Shenzhen Polytechnic College of Electronics and Communication EngineeringStorage Cloud Service – Elastic Volume Service TargetAfter completing this course, you will be able to:Describe Huawei EVS service.Master the concept, function and application scenario of EVS. EVS ConceptElastic Volume Service (EVS) is a kind of virtual block storage device based on distributed architecture, which can be elastically extended. EVS can be regarded as cloud disk service.You can create a Elastic Volume Service (EVS) online and attach to the cloud server. The use of the Elastic Volume Service (EVS) is exactly the same as the traditional server hard disk.Elastic Volume Service (EVS) is a kind of virtual block storage device based on distributed architecture, which can be elastically extended. You can create a Elastic Volume Service (EVS) online and attach to the cloud server. The use of the Elastic Volume Service (EVS) is exactly the same as the traditional server hard disk. At the same time, Elastic Volume Service (EVS) has the characteristics of higher data reliability, higher I / O throughput and easier to use. It is suitable for file system, database or other system software or applications that need block storage devices. EVS Product StructureEVSEVSBackup and create new hard diskMonitor the input-output rate and input-output operation rate of EVSECSEVS backupCloud monitoringBackup recovery to EVSCreate backupUsers can attach the EVS on the elastic cloud server, and the EVS supports capacity expansion.The EVS backup service enables backup and recovery of the EVS, and supports the creation of a new EVS through the EVS backup to improve the data reliability.Monitor the input-output rate and input-output operation rate of the EVS through the cloud monitoring service.
