In this article, we’ll give you an overview of some of the most common AWS Fargate interview questions and how you can answer them.

AWS Fargate Interview Questions and Answers

Here are 20 commonly asked AWS Fargate interview questions and answers to prepare you for your interview:

1. What is AWS Fargate?

AWS Fargate is a serverless compute engine for containers that works with both Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS). Fargate makes it easy for you to focus on building your applications, and it removes the need to provision and manage servers. With Fargate, you no longer have to worry about patching, cluster capacity, or managing scaling policies.

2. Can you tell me some of the main features and benefits of using AWS Fargate?

Some of the main features and benefits of using AWS Fargate include the following:

-AWS Fargate is a serverless compute engine for containers that eliminates the need for customers to manage or configure their own servers.

-AWS Fargate makes it easy for customers to run containers without having to worry about provisioning or managing servers.

-AWS Fargate is integrated with other AWS services such as Amazon ECS and Amazon EKS, making it easy to launch containers on AWS.

-AWS Fargate is a cost-effective solution for running containers, as customers only pay for the resources they use.

3. How does scaling work for containers running on AWS Fargate?

Fargate automatically scales containers up or down based on the amount of traffic they are receiving. This means that you don’t have to worry about manually scaling your containers to meet demand.

4. What’s your understanding of a Task Definition in the context of AWS Fargate?

A Task Definition is a blueprint that describes how a container should be launched and what it should do. In the context of AWS Fargate, a Task Definition specifies which Docker images to use, how many containers to create, and the required resources for each container.

5. What are some common use cases for AWS Fargate?

Some common use cases for AWS Fargate include containerized microservices, batch jobs, and machine learning inference.

6. Where do we run our container images when using AWS Fargate?

AWS Fargate is a serverless compute engine for containers that allows us to run our container images without having to provision or manage servers. This means that we can simply submit our container images to AWS Fargate and it will take care of running them for us.

7. Can you name some core components of AWS Fargate?

The core components of AWS Fargate are the container agent, task definition, and ECS service. The container agent is responsible for making sure that the containers are running and healthy. The task definition is a blueprint that describes how a container should be run. The ECS service is responsible for managing the tasks and ensuring that they are running as desired.

8. Do I need to create an ECS cluster before launching my first container with AWS Fargate?

No, you do not need to create an ECS cluster before launching your first container with AWS Fargate. Fargate will automatically create a cluster for you and launch your container within that cluster.

9. Does AWS Fargate provide any built-in security measures? If yes, what are they?

Yes, AWS Fargate provides several built-in security measures to help protect your containers and data. These include features like network isolation, firewalls, and encryption. You can also use IAM roles to further restrict access to your Fargate resources.

10. Is there any limit to the number of tasks that can be launched on AWS Fargate at any given point in time?

There is no limit to the number of tasks that can be launched on AWS Fargate at any given point in time. This means that you can launch as many tasks as you need, without having to worry about any sort of limit.

11. Can I use my existing Docker image registry or do I have to use Amazon EC2 Container Registry (ECR) with AWS Fargate?

You can use any existing Docker image registry with AWS Fargate, including Amazon ECR.

12. What pricing models are available for AWS Fargate?

There are two pricing models available for AWS Fargate:

1. On-demand: You pay for the resources that you use, by the second. This is the most flexible option and you only pay for what you use.

2. Spot: You can bid for spare compute capacity in AWS Fargate. If your bid is higher than the current Spot price, your tasks will run. If the Spot price exceeds your bid price, your tasks will be interrupted (but can be restarted automatically when the Spot price falls back below your bid). Spot is a good option if you are looking to save money on your compute costs.

13. Can I run containers on AWS Fargate without having to re-architect them?

Yes, you can. Fargate can run containers that are built for either Amazon ECS or the open-source Docker container runtime.

14. Can I run Kubernetes Pods natively on AWS Fargate?

No, you cannot. Fargate is a managed container service that runs containers on AWS EC2 instances. Kubernetes is a container orchestration platform that can run on top of Fargate.

15. What are some key differences between AWS ECS and AWS Fargate?

The biggest difference between AWS ECS and AWS Fargate is that Fargate removes the need for you to manage your own cluster instances. With ECS, you need to launch and manage EC2 instances to run your containers. Fargate manages the instances for you, so you can focus on building and running your applications. Additionally, Fargate is more expensive than ECS, but it can save you money in the long run by eliminating the need to manage your own instances.

16. Can I manage multiple clusters from different regions with a single set of tools with AWS Fargate?

Yes, you can manage multiple clusters from different regions with a single set of tools with AWS Fargate. This makes it easy to deploy and manage your applications across multiple regions.

17. What types of applications can be deployed on AWS Fargate?

AWS Fargate can be used to deploy any type of containerized application. This includes both stateless and stateful applications, as well as microservices and monolithic applications.

18. Are there any restrictions on how many CPU cores and memory I can use when creating a task definition for AWS Fargate?

No, there are no restrictions on how many CPU cores or memory you can use when creating a task definition for AWS Fargate. You can use as many or as few as you need, depending on the requirements of your application.

19. When should I choose AWS Fargate over other serverless options like Lambda functions?

AWS Fargate is a good choice when you need more control over your serverless environment, or when you need to run containers that are not compatible with Lambda. Fargate is also a good choice if you want to avoid the hassle of managing serverless infrastructure.

20. Which AWS services can be used along with AWS Fargate?

AWS Fargate can be used along with the following AWS services: Amazon ECS, Amazon EKS, and AWS Lambda.
