Brief introduction
Because each execution server is unique, a concept quickly emerges: Install and configure the image once, and then replicate and reuse it again and again. This uniqueness may be reflected in small areas such as different passwords and IP addresses, or in large areas such as different software and application requirements. To achieve the efficiency of the image commitment, you must carefully consider what to put into the image and how many images to build.

security. In addition, how do we choose servers? With the highly available cluster environment of server load balancer, we can assemble servers by ourselves, which is the most cost-effective. Although the quality of branded servers such as IBM and DELL is guaranteed, the price is often unacceptable to the boss. Of course, everything is based on stability.
First, select the server load balancer device. We can have two options: one is through hardware. common hardware includes expensive
Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load balancer and executes Server Load balancer tasks based on information in the header, therefore, the network dependency is relatively small. Theoretically,

Choose a good file system, this now I just choose ext3, after all very mature, and JFS, EXT4 or dare not directly use online.Site layeringSite layering, for large sites this is necessary, load balancer (LVS, Nginx, F5,netscaler), front-end Web server (Tomcat, Apache, resin, lighttpd, nginx, etc.), middle tier (such as memcached, ICE), Databases (Oracle, PostgreSQL, MySQL, etc.). This still needs to be planned before the program is developed. and the
