Implementing Multicloud Data Sharding with Hexagonal Storage Adapters

Short summary

Technical tutorial implementing multicloud data sharding with Hexagonal Architecture to handle GDPR and LGPD compliance requirements. The design decouples domain logic from cloud providers using storage ports and adapters, allowing transparent routing between AWS and Azure shards based on tenant metadata and region. Terraform manages infrastructure while Python/SQLAlchemy handles application logic, keeping the core domain agnostic of underlying cloud providers.

• •Multicloud sharding solves data residency and compliance fragmentation by routing tenant data to region-specific cloud providers
• •Hexagonal Architecture with ports/adapters decouples domain logic from storage, enabling seamless cloud-provider switching without code changes
• •Infrastructure-as-code (Terraform) plus Python/SQLAlchemy provides a practical, compliance-aware implementation pattern for distributed systems
