pay-as-you-go can make it much cheaper.

How to Optimize AWS Cost

You can optimize AWS costs by matching demand with capacity, removing idle resources and using discounted pricing models. Below, we explore how these measures can help make your AWS resources more cost-efficient.

Matching demand with capacity: To avoid the underperformance that may come with underprovisioning resources, you may inadvertently provision more resources than necessary and spend more than necessary. Rightsizing your deployments and using AWS Trusted Advisor, Auto Scaling and Amazon S3 Analytics can help avoid this.
Remove idle resources: With larger deployments, you stand the chance of provisioning resources you never use or underuse but pay for. To correct this and optimize costs, identify unused and underused resources with tools like AWS Cost and Usage Reports and AWS Trusted Advisor.
Discounted pricing models: When suitable, use discounted pricing models for cheaper running costs. For instance, if you have stateless applications that can tolerate interruptions, use Spot Instances, and if you have long-running workloads, use Reserved Instances or Savings Plans.

What Are the AWS Cost Management Tools?

The AWS Cost Management tools include AWS Budgets, AWS Cost Explorer, AWS Cost and Usage Reports and AWS Trusted Advisor. AWS Cost Explorer provides a visual overview of usage and costs in your AWS account, streamlining cost management, while AWS Budgets allows you to control costs by setting a spending threshold.

AWS Cost and Usage Reports offers detailed data about cost and usage, including information about hourly, daily and monthly costs and resource-specific data. Unlike the others, AWS Trusted Advisor’s role is mostly advisory, as it recommends improvements that can optimize costs.

How Expensive Is AWS?

AWS typically costs about the same as its closest competitors — Azure and Google Cloud — with some pricing disparities. Ultimately, the services you use and how much you use determine what AWS will cost. You may spend less than $10 per month or thousands of dollars per month. The only way to determine your precise costs with certainty is with the AWS pricing calculator.

Is AWS More Expensive Than GCP?

GCP is more expensive than AWS for running memory-optimized instances, but AWS can get more expensive for compute-optimized instances. That said, a blanket comparison of the relative costs of both cloud providers can offer a skewed overview. A better analysis would involve direct comparison for a specific use case.

Is AWS More Expensive Than Microsoft Azure?

AWS and Microsoft Azure have similar prices for general purpose instances, but Azure can cost more for memory-optimized instances. Compare both providers with a specific use case for a precise cost analysis. Thankfully, each one has a pricing calculator, making it easier to estimate practical costs.

Final Thoughts

The primary pricing model on AWS is pay-as-you-go, which charges based on your usage volume. However, discounted pricing models exist for long-term commitments, large usage volumes, and when using unused computes are offered on discount. What’s more, AWS pricing varies across regions, services, tiers, add-ons and so on; when estimating costs, consider these factors.
