present, another kind of webserver has emerged, which is superior in terms of concurrency, called asynchronous servers Asynchronous Server. The most famous ones are nginx and Lighttpd. The so-called Asynchronous Server is the event-driven in the event-driven mode. In addition to the user's concurrent requests, only one or several threads are required. Therefore, system resources are very small. These are also called lightweight Web

Proper virtualization implementation and management means cost savings, including the cost of server hardware, support, and management. This also simplifies server deployment and reduces energy consumption. To fully benefit from these benefits, stack virtualization-level management must be independent of applications or physical servers.
Fortunately, if the management is in place, it is not difficult to be independent.
Indeed, in the virtual world, se

1. Cluster Technology
Cluster technology is a new high-performance computing technology in recent years. It is a single computer system composed of a group of independent computers through high-speed communication networks and managed in a single system mode. Its starting point is to provide high reliability, scalability, and disaster resistance.
A server cluster contains multiple servers with shared data storage space, and each Server communica
Traditionally, servers can be divided into many types based on different criteria. For example, different processors and architecture can be divided into x86 servers, GPU servers, CPU-level computers, and large hosts. Based on different performance levels, it can be divided into entry-level servers, working group-level
