Hi Hasitha, Thank you for this clear response.
Apparently it seems difficult with WSO2 MB or any multi-protocol broker (https://stackoverflow.com/questions/27884895/what-are-the-maximum-mqtt-connections-supported-by-activemq-5-10-0). In this case it remains only pure MQTT middleware (among (https://github.com/mqtt/mqtt.github.io/wiki/servers). Mosquitto performance (~20,000 connections per instance) is great but It has bridge feature but not a "real" clustering (https://groups.google.com/d/msg/mqtt/sFjCBovLavw/9jKFLiEaBwAJ). The 1.0 release of the EMQ broker has scaled to 1.3 million concurrent MQTT connections on a 12 Core, 32G CentOS server (https://github.com/emqtt/emqttd) The performance is not the only criterion because it is also necessary to check the non-loss of messages (https://vernemq.com/docs/clustering/netsplits.html#possible-scenario-for-message-loss) Thanks Youcef HILEM -- Sent from: http://wso2-oxygen-tank.10903.n7.nabble.com/WSO2-Architecture-f62919.html _______________________________________________ Architecture mailing list Architecture@wso2.org https://mail.wso2.org/cgi-bin/mailman/listinfo/architecture
