  • Encounter: RabbitMQ vs. Kafka – An Architect’s Dilemma

    For some reason, many developers view RabbitMQ and Kafka as interchangeable. The goal of this post is to present both RabbitMQ and Kafka side-by-side.

    • RabbitMQ is preferable when we need:
      1. Advanced and flexible routing rules.
      2. Message timing control (controlling either message expiry or message delay).
      3. Advanced fault handling capabilities, in cases when consumers are more likely to fail to process messages (either temporarily or permanently).
      4. Simpler consumer implementations.
    • Kafka is preferable when we require:
      1. Strict message ordering.
      2. Message retention for extended periods, including the possibility of replaying past messages.
      3. The ability to reach a high scale when traditional solutions do not suffice.

    s IT Solutions (currently Erste Digital) was the IT service company of Erste Bank Austria.

    I was in charge of architecture strategy, coordination and governance for the Branch & Lending division. During that time, I was actively involved in the company wide and division specific target architecture development and gap analysis.

    Analysis and providing insights into the current landscape from the logical, technical, and operational side plays a significant part.

    The challenge was to define the process and ensure the correct implementation of new, and reuse of existing products and platforms via architecture governance.

    Additionally, I was supporting strategic product and project development.

    As a generalist in the role of technical project manager, I was working with software projects from many perspectives – system integration, guiding the development, conceiving new solutions.

    Integrations of internal and external systems, scalability, system details knowledge, and having the big picture in mind all play a significant part in daily work.
