AWS App Runner
What is it
A fully managed service that makes it easy to create, deploy, and run web applications and API services in containers, without the need to manage the underlying infrastructure.
What it's for
Simplifying the process of putting applications into production, automatically handling building, deployment, scaling, and load balancing.
Use cases
- Quick deployment of web applications and APIs
- Running microservices and application backends
- Development and testing of containerized applications
- Hosting websites and front-end applications
- Scenarios where simplicity and deployment speed are priorities
Key points
- Fully managed: AWS handles infrastructure, load balancing, auto-scaling, and SSL certificate management
- Deployment from source code or container image: Supports direct deployment from code repositories (e.g., GitHub) or container images (e.g., ECR)
- Automatic scaling: Automatically scales up and down based on traffic
- Cost-effective: Pay only for the resources you use
- Integration: Integrates with AWS VPC, AWS IAM, and other AWS services
Comparison with Amazon ECS/EKS/Fargate
- AWS App Runner: The simplest and fastest option for deploying containerized applications, ideal for developers who want to focus on code rather than infrastructure. Offers less granular control over the container environment.
- Amazon ECS (Elastic Container Service): A container orchestration service that offers more control and flexibility over container deployment and management. Can run on EC2 instances (EC2 Launch Type) or in a serverless model with AWS Fargate.
- Amazon EKS (Elastic Kubernetes Service): A managed Kubernetes service that offers the highest level of control and flexibility for container orchestration, ideal for teams already using Kubernetes or needing its portability and ecosystem.
- AWS Fargate: A serverless compute engine for Amazon ECS and EKS that allows running containers without provisioning or managing servers. App Runner uses Fargate under the hood but abstracts away even more complexity.
