Lambda costs $0.20 per 1M requests ($20) plus compute time. At 100M requests with 256MB memory and 100ms average execution, that's approximately $20 + $1,667 = $1,687/month. Cloudflare Workers costs $0.50 per 1M requests ($50) plus $12.50 per 1M CPU milliseconds. At 100M requests × 50ms average = 5B CPU milliseconds = $62.50, totaling $112.50/month. Workers is significantly cheaper for this scenario due to lower compute pricing, but Lambda wins if you need variable memory allocation (up to 10GB) or execution longer than 30 seconds."},{"question":"Can I run Python on both platforms?","answer":"Lambda supports Python natively with first-class runtime support, full standard library access, and ability to import popular packages (NumPy, Pandas, SciPy) via Lambda Layers. Cloudflare Workers supports Python only via WebAssembly (WASM) compilation, which is more complex and less performant. For Python workloads, Lambda is substantially better suited."},{"question":"Which platform is better for real-time APIs with global users?","answer":"Cloudflare Workers is significantly better for global real-time APIs due to sub-millisecond cold starts and execution on 275+ edge locations worldwide, delivering responses from geographically close servers. Lambda's 100-300ms cold start latency and 15+ regional data centers cannot match this for latency-sensitive applications. However, if your API requires database connections to a central location, network latency to that database becomes the bottleneck regardless of platform choice."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/aws-lambda-vs-cloudflare-workers))","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/aws-lambda-vs-cloudflare-workers))), AWS Lambda is a general-purpose serverless compute platform with broader AWS ecosystem integration and higher per-invocation pricing, while Cloudflare Workers is an edge-first platform with sub-millis","dateModified":"2026-07-09T12:20:56.799Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/aws-lambda-vs-cloudflare-workers))","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/aws-lambda-vs-cloudflare-workers))","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/aws-lambda-vs-cloudflare-workers))","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/aws-lambda-vs-cloudflare-workers))#claimreview","url":"https://www.aversusb.net/compare/aws-lambda-vs-cloudflare-workers))","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"AWS Lambda vs Cloudflare Workers","reviewBody":"AWS Lambda is a general-purpose serverless compute platform with broader AWS ecosystem integration and higher per-invocation pricing, while Cloudflare Workers is an edge-first platform with sub-millisecond latency and a simpler pricing model based on CPU time rather than invocations.","datePublished":"2026-07-09T12:20:56.732Z","dateModified":"2026-07-09T12:20:56.799Z","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"WebPage","@id":"https://www.aversusb.net/compare/aws-lambda-vs-cloudflare-workers))","url":"https://www.aversusb.net/compare/aws-lambda-vs-cloudflare-workers))","name":"AWS Lambda vs Cloudflare Workers","inLanguage":"en-US"}}}
