MQTT vs MSMQ: What are the differences?

MQTT vs. MSMQ: Key Differences

Introduction

MQTT and MSMQ are two popular messaging protocols used in the field of computer science and information technology. While both serve the purpose of enabling communication between distributed systems, there are several key differences that set them apart. In this article, we will explore these differences in detail.

  1. Communication Model: MQTT follows a publish-subscribe communication model, where messages are published by a sender and received by multiple subscribers. On the other hand, MSMQ follows a message queue model, where messages are sent to a queue and received by a single recipient. This fundamental difference in communication models determines how messages are distributed and received.

  2. Message Persistence: MQTT is known for its lightweight nature, and by default, it does not provide durable message storage. Messages are not persisted on the MQTT broker, and if a subscriber is not currently active, it will not receive messages that were published during its downtime. In contrast, MSMQ provides durable message storage, meaning that messages are persisted on the message queue and can be retrieved by the recipient even if it was offline at the time of message arrival.

  3. Message Routing: MQTT relies on a topic-based routing mechanism, where messages are published to specific topics, and subscribers subscribe to topics of interest. This allows for flexible and selective message distribution. On the other hand, MSMQ relies on direct message routing, where messages are sent directly to a specific queue and are retrieved by the recipient from that queue. This approach provides a more direct and targeted message delivery mechanism.

  4. Transport Protocol: MQTT is primarily built on top of the TCP protocol. It uses the TCP/IP stack for reliable and ordered message delivery. MSMQ, on the other hand, utilizes the Windows networking stack for reliable message transfer. This difference in transport protocols may have implications on aspects such as network overhead and compatibility with different operating systems and network environments.

  5. Platform Independence: MQTT is a platform-independent protocol, meaning it can be implemented on various operating systems and platforms. It is widely used in scenarios where there is a need for cross-platform communication. MSMQ, however, is a Windows-specific messaging technology and is tightly integrated with the Windows operating system. It offers advanced features and integration capabilities specific to the Windows environment.

  6. Standardization and Adoption: MQTT is an open standard protocol governed by the Organization for the Advancement of Structured Information Standards (OASIS). It has gained significant adoption in the Internet of Things (IoT) domain and has a thriving open-source community. MSMQ, on the other hand, is a proprietary technology developed by Microsoft and is primarily used in Windows-based enterprise systems.

In summary, MQTT and MSMQ differ in their communication models, message persistence, message routing mechanisms, transport protocols, platform independence, and standardization and adoption. Understanding these differences is crucial when choosing the right messaging protocol for your specific use case and system requirements.

What is MQTT?

It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.

What is MSMQ?

This technology enables applications running at different times to communicate across heterogeneous networks and systems that may be temporarily offline. Applications send messages to queues and read messages from queues.

What are some alternatives to MQTT and MSMQ?
RabbitMQ
RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received.
REST
An architectural style for developing web services. A distributed system framework that uses Web protocols and technologies.
XMPP
It is a set of open technologies for instant messaging, presence, multi-party chat, voice and video calls, collaboration, lightweight middleware, content syndication, and generalized routing of XML data.
Google Cloud Messaging
Google Cloud Messaging (GCM) is a free service that enables developers to send messages between servers and client apps. This includes downstream messages from servers to client apps, and upstream messages from client apps to servers.
Kafka
Kafka is a distributed, partitioned, replicated commit log service. It provides the functionality of a messaging system, but with a unique design.
