Cisco IOx Application Framework
Cisco IOx is an end-to-end application framework that merges Cisco IOS-XE with Linux to offer secure hosting for applications on Cisco network platforms. This integrated framework allows the deployment of applications directly within the network infrastructure and provides secure management through Cisco application hosting tools.
From Cisco IOS XE Cupertino 17.8.1, Cisco Catalyst IE9300 Rugged Series Switches support IOx application hosting. This feature allows you to run your custom code, applications, and containers directly on the Cisco Catalyst IE9300 Rugged Series Switches.
See Cisco IOx page for more information.
