Crosser

Crosser designs and develops streaming analytics and integration software for edge, on-premise or cloud. The Crosser platform enables real-time processing of streaming or batch data for Industrial IoT, data transformation, analytics, automation and integration. The Crosser platform consists of two core parts.

Crosser Cloud is the heart of the platform where all design and orchestration takes place. It is a multi-tenant SaaS service hosted by Crosser but also exists in an on-premise version that customers can run on a private cloud, inside the internal firewall.
Crosser Node is the real-time engine that customers install where they need it and anywhere a Docker container can be used.

Refer to the official Crosser homepage for more information on Crosser.
