Single Web server would become a bottleneck that influences the availability and stability of Web service. Ten years ago, what had been proposed is to add Web servers for resolving this problem—Web Server Cluster. In recent years, the concept of cloud computing has got rapid development, and is becoming the future development trend of the IT industry. One of the characteristics of cloud computing is putting lots of computing resources together to provide users with a unified service. In this paper, we have proposed a new Cloud-Based Web Server Cluster Solution, based on the existing cloud computing model—Twitter Storm. It involves a new way to handle the web request from client and some other new features compared to the traditional Web Server Cluster. Combining with cloud computing, it would be the new trend of Web Server Cluster, and its feasibility is described in the paper too.
With the large-scale development of Chinese electric
power, the contradiction of China’s energy supply and demand that reverse
distributed is very prominent, therefore, promoting electricity trading is one
of the important measures to get optimized configuration of energy resources in
nationwide. For the two kinds of trading method, the “power point to the
grid” trading and the “grid to grid” trading, this paper designed pricing
mechanism model, and took one area as an example, we analyzed the impact of the
participants by using different pricing mechanism, and put forward reasonable
policy proposals for China’s pricing mechanism of trans-regional and
trans-provincial electricity trading.
