AWS Fargate Costs and Pricing Model Explained

AWS Fargate offers a serverless container orchestration service where you don’t manage servers or provision instances. Instead, you focus on container images and configurations. Fargate pricing has five independently configurable dimensions:

1. vCPU

This determines the processing power allocated to your container. Prices vary based on region and vCPU family. For example, in the US East (N. Virginia), a single vCPU for the x86_64 architecture costs $0.00434 per hour.

2. Memory 

This specifies the amount of RAM available to your container. Pricing follows a similar structure to vCPU, with costs per GiB per hour. In the same region, 1 GiB of memory is charged at $0.00065 per hour.

3. Operating System

Fargate supports Linux and Windows containers. Windows generally incur higher charges, so factor this in when choosing.

4. CPU Architecture 

You can choose between x86-64 (standard) and ARM64 (newer, potentially cheaper) architectures. Consider your application’s compatibility and cost before selecting.

5. Storage Resources

This encompasses two components:

• Ephemeral Storage: This temporary storage resides on the container instance and disappears when the task ends. It’s accessible up to a point (e.g., 200 GiB in US East (N. Virginia), then incurs per-GiB charges exceeding that limit.
• Fargate Storage: This persistent storage option lets you attach EBS volumes or use the new AWS Fargate Storage service.

For cost calculation, multiply the individual cost rates of each dimension you configure to get your total hourly Fargate cost. Remember that temporary storage charges only apply if you exceed the free tier.

AWS Fargate is a serverless compute engine for containers, allowing users to run containerized applications without the need to manage the underlying infrastructure. Several configurable dimensions determine Fargate pricing, each impacting the overall cost.

Let’s break down the cost calculations for three different app sizes running on AWS Fargate.

Small Apps

• Small app has fewer than 20 concurrent users, each consuming less than 50MB over 5 minutes.
• Capacity planning considers peak memory requirements and monitoring resources.
• Fargate is configured with two tasks, each with 1GB memory and 0.25 vCPU.
• The monthly cost is calculated for two tasks running for 0.09 hours a day.
• The total monthly cost is approximately $0.16.

Medium-sized Apps

• Medium-sized app has 50 concurrent users, each consuming between 50MB and 80MB of memory over 5 minutes.
• Capacity planning considers peak memory requirements and monitoring resources.
• Fargate is configured with five tasks, each with 6GB memory and two vCPUs.
• The monthly cost is calculated for five tasks running for 0.09 hours a day.
• The total monthly cost is approximately $1.50, including temporary storage charges.

Large-sized Apps:

• Large-sized app has more than 100 concurrent users, with each user consuming more than 100MB over 5 minutes.
• Capacity planning considers peak memory requirements and monitoring resources.
• Fargate is configured with five tasks, each with 16GB memory and four vCPUs.
• The monthly cost is calculated for five tasks running for 0.09 hours a day.
• The total monthly cost is approximately $3.24, including ephemeral storage charges.

In each scenario, capacity planning involves estimating memory and CPU requirements, with buffer capacity for peaks and resources for monitoring. The choice of the number of tasks, memory, and vCPUs is based on these estimations.

The cost is then calculated based on the number of tasks, task duration, vCPU charges, memory charges, and ephemeral storage charges, if applicable.

It is a challenge for DevOps to manage the costs of their operations. Therefore, it’s essential to carefully plan and configure Fargate resources to match the specific needs of your application.

Oversizing or undersizing can significantly impact your monthly costs, so it’s crucial to strike the right balance between performance and cost efficiency.

How Does AWS Fargate Pricing Work?

It is designed to provide a flexible and granular cost structure for running containers without managing the underlying infrastructure. Fargate pricing is primarily based on four key dimensions:

vCPUs per Hour

The Fargate pricing model works by charging per vCPU per hour. Launching a Fargate task lets one specify the amount of CPU capacity. It is what you would need in terms of vCPUs. The vCPUs cost increases by allocate allocating more vCPUs. 

• vCPU Charges (4 vCPUs) = 152.08 tasks x 4 vCPUs x 0.09 hours x 0.04048 USD per hour = 2.22 USD for vCPU hours.

With vCPUs, Fargate provides virtual central processing units that allow you to efficiently manage and allocate CPU capacity. With this realization of how vCPUs are charged and their impact on cost, you can optimize your resource allocation. 

The respective calculation demonstrates how the price for vCPU hours is calculated based on the number of vCPUs allocated. This level of detail helps you assess the financial implications of your resource allocation strategy, enabling you to optimize costs and efficiently use the Fargate service.

Memory per Hour

Fargate also charges per GB of memory per hour. Like vCPUs, you specify the amount of memory required for your tasks.

The cost increases with more memory allocation. In this case, the memory allocation is 16 GB. With this allocation, the calculation for memory charges would be as follows: 

• 152.08 tasks x 16 GB x 0.09 hours x 0.004445 USD per GB per hour, resulting in a total of 0.97 USD for GB hours.

Task Duration

Fargate pricing considers the duration of your tasks, measured in hours and minutes. Your billed pricing is proportional to the actual time your tasks are active. Thus, the duration of your tasks can significantly impact your monthly costs. 

For example, if a task runs for 5 minutes, it equals 0.09 hours. Therefore, optimizing task duration can help you manage your costs more effectively.

Networking

Data transfer costs are associated with Fargate tasks. Ingress, which refers to data going into Fargate, is often free, while egress, which relates to data leaving Fargate, incurs a cost.

Efficiently managing data transfer through optimized network configurations and traffic routing can help control costs and ensure cost-effective utilization of resources. 

By implementing strategies such as caching, content delivery networks, or data compression, organizations can further optimize data transfer and minimize expenses while maximizing the performance and efficiency of their Fargate tasks.

Number of Tasks

To calculate the number of tasks per day, we divide the total number of hours in a month (730) by the number of hours in a day (24). It explains to us an average of 152.08 tasks per month. 

By considering the daily workload, this calculation provides a comprehensive measure of productivity over a monthly period. It considers the variations in workload and ensures a more accurate assessment of task management efficiency.

Ephemeral Storage Charges

The total amount of temporary storage per task is calculated by subtracting the 20 GB of storage that incurs no additional charge from the initial 50 GB. What does it mean? This suggests that you only pay for the billable amount of temporary storage, which is the resulting 30.00 GB for every task. 

This ensures that you are only charged for the storage you use. This is precisely what makes it a cost-effective solution for your storage needs. And 152.08 tasks x 30.00 GB x 0.09 hours x 0.000111 USD per GB per hour = 0.05 USD for ephemeral storage GB hours.

Additionally, you can incur charges for ephemeral storage if your Fargate tasks use temporary storage. AWS provides a small amount of brief storage for free but adds to the overall cost if your tasks require more.
