Is MQTT based on HTTP?
MQTT is data centric whereas HTTP is document-centric. HTTP is request-response protocol for client-server computing and not always optimized for mobile devices. Besides, publish/subscribe model provides clients with independent existence from one another and enhance the reliability of the whole system.
Is MQTT more secure than https?
This protocol has many features as it is over TCP and uses SSL/TLS for security. For messaging between server it uses CONNECT, PUBLISH, SUBSCRIBE, DISCONNECT, etc….Difference between MQTT and HTTP protocols :
| Parameter | MQTT | HTTP |
|---|---|---|
| Data Security | It provides data security with SSL/TLS. | It does not provide security but Https is built for that. |
What is the advantage of MQTT over HTTP?
Why MQTT over HTTP?
| MQTT | HTTP |
|---|---|
| The connection is always open between broker and client | Open and close the connection every time for each request |
| Low power consumption | Higher power consumption |
| Mainly useful for sending short messages. | Mainly useful for sending lengthy messages. |
Why HTTP is not suitable for IoT?
As more sensor devices are added in the network, the load on the server increases. If the sensor devices themselves are connected to multiple other devices, this puts heavy load on the tiny system resources of the sensors. Hence, HTTP does not scale well for IOT applications.
Is MQTT is better than HTTP for sending and receiving data?
MQTT is better than HTTP for sending and receiving data. Explanation: MQTT is a lightweight protocol that runs on top of the TCP/IP protocol and works with publish subscribe mechanism.
Is HTTP good for IoT?
HTTP was designed for a request-response based communication rather than a event-driven communication. Also, programming this event based systems using HTTP protocol becomes a big challenge especially because of the limited computing resources on the sensor devices. Hence, HTTP does not scale well for IOT applications.
Is Kafka good for IoT?
Kafka still brings a lot of value to IoT use cases. IoT solutions create large amounts of real-time data that is well suited for being processed by Kafka.
How is Kafka different from MQTT?
In terms of the difference between mqtt-based message broker and Kafka, Mr. Kafka focuses on the storage and reading of data, aiming at streaming data processing scenarios with high real-time performance, while MQTT broker focuses on communication between client and server.
Does IoT use HTTP?
• HTTP (HyperText Transfer Protocol) HyperText Transfer Protocol is the best example of IoT network protocol. This protocol has formed the foundation of data communication over the web. It is the most common protocol that is used for IoT devices when there is a lot of data to be published.
