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
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.
