. Request Routing decisions made based on HTTP requests Unlike Hardware load balancing (the Request Routing Method is determined at the OSI model's IP layer), ARR performs Load Balancing Based on the application layer, because more information is available at the application layer (in fact, it is necessary to clarify the principle of Server

load balancing is mainly through the server node to install the device specifically for load balancing, such as F5, and software load balancing is to complete the request distribution work by installing some software with load balancing function or module on the server, suc

When it comes to the Web cluster, we can't help but say that LVs is a very good open source software for load cluster, compared with some hardware load, LVS has many excellent performance, such as cheap, stable, support high concurrency scenarios in most cases, below to tell you about the origin of LVS and basic introductionI. The concept of LVSLVS is the abbrevi

, its processing capability and computing strength also increase accordingly, making it impossible for a single server device. In this case, if you discard the existing device to perform a large number of hardware upgrades, this will cause a waste of existing resources, and if you face the next increase in business volume, this will lead to a high cost investment for another hardware upgrade, and even devic

group, which is the node of each library we introduce multiple machines, each of which holds the same data, and in general the load is distributed by multiple machines, and the load balancer distributes the load to the machine that is down when there is an outage. This solves the problem of fault tolerance.As shown, t

We introduce the concept of clustering , which I call group, that is, each node of the library we introduce multiple machines, each machine holds the same data, in general, many of these machines load, when there is a downtime situation, The load balancer allocates the

I used nginx to implement the website load balancing test. In windows, IIS performs load measurement. If your website traffic (pv) is getting higher and higher, and one server is no longer able to withstand the traffic pressure, increase the number of WEB servers for load. Website load can be achieved by buying

with our solution, and fault-tolerant performance is not a test. Of course, there is always a solution to the problem. We introduce the concept of clustering, which I call the Group, which is the node of each library we introduce multiple machines, each of which holds the same data, and in general the load is distributed by multiple machines, and the load balancer
