Session retention is one of the most common problems in load balancing and is a relatively complex issue.Session hold is sometimes called sticky session (Sticky Sessions).Before we introduce session-keeping techniques, we have to take some time to figure out the concepts: what is a connection (Connection), what is a se

Nginx upstream currently supports the distribution of load balancing methods 1, RR (default)
Each request is assigned to a different backend server in chronological order, and can be automatically removed if the backend server is down.
For example:

proxy server can monitor backend servers, such as system load, response time, availability, TCP connections, and traffic, so as to adjust the load balancing policy based on the data.

Server Load balancer is a server set composed of multiple servers in a symmetric manner. Each server is equivalent and can provide services independently without the assistance of other servers. Through a load balancing technology, requests sent from outside are evenly distributed to a server in the symmetric structure, and the server receiving the requests indep
we are talking about Load balancer, sometimes called a four-tier load balancer or seven-tier load balancing device, sometimes called a four-layer switch or seven-layer exchange. The four-layer load balancing device mainly analyzes
What is LVS??? Let's start with a brief introduction to LVS (Linux Virtual Server), which is actually a cluster (Cluster) technology that uses IP load balancing technology and content-based request distribution technology. The scheduler has a good throughput rate, transfers the request evenly to the different server execution, and the scheduler automatically shields off the server's failure, thereby forming
