How does Cloudflare Workers differ from AWS Lambda for edge compute?

Cloudflare Workers runs JavaScript/WebAssembly at 300+ edge locations with sub-millisecond cold starts and no regional isolation, ideal for low-latency API transformations. AWS Lambda@Edge runs at CloudFront PoPs but is limited to specific CloudFront events and has stricter resource limits.

What are the main cold start challenges in serverless computing and how can they be mitigated?

Cold starts add 100ms–2s of latency when function instances initialize. Mitigation strategies include Provisioned Concurrency (AWS), minimum instance counts (Azure/GCP), keeping runtimes warm with scheduled pings, using lighter runtimes (Node.js, Python over Java/C#), and optimizing deployment package size.

How should enterprises handle stateful workflows in serverless architectures?

AWS Step Functions, Azure Durable Functions, and Google Cloud Workflows provide orchestration for stateful serverless workflows. These services manage long-running processes, retries, and parallel fan-out/fan-in patterns that are difficult to implement with stateless FaaS functions alone.
