In this Article we discuss that, Cost of Hosting an App in Fargate: AWS Fargate Pricing In 2023? The cost of hosting an app in Fargate with AWS can vary depending on several factors such as the size of the application, the number of containers required, the amount of storage needed, and the level of traffic the application receives.
Fargate pricing is based on the amount of vCPU and memory resources used by your containers. You can choose to pay for Fargate resources on-demand or opt for a reserved pricing model for additional cost savings.
In addition to Fargate resources, other AWS services used in conjunction with Fargate may also impact the overall cost. For example, if you use Amazon RDS for your database or Amazon S3 for storage, you will need to pay for those services separately.
To get a better idea of the cost of hosting your specific app in Fargate with AWS, you can use the AWS Simple Monthly Calculator. This tool allows you to input your app’s requirements and estimate the monthly cost of hosting in Fargate along with any other AWS services you plan to use.
What is Fargate?
Fargate is a serverless computing engine that frees you from having to handle the underlying infrastructure in order to deploy and maintain apps, APIs, and microservices. By only charging for the resources actually used, it also reduces expenditures.
Just bundle your application into containers, specify memory/processor configuration and IAM policies, then launch the application to use Fargate. Scaling is made simple and easy via Fargate. It is compatible with Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS) (ECS).
Why Bother about Fargate Pricing?
Since that AWS Fargate is a fully managed serverless product, why worry about its price? You ought should!
as opposed to the size of the container or pod, AWS manages the hardware of the container platform.
as opposed to their sizes, AWS automatically scales the number of containers/pods.
Use the appropriate-sized containers for the appropriate tasks in order to balance cost and performance.
The appropriate size of the containers/pods is determined by the application’s resource footprint, the web server, the computing platform, and the libraries.
AWS Fargate Pricing: Real Costs and Pricing Structure
Fargate does not have any up-front expenses from AWS. Only the resources that were used must be paid for.
Fargate cost is primarily determined by the desired vCPU and memory capabilities. However, its pricing is impacted by additional factors.
The five independently customizable Fargate pricing dimensions are as follows:
- vCPU
- Memory
- Running System
- The Design of the CPU
- Device Resources
For instance, in the US East Ohio region, AWS costs $0.004445 per 1 GB per hour and $0.04048 per hour for one vCPU for Linux/x86 architecture. The costs increase to $0.03238 per vCPU and $.00356 per GB per hour when ARM CPU architecture is used.
The cost is $0.09148 per vCPu and $0.01005 per GB per hour for Windows / x86.
The price of vCPU and memory varies by area, CPU architecture, and operating system, as you can see from the table above. It’s vital to remember that only Amazon ECS and a few specific countries support Windows OS and ARM Processor architecture options. So, it’s crucial to take into account each of these factors when determining the Fargate cost.

AWS Fargate Pricing Examples
1) Small Apps
Assume a simple app with fewer than 20 concurrent users, each of whom uses less than 50 MB over a five-minute period.
Capacity Planning is the initial stage.
During the development phase, determine the delta memory consumption for each user and multiply it by the number of concurrent users.
For instance, 20 people using 50 MB each equals 1000 MB.
Set aside 500 MB as buffer RAM for peak demands.
A further 500 GB should be set aside for processes used for container monitoring, such as Amazon CloudWatch, Grafana, or Prometheus.
About 2 GB of RAM are available overall.
Get the vCPU value that corresponds to 2 GB: 0.5 vCPU
The sum drops to 2 GB and 0.5 vCPU for two activities that each use 1 GB of memory and 0.25 vCPU.
When estimating the average monthly cost:
Number of Tasks: 2 every day, which equates to 60.83 per month (730 hours in a month divided by 24 hours).
Task Duration: 5 minutes = 0.09 hours of vCPU charges (0.5 vCPu) = 60.83 tasks times 0.50 vCPU times 0.09 hours times 0.04048 US dollars per hour = 0.11 US dollars for vCPU hours.
Memory Costs (2 GB): 60.83 tasks times 2.00 GB times 0.09 hours times 0.004445 USD for every GB for every hour equals 0.05 USD for GB hours.
