Experience the Power of Workflow Engines in Kubernetes
La Rebelion Labs
In today's fast-paced digital world, businesses are constantly looking for ways to streamline their operations, reduce manual errors, and improve efficiency. This is where a workflow engine comes into play. Workflow engines are powerful tools that help automate routine tasks, ensuring that processes are executed consistently and efficiently. When combined with Kubernetes, a popular container orchestration platform, workflow engines can take your business operations to the next level.

Did you know that the CI/CD pipelines and routine tasks were not other things than workflows? Stating the obvious, workflows are not just about automating CI/CD pipelines and routine tasks but also about modeling complex business processes. Let's dive deeper into the world of workflows, understand why they are popular in sectors like banking and eCommerce, and explore how enterprises are leveraging workflow engines to implement business rules and drive efficiency even much before the CI/CD tooling started to be a thing, and even before Git, GitOps, and DevOps were born.
Understanding Workflow (BPMN)
Understanding how different business processes interact can significantly enhance operational efficiency and collaboration. Business Process Model and Notation (BPMN) provides robust frameworks for modeling these interactions through choreography and orchestration. The choreography focuses on the interactions between different processes, while orchestration defines the flow of activities within a single process; think of it as a dance choreography vs. a music orchestra. 💃🏼🎼
In the context of BPMN, a workflow is a systematic representation of a sequence of tasks, activities, and processes required to complete a specific business objective. "BPMN provides a standardized graphical notation that is easily understandable by all business stakeholders, allowing for the clear documentation, analysis, and optimization of complex business processes. BPMN diagrams can be easily exchanged in a standardized format across different modeling tools" [BPMN].
Workflows are so powerful that many enterprises not only use workflows but also act as providers, offering workflow implementation and system integration services. These companies help other businesses automate their processes by:
Consulting: Analyzing and optimizing existing business processes.
Customization: Developing tailored workflow solutions to meet specific business needs.
Integration: Ensuring seamless integration with existing IT infrastructure and third-party services.
Workflows are not necessarily about automating tasks, but also about implementing business rules. Business rules are logical guidelines that ensure business decisions lead to the right outcomes. This is highly used by non-technical users, like business analysts, to define the rules that the system should follow, for example, a business rule could be as simple as:
"If the customer has a credit score above 700, approve the loan application",
or as complex as:
"If the customer has a credit score above 700, approve the loan application, but if the customer has a credit score below 700, check the customer's income and approve the loan application if the income is above $50,000, or if the customer has no other loans, and the customer has been a customer for more than 2 years and has a good payment history".
Wow, see how complex business rules can be? That's why workflow engines are so powerful, they allow enterprises to define, deploy, and manage business rules and decision logic so that applications can make smart decisions consistently, quickly, and with minimal human intervention.
Based on the complexity of the business rules we can identify the need for a workflow engine that can handle complex, long-running business processes. This is where workflow engines like Camunda, Apache Airflow, Temporal, Zeebe, and Activiti come into play. These workflow engines provide a scalable, reliable, and flexible platform for orchestrating complex business processes and automating routine tasks.
I see you are intrigued by the power of workflows, but why are they so popular in sectors like banking and e-commerce? I think we should explore that next.
The Popularity of Workflows in Banking, eCommerce and Beyond
Workflows are gaining popularity in sectors like Banking and e-commerce due to their ability to automate routine tasks, leading to increased efficiency and improved customer experiences. They eliminate silos, making processes easier and more efficient for project owners, stakeholders, and customers. Banks are increasingly investing in technologies with standards-based modeling for collaboration between business and IT users to ensure that business processes are well understood and easily optimized and automated [Banking].
Why Workflows are Popular in Banking and eCommerce?

