There are many ways to load balance the web, and here are a few common load-balancing methods. 1. User manual Selection method This is an older way. Load balancing is achieved by providing different lines and different server conn
database: Can reduce the load of a single machine, while minimizing the loss caused by downtime;
Load balancing strategy: can reduce the access load of a single machine, reduce the possibility of downtime;
Cluster Solution: Solves the problem that the single point database can not be accessed by the database o
are many things to do. The Nat mode is simple, that is, to change the IP address and port information to the IP address and port of the real balancing machines, so that the real service machines are hidden behind the Load balancer, the idea is the same as that of normal Nat.[Tunnel mode]: The tunnel mode is to repackage data into a new IP data packet, and then send the data to the virtual Nic by modifying
LVS Load BalancingRecently in the study server load Balancing, read some information on the Internet, found that the main software load Balancing scheme has nginx (load
The pros and cons of load balancing strategies and their ease of implementation have two key factors:(1) Load Balancing algorithm(2) The detection mode and ability of network system condition1. round robin (Round Robin): Every request from the network is assigned to an internal s

Load Balancing among multiple applications is a commonly used technology to improve resource utilization, increase server throughput, reduce latency, and ensure application fault tolerance. Nginx can serve as an efficient HTTP
Load BalancingLet's start with a quick look at what is load balancing, which is interpreted literally to explain the average load sharing of n servers, not because a server is under-loaded and idle on a single server. Then the pre
The commercial license version of Nginx Plus is beginning to feature TCP load balancing. Starting with Nginx version 1.7.7, it is now a commercial fee version that you want to try and apply on the website. In other words, nginx in addition to the usual HTTP load balancing, Nginx increases the implementation of TCP prot
In general, load balancing is the client's request to the backend of the various real servers to achieve load balancing purposes. There is another way is to use two servers, one as the primary server (master), the other as a hot Standby, the request is all to the primary
Session retention is one of the most common problems in load balancing and is a relatively complex issue.Session hold is sometimes called sticky session (Sticky Sessions).Before we introduce session-keeping techniques, we have to take some time to figure out the concepts: what is a connection (Connection), what is a session, and the difference between the two. In particular, if we are just talking about
Load Balancing with HaproxyFirst, the conceptHaproxy is a free and open source software written in the C language [1] that provides high availability, load balancing, and application proxies based on TCP and HTTP.Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven
BGP routing load balancing fault caseNetwork Architecture 1. Topology: the actual network structure is simplified considering the privacy of the company's network and a clearer description of fault phenomena. 2. network planning and data Configuration Overview: ◆ ASR9K establishes IBGP neighbor relationships with two n7ks Based on the interconnected addresses respectively; ◆ ASR9K is connected to the
I. The concept of LVS
LVS (Linux Vsan): Linux virtual server;
LVS is a load balancing device. It does not provide whatever service. When the user requests to be here. It is the service that forwards the customer's needs to the backend to truly deliver the service. So, the backend service is called real server
(Network File System) sharing services.
The typical topology of the Server Load balancer cluster is as follows:
3. Load Balancing Mode
The Cluster load scheduling technology can be distributed based on IP addresses, ports, and content. The IP-based
It is best to divide the routing load balancing network segments. This will not disrupt the routing behavior at the network layer, because the host or router forwards each packet through the "Route" found in the route table, unless the load balancing of the route table is achieved, otherwise, only a unique route is sel
A mention of load balancing, I believe many students will directly think of nginx reverse proxy, because we are usually more familiar with Nginx to do Web services load balancing. In fact, Nginx is only part of the load balancer, and each level in the Web application actuall
In some cases, the expansion is obvious, such as the download service due to insufficient bandwidth and must be extended, but, other times, many people see the site performance is not satisfactory, immediately implement load balancing and other expansion means, really need to do this? Of course, the problem is only their own to answer, in addition to high availability and deployment considerations, in most
