Implement serverless AWS architecture with Lambda functions and Bedrock Agent integration

[Copilot]

Implements serverless architecture for personalized LoL insights using AWS CDK, 3 Lambda functions, API Gateway, S3 storage, and Amazon Bedrock Agent orchestration.

Infrastructure (AWS CDK)

• S3 bucket: Versioned storage for match data with encryption and blocked public access
• API Gateway REST API: 3 endpoints with CORS (/api, /ingest, /tools)
• Lambda functions: Node.js 20.x runtime with appropriate timeouts (30s API, 60s Ingest, 30s Tools)
• IAM roles: Least-privilege access to S3 and Bedrock services

Lambda Functions

API Lambda (amplify/functions/api/)

Orchestrates Bedrock Agent invocations with streaming response handling. Falls back gracefully when agent unconfigured.

const command = new InvokeAgentCommand({
  agentId,
  agentAliasId,
  sessionId: sessionId || crypto.randomUUID(),
  inputText: query,
});

Ingest Lambda (amplify/functions/ingest/)

Validates and persists match data to S3 at match-data/{playerId}/{matchId}.json with metadata.

Tools Lambda (amplify/functions/tools/)

Provides 3 actions for Bedrock Agent: getPlayerMatches, getMatchDetails, getPlayerStats. Handles S3 NoSuchKey errors and JSON parsing failures.

Frontend

Interactive Next.js UI with tabbed documentation showcasing architecture components and API examples with request/response payloads.

Configuration

• bedrock-agent-config.yaml: OpenAPI 3.0 schema for Bedrock Agent action group configuration
• Backend integration via amplify/backend.ts creates custom CDK stack
• Deployment guide and architecture documentation included

Post-deployment requires configuring Bedrock Agent and updating Lambda environment variables with Agent ID/Alias.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• fonts.googleapis.com
  • Triggering command: /usr/local/bin/node /home/REDACTED/work/Rift-Rewind-Reviewer/Rift-Rewind-Reviewer/node_modules/next/dist/compiled/jest-worker/processChild.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
