10. **VPC endpoint costs**: Interface endpoints for SQS, Bedrock, and Secrets Manager cost ~$7/mo each per AZ. In a 2-AZ prod setup, that's ~$40-50/mo fixed cost. Acceptable for a production SaaS, but worth tracking — may influence which services we use in early phases (e.g., defer Bedrock endpoint until premium tier ships).

10. **VPC endpoint costs** (resolved): SQS and Bedrock interface endpoints have been eliminated by switching to DynamoDB Streams (for async reindexing) and local MiniLM embeddings (for semantic search). The only remaining interface endpoint is Secrets Manager (~$7/mo/AZ, introduced in Phase 4). See [[Design/Async_Embedding_Pipeline]].
