DevOps & Cloud

You're paying for servers to run APIs 24/7 when 90% of that compute is idle

We build serverless backends on AWS Lambda that scale from zero to millions of requests automatically — and cost nothing when idle.

The challenges you're facing

Server-based API infrastructure paying for compute at 3 AM when there are no requests — pure waste

Scaling events causing downtime because the server infrastructure can't handle traffic spikes automatically

DevOps overhead managing server patching, OS updates, and capacity planning for API infrastructure

Serverless APIs That Scale to Zero and to Millions

We architect and build serverless backends using AWS Lambda, API Gateway, DynamoDB (or RDS Proxy for SQL), SQS for async processing, EventBridge for event routing, S3 for storage, and Cognito or custom authorisers for authentication. We implement Lambda powertools for observability, structured logging, and distributed tracing. Infrastructure is Terraform-managed and deployed via CI/CD.

Lambda Function Development

Build Lambda functions in Python or Node.js with Lambda Powertools for logging, tracing, and error handling.

API Gateway & Auth Configuration

Configure API Gateway with routes, throttling, CORS, request validation, and authentication integration.

Deployment, Observability & Cost Baseline

CI/CD deployment, X-Ray tracing, CloudWatch dashboards, and initial cost analysis post-launch.

IoT Platform — 2M devices

Before

ECS-based API processing IoT events from 2M devices. Monthly compute cost: $8,200. Traffic highly variable: near-zero overnight, spikes of 50K req/min during business hours.

After

Migrated to Lambda + API Gateway + SQS. Lambda scales automatically from 0 to 10,000 concurrent executions. No idle compute cost.

Compute cost reduced from $8,200 to $1,100/month (87% reduction), zero capacity planning required, traffic spikes handled automatically with zero manual intervention

Frequently Asked Questions

Common questions from enterprise and mid-market teams across India and internationally.

What types of backends work well on AWS Lambda?

Lambda is excellent for: REST and GraphQL APIs with variable traffic, event-driven processing (S3 uploads, SQS messages, DynamoDB streams), scheduled jobs and cron tasks, webhooks, and image/document processing. It's less suitable for: long-running tasks (15-minute max execution), applications requiring persistent connections, very latency-sensitive workloads where cold starts are unacceptable.

How do you handle Lambda cold starts?

Cold start mitigation techniques: use Provisioned Concurrency for latency-critical functions (pre-warmed instances), optimise package size (Lambda initialisation time is proportional to package size), use Lambda SnapStart for Java functions (up to 10× faster cold starts), choose lighter runtimes (Node.js/Python vs Java for cold start sensitive paths), and avoid VPC-attached Lambda for non-private-resource functions.

Can Lambda connect to relational databases like RDS?

Yes, but connection management requires care. Lambda functions don't maintain persistent connections — each invocation may create a new DB connection. For high-concurrency Lambda, this causes connection pool exhaustion. We use RDS Proxy as a connection pooler between Lambda and RDS, which pools connections and dramatically reduces the number of actual DB connections.

What is the Lambda 15-minute timeout limit and how do we work around it?

Lambda functions terminate after 15 minutes maximum. For longer processing: break work into smaller units processed via SQS (each message processed by a separate invocation), use Step Functions for multi-step workflows that orchestrate Lambda functions with state, or use AWS Batch or ECS Fargate for genuinely long-running processes that don't fit Lambda's model.
