iis load balancing

Recently in the learning database of read-write separation and master-slave replication, the use of a master multi-slave strategy, using polling method, read the contents from the database. However, if a certain station from the database down, and the client does not know, each round to choose this from the database, do not have to error? Online access to the information, found a good blog post, not only the solution, but also detailed about the database partition, sub-table, cluster and

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 server, when the primary server, immediately swi

Objective: With the explosive growth of Internet information, load balancing (loading balance) is no longer a very unfamiliar topic, as the name implies, load balance is to spread the load to different service units, not only to ensure the availability of services, but also to ensure that the response fast enough to g

encryption in ASP is dependent on the value inside the machinekey, such as the Forms authentication Cookie, ViewState encryption. By default, The configuration of the ASP is self-generated, if a single server is certainly not a problem, but if more than one server load balancing, machinekey also adopt dynamic generation, each server machinekey value inconsistent, resulting in encryption results are not con

Good blog is generally able to do "look at the title of the text," to see the next heading to know what to say below, to write this title hesitated, would have to be the title of the Apache+tomcat to achieve load balance, but also think it seems more fuzzy. After thinking about it, I think that using Apache to do load balancing the bottom of the combination is th

1. Load Sharing-solutions for large service nodesA large amount of access traffic and users are the goal of information service providers. However, a large amount of access will impose a heavy burden on servers. As the number of users of excellent Internet application services increases, the server becomes overloaded. If a large number of user service requests cannot be processed in a timely manner, service interruption may occur. In the past, when so

The main task of the general balancing algorithm is to decide how t

Web cluster selection and implementation of load Balancing scheme for service The Web application server cluster system is a cluster system composed of a group of servers running the same Web application at the same time, which looks like a server to the outside world. In order to balance the load of cluster server and to optimize the performance of the system

Nginx reverse proxy for load Balancing configuration diagram[Introduction] Load Balancing configuration is a very large machine needs to consider some of the problems, but also a data security approach, let me introduce the reverse proxy load Balancer configuration diagram i

DNS load balancing method The RR-DNS (round-robin Domain Name System) takes turns by: In a DNS server,You can configure the same name for multiple IP addresses. When the client queries this name, it will get an address when parsing this name. Therefore, for the same name, different clients will get differentTo achieve

Load Balancing cluster (LB)How load Balancing clusters workWhen a user sends a request, the request is not immediately sent to the backend's real server (realservers), but is sent first to the Scheduler or Distributor (Director), and then the director, based on some scheduling algorithm, The request is sent to the back

. Apache can have a good static page processing capabilities, if paired with Tomcat can support both static and dynamic pages 2. Tomcat can assume low performance requirements for Web applications. Load Balancing In order to improve the usability and performance of the whole system, load balancing is often used, while

, and use the default value set for dfs. replication in the hdfs-site.xml if not specified in the startup command; HDFS Load Balancing HDFS clusters of Hadoop are prone to unbalanced disk utilization between machines. For example, when a node is added or deleted in a cluster, or the hard disk storage of a node is saturated. When the data is not balanced, the Map task may be assigned to a machine that does n

1. Overview The interaction between the DHCP Client and the DHCP Server involves both broadcast packets and unicast packets (used during renewal, we know that the general Server Load balancer equipment implements Load Balancing for unicast packet data, so the pure DHCP Client-> DHCP Server architecture basically cannot achieve

Overview Load Balancing is built on the existing network structure, it provides a cheap, effective, and transparent method to expand the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and improve network flexibility and availability.Prerequisites You have installed Apache and can run it. The system used in this article is: centos6.2, Apache: Apac

The use of Network Load Balancing technology enables the availability and scalability of some applications: IIS, firewalls, VPNs, and some key businesses. Each node runs a copy of the application. NLB distributes incoming client requests in multiple hosts in the cluster. You can dynamically add a host, or you can boot all traffic to a specific single host, which
