Cloud Sync
OtterSync
Real-time multi-cloud data synchronization and state management
Overview
OtterSync provides resilient bidirectional synchronization across cloud storage, local filesystems, and databases. Features conflict-free replicated data types (CRDTs), end-to-end encryption, and delta-compression for instantaneous sync over low-bandwidth networks.
Key Architectural Highlights
Real-Time Bidirectional Sync
Continuous file and database record synchronization with sub-second event propagation.
CRDT Conflict Resolution
Mathematical merge guarantees eliminating lost data and manual conflict resolution.
End-to-End Encryption
Zero-knowledge client-side encryption ensuring your synced data cannot be read by any relay server.
Delta Chunk Compression
Only modified binary diffs are transmitted across the network, saving up to 90% bandwidth.
