oversize load routing software

"Reading notes" to understand service routing and load Balancing, micro-services to get up 1 Basic Concepts Soa The public business is split up to form a shared service that maximizes the reuse of code and logic and avoids duplication of construction, a design called an SOA. Routing In the SOA architecture, service Consumers find the address list of services to

With the development of China's routing industry, it also promotes the development of its related products, especially the market demand for software routing firewalls is gradually increasing. I believe that the routing technology will also be improved, it provides users with a better network environment. I. Descriptio

First, the LVS introduction LVS is the abbreviation of Linux virtual server, that is, the Linux virtualized servers, is a free software project initiated by Dr. Zhangwensong, its official site is www.linuxvirtualserver.org. 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, wi

IP Load Balancing TechnologyLoad balancing technology has a number of implementation scenarios, there are methods based on DNS domain name rotation, there is a method based on client scheduling, there are scheduling methods based o

. Instead of executing the LVS script we configured above, because Ldirectord will automatically call Ipvsadm to create the LVS routing table, we have described above using the IPVSADM command line to configure LVS in order to give readers a deeper understanding of IPVSADM implementation details and implementation mechanisms.If you are configuring LVS through the Piranha tool, you do not need to use the Ldirectord,piranha tool for the system process i

Three major software load balancer comparisons (LVS, Nginx, HAproxy)(Information from the network, made part of the supplementary instructions)LVS:1. Strong anti-load capability, high performance, can reach F5 60%, low memory and CPU resource consumption2. Work in the Network 4 layer, through the VRRP protocol (for Proxy only), the specific traffic is handled by

If you restart the real Server1 service, Ldirectord will be able to automa

A brief introduction of LVS LVS is the short name of Linux virtual server, the Linux VM, a free software project initiated by Dr. Zhangwensong, and its official site is www.linuxvirtualserver.org. Now that LVS is already part of the Linux standard kernel, Before the Linux2.4 kernel, the use of LVS must be recompiled to support the LVS function module, but from the Linux2.4 kernel, has been completely built in the LVS function modules, no need to make

Someone in the mailing list asked Haproxy why the haproxy, whether TCP or HTTP, is not too large to support the amount of concurrency.Willy answered the question.Exactly. The difference is between LBs Process a stream and whichis proxy-based, and the ones which process packets and is basicallyRouters . In order to parse and modify a stream, you need some memory,While you don ' t need this to route packets (beyond the routing queue).L4
