Pay zero for idle infrastructure.

AWS serverless development means building applications using managed services like Lambda, API Gateway, and DynamoDB where AWS handles all server provisioning, scaling, and maintenance. You write business logic, deploy it, and pay only when your code runs. No servers to patch, no capacity to plan, no idle resources burning money.

Most teams see 60-80% cost reduction compared to traditional EC2-based architectures. The savings come from pay-per-request pricing (no idle costs), zero operations overhead (no sysadmins needed), and automatic scaling that matches actual demand. A workload costing $5,000/month on EC2 often drops to $800-1,500/month on serverless.

Yes. AWS Lambda scales to thousands of concurrent executions automatically. API Gateway handles millions of requests per second. DynamoDB offers single-digit millisecond reads at any scale. We have built serverless systems processing 50M+ requests per day without performance issues.

Absolutely. We follow a strangler fig pattern, migrating one component at a time so you get incremental benefits without big-bang risk. We start with the highest-ROI services (usually APIs and background jobs), prove the savings, then migrate more. Most migrations complete in 4-8 weeks.

Cold starts are manageable and often overstated. For most APIs, cold starts add 100-300ms on the first request. We use provisioned concurrency for latency-sensitive endpoints, keep functions lean, and choose runtimes like Node.js or Python that initialize fast. For 95%+ of use cases, cold starts are a non-issue.

We use AWS CDK (TypeScript) as our primary IaC tool for serverless projects. CDK provides type-safe constructs purpose-built for Lambda, API Gateway, and DynamoDB, making deployments faster and more reliable. We also work with Terraform and SAM if your team already has an established workflow.
