Lambda's 15-minute timeout accommodates batch jobs and complex workflows. Choose Lambda for backend APIs requiring sustained compute power."},{"question":"When should I use Cloudflare Workers over AWS Lambda?","answer":"Use Cloudflare Workers for globally distributed, low-latency applications requiring <50ms response times—such as real-time APIs, request routing, DDoS mitigation, and webhook handlers. Workers excel when you need automatic worldwide distribution without regional configuration. Choose Workers for rate limiting, caching, and edge-side security logic."},{"question":"What's the cost difference for a typical web API with 10M requests/month?","answer":"For a lightweight API (100ms execution, 256MB memory), Lambda costs ~$18-25/month while Cloudflare Workers costs ~$2.50/month on the Workers Paid plan. Workers' edge execution model and global distribution eliminate regional provisioning costs. Lambda becomes cheaper only for long-running functions (500ms+) where Workers' 50ms limit forces rejection."},{"question":"Can I use both Lambda and Workers together?","answer":"Yes. Deploy Workers as a global edge layer for routing, caching, and DDoS protection, then route qualifying requests to Lambda for complex backend logic. For example, use Workers to validate and rate-limit requests, then forward to Lambda for database operations. This hybrid approach minimizes Lambda cold starts by filtering at the edge."},{"question":"Which has better multi-region failover?","answer":"Cloudflare Workers automatically serves from the nearest of 275 data centers with built-in redundancy—no configuration needed. AWS Lambda requires manual setup across multiple regions with Application Load Balancer or Route 53 failover policies. Workers' automatic edge distribution makes it superior for multi-region resilience out-of-the-box."}],"faqPageSchema":{"@context":"https://schema.org","@type":"FAQPage","@id":"https://www.aversusb.net/compare/aws-lambda-vs-cloudflare-workers)#faq","url":"https://www.aversusb.net/compare/aws-lambda-vs-cloudflare-workers)","inLanguage":"en-US","name":"AWS Lambda vs Cloudflare Workers — FAQ","description":"Frequently asked questions about AWS Lambda vs Cloudflare Workers","dateModified":"2026-07-07T21:52:13.690Z","author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"publisher":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"isPartOf":{"@type":"Article","@id":"https://www.aversusb.net/compare/aws-lambda-vs-cloudflare-workers)#article"},"license":"https://creativecommons.org/licenses/by/4.0/","speakable":{"@type":"SpeakableSpecification","cssSelector":["#faq",".faq-item"]},"mainEntity":[{"@type":"Question","name":"When should I use AWS Lambda over Cloudflare Workers?","acceptedAnswer":{"@type":"Answer","text":"Use AWS Lambda when you need execution times longer than 50ms (e.g., ML inference, database queries, data processing), memory above 50MB, or tight integration with AWS services like RDS/DynamoDB.
