Ignition is an industrial software platform from Inductive Automation for building SCADA, HMI, MES, alarming, reporting and IIoT applications. It connects to SQL databases, to most PLCs through OPC UA or third-party OPC servers, and to MQTT and web services. Customers install Ignition on their own servers (Windows, Linux or macOS) and reach it through web-based clients; Ignition Edge serves remote sites. Ignition Cloud Edition runs on AWS or Azure and is sold through their marketplaces, but the vendor states that it is not SaaS: customers handle configuration, backups and upgrades themselves.
Inductive Automation is headquartered in Folsom, California, and is a US company; the software is proprietary, not open source. Because Ignition is normally installed on servers the customer chooses, a European organisation can keep operational data on its own infrastructure in the EU. The vendor's public pages do not describe EU hosting regions for Cloud Edition. Licences, updates and support still come from a US supplier.
