Difference : AMQP(Advanced Message Queuing Protocol) and MQTT(Message Queuing Telemetry Transport)

Updated: Jan 10, 2022

AMQP: Advanced Message Queuing Protocol

The Advanced Message Queuing Protocol (AMQP) is an open standard for passing business messages between applications or organizations. It connects systems, feeds business processes with the information they need and reliably transmits onward the instructions that achieve their goals.

Advantages:

Has built-in integrations for TSL and SASL for greater security
Supports many different messaging patterns
Offers three levels of QoS for message deliverability and reliability.
Can be extended very easily.
Has many open-source libraries to make implementation easy

Disadvantages:

Requires higher bandwidth compared to MQTT.
Has bigger messages which means slower transmission speeds.

MQTT: Message Queuing Telemetry Transport

MQTT is a lightweight, publish-subscribe network protocol that transports messages between devices. The protocol usually runs over TCP/IP, however, any network protocol that provides ordered, lossless, bi-directional connections can support MQTT.

Advantages:

Its lightweight and battery-friendly.
Offers 3 QoS levels to support reliable messaging
Works well over unreliable networks
Allows for security through TLS.
Has Many open-source libraries to ease development and implementation.
Low bandwidth usage.

Disadvantages:

Only supports the publish-subscribe messaging pattern
Not as easily extensible compared to AMQP.
Less built-in security features compared to AMQP.

Difference Between AMQP and MQTT

AMQP MQTT

AMQP offers a wealthier range of messaging circumstances.	It offers a simple way of message queuing services and it is implemented mostly in the embedded systems.
AMQP is developed by finance groups as an open-source and customer-driven queue. It is improving day by day in the market without any customization.	MQTT is mostly vendor-driven and developed by IBM with high implementation costs.
AMQP uses TCP for the asynchronous transfer of messages regardless of any selection of OS, Hardware or programming language. It offers a messaging service with complete vitality. AMQP is operated within parties under varied control of network user and infrastructure resources.	Similar to AMQP, MQTT uses TCP for the sharing of messages in an asynchronous method independent of any attributes. It is specially designed for small devices operating on minimum bandwidth of the network. MQTT sees the intricate parties as managed by the nearby private infrastructure.
It is advanced optimized on the wire of data framing which has a buffering approach that increases performances of the server.	It is also based on the wire framework which uses stream like approach to execute frames for minimum memory devices. It doesn’t allow the transfer of bulk messages.
AMQP is applied in five varied attributes such as publisher-subscriber not affected lifetime, as long as it required it remains in queue and stays still if none is using the queue. It enables all kinds of messaging round-robin, classic or traditional message queue, combinations, and save and forward. It executes meta-data message to help idempotent messages and grouping of messages.	It is based on publishing and subscribe messaging to the content and is highly transient. It is mostly engaged for active routing of consequently linked subscribers and publishers. It is limited to apply in traditional extended life message queuing.
It supports different acknowledgment, transactions, use cases along with the entire message queues. It enables the disintegration of varied transactional codes and that is required and acknowledges as expired when there is a delay to fine-tune the performance.	MQTT doesn’t support any kind of transaction. It supports only general acknowledgments.
AMQP is unified with TLS and SASL and secured with special features to use the connection. It is developed with the ability to eliminate the policy of SASL and TLS and increase the performance with continuous updates	MQTT doesn’t act to any security issues in connection.
AMQP utilizes SASL methods to select security without any change in protocol. It provides different names for the components in the same networks. So this feature enables us to use nested firewalls and gatekeepers. It will authenticate with the user before broadcasting any messages.	MQTT needs small user names and minimum passwords and does not set any preventive measure in this trending period.
It doesn’t support the last values in the queue.	It provides Retain command and support the last value in the queue.
It enables only fire and forgot policy. Once received cannot be retrieved.	It is similar to AMQP and data delivery is too reliable.
It allows multiple ways in finding messages such as nodes and queues.	It uses “namespaces” in a hierarchical transmission of messages.
AMQP supports peer to peer connection and allows load balancing for the entire network and it is multiplexing. it can use containers and the topics are bisymmetric.	MQTT offers basic requirements for the DNS server. MQTT is asymmetric and doesn’t support any advanced features.
AMQP is implemented in components of less than 64kb of RAM.	It is a smaller protocol in open source libraries and is implemented in devices less than 64kb of RAM
It has structure points that allow extensibility in a specific vendor and agrees to the upcoming extension incompatible way. It allows alteration in layers by isolation.	MQTT needs an entire fresh draft of the protocol.
