AWS Certified Solutions Architect Associate SAA-C03 Practice Question

Utilizing Amazon SQS to decouple the job submission from the processing allows the company to handle workload spikes without the need for immediate processing, as jobs can be stored in the queue. The auto-scaling group can then process jobs from the queue based on demand, scaling out to handle more jobs as needed and scaling in when demand decreases. This approach offers a resilient distributed system that can handle variable loads effectively. Implementing a straight serverless approach using AWS Lambda might face limitations due to the execution duration limit, which could be inadequate for long-running transcoding tasks. On the other hand, a single EC2 instance would not provide the necessary scalability and could become a bottleneck during spikes. Lastly, Amazon S3 is not a processing service but rather object storage, so using it alone would not fulfill the transcoding requirements.
