Currently, F5 type dedicated server Load balancer is the most widely used Server Load balancer device in the data center. You may learn more about Server Load balancer by focusing on DNS technology. The DNS Server
closed for each request. The default listening port is 8007.
3-2 ajp13 type Worker attributes:
When ajp13 type worker is working, the ajpv13 protocol based on TCP/IP socket is forwarded to the Tomcat worker "out-of-process.
The ajpv13 protocol is significantly different from the ajpv12 protocol:
* Ajpv13 has a richer binary protocol. it uses the frequently used string encoding method to compress the request data.
* Ajpv13 reuses opened sockets and retains these opened sockets to handle future r
As a Linux/Unix system engineer, I have been involved in external projects over the past few years. I have worked on the architectures of many small and medium-sized websites. F5, LVS, and nginx have many contacts, I want to explain to you what Server Load balancer is and what is a Linux cluster in a simple and easy-to-understand tone, to help you get out of this misunderstanding and understand them in the
In network applications, "Server Load balancer" is no longer a new topic. From hardware to software, there are also many ways to achieve Server Load balancer. The server Load balancer d
Currently using a hardware load balancer as an Exchange deployment scenario, using a hardware load balancer a good advantage is that the load of the application can be distributed more evenly to the servers in each backend, there are two different modes of operation of the h
Summary: For a large website, Server Load balancer is an eternal topic. With the rapid development of hardware technology, more and more Server Load balancer hardware devices are emerging, such as F5 big-IP, Citrix NetScaler, and radware, however, the high price is often prohibitive, So
initiate the connection, the use of the source address is the SNIP we want to configure , the destination address is the real server IP. From the name subnet IP, you can assign an IP from the device's direct subnet, some of which are similar to the interface IP of some network devices, or the IP of the VLAN.The server's response is also under the same two paragraphs. The server responds to NetScaler SNIP, NetScaler finally uses the VIP response to th
The server Load balancer of the Oracle RAC server distributes new connection requests to the node with the smallest load based on the number of connection loads of each node in the RAC. When the database is running, the PMON process of each node in RAC updates the connection load of each node to service_register every

distribution technology, or the combination of the two. In the IP Server Load balancer technology, the server pool must have the same content to provide the same service. WhenWhen a customer requests arrive, the scheduler selects a server from the server pool based on the server load and the preset scheduling algorithm, forwards the request to the selected serve

Now the trend of Web site development on the use of Network Load balancing with the increase of site size according to different stages to use different technologies:One is the hardware to carry out, the common hardware has more expensive NetScaler, F5, Radware and array and other commercial load
systems or different hardware. For example, a cluster that provides Web Services is a large Web server. However, cluster nodes can also provide services separately.3. Features: based on the existing network structure, Server Load balancer provides a cheap and effective method to expand server bandwidth and increase throughput, enhance
Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load

Now LVS is already part of the Linux standard kernel, Prior to the Linux2.4 kernel, the LVS had to be recompiled to support the LVS function module, but since the Linux2.4 kernel, the various functions of LVS have been built-in, without any patching of the kernel, and the functions provided by LVS can be used dir

LVS is short for Linux Virtual Server. It is a Virtual Server cluster system. LVS operates on the fourth layer of the ISO model because it operates on the fourth layer, therefore, like iptables, it must work in kernel space. Therefore, like iptables, lvs directly wor
