Gateway Engine¶

Gateway Engine is a framework that eases the development of gateway applications. This page gives a brief introduction to what te Exosite Gateway Engine is. For more detailed documentation, please see the project’s readme file.

Key Features¶

It provides the following key features:

Application Hosting¶

Gateway Engine’s core feature is to provide a framework for your application/s to run in. This allows you to focus development efforts on just the business logic of your application.

Process Monitoring¶

Gateway Engine incorporates Supervisord to watch application processes and make sure that if they die, they will be restarted.

Application Logging¶

Gateway Engine captures all of an applications stdout and writes that to a log file. The Log files are automatically rotated and the oldest ones deleted, ensuring that your logs won’t fill up your disk space.

Bandwidth Usage and Monitoring (Beta)¶

If using the Exo-Python module, Gateway Engine can automatically watch your bandwidth for you and help make sure that you don’t have any unexpected costly cellular bills.

Warning

This feature is still in early beta and is still being tested.

Application Updates¶

Gateway Engine allows you to remotely update your application by using the Exosite Content Area.

Exosite Interface Module¶

Gateway Engine comes with a Python module that allows your application to easily communicate with Exosite.

Block Diagram¶

The following block diagram shows the basic pieces of Gateway Engine:

App Updater: Allows remote updates of applications.
Data Monitoring/NTP Update: Optional applications that are provided with Exosite. They are used to monitor your data usage and keep the system clock up to date.
Supervisord: Makes sure that applications start on boot and restarts them if they die.
Application 1/2: Your business application. You can have 1 or many applications running on in Gateway Engine.
Exosite Library: A Python library that is uses to track data usage as well as provide an interface for Python applications to use.
Node 1/2: Your node devices that are communicating with the gateway.
