Summary

Build scalable property platforms with AWS serverless. Listing APIs, search engines, and notification systems with Lambda, API Gateway, and DynamoDB.

Key Facts

  • • Build scalable property platforms with AWS serverless
  • • Listing APIs, search engines, and notification systems with Lambda, API Gateway, and DynamoDB
  • • Search Performance: Property search must return results in under 500ms with complex filtering, sorting, and geo-spatial queries across millions of listings
  • • Image Delivery: Property listings average 20-30 images each
  • • Serverless Search API: API Gateway + Lambda + OpenSearch for property search with geo-spatial queries, faceted filtering, and relevance scoring

Frequently Asked Questions

Can serverless handle millions of property searches?

Yes. API Gateway scales to thousands of requests per second, Lambda handles search logic, and OpenSearch provides sub-second property search across millions of listings. ElastiCache caches popular searches for sub-50ms response times.

How do you handle real-time MLS updates?

Lambda functions poll MLS APIs or receive webhooks for listing changes. Updates flow through an event pipeline that updates DynamoDB, OpenSearch indexes, and triggers saved search alerts — all within minutes of MLS publication.

What does a serverless real estate platform cost?

A mid-size real estate platform with 500K listings and 1M monthly searches typically costs $2,000-$5,000/month on serverless. Costs scale linearly with searches and listing volume, and drop during off-peak months.

Key Challenges We Solve

Search Performance

Property search must return results in under 500ms with complex filtering, sorting, and geo-spatial queries across millions of listings.

Real-Time Listing Updates

MLS feeds push thousands of listing changes per hour — new listings, price changes, and status updates must be reflected immediately.

Market-Driven Traffic

Real estate traffic varies dramatically with interest rate changes, seasonal patterns, and market events.

Image Delivery

Property listings average 20-30 images each. Serving millions of high-quality images efficiently requires smart caching and optimization.

Our Approach

Serverless Search API

API Gateway + Lambda + OpenSearch for property search with geo-spatial queries, faceted filtering, and relevance scoring. ElastiCache for sub-50ms cached results.

Event-Driven Listing Pipeline

Lambda functions process MLS feeds in real time, normalize data, update search indexes, and trigger saved search notifications via EventBridge + SES.

Optimized Image Delivery

S3 for storage with Lambda@Edge for on-the-fly image resizing, WebP conversion, and CloudFront caching for fast global delivery.
