Typical PTAnywhere installation - PTAnywhere/ptAnywhere-installation GitHub Wiki
A PTAnywhere installation looks like the following image shows.
There is a web server where the PTAnywhere API is deployed. Additionally, it might also serve the web application with the HTML widgets which use the API. The PTAnywhere API uses a database to handle students' sessions. It also relies on one or more PT managers to handle Packet Tracer instances. Each manager can handle several concurrent instances. Optionally, the API can also record interaction details in a Learning Record Store (LRS).
