Resilient and Decoupled Cloud Architectures

Assess how to decouple application tiers during unexpected traffic spikes:

Domain 2: Resilient Architectures Sample Question 1 of 1
An e-commerce company experiences unexpected traffic surges during flash sales. The web application runs on EC2 instances behind an Application Load Balancer and writes orders directly to an RDS MySQL database, which crashes due to connection exhaustion. Which decoupled architecture should the solutions architect implement to absorb order traffic without losing transactions?
A
Manually upscale the RDS instance size right before every promotional flash sale.
B
Introduce an Amazon SQS queue between web servers and an Auto Scaling worker tier that processes orders asynchronously into RDS.
C
Configure an Amazon S3 bucket as the primary transactional ACID database.
D
Replace the ALB with a single Elastic IP attached directly to an oversized EC2 instance.
✓ Official Explanation: (B) Amazon SQS decouples the web tier from the database tier, buffering burst traffic in the queue while consumers process requests at a sustainable rate for the RDS MySQL database without dropping transactions or exceeding connection pools.
