Message Queues: reliable message transmission

If asynchronous and scalable communication between different systems and components is required, message queues are used. The middleware ensures that message requests are buffered in the queue until the recipient retrieves them - so no information is lost. Extensive processing processes are decoupled with message queues and applications become more reliable, flexible and scalable.

Message queues play an important role in

  • Microservice architectures
  • Big Data
  • Internet of Things (IoT)

Technologies in the field of message queues

As experts for distributed systems, we are also very familiar with the various message queues that are used in modern architectures.


Kafka is an open source streaming platform used for processing streams of data and real-time news. It is particularly useful for big data applications and is used by companies around the world to process and analyze large amounts of data in real time.


RabbitMQ is a message broker. It supports various messaging protocols such as AMQP, MQTT and STOMP and offers a robust and flexible architecture for exchanging messages between different systems.


Amazon SQS stands for “Simple Queue Service” and is a managed service from Amazon. SQS is scalable, robust and supports various communication protocols.

Better performance thanks to message queues

Message queues can be integrated into company software landscapes in various ways. This can happen internally and within an operating system or an application, for example. The most common implementation options include proprietary solutions, cloud-based solutions, open source solutions, hardware-based solutions. As an Apache Kafka Confluent Partner, we bring deep expertise in open source options from the Apache environment that are suitable for messaging middleware systems. Our focus here is particularly on areas of application with high performance and speed requirements, such as e-commerce.

## Communication between components: Message queues have many advantages If several systems are in use, message requests are constantly being sent between them. Message queues help to reduce workflows in modern software architectures. Other benefits include:
decoupling iconAn illustration of decoupling icon

Simple decoupling

Components within a system do not have to communicate with each other directly, but use a common message queue for this.

Transmission Security

Message queues provide reliable transmission of messages. These are also transmitted in the correct order and in a secure format.

scalability iconAn illustration of scalability icon

Better scalability

By decoupling components, systems are more scalable. If the volume of messages increases, additional components can be added quickly.

availability iconAn illustration of availability icon

Higher availability

By decoupling components, systems are more scalable. If the volume of messages increases, additional components can be added quickly.

fault tolerance iconAn illustration of fault tolerance icon

Greater fault tolerance

Messages remain in the queue until another component processes them. That way no data is lost.

flexibility iconAn illustration of flexibility icon

More flexibility

Message queues can be used in many different ways in distributed systems and can be integrated with various programming languages.

Frequently Asked Questions

How to monitor and optimize message queue performance?

In order for message queues to perform at their best, the technology must match the requirements of the systems. There are several ways to optimize performance. This includes grouping messages, scaling the message queue, using load balancing and having sufficient storage capacity available.

How to fix message queue errors?

In order for errors in message queues to be corrected, the cause must first be identified. Measures such as regular monitoring are helpful and can be used preventively. Backups and emergency recovery plans should also be created to ensure a high level of reliability.

Message queues in distributed systems

Message queues support communication and coordination in distributed systems. The components are often divided between data centers or clouds. Message queues allow messages to be sent and received without the components being directly connected to each other. Message queues provide a reliable and scalable system for passing messages between different systems and applications.

Message Queues or Apache Kafka?

Message queues and Apache Kafka are important technologies when it comes to processing data streams and extracting real-time insights. Depending on the application and requirements, a decision is made as to which of the two technologies is more suitable.
