aws application load balancer

Recently, the company wanted to provide customers with a cluster solution. The project team adopted Apache and tomcat cluster configuration to achieve load balancing. I have never been familiar with Apache before, so I have some hands-on skills. I also searched for many cluster articles on the Internet, but none of them can be configured from start to end, or incomplete files and unclear interpretations. I hope to take this opportunity to share and us

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, w

Load BalancingLoad balancing is our big traffic site to do a thing, let me introduce you to the Nginx server load Balancing configuration method, I hope to have the necessary students help OH.Let's start with a quick look at what is load balancing, which is interpreted literally to explain the average load sharing of n

The main implementation is a high-availability server Load balancer web server cluster, suitable for lamp architecture. The front end uses two servers as The lvs + keepalived load scheduler. N servers can be used as the apache + php application server in the middle, and the next two servers are used as the mysql high-a

1. network load balancing working principle Network Load Balancing uses a cluster of two or more host computers working together to provide high availability and scalability for servers. An Internet client uses an IP address or a group of addresses to access the cluster. Clients cannot distinguish clusters from single servers. Server ApplicationsProgramIt does not indicate that they are running on the clus

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. I have recently learned many articles about Server Load balancer technology on

For example, the network layer LB technology LVS (Linux Virtual Server) front-end proxy (HTTP reverse proxy with Round Robin, database conne
