global load balancing dns

Load Balancing (Balance) is one of the factors that must be considered in the design of distributed system architecture.It usually means to allocate the request/data "evenly" to multiple operation units, and the key of load balancing is "uniformity". The uniformity here is not the 10÷2 = 5 we imagined, which is even. N

Four common methods for server load balancing in enterprisesIn order to improve the performance and workload of the server, enterprises usually use the technology of DNS server, network address translation and so on to realize multi-server load balancing, especially the Inte

device in front of the cluster to achieve traffic distribution.Load Balancing (Balance), which means that load (work tasks, access requests) are balanced and distributed across multiple operating units (servers, components) for execution. is the ultimate solution for high-performance, single-point-of-failure (high availability), scalability (horizontal scaling).This article is the first article on

The accuracy and efficiency of load balancing directly determines the efficiency and performance of the entire CDN website Acceleration Service. CDN Load Balancing Technology distributes network traffic as evenly as possible to several servers or

server in the cluster, record the current number of connections per server, and the load balancing system always selects the server assignment tasks with the fewest number of current connections. This is much better than the "round robin algorithm" because, in some situations, simple rotations cannot tell which node is less loaded, and perhaps the new job is assigned to a server that is already busy.The ③

subsequent operations are based on the new URL (that is, the back-end server), after which the browser does not have a relationship with the dispatch server, resulting in several problems: Because of the different user's access time, the access page depth is different, thus each user to the respective back-end server caused the pressure also different. The dispatch server in the scheduling, can not know how much the current user will put pressure on the server, so this way can not achi
