Research on Distributed Storage and load balancing of Massive images
For Web servers, users' access to image information consumes a lot of server resources. When a Web page is browsed, the Web server establishes a connection with the browser. Each connection represents a
Network | site
Many network protocols support the "Reset to" feature, such as supporting the location instruction in the HTTP protocol, and the browser receiving the instruction will automatically reset to another URL specified by location. By sending location instructions, the Web server is much less loaded than executing service requests, so you can design a load-balanced server based on this feature. At any time, when the Web server thinks its

1. OverviewThe first two times in this article, we have been talking about the construction of Nginx + keepalived. At the beginning of this article, we are going to honor the promise of the previous article, the following two articles we will introduce the Nginx + keepalived and LVS + keepalived to build a highly available load layer system. If you do not know about Nginx and LVS, see my previous two articles, "Architecture Design:
LB (load balance) Load Balancer clusterPrinciple: When a user's request comes in, it is sent directly to the dispatcher (Director server), which then distributes the user's request intelligently and evenly to the backend really server (real server) according to the pre-set algorithm. If different machines may request data differently, in order to avoid this situation, use shared storage to ensure that all u
PHP Simple calculation of page load time method, PHP calculation page load
This article describes a simple way to calculate page load time in PHP. Share to everyone for your reference. The implementation method is as follows:
Simply put the start time on the page header, end time on the tail of the page, calculate the page
Nginx + IIS implements Load Balancing Session multi-site sharing and nginx Load Balancing
The days have been too boring. I studied the so-called load balancing (mainly under windows Server IIS ). Let's take a look at the analysis diagram:Environment:Linux Server: centos 6.3Windows server: windows server 2012 IIS 8.5Database: SQL Server 2008 R2I deployed nginx on

The following describes how to use js to load FusionCharts graphics in five steps.
Step 1: import the FusionCharts. js File
Step 2: Define a DIV, which must have an element: id
Step 3: Create a FusionCharts object

Five Policies for configuring Server Load balancer using nginx in the production environment: nginx Server Load balancer
Nginx upstream currently supports five allocation methods1. Round Robin (default)
Each request is distributed to different backend servers one by one in chronological order. If the backend servers are down, they can be removed automatically.
2. weightSpecify the round-robin probability. w

Both LVS and nginx can be used as multi-host load solutions. They have advantages and disadvantages. in the production environment, you need to analyze the actual situation and make use of it.
First of all, I would like to remind you that technology is not a cloud, and my cloud is your cloud. At the same time, we should not be too conservative, too confident in the old method and wait for others to help you with the advance test. It is a good habit to

To complete the results shown in the following picture, there are many problems, one: backstage data is divided into two tables, a department table an employee table!
If thousands of employees, such a full load will make the data particularly slow! So it is more reasonable to use asynchronous loading.
But asynchronous loading because the data is placed in two tables, so involved, the problem of data loading source!
My idea is this, when the root node
