Both LVS and Nginx can be used as multi-host load solutions. They have advantages and disadvantages. in the production environment, you need to analyze the actual situation and make use of it.First of all, I would like to remind you that technology is not a cloud, and my cloud is your cloud. At the same time, we should not be too conservative, too confident in the old method and wait for others to help you with the advance test. It is a good habit to

Server Load balancer has two meanings: first, a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the user's waiting for response time. Second, the operation of a single heavy load is distributed to mul
