different technologies:The first stage: using Nginx or Haproxy for a single point of load balancing, this stage of the server scale just out of the single-server, single-database mode, requires a certain load balancing, but still small, no professional maintenance team to maintain, there is no need for large-scale sit

layering principle, a new IP header mark (incomplete IP header, only the destination IP address) is sent to the REALSERVER. After receiving the data packet, the REALSERVER unlocks the header of the data packet sent by the DR device, restores the original data packet, and then directly returns the data packet to the client, you do not need to go through DR. It is worth noting that because REALSERVER needs to restore the data packets sent by DR, that is, it must support the IPTUNNEL protocol. The

It is also said that each server has two IPs.Yes, each computer can have multiple IP addresses.Advanced options, you can add multiple IP addresses manually.Open Network Load Balancing Manager, new clusterAlways point to "next" until finished.The 192.168.99.10,192.168.99.20 servers are operated separately.Always point t

, and use dns for dynamic resolution. For ultra-large websites, you can use Squid, nginx for medium to large sizes, and varnish for internal use.3. Balance the front-end. If you have enough funds, you can use up to 100,001 hardware devices. If you already have a technical team, use nginx/haproxy + keepalived to build your own front-end. Balanced methods are flexible, with random, weight, ip, and url options.4. Synchronization depends on what to synchr

upper limit, and there is basically no consumption in memory and CPU. 2. Low configuration, which is usually a major disadvantage, but it is also a major advantage. because there are not many configurable options, you do not need to touch the server frequently except increase or decrease the server, this greatly reduces the likelihood of human error. 3. Work is stable. Because of its strong load resistance

processed by a single server. However, if a single physical load balancer or a single network switch is used in front of a set of software load Balancing servers, another point of failure will be introduced. You can reduce this risk by using redundant load balancing devices

to use the domain service, you typically add the Active Directory Domain Services role and forest, domain configuration before installing the Network Load Balancing Manager. If the server needs to use IIS or asp.net, it is recommended that you add the Web server (IIS) server role and the. NET Framework 3.5 features before installing NLB 5.2. To establish a Network

very good to solve, as long as the DNS server to enable the "Enable netmask sorting" feature. In the DNS Manager window, right-click on the DNS server, select "Properties" in the pop-up menu, then switch to the "Advanced" tab in the Properties dialog box, and tick the "Enable netmask sorting" option in the "Server Options" list box. This allows the client to access the Web server in the subnet every time. After completing the above setup, the DNS ser

The difference between four and seven layers of load balancing four layersThe so-called four layer is the fourth layer in the ISO reference model. Four-layer load balancing is also called four-layer switch, it is mainly through the analysis of IP layer and TCP/UDP layer of traffic implementation based on IP plus port

rich set of features for DNS integration that has become increasingly popular. Other popular options are the use of distributed and replicable Key-value storage, such as ETCD in which services can register themselves. Apache Zookeeper will also be aware of the need for such a group of people. In this article, we mainly deal with some of the mechanisms provided by Docker swarm (Docker in swarm mode) and demonstrate the service abstraction we explored
