First, what is the elastic expansion of elastic expansion was originally proposed by the Amazon concept, elastic expansion is a dynamic expansion of the cloud application itself, during the operation of cloud applications to achieve support cloud application of the virtual machine instance number of dynamic increase or decrease, popular point is in high load time to start more instances, A low load situation stops some instances. Elastic expansion for cloud applications achieves a real sense of resource demand. Elastic expansion is not simply a figment of the imagination, for application services, increasing the number of servers is only to increase the capital ...
