Which solution will meet these requirements?
Use Amazon S3 for web hosting with Amazon API Gateway for database API services. Use Amazon Simple Queue Service (Amazon SQS) for order queuing. Use Amazon Elastic Container Service (Amazon ECS) for business logic with Amazon SQS long polling for retaining failed orders.
Use AWS Elastic Beanstalk for web hosting with Amazon API Gateway for database API services. Use Amazon MQ for order queuing. Use AWS Step Functions for business logic with Amazon S3 Glacier Deep Archive for retaining failed orders.
Use Amazon S3 for web hosting with AWS AppSync for database API services. Use Amazon Simple Queue Service (Amazon SQS) for order queuing. Use AWS Lambda for business logic with an Amazon SQS dead-letter queue for retaining failed orders.
Use Amazon Lightsail for web hosting with AWS AppSync for database API services. Use Amazon Simple Email Service (Amazon SES) for order queuing. Use Amazon Elastic Kubernetes Service (Amazon EKS) for business logic with Amazon Elasticsearch Service (Amazon ES) for retaining failed orders.
Explanations:
Using Amazon SQS for order queuing and ECS for business logic is good for scalability, but SQS long polling for retaining failed orders is inefficient. Amazon SQS is not optimized for retaining failed orders for long periods.
AWS Elastic Beanstalk is suitable for web hosting, but Amazon MQ for order queuing adds complexity and cost. S3 Glacier Deep Archive is too slow for retaining failed orders in a web application. Step Functions also may not be ideal for handling real-time orders.
Amazon S3 for web hosting, API Gateway for database API services, and SQS for queuing orders are scalable solutions. AWS Lambda handles business logic well with an SQS dead-letter queue efficiently retaining failed orders for further processing.
Amazon Lightsail is a simpler solution and lacks scalability for this type of architecture. SES is designed for email, not for queuing orders. Elasticsearch is more for search and analytics, not for retaining failed orders. EKS adds unnecessary complexity for small-scale applications.