Costs for Ephemeral Storage: 20 GB – 20 GB (no additional fee) = 0.00 GB chargeable ephemeral storage per task
2) Medium-sized Apps
50 users are using a medium-sized app simultaneously, and each user uses between 50MB and 80MB of memory over the course of 5 minutes.
When estimating the average monthly cost:
There are 5 tasks every day, or 730 hours per month divided by 24 hours per day, or 152.08 tasks per month.
Task 5 minutes is equal to 0.09 hours.
vCPU Costs (2 vCPu) = 1.11 USD for vCPU hours or 152.08 tasks x 2 vCPU x 0.09 hours x 0.04048 USD per hour.
Memory Costs (6 GB): 152.08 tasks times 6 GB times 0.09 hours times 0.004445 US dollars per GB per hour equals 0.37 US dollars for GB hours.
Costs for Ephemeral Storage: 30 GB – 20 GB (no additional fee) equals 10.00 GB chargeable ephemeral storage per task.
0.02 USD for ephemeral storage GB hours is equal to 152.08 tasks multiplied by 10.00 GB by 0.09 hours and 0.000111 USD per GB per hour.
The monthly cost for Fargate is 1.11 USD for virtual CPU hours, 0.37 USD for gigabyte hours, and 0.021 USD for temporary storage. 1.50 USD per Gigabyte hour
3) Large-sized Apps
A large-sized software has more than 100 concurrent users, and each one uses more than 100 MB of memory over the course of five minutes.
When estimating the average monthly cost:
There are 5 tasks every day, or 730 hours per month divided by 24 hours per day, or 152.08 tasks per month.
Task 5 minutes is equal to 0.09 hours.
vCPU Costs (4 vCPu) = 2.22 USD for vCPU hours or 152.08 tasks x 4 vCPU x 0.09 hours x 0.04048 USD per hour.
Memory Costs (16 GB): 152.08 tasks times 16 GB times 0.09 hours times 0.004445 USD for each GB per hour equals 0.97 USD for each GB of time.
Costs for Ephemeral Storage: 50 GB – 20 GB (at no additional cost) = 30.00 GB chargeable ephemeral storage per task
152.08 tasks multiplied by 30.00 GB, which took 0.09 hours to complete, resulted in 0.05 USD for every GB hour of temporary storage.
The monthly cost for Fargate is 2.22 USD for virtual CPU hours, 0.97 USD for gigabyte hours, and 0.05 USD for temporary storage. 3.24 USD per Gigabyte hour
How To Reduce Costs in AWS Fargate?
Here are the top four AWS Fargate cost-saving strategies:
1) AWS Savings Plan:
No matter the location, operating system, tenancy, size, or instance family, Amazon Savings Plan enables you to receive discounts on computing workloads of up to 72%. It automatically gives you the discount when you use Fargate and EC2 instances. Nevertheless, the plan necessitates a commitment of 1-3 years for a specific quantity of consumption (billed per hour).
Regardless of shifting on-demand prices, once a subscription has been made, the prices are locked in for the duration of the contract. There are several ways to pay, including no upfront payment, partial upfront payment, and full upfront payment.
You can plan an Amazon Savings Plan while proactively managing the plan based on budget alerts and performance monitoring reports by taking a cue from the AWS Cost Explorer in the form of recommendations. The standard on-demand rates are immediately charged to your account once your membership expires.
2) Fargate Spot Instances:
You can get a discount on Fargate price of up to 70% with AWS Fargate Spot, which is a great feature for Amazon ECS tasks that can withstand interruptions. On-demand and Spot instances resemble one another in most regards, but they differ in two ways: the costs per GB and per vCPU can vary by up to 70%, and processes can be interrupted.
All availability zones have the same pricing, however it changes throughout the day. The astounding pricing is due to AWS’s availability of surplus capacity in the cloud.
Please be aware that AWS removes these instances with a 2-minute notice when it wants the capacity back. Because of this, you should run interruption-tolerant processes to take advantage of this reduction without sacrificing availability.
It’s crucial to finish jobs politely. The Fargate spot pricing model works best for tasks like genomic processing, picture rendering, CI/CD, stateless web servers, and containerized workloads, to name a few.
