Choosing between AWS Fargate and AWS AppRunner depends on your specific application and your development and operational requirements. Here are some factors to consider when deciding where to run your app:

Container Control:

  • Use AWS Fargate if you require fine-grained control over your containers, including custom container orchestration, networking, and more.
  • Use AWS AppRunner if you prefer a more abstracted, managed environment where AWS handles much of the container and infrastructure management for you.


  • If your application has complex networking, scaling, and orchestration requirements, AWS Fargate may be a better fit due to its flexibility.
  • For simpler web applications with fewer customization needs, AWS AppRunner's streamlined approach may be more efficient.

DevOps Expertise:

  • AWS Fargate requires more familiarity with container orchestration tools and AWS services, making it better suited for teams with DevOps expertise.
  • AWS AppRunner is designed to be more developer-friendly and may be a better choice if you have limited DevOps resources.


  • If you need fine-grained control over auto-scaling and have specific requirements for when and how your application scales, AWS Fargate offers more control in this regard.
  • AWS AppRunner simplifies scaling by providing built-in mechanisms, which may be sufficient for many web applications.

Resource Management:

  • If you need to specify exact CPU and memory resource allocation for your containers, AWS Fargate allows for more granular control.
  • AWS AppRunner abstracts resource management to provide a more simplified experience.

Continuous Deployment:

  • Consider your continuous deployment and integration needs. Both AWS Fargate and AppRunner support CI/CD pipelines, but your choice might depend on your existing tooling and processes.

Cost Considerations:

  • Evaluate the cost implications of each service based on your application's resource usage. Fargate charges based on vCPU and memory, while AppRunner has its own pricing model.

Service Ecosystem:

  • Consider how your application integrates with other AWS services. Both services can be integrated, but you might find certain services and features align better with one or the other.

In summary, AWS Fargate provides more control and flexibility for containerized applications and is suitable for complex or highly customized use cases. AWS AppRunner, on the other hand, is designed for simplicity and ease of use, making it a good choice for more straightforward web applications and when you want to reduce the operational overhead. The choice ultimately depends on your specific application's needs and the level of control and customization you require.
