Answer: Docker multi-container platform
Overall explanation Correct option: Docker multi-container platform Docker is a container platform that allows you to define your software stack and store it in an image that can be downloaded from a remote repository. Use the Multicontainer Docker platform if you need to run multiple containers on each instance. The Multicontainer Docker platform does not include a proxy server. Elastic Beanstalk uses Amazon Elastic Container Service (Amazon ECS) to coordinate container deployments to multi-container Docker environments. Incorrect options: Docker single-container platform - Docker is a container platform that allows you to define your software stack and store it in an image that can be downloaded from a remote repository. Use the Single Container Docker platform if you only need to run a single Docker container on each instance in your environment. The single container platform includes an Nginx proxy server. Custom Platform - Elastic Beanstalk supports custom platforms. A custom platform provides more advanced customization than a custom image in several ways. A custom platform lets you develop an entirely new platform from scratch, customizing the operating system, additional software, and scripts that Elastic Beanstalk runs on platform instances. This flexibility enables you to build a platform for an application that uses a language or other infrastructure software, for which Elastic Beanstalk doesn't provide a managed platform. Compare that to custom images, where you modify an Amazon Machine Image (AMI) for use with an existing Elastic Beanstalk platform, and Elastic Beanstalk still provides the platform scripts and controls the platform's software stack. Besides, with custom platforms, you use an automated, scripted way to create and maintain your customization, whereas with custom images you make the changes manually over a running instance. Third Party Platform - This is a made-up option.
