**Type:** Problem & solution

## Summary

Epsilon3 digitizes paper procedures and telemetry data for high-stakes space missions and complex operational testing. Operating in heavily regulated environments requires strict security, ITAR compliance, and flexible deployment options ranging from AWS GovCloud to on-premises installations. To meet these demands without sacrificing developer velocity, Epsilon3 deployed a self-hosted Supabase configuration running against an Amazon RDS Postgres instance on AWS. This architecture gives the team real-time data streaming capabilities over Postgres so operators can track live procedure changes as they happen. In addition to reducing DevOps complexity, self-hosting Supabase enables Epsilon3 to leverage Postgres Row Level Security while ensuring full compliance across diverse deployment environments.

## Context

Epsilon3 builds software to digitize procedures and telemetry data for space missions and other complex operations requiring high reliability and real-time collaboration. Because the space industry is heavily regulated, deployments often require ITAR compliance (such as via AWS GovCloud), in-country data residency, or on-premises deployment options.

## Approach / What changed

Epsilon3 deployed a self-hosted Supabase architecture on AWS, running the Supabase API to power an Amazon RDS Postgres instance. This architecture delivers real-time data streaming over Postgres for running procedures and simplifies the adoption of Postgres Row Level Security through client libraries.

## Takeaways

- Epsilon3 paired a self-hosted Supabase API on AWS with an Amazon RDS Postgres instance to balance rapid development with flexible hosting requirements.
- Supabase provided real-time functionality over Postgres, allowing operators to monitor updates and changes to running operational procedures as they happen.
- Self-hosting Supabase enabled Epsilon3 to meet strict regulatory mandates, such as ITAR compliance and on-premises or localized data residency needs.
