Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It is a fully managed, serverless database that does not require provisioning, patching, or backup. It offers built-in security, backup and restore, and in-memory caching3. Amazon RDS is a relational database service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching, and backups. However, it is not a key-value NoSQL database, and it is not serverless, as it requires you to choose an instance type and size4. Amazon Aurora is a MySQL and PostgreSQL-compatible relational database built for the cloud, that combines the performance and availability of traditional enterprise databases with the simplicity and cost-effectiveness of open source databases. However, it is also not a key-value NoSQL database, and it is not serverless, as it requires you to choose an instance type and size. Amazon MemoryDB for Redis is a Redis-compatible, durable, in-memory database service that delivers ultra-fast performance and multi-AZ reliability for the most demanding applications. However, it is also not a key-value NoSQL database, and it is not serverless, as it requires you to choose a node type and size.

AWS CloudFormation allows developers to create, manage, and deploy AWS resources using templates, ensuring a standardized and repeatable infrastructure setup. It’s ideal for setting up development, test, and production environments consistently. AWS Cloud Map, CloudFront, and CloudTrail do not provide templated infrastructure management capabilities.

AWS App Runner is a fully managed service that makes it easy for developers to quickly deploy containerized web applications and APIs at scale. It can automatically build container images from source code or directly from a container registry, and then deploy the application without requiring deep container knowledge or expertise.

AWS App Runner meets the requirements of:

Automatically creating container images from source code.

Managing the deployment of the containerized application with minimal operational overhead.

Why other options are not suitable:

A. AWS Elastic Beanstalk: While it simplifies deploying and scaling web applications, it does not automatically create container images from source code.

B. Amazon Elastic Container Service (Amazon ECS): ECS is a container orchestration service that requires more manual setup for creating and managing container images and deployments.

D. Amazon EC2: This service provides virtual servers but does not offer managed container image creation or deployment.
