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
Today, the 'large Server' model has passed, replacing it with a large number of small servers, using a variety of load balancing technologies. This is a more feasible way to minimize hardware costs.
The 'more servers' mode has more advantages than the 'large Server' mode in the past. It is reflected in two aspects:
1. If the server goes down, the Server Load balan
[Oracle] RAC-Server Load balancer distributes loads evenly to each node in the cluster to improve overall performance. Oracle RAC provides two methods to achieve load balancing. The first is pure technical means, that is, when a user connects, the node that determines based on the current load of the system to process

F5 is a well-known Server Load balancer product. I believe many people will not know it. So how does it maintain sessions? Let's start with the definition of session persistence. As an image metaphor: Session persistence can be seen as a string of pearls, so we split each Pearl and put it in a different box for storage and then put it into a string, that is, the concept of allocation. So how do we describe
