Strengthened AWS infrastructure security and reduced network latency

We have finalized a multi-week project focused on AWS infrastructure, targeting both security and performance.

Key improvements include:

• Expanded use of AWS VPC: All service-to-service traffic now runs entirely over internal networks instead of the public internet, strengthening data security.

• Optimized front-end ↔ back-end connections: Introduced new connection setups with internal routing and long keep-alive sessions, ensuring sockets remain open for faster request handling and reduced overhead.

These changes deliver a dual benefit: a more secure environment by minimizing exposure to the public internet, and better performance through reduced latencies in core service communication.

For security reasons, the full scope of the work is not publicly disclosed, but the examples above illustrate the scale of the improvements.
