Squirro is designed and optimized for Linux. Installations are provided for the Red Hat® and CentOS distributions, both in the cloud or on premise.

Squirro is built as a service-oriented platform. All services work as self-contained units of functionality and therefore are suited for different scenarios. Squirro can match small but also complex and large-scale requirements. All Squirro services communicate via RESTful API. The Squirro API is open and allows for 3rd party integration for all services and functionality.

Versions

Squirro supports two different types of deployments - cloud and on-premise. Updating installations in the cloud is done by the Squirro staff, based on individual agreements with the customer. For on-premise deployments, the upgrade process is driven by the customer directly.

Please see the Release Notes section for details about individual releases or reach out to Squirro Support about scheduled upcoming release dates.
