E-commerce Web site technology architecture with over 1 million visits The first introduction to E-commerce Web site high-performance, highly available solutions. From the frame composition of the scheme, the application is lvs+keepalived load balance. Achieve high-performance, highly available solutions (server clusters, load Balancing, high-performance, highly available, highly scalable server cluster)

Use Network address translation to achieve multi-server load balancing. Abstract: This article discusses the server load balancer technology and load allocation strategies used by distributed network servers, and implements the server load

Today, the ' large server ' model has been replaced by a large number of small servers, using a variety of load balancing techniques. This is a more feasible approach that minimizes the cost of hardware. The advantages of ' more small servers ' outweigh the past ' large server ' patterns in two ways: 1. If the server goes down, the load balancing system will stop requesting the server to go down and distrib

I. Concepts of reverse proxy and Server Load balancer Before understanding the concepts of reverse proxy and Server Load balancer, we must first understand the concept of a cluster. Simply put, a cluster is a server that does the same thing, such as a web cluster, database cluster, and storage cluster, the cluster has

network data processing capabilities, and improve network flexibility and availability. Server Load balancer has two meanings: first, a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the user's waiting for response time. Second, the operation of a single heavy load is distributed to mul

Server Load balancer is a technology that implements Load Balancing through an algorithm. In layman's terms, requests are uniformly distributed to devices,Server Load balancer will receive all requests in a unified manner, and then distribute these requests to the server

log cannot be written to the problem that eventually causes the entire application to crash.3. Logging to logging server you can use a logging software, such as a syslog, to write all the logs to a central server. Although this method requires more configuration, he also provides the most robust solution. PHP Load Balancer Instance If you want to use load balanc

systems. Distributed and business splitting solves the problem from centralization to distribution. However, each deployed independent business still has single point of failure and unified access portal. to solve single point of failure, we can adopt redundancy. Deploy the same application on multiple machines. To solve the unified access problem, we can add a server load balancer device in front of the c

Ribbon Load BalancingThe above code shows that there is a load-balanced annotation in the Ribbon: @LoadBalanced, it means that

Origin:Because I plan to develop a server similar to instant messaging, I need to plan the framework for future development. The most important solution is to connect the client to the server. As the number of customers increases (for example, 1 million), online and offline (for example, 10 thousand) at the same time will put a lot of pressure on the system. In addition, Server Load balancer should be consi
