From Chaos to Flow - How Kafka, Camunda, and Cell Design Work Together

Let me tell you a story. Imagine you’re running a decentralized organization inspired by Betacodex principles. Your teams (or "cells") are autonomous, self-organized, and laser-focused on delivering value. But as your organization grows, so does complexity. Processes start to overlap, communication slows down, and suddenly, your once-agile cells feel more like a tangled web. This is where Kafka, Camunda, and the right process design patterns come into play. Let’s dive into two process diagrams and explore how they can help you regain clarity, speed, and flow.

The Two Diagrams: A Tale of Simplicity vs. Complexity

Diagram 1: The Basic Flow
Diagram 1: The Basic Flow

This diagram is like a straightforward to-do list. Tasks are connected in a clear sequence, with decision points (XOR gateways) guiding the flow. Each swimlane in this process represents a team or role.

But here’s the catch:

  • Communication between tasks is implicit.

  • It assumes everyone knows what to do next without needing to talk.

  • It works great for simple, linear processes, but what happens when things get more complex?

Now, imagine you’ve added Kafka to the mix. This diagram explicitly models message flows (those cute envelope icons 📩). Tasks don’t just pass the baton—they send events through Kafka topics, ensuring everyone gets the memo.

Here’s why this matters:

  • Communication is explicit, making it easier to track who’s talking to whom.

  • It’s perfect for event-driven architectures, where tasks trigger each other asynchronously.

  • It aligns beautifully with Camunda, which can orchestrate workflows while Kafka handles the streaming.

💡 Did you notice the left side of the swim lane here? It is also split in three parts - this means we have in reality three autonomous processes instead of one!

Kafka + Camunda: The Dynamic Duo

Think of Kafka as the nervous system of your organization. It connects all the cells, ensuring they can exchange information in real time. Meanwhile, Camunda acts as the brain, orchestrating workflows and making sure everything happens in the right order.

Here’s how they work together:

  1. A task in Camunda triggers an event and publishes it to a Kafka topic.

  2. Another task (or even another cell) listens to that topic and starts its process.

  3. Kafka ensures that events are decoupled, meaning tasks don’t need to know about each other directly.

In real life, think of Camunda tasks as complex sub flows, and Kafka topics as Streaming Data Products which can act as the go-to-place for specific data needs.

Cell Design: Why This Matters

In a Betacodex-inspired organization, cells are designed to be autonomous. But autonomy doesn’t mean isolation—it means interdependence without bottlenecks.

  • Diagram 1 works for independent cells with minimal communication needs. For example, a team that handles a self-contained process.

  • Diagram 2 is essential for interconnected cells. When one cell finishes its task, it sends an event through Kafka, triggering another cell to act. This ensures smooth collaboration without micromanagement.

A Real-World Example

Let’s say you’re running an e-commerce platform. Here’s how the diagrams play out:

Diagram 1: Basic Flow

  • A customer places an order.

  • The order is processed, and the warehouse is notified.

  • The warehouse ships the product.

This works fine for a small operation, but what if you need to scale?

Diagram 2: Communication-Enhanced Flow with Kafka

  • The customer places an order. Camunda triggers an event to Kafka (e.g., OrderPlaced).

  • The warehouse listens to the OrderPlaced topic and starts preparing the shipment.

  • Meanwhile, the billing system listens to the same topic and processes the payment.

  • If the warehouse finishes first, it sends an OrderShipped event, which triggers a notification to the customer.

Now, tasks are happening in parallel, and your system is both scalable and resilient. And, you just added asynchonicity which means you can model your flows in a way that they react to unplanned intermediate events - this is where basic flows most often fail in real life!

Key Takeaways

🌟Diagram 1 is great for simplicity but struggles with complexity.

🌟Diagram 2 shines in dynamic, event-driven environments where communication is key.

🌟Pairing Kafka with Camunda creates a powerful system for managing workflows in a decentralized, scalable way.

🌟In a cell-based organization, explicit communication ensures autonomy doesn’t lead to chaos.

What’s Your Flow?

As your organization grows, so does the need for better process design. Whether you’re building workflows for autonomous teams, orchestrating tasks with Camunda, or scaling with Kafka, the right diagram can make all the difference. What challenges are you facing in your processes?
