HAProxy for Server Load balancer HAProxy provides high availability, Server Load balancer, and TCP and HTTP application-based proxy. It supports Virtual Hosts and is a free, fast, and reliable solution. HAProxy is especially suitable for websites with extremely high loads, which usually require session persistence or layer-7 processing.

HAProxy is a free, fast, and reliable proxy solution that supports high availability and server load balancer. It is also suitable for proxies for TCP and HTTP-based applications. For some websites with high load, HAProxy is particularly suitable. HAProxy supports tens of thousands of concurrent connections. It is easy to configure and can easily integrate into o

Reverse proxy Server features: Web caching (acceleration), reverse proxy, content routing (forwarding requests to a specific server based on traffic and content type, etc.), transcodingCache: Reduce redundant content transmission, save bandwidth, alleviate network bottleneck, reduce the request pressure on the original server, reduce the transmission delay, public cache everyone can use, private cache with sensitive data only for the qualification of a class or a person to useNginx can implement

Haproxy compared to the use of LVS is much simpler, functional aspects are also very rich. Currently, Haproxy supports two main proxy modes: "TCP" is also 4 layers (mostly for mail servers, internal protocol communications Servers, etc.), and 7 tiers (HTTP). In 4-tier mode, Haproxy only forwards bidirectional traffic between the client and the server. In 7-tier m

Overview:Haproxy is a cluster scheduling tool that provides high availability, load balancing, and proxy software based on TCP (layer fourth) and HTTP (layer seventh) applications, supporting virtual hosting, which is a free, fast, and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. Haproxy runs on today's hardwa

When you use load balancing, you will experience session retention problems, which are commonly used in the following ways:1.IP Hash, assigning requests to different servers based on the IP of the client2.cookie, the server sends a cookie to the client, and a request with a specific cookie is assigned to its publisherNote: Cookies require browser support and sometimes reveal data 1.Sticky Working principle:Sticky is a nginx module that is a nginx load

Haproxy implements fully transparent Exchange proxy service I. background The company recently used the Exchange mail system to build a highly available mail system architecture. Front-End Server Load balancer uses Microsoft's NLB to achieve cas load balancing. However, some problems have also been found in the solution implementation project. using NLB to generate a large number of broadcast reports in the network causes serious packet loss problems.

In the Internet era, the backend system architecture, often can hear the high-availability cluster, load-balanced cluster and other system architecture solutions, including load balancing hardware-based F5, big-IP, and software-based LVS (based on the Linux operating system implementation, performance and hardware-based performance comparable), Nginx, HAProxy (based on third-party application implementation) and so on, this article describes the insta

In comparison, LVS performance is the best, but the construction of relatively complex, Nginx upstream module support cluster function, but the cluster node health Check function is not strong, performance is not haproxy good.

In the production environment, the MongoDB shards are built, providing three mongos interfaces. However, there is no failover mechanism in MongoDB, the official recommendation is to deploy MONGOs and application servers together, multiple application servers will deploy multiple MONGOs instances, which is inconvenient. Check it out, there are several ways to make these three mongos interfaces available, reducing the pressure on a single interface. Commonly used are LVS and
