How AWS Lambda Works
Microvm-based execution using Firecracker with per-invocation isolation, supporting multiple runtimes and container images
Key Use Cases
- API backends and webhooks
- Event-driven data processing
- Scheduled tasks and cron jobs
- Real-time file and stream processing
When to Use AWS Lambda
AWS Lambda is a strong choice when your project requires API backends and webhooks, Event-driven data processing, Scheduled tasks and cron jobs. AWS Lambda scales to thousands of concurrent executions with cold starts ranging from 100ms to several seconds depending on runtime and package size.
