AWS IoT Message Broker
MESSAGE BROKER
Communicate with devices via
MQTT and HTTP
AWS IoT
Message Broker
Standard Protocol Support (no lock-in)Millions of devices and apps can connect over any protocol starting with MQTT and HTTP 1.1
Long-lived bi-directional messages Clients (Devices and Apps) can receive commands and control signals from the cloud
Secure by Default
Connect securely via X509 Certs and TLS
1.2 Client Mutual Auth
Topic Based Architecture (lights/thing-2/color)
Highly Scalable Message Broker
MQTT
MQTT vs HTTPS:•93x faster throughput
•11.89x less battery to send •170.9x less battery to receive
•50% less power to keep connected •
8x less network overhead

•OASIS standard protocol (v3.1.1)•Lightweight, pub-sub, transport protocol that is useful for connected devices •MQTT is used on oil rigs, connected trucks, and many more sensitive and resource-sensitive scenarios.•Customers have needed to build, maintain and scale a broker to use MQTT with cloud applications
