This is something for DevOps but as a developer we should also be familiar with this. As per this principle, the deployment and management of microservices should be automated, to ensure consistency and efficiency.

For example, you can use tools like Docker or Kubernetes to automate deployment and scaling of Microservices. This is actually the standard practice now across the firms and it ensure that the deployment process is consistent and efficient.

You can create Jenkins pipelines for automatic deployment and you can also use tools like Terraform to create environment automatically. Here is an example pipelines for automatic deployment of Microservices.

That’s all about the essential Microservices design principles every Java developer should know. By following these design principles, you can build scalable and reliable micro services applications that can meet the demands of their customers.

They will not only help you to build robust and scalable Microservices but also save time while debugging, monitoring, troubleshooting, and maintaining Microservices, which is a major challenge in the ever growing space of Microservices.
