Description

In this comprehensive course, you will dive into the world of design patterns and learn how to leverage them to build highly scalable and resilient reactive microservices using Spring WebFlux. You will explore various Integration Patterns that enable efficient communication between microservices, as well as Resilient Patterns that enhance the robustness of your services. By the end of this course, you will have a solid understanding of how to apply design patterns effectively and create reactive microservices that can handle complex workflows and withstand failures.Course Content:Integration Patterns:Handling multiple reactive microservices communication efficientlyGateway Aggregator Pattern: Reducing network latency and acting as a facade for complex backend servicesScatter Gather Pattern: Routing requests to multiple backend services and aggregating their responsesOrchestrator Pattern (Saga – for parallel workflow): Coordinating multiple backend services in complex workflowsOrchestrator Pattern (Saga – for sequential workflow): Managing sequential workflows by replacing chained microservice callsSplitter Pattern: Processing individual elements in a list of repeating elementsResilient Patterns:Building robust and resilient reactive microservicesTimeout Pattern: Handling unresponsive remote services by setting appropriate timeoutsRetry Pattern: Dealing with intermittent network or remote service issues by retrying failed requestsCircuit Breaker Pattern: Protecting services and meeting SLAs when dependent remote services are unhealthy or unreachableRate Limiter Pattern: Safeguarding services from DDoS attacks and controlling network call limitsBulkhead Pattern: Allocating resources based on priority to prevent one feature’s failure from affecting the entire applicationJoin this course to unlock the power of design patterns and learn how to build scalable, resilient, and highly performant reactive microservices with Spring WebFlux. Gain the skills necessary to tackle complex workflows, optimize communication between microservices, and ensure the robustness of your applications in the face of failures.
