Introduction to economy instances and standard instances
Economy instances allow you to use higher instance specifications at lower costs. This type of instance is provided based on intelligent cost management and resource integration. Economy instances provide high stability and availability, help reduce IT costs, and are suitable for enterprises that require cost reduction and efficiency enhancement.
