load balance

Elastic Load balancer is an important feature in EC2. It can be used with auto scaling and The multip-Az of RDS to implement a very cost-effective and highly available structure. Let's first look at the most basic ELB structure. ELB uses DNS rotation to distribute data and achieve high availability for user requests. 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M01/44/36/wKioL1PgEBnC017wAABe3K-X22s819.png "style =" float: none; "Title =

use their own web site so that their web site is split up reasonably. * We provide a load-balanced web site, which means that multiple Tomcat workers are used simultaneously, and each tomcat worker has a separate host and assigns requests forwarded over the Web server between workers.

Iptables and iproute2 are used to achieve network load balancing. Assume that there are two external interfaces in the Network: eth0 172.16.1.1/24, eth1 10.0.0.1/24, and the interface connecting to the internal network is eth2 192.168.1.1. Now we have designed such a policy to export all the web service data from the internal network to 172.16.1.1. Other data goes to the exit 10.0.0.1. # Set ifconfig eth0 172.16.1.1 netmask 255.255.255.0ifconfig eth1

The two-fork search tree is described earlier, and he has no problem with the efficiency of finding and inserting in most cases, but he is less efficient in the worst case. The data structure of the balanced lookup tree introduced in this article and later in this article ensures that the LGN efficiency can be achieved in the worst case, and we need to make sure that the tree remains in equilibrium after the insert is complete, which is the Balanced search tree. In a tree with n nodes, we want t

First of all to understand what is the white balance, it refers to the process of image processing, the original material is a white object of the image color reduction, the effect of removing the external light color temperature, so that it is also shown in the photo white.How does the color temperature understand?

If T is a non-empty Binary Tree, its left and right subtree are TL and TR, make HL and HR respectively the depth of left and right subtree. When and only when① TL and TR are balanced binary trees;② | HL-HR | ≤ 1;T is a balanced binary tree.(Example) 8.4.(A) balanced binary tree (B) non-balanced binary treeFigure 8.3 balanced binary tree and non-balanced binary tre
