I spent two months screen-sharing to ship one integration. So I rebuilt it on Temporal.

What this post added

This post details the construction of an egress-only, durable proxy application for cloud-to-edge messaging using Temporal. It replaces a complex, custom-built solution involving message queues, manual retry logic, and extensive testing with a simpler, more reliable Temporal-based architecture. The new system utilizes Temporal Workflows to manage configurations and an outbound connection from the edge device to Temporal for communication, eliminating the need for inbound firewall rules and manual debugging sessions. The author highlights the benefits of Temporal's durable execution, out-of-the-box reliability, and visibility in solving the challenges of integrating with firewalled edge devices.
