Lambda Kata
Eliminate AWS Lambda Cold Starts for Node.js
Integration Guide
Lambda Kata fits into your existing AWS setup as a runtime layer for Node.js Lambdas. Subscribe via AWS Marketplace, add the Lambda Kata package to your infrastructure-as-code projects, and mark which functions should use the optimized runtime—without changing their APIs, domains, or business logic.
Delivered as a Lambda Layer
Lambda Kata is delivered through AWS Marketplace and runs entirely inside your own AWS accounts. That means no external data paths or opaque proxies on your critical flows: your Node.js Lambdas execute where they always have, now with a runtime tuned for stability and latency-sensitive workloads.
Runtime Layer for Node.js
Lambda Kata acts as a runtime layer dedicated to performance and determinism for Node.js on AWS Lambda. Instead of wiring in yet another library, you configure Lambda Kata where runtime decisions actually belong: in your infrastructure definitions.
Full Control, No External Dependencies
You keep full control over your infrastructure and data. Lambda Kata runs within your AWS accounts under the same compliance controls as the rest of your AWS infrastructure. There are no external dependencies that sit in the middle of your critical flows.
Architecture Overview
Lambda Kata acts as a runtime layer between your application code and AWS Lambda infrastructure. It optimizes execution without requiring changes to your business logic or deployment workflows.
Works With Your Infrastructure Tools
Adopting Lambda Kata feels like introducing a new, higher-grade runtime for a subset of your Node.js functions. The integration is done at the infrastructure-as-code level, so your CI/CD pipelines stay familiar while your most critical Lambdas shift to a deterministic performance profile.
AWS CDK
Add the Lambda Kata layer to your CDK stacks with a simple construct. Platform teams decide which Lambdas should run on the optimized runtime, and application teams keep writing code as usual.
SST
SST users can integrate Lambda Kata through the standard layer configuration. Your existing SST project structure remains unchanged while gaining deterministic runtime behavior for selected functions.
Serverless Framework
Configure Lambda Kata in your serverless.yml to apply the optimized runtime to specific functions. The familiar Serverless Framework workflow continues to work exactly as expected.
AWS Marketplace Subscription
Lambda Kata integrates with AWS Marketplace for billing, so procurement and financial tracking follow the same patterns you already use for other cloud software. There are no hidden clusters, extra infrastructure, or separate contracts—just a focused runtime product billed through familiar AWS mechanisms.
Usage-Based Billing
Lambda Kata uses a usage-based model aligned with how you already think about AWS Lambda: per invocation. You pay based on the invocations that run through the optimized runtime, not on how many functions you have declared or how many teams use them.
Scales With Your Adoption
Because Lambda Kata runs inside your AWS accounts and follows a usage-based model, it scales naturally with your adoption. Start with a small scope and expand as you see the impact on performance, incidents, and business outcomes, without renegotiating contracts.
Incremental Path to Production
The path to production with Lambda Kata is incremental. Start with one or two high-value Node.js Lambdas, observe the impact on latency and incident patterns, and then roll out the runtime to a wider set of services once you're comfortable with the behavior and operational model.
Platform Teams Decide
Platform teams decide which Lambdas should run on the optimized runtime, and application teams keep writing code as usual, benefiting from the improved behavior automatically. No code changes required in your business logic.
Familiar CI/CD Workflows
The integration is done at the infrastructure-as-code level, so your CI/CD pipelines stay familiar. Deploy Lambda Kata alongside your existing deployment processes without disrupting established workflows.
