What is the server affinity?
When a user logs in to a computer system on the Internet, it can use the basic affinity server technology. This is a technique where the user is tied to a specific computer server on the Internet. This correlation is usually necessary for computer applications that store critical information about the individual. Some examples include online accounts, banking and retail services.
Server affinity is a computer technology where customer information is temporarily stored on a computer device to complete online sales transactions. This is most often used in retail sales programs. Ensures that the transaction remains unaffected on the server until the purchase is completed. This distributed process requires the form of affinity server to ensure that user session activity is available for each request. The load balancer usually manages this professionals in a manner similar to automated traffic shelvesAjt. Once the following request is interpreted, the load balancer determines which server should manage the process.
There are many ways to ensure that the server affinity works. One of the most widely used techniques is known as Sticky Relation Management. This is the process where the user's information information is stored in the local server memory that has started the initial transaction. This information is also stored on a local computer for each additional request as cookies. If the user submits additional requirements, it is automatically focused on the server that has started the transaction.
The server affinity will include several restrictions on a computer application. This technique usually affects performance, flexibility and reliability. When the program uses this approach, it forces applications for switching to specific servers in the cluster. If these servers have become or unavailable, the user usually receives chA YB message that the web site is down, even if other servers are available.
When a distributed computer system is actually balanced, each request is directed to a different server. This load leveling approach is reduced when the technicians of the affinity server are used. The load balancer is forced to send a requirement for specific machines, which can cause the box overload with the requirements.
It is important to consider other options before implementing the affinity server solution. This usually limits the performance and scalability of an Internet application that directly affects the use of the application. Some better options include both local memory storage and database storage techniques that enable the request for a non -community application.
