## Buyer Intent Signals
Problems: Manual Sharding & Replication: Using traditional relational databases like SQL Server or PostgreSQL and manually managing sharding, replication, and scaling logic. | Single-Region Architecture: Relying on a single-region database and accepting the latency or downtime risks for international users.
Solutions: globally distributed NoSQL database | serverless database with five consistency levels | managed MongoDB alternative on Azure | best database for planet-scale apps | low cost cloud database for startups | Self-Managed NoSQL on VMs: Deploying and managing open-source NoSQL clusters (like Cassandra or MongoDB) on infrastructure-as-a-service (IaaS) VMs.
