AWS Lambda runs code without managing servers, charging only for compute time used.
- for
- Developers building event-driven, web, or isolated compute workloads.
- pricing
- paid
Key features
- Event Functions — Run code triggered by over 220 AWS services with automatic scaling and pay-per-use billing.
- Web Functions — Deploy standard Node.js HTTP servers globally with multi-region routing and active CPU billing.
- MicroVMs — Execute code in isolated sandboxes with state retention and lifecycle control.
- Managed Instances — Dedicated EC2-backed capacity for compute-intensive jobs with longer timeouts.
- Durable Functions — Orchestrate long-running, multi-step workflows with built-in branching and retries.
- Real-time Processing — Process streaming data from Kinesis, Kafka, SQS, and DynamoDB Streams with sub-second latency.
Use cases
- Serve full-stack web apps with global low-latency endpoints
- Process event streams and batch jobs at any scale
- Run isolated tenant code or third-party plugins securely
- Orchestrate AI agent workflows and durable business processes
- Handle high-throughput data pipelines with dedicated Managed Instances

- AWS Lambda vs Cloudflare Workers: Runs serverless code on Cloudflare’s edge network, focused on global low-latency edge execution.
- AWS Lambda vs Vercel: Provides a frontend-focused platform for building and deploying web apps, not a general compute service.
- AWS Lambda vs Render: Offers managed app hosting with containers, but requires more infrastructure management than Lambda’s pure functions.
- AWS Lambda vs Replit: Browser-based development environment with AI assistance, not a cloud compute service.
AWS Lambda FAQ
How do I choose between Event Functions, Web Functions, and MicroVMs?+
Event Functions suit discrete event sources, Web Functions run standard HTTP servers natively, and MicroVMs provide VM-level isolation and state retention.
When should I use Lambda Managed Instances?+
Use Managed Instances for compute-intensive workloads like large data processing, media transcoding, or scientific simulations that need dedicated capacity and longer timeouts.
What billing model does Lambda use?+
Lambda uses a pay-as-you-go model, charging only for the compute time your code actually consumes.
Can I run untrusted code with Lambda?+
Yes, MicroVMs offer VM-level isolation with no shared kernel or memory, suitable for untrusted or third-party code.
