AWS App Runner adds 7 new compute configurations to the App Runner service settings. App Runner makes it easier for developers to quickly deploy containerized web applications and APIs to the cloud, at scale, and without having to manage infrastructure. With App Runner, you do not have to manage any load balancers and auto-scaling groups. When you create an App Runner service, you select a compute configuration, a combination of vCPU and compute memory, for your web application or API, and define maximum concurrency, the maximum number of concurrent requests one application instance can process. App Runner automatically scales your application instances based on concurrent requests that your App Runner service receives.
