  Principles Used to Design Microservice Architecture The principles used to design Microservices are as follows: Independent & Autonomous Services Scalability Decentralization Resilient Services Real-Time Load Balancing Availability Continuous delivery through DevOps Integration Seamless API Integration and Continuous Monitoring Isolation from Failures Auto -Provisioning Design Patterns of Microservices Aggregator API Gateway Chained or Chain of Responsibility Asynchronous Messaging Database or Shared Data Event Sourcing Branch Command Query Responsibility Segregator Circuit Breaker Decomposition API Gateway Design Pattern Microservices are built in such a way that each service has its own functionality. But, when an application is broken down into small autonomous services, then there could be few problems that a developer might face. The problems could be as follows: How can I request information from multiple microservices? Different UI require different data to respond to ...
