First, we need to take advantage of cloud computing - Elastic
Cloud computing is a major advantage is that you can always adjust the cloud server configuration, many users in the cloud will have on this consideration, I need now is not a cloud server configuration and bandwidth high, behind the upgrade simple? The high cost of it? In fact, we buy when Ali cloud server, if the premise is not very high bandwidth requirements and configuration, can buy low with the first, the late business needs and bandwidth can be flexibly adjusted according to the configuration, I encountered a lot of users, pre buy cloud server bandwidth only 1-2M, in the business of advertising or doing activities when the cloud server traffic will be explosive growth, this time, the user will select a temporary increase bandwidth, after the traffic down, and then reduce the bandwidth to ensure that the daily flow requirements can be.
