Axolo, an integration that streamlines code review processes, migrated from Heroku to Digital Ocean. However, one issue they faced was Digital Ocean Apps not supporting a static IP address, which is necessary for some enterprise servers requiring IP address whitelisting. To resolve this, Axolo considered two alternatives: transitioning to a Digital Ocean Droplet or setting up a reverse proxy server. They ultimately decided on the latter and chose to use a third-party service, QuotaGuard.com, due to its simplicity and effectiveness. This solution allowed them to maintain their server's integrity and security while providing a fixed IP address for enterprise communication.