Implementing Business Rules with Workflows
Enterprises leverage workflows to define and enforce business rules consistently across their operations. Business rules are logical guidelines that ensure business decisions lead to the right outcomes. Workflow engines allow enterprises to define, deploy, and manage business rules and decision logic so that applications can make smart decisions consistently, quickly, and with minimal human intervention. This is highly used by non-technical users, like business analysts, to define the rules that the system should follow to ensure:
Consistency: Uniform application of business rules across all departments and processes.
Efficiency: Automating repetitive tasks frees up human resources for more strategic activities.
Accuracy: Reduced human error in critical processes like compliance checks, financial transactions, and customer interactions.
System Integrators as Workflow Implementers
Some companies act as providers of workflow implementations and system integrators. They connect the enterprise system with different software systems and platforms from multiple vendors to minimize costs and ensure better efficiency. Enterprise integration allows organizations to seamlessly integrate, unify, and standardize core business capabilities across diverse IT environments.
Roles and Responsibilities of Workflow Implementers
As in the software development lifecycle, workflow implementers have different roles and responsibilities that range from analyzing and optimizing existing business processes to designing scalable and resilient workflow solutions. Here are some of the key roles and responsibilities of workflow implementers:
Designer: Analyze and optimize existing business processes.
Consultant: Provide expert advice on analyzing and optimizing existing business processes
Analyst: Analyze workflow performance and identify areas for improvement.
Auditor: Conduct audits to ensure compliance with regulatory requirements and best practices.
Developer: Develop tailored workflow solutions to meet specific business needs.
Tester: Test workflows to ensure they meet functional and performance requirements.
Integrator: Ensure seamless integration with existing IT infrastructure and third-party services.
Architect: Design scalable and resilient workflow solutions that meet business needs.
Support: Offer ongoing support and maintenance for deployed workflows.
Administrator: Manage user access, permissions, and configurations for deployed workflows.
Trainer: Train users on how to design, deploy, and manage workflows effectively.
Release Manager: Oversee the entire workflow implementation process and ensure successful deployment.
Seems overwhelming, right? Let's group these roles into two main categories: Technical and Non-Technical roles. Technical roles focus on developing, and maintaining workflows, while non-technical roles involve designing, analyzing, optimizing, and managing workflows. This division of roles ensures that workflow implementations are efficient, scalable, and aligned with business objectives.
Additionally, to facilitate collaboration and accountability among workflow implementers, a clear delineation of roles and responsibilities is essential. This is where a RACI matrix comes into play. To create a RACI (Responsible, Accountable, Consulted, Informed) matrix, we'll first group the roles that overlap, and then define their responsibilities. Here are the grouped roles and their new definitions:
Business Process Analyst (BPA): Combines Designer, Consultant, Analyst, and Auditor.
Workflow Developer (WD): Combines Developer and Tester.
System Integrator (SI): Combines Integrator and Architect.
Support Specialist (SS): Combines Support and Administrator.
Trainer (T): Remains as Trainer.
Release Manager (RM): Remains as Release Manager.
Now, we'll create the RACI table for these grouped roles.
RACI Table for Workflow Implementers
| Task / Role | Business Process Analyst (BPA) | Workflow Developer (WD) | System Integrator (SI) | Support Specialist (SS) | Trainer (T) | Release Manager (RM) |
| Analyze and optimize business processes | R | C | I | I | I | A |

Important Features and Components of a Workflow Engine
Features
SRE-M, the acronym for Scalability, Reliability, Extensibility, and Monitoring, represents the key features of a robust workflow engine:
Scalability: Ability to handle growing volumes of tasks and processes.
Reliability: Ensuring high availability and fault tolerance.
Extensibility: Supporting custom task types and dynamic workflow definitions.
Monitoring: Real-time tracking and reporting of workflow execution.
Components
Task Executors: Perform the actual work defined in the tasks.
Orchestrator: Manages the execution flow of tasks.
Persistence Layer: Stores workflow definitions, state, and history.
User Interface: Allows users to design, deploy, and monitor workflows.
APIs: Enable integration with external systems and services.
The goal of great workflow engines is not only to provide an end user's seamless experience, but also an amazing developer experience for defining, executing, and monitoring workflows. This ensures that business processes run smoothly and efficiently.
How to Implement a Workflow Engine in Kubernetes?
Implementing a workflow engine in Kubernetes involves several steps to ensure seamless execution, scalability, and resilience of workflows:
Containerize the Workflow Engine: Package the workflow engine and its dependencies into a container image.
Deploy Using Helm: Utilize Helm charts for deploying the workflow engine, ensuring easy management and scalability.
Define Workflows with CRDs: Use Custom Resource Definitions (CRDs) to define workflows and tasks within the Kubernetes cluster.
Leverage Kubernetes Features: Utilize Kubernetes features like auto-scaling, monitoring, and logging to enhance the workflow engine's capabilities.
Integrate with CI/CD: Implement Continuous Integration and Continuous Deployment (CI/CD) pipelines to automate the deployment and updating of workflows.
Monitor and Optimize: Use Kubernetes-native monitoring tools (e.g., Prometheus, Grafana) to monitor workflow execution and optimize performance.
This process may not be easy, mainly if the engine is not natively designed for Kubernetes (cloud-enabled) and there is a big chance that you will need to write custom code to integrate the workflow engine with Kubernetes. Nevertheless, still, the benefits of implementing a workflow engine in Kubernetes are immense.
If you work with a legacy workflow engine that is not cloud-native, you can still leverage Kubernetes to run your workflows with a "lift-and-shift" approach. This involves containerizing your workflow engine and deploying it on Kubernetes, but they may not take full advantage of Kubernetes' features and capabilities. If you take this approach, you need to commit at the bottom of your heart to migrate to a cloud-native workflow engine in the future, to fully embrace the power of Kubernetes.
