GS.GRID

Multi-Server - MQTT broker, KissB enabled and more !

What is it

GRID Server is a multi-purpose, bus oriented, lightweight, industrial improved, server. It can work as a standalone server for presenting binary and Python service easely.

It is written in Pascal Object, currently compatible in delphi and FPC (Delphi post Unicode (2009+), FPC 3.04 (Arm) and FPC 3.3+ (Desktop class OS))

Binaries

Binaries for Windows (intel 32/64), Linux (intel 64, Arm32) is available in releases tab

History

• 20190924 | Added Sense Hat demo

• 20190920 | Release v1.0.0 Main targeted plaform (Win/nix - x86, x64, Arm) available

• 20190906 | add cpp binary API

Features

• KissB protocol : Bus Messaging protocol, shared a few common attributes with mqtt-protocol, but it is simpler (yes it can), and wider on its purpose)
• MQTT Broker
• Protocol Binding : rare feature Different Protocol can be server on the same port, ("negotiate" protocol steps).
• Key Value DB : In memory KeyValue DB is available, it use Bus capabilities to serve Key/Value number, string and stream data.
• Python Proxy : Run Python code directly on the server.

Compatibility

• For Features :
• MQTT Broker has been tested successully with
  • TMS MQTT Client
  • MQTT.fx tools
  • Chrome mqtt.box (websocket flavour)
• KissB protocol works currently with (incoming) native cpp and Python one, flawlessly.
• GRID Server work currently 24/24 in industrial area, local network area.

Features Status

• KissB Broker :

  • Message PUB/RCV/SUB/UNSUB : 100%
  • App Segregation on the same Bus HUB capabilities : 100%

Security consideration

• althought GRID Server is equiped for security, and ready to stuck to TLS/SSL2 security, this server is aimed to be a backend one, processing on "safe" area, not directly connected to the net.
• We have, at Grid System, build a secured level server which work directly on the net, please contact us if needed.