The cost of a Fargate ad is determined by the number of seconds used, with a minimum of one minute. You just pay for the resources that are actually used; there are no up-front costs. When a container image begins to download, billing begins and continues until the operation is finished.
3) Right-sizing Fargate duties:
Right-sizing Fargate tasks are crucial for cost optimisation. Fargate task overprovisioning is a frequent error that raises cloud prices.
Consider the cold starts and performance difficulties while selecting smaller containers in greater quantities while keeping in mind the cheaper costs. Alternatively, choosing large-sized containers in smaller quantities wastes resources. The jobs should ideally occupy at least 85% of the available computing power.
Correctly sizing Fargate assignments
Examine how much memory is being used during development. You may get a sense of how much memory an app is using with CloudWatch Application Insight.
Decide how many users are active at once, and multiply those figures accordingly.
For that task, ascertain the corresponding vCPU numbers.
Conduct load testing to assess how well the setup performs under the allocated load.
Adjust resource distributions.
Create auto-scaling rules that strike a balance between performance and cost. Check the application’s performance at baseline and under load as a best practise to properly configure auto-scaling strategies.
4) Tagging Resources:
Tag your AWS Fargate resources, such as task definitions, clusters, container instances, services, etc. to increase workload visibility while reducing expenses. You can reduce cloud waste by finding orphaned resources that are idle.
By tagging your resources, you can more easily grant rights at the resource level and methodically control the expenses of workloads distributed across diverse teams, environments, and business units.
AWS ECS Costs – Without Fargate
Two launch kinds are available through AWS Elastic Container Service (ECS), EC2 instance and Fargate. Regardless of the percentage of resource utilisation, when you utilise an EC2 launch type, you’ll be paying a fixed price for the RAM and CPU supplied for that instance type.
The Fargate cost, on the other hand, is dependent on the amount of resources used for a single job, allowing you to appropriately size the instance.
With a one-year term and no upfront payment, the compute savings plans rate for m5.xlarge in the US East (Ohio) is 0.141 USD.
Total time invested: 8760.0000 hours are equal to 365 days * 24 hours * 1 year.
Total Investment: 0.141 USD multiplied by 8760 hours is 1235.1600 USD.
No Upfront (0% of 1235.16) is 0.0000 US dollars.
Hourly cost for compute savings plans is calculated as follows: (1235.16 – 0.00)/8760 = 0.1410 USD; Total Commitment – Upfront Cost
The monthly cost for normalised compute savings plans is (0.000000 USD / 12 months) plus (0.141000 USD x 730 hours) = 102.930000 USD.
For the same configuration (Always Active), Fargate charges the following monthly fee:
(16 GB x 0.00445 USD per hour x 24 hours x 30 days) plus (4 vCPU x 0.04048 USD per hour x 24 hours x 30 days) equals $167.78.
It’s vital to keep in mind that Fargate pricing starts to drop as resource idle time rises.

AWS EKS Costs – Standalone with no Fargate Service
Amazon EKS has a fee of $0.10 per hour per EKS cluster you establish, however AWS ECS is free and you only pay for the EC2 instances used. These clusters’ utilisation of computation and storage resources entails additional fees. In comparison to ECS, it means that you will pay an extra $74 per cluster every month.
The ease with which you can manage container clusters overcomes the pricing difference with EKS, a fully-managed Kubernetes service. For instance, you can run many apps on a single EKS cluster.
Fargate vs ECS vs EKS: Pricing Comparison
Fargate charges extra for vCPU and GB resources when compared to ECS or EKS pricing. Unfortunately, AWS measures RAM and CPU separately and does not include the capacity of the idle cluster. So, in terms of expenses, the cluster reservation rate is the deciding factor.
Conclusion
When compared to Fargate, you’ll save 20% to 30% on prices if your ECS cluster is utilised at 100%. You will pay more than Fargate pricing if the percentage is lower than 80%. However take into account the infrastructure management duties like setting up, operating, patching, and securing hosted VMs. Another issue is autoscaling resources at the cluster and container levels.
You save money and reduce infrastructure management’s costs and complexity with the proper-sized Fargate configuration.
