AWS recently launched a new service called App Runner. This fully managed containerized application service helps build, deploy, and run web applications, microservices, and APIs within minutes from the source code or using Container Image.

AWS manages the underlying infrastructure and resources by adhering to best security practices by providing the automatic integration and delivery pipeline with fully managed operations, high performance, scalability, and security. Currently, AWS App Runner is supported in five regions: US East (N. Virginia), US East (Ohio), US West (Oregon), Europe (Ireland), and Asia Pacific (Tokyo).

AWS App Runner provides per-second billing and will get a public endpoint with a verified TLS certificate with minimal steps. App Runner can use our existing containers or the integrated container build service to deploy applications directly from the code repository.

AWS App Runner also works with AWS Copilot to containerize the application and automate other services like Amazon DynamoDB.

View Logs of the Service:

In the Service dashboard, you will be able to see below logs:

  • Event log: Displays the latest events and the lifecycle of the App Runner Service
  • Deployment logs: Displays the log stream for each of the deployments for the service
  • Application logs: Displays the output of the web application deployed in App Runner

  • Easy to Use
  • Scales with traffic
  • Saves time

Use Cases

  • Frontend and Backend web applications
  • Microservices and APIs
  • Rapid production deployments


AWS App Runner helps developers deploy the application in minimal steps without intervening with the developer in infrastructure and resource selection, providing better security, monitoring, and high application availability.

One can make the best use of App Runner to deploy applications without worrying about configuring servers, security, and scalability issues. We have learned how to deploy a simple web application right from source code. To know about newly launched AWS services in 2021, here is a blog on AWS re:Invent 2021 highlights.
