Abstract
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.
Highlights
In the Web Server Cluster Solution based on Twitter Storm, the data processing is distributed to slave nodes by the master node, and the request will be guaranteed to be processed
Focused on the bottleneck problem caused by single Web server, the paper proposes a new Web Server Cluster Solution based on cloud architecture
With the existing cloud computing model—Twitter Storm, we have introduced the solution in detail and discussed the feasibility of the architecture
Summary
The core idea is integrating multiple Web applications on the same physical server cluster by splitting, merging and migrating the instances of Web application which is running on the cluster By this way, we can achieve a much higher server utilization rate. We presents a new Cloud-Based Web Server Cluster that addresses the problem faced by traditional Web Sever Cluster and can guarantee the physical server utilization rate for supporting PaaS. Ver, which means how to provide the same Web application service by more than one service entrances; 2) How to deal with the load balance and share state information between multiple physical servers; 3) How to support the cloud computing model of PaaS —there are multiple Web services on the same cluster, and there is only one instance for a Web service. The paper concludes the work and presents our future research plan
