Performance Performance is an indication of the responsiveness of a system to execute any task within a given time interval. In simple words, how quickly a resource can be accessed by another resource or user in a given time.It can be measured in terms of latency or throughput. Latency is the time taken to respond to any event. Throughput is the number of events that take place within a given amount of time. Common causes:Unnecessary round-trip to serverProblem in defining the boundary of Microservices which results in ChattinessNo or minimal asynchronous communication.No caching.No load balancing.Unnecessary data sent over the network.Database or software design issues. Points to be considered: Reduce the unnecessary round-trip to the server.Define efficient and appropriate caching strategy.Use efficient queries to minimize performance impact, and avoid fetching all of the data when only a portion is displayed. Try to reduce the number of transitions across boundaries, and minimize the amount of data sent over the network.Async communication instead of sync communication.Performance Monitoring.Scale Up or Scale OutEvent based communication Common Patterns:Cache-Aside Pattern Choreography over OrchestrationCQRSEvent SourcingMaterialized ViewPriority QueueQueue-Based Load LevelingSharding Static Content Hosting Throttling
