Starting with version 8.0, all communications between clients and the Gurobi Instant Cloud use the HTTPS protocol. This means that your communications are secured and encrypted using standard internet protocols. In addition, Gurobi servers enforce the latest encryption policies (TLS v1.2 and above only). For better security, the dedicated machines started by Instant Cloud on your behalf cannot be accessed directly. All communications must transit through a secured and highly-available region router acting as a reverse proxy. This also facilitates the integration with clients, as only the standard HTTPS protocol and standard port 443 need to be open if a firewall is in place.
The region router is automatically detected and used based on the pool definition or the machine license file.
