Understanding AWS App Runner

  • Umer Jamil

Do you know about the AWS App Runner service?

A relatively new service in the AWS serverless deployment family, it’s a game changer for running containerized services without a server.

The official AWS page introduces App Runner as

AWS App Runner is a fully managed container application that lets you build, deploy, and run containerized web applications and API services without prior infrastructure or container experience.

To further understand the App Runner’s services, key offerings, workflow, configuration, and pricing model we will dig a little deeper and look into the pros and cons of using this service.

Why App Runner?

Managing infrastructure, which includes but is not limited to tasks such as configuring SSL certificates, encrypting traffic, configuring VPC security groups, setting up message queues, and implementing autoscaling can make it appear overwhelming. A SaaS service like App Runner is a possible solution to simplify managing infrastructure.

Features of App Runner

A few features of the App Runner are

  • Efficient: auto build and deployment from code repositories and ECR.
  • Scalability & load balancing: automatically scale up and scale down the service based on the ingress traffic.
  • Security: ease of setting up and configuring SSL certificates.
  • Monitoring and logging: well integrated with AWS cloud watch.

The workflow of the AWS App Runner is simple and straightforward, as shown in the picture

The above workflow can be summarized into three significant steps

  1. Add a source (git repo, ECR)
  2. Configure build and service settings (hardware configuration such as vCPUs, RAM, ports, autoscaling, etc)
  3. Deployment with a click of a button

A few cons of the App Runner service are

  • App Runner supports the following hardware configuration. So, if your service needs more RAM/vCPU resources, consider looking at ECS or EC2.
CPUMemory Values
  • It does not support GPUs.
  • The service is only available in the following regions: Europe (Ireland), Asia Pacific (Tokyo), US East (N. Virginia), US East (Ohio), and US West (Oregon). However, this may change in the future.
Pricing Model

The pricing model is based on the compute and memory resources that our active/provisioned container instance is using.

The features included in the pricing model are

  1. Provisioned container instances
  2. Active container instances
  3. Automatic deployments
  4. Build fee
  5. Data transfer rates
