Orchestrate Microservices

Camunda provides orchestration that enhances the autonomy of microservices.

Integration Without Compromising Loose Coupling

Microservices architectures have become increasingly popular for their flexibility and agility. However, it’s important to keep in mind that an end-to-end, automated business process typically requires multiple microservices to achieve an outcome. Software developers and architects often struggle to effectively communicate across multiple microservices, monitor their performance, and identify and resolve problems when they occur.

Camunda enables organizations to overcome these issues without compromising the paradigms of autonomy and loose coupling of microservices. Plus, Camunda offers speed, scale, security, and resiliency for microservices, without the overhead of building and maintaining infrastructure.

The Challenges of Microservices Architectures:

Visualizing end-to-end processes across microservices

Communication across multiple microservices

Event monitoring and troubleshooting

Maintaining state while resolving issues during disruptions

Development inconsistencies across software teams

End-to-End Service Orchestration Lifecycle

Design

  • Visual processes modeled in ISO-standard BPMN, allowing business and IT stakeholders to collaborate on process design in a common language
  • Dedicated orchestration logic making it easy to implement changes
  • Build a catalog of reusable templates for common scenarios to enable faster orchestration

Automate

  • Highly scalable execution engine to natively automate and execute BPMN models without violating core microservices paradigms such as isolation of services
  • Monitor processes with the ability to discover and analyze technical service issues
  • Maintain process state in case of service disruption, allowing the process to resume when the service is available again

Improve

  • Compare process logs with BPMN diagrams to identify potential issues in service execution
  • Use BPMN heatmaps to identify ways to improve efficiency
  • Customizable reports and dashboards on process performance and business KPIs for decision makers

Decoding Microservices: Best Practices Handbook for Developers

Microservices architectures feature an unavoidable tension in how they function. On one hand, they require services to be as loosely coupled as possible. At the same time, these services must be able to communicate effectively to execute the business processes at the proper time and in the correct way. Check out Decoding Microservices: Best Practices Handbook for Developers to learn how to avoid this issue and many of the other challenges through following some best practices.

Benefits of Camunda’s Workflow Engine For Microservices

State Handling:
Persists the state of each instance of a business process (e.g., each order placed on an ecommerce website)
Explicit Processes:
Makes business processes explicit instead of burying them in code, making it easier for teams to understand and modify them
Message Correlation and Coordination:
Merges messages belonging to a single process instance and decides next steps — BPMN automatically implements message patterns such as sequences, synchronization, mutual exclusion, and timeouts
Compensation for Problems:

Compensates if a business transaction or process encounters a problem that requires previously completed steps to be undone

Timeout Handling:

Tracks the passage of time and automatically takes action or switches to another path in the process flow if an event does not take place as expected

Error Handling:
Allows you to specify the behavior that should happen when an error occurs (e.g., retrying an action, taking another path)
Transparency of Status:
Enables operations teams to monitor the status of process instances in real time
Collaboration:
Provides graphical models of business processes that facilitate discussion between business stakeholders, developers, and operations teams

“We see Camunda as a valuable component within our new lending platform, which is built using a microservices architecture. To achieve the desired efficiency gains, we needed a much higher degree of automation in our processes, and Camunda’s capabilities fits our needs well. It is modern, easy to integrate with, and gives us flexibility when designing our processes.”

“As a part of our investment in the next generation of microservices-based banking applications, we were looking for embeddable workflow engine. After detailed examination and a proof-of-concept project, we decided to use Camunda for its excellent support for BPMN and DMN standards; its lightweight engine; and the agile evolution of a codebase that follows market needs.”

Swiss Re – A Transformative Journey Toward a Modern and Cloud-Native Orchestration Solution

Many organizations want to migrate to a next-generation, cloud-native process automation platform. Such a migration can be a complex, painful, and expensive business – even if done right. This session from CamundaCon 2021 explains how to successfully modernize process automation, with lessons learned along the way.
