akamai application load balancer

Based on the huge network structure, the use of Cluster Server brings a lot of load problems such as traffic. So the relative, load-balanced technology also emerged. Each technology requires product support, so let's now look at one of the F5 load balancers. So first of all, we first introduce the structure of the product function.Many vendors have launched a

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

}After the modification, also modify the server listening port, the original content is as follows:server {Listen 80;server_name localhost;......The following changes are completed:server {Listen 8086;server_name 10.0.2.136;......In this way, Nginx starts listening for the local IP (10.0.2.136) 8086 port request after booting, then turns its request to the two IIS sites specified in mylocalsite and forwards the results to the client. If everything is configured correctly, then you can run C:/ngi

Whether or not the developed website can withstand this pressure and how to ensure that the load of the website is no problem, after research, it is decided as follows: (1) Server Load balancer and cluster t

Cluster technology is a very popular method to improve the system service capability and high reliability (Ha-high availability). By combining multiple independent servers into one cluster, failure can be seamlessly transferred. That is to say, when a server in a cluster becomes a machine, the user status data on it can be seamlessly migrated to other servers in the cluster. In this way, the customers who are using the application can completely feel

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.
