Planning staff upload permit-plan PDFs to a records bucket, and the current monolith blocks the upload thread while it generates thumbnails on an always-on EC2 worker. Which serverless enhancement should architects select?
Select an answer to reveal the explanation.
Short Explanation
Don't make the front counter wait while someone photocopies a thumbnail. Drop the PDF in S3, let Lambda wake up, and keep the upload snappy. An always-on worker for a burst of PDFs is overtime nobody needs.
Full Explanation
Event-driven serverless is a core Task 4.4 opportunity. Amazon S3 object-created events can invoke AWS Lambda to generate thumbnails asynchronously, decoupling the upload path from CPU-heavy image work and eliminating an always-on EC2 worker. Polling workstations, jump-host processes, and synchronous generation on the upload API miss that modernization.
