A Web crawler is an important component of the Web search engine. It demands large amount of hardware resources to crawl data from the rapidly growing and changing Web. The crawling process should be performed continuously to maintain up-to-date data. This paper develops a new approach to speed up the crawling process on a multi-core processor by utilizing the concept of virtualization. In this approach, the multi-core processor is divided into a number of virtual-machines (VMs), which can concurrently perform different crawling tasks on different initial data. It presents a description, implementation, and evaluation of a VM-based distributed Web crawler. The speedup factor achieved by the VM-based crawler over no virtualization crawler, for crawling various numbers of documents, is estimated. Also, the effect of number of VMs on the speedup factor is investigated.

With the development of cloud computing, more and more enterprises are building their own cluster to deploy various types of distributed systems on the public cloud to satisfy their growing business need. In the process of migrating the business to the cloud, the enterprise faces two problems. The one is that the rental of virtual machines on the public cloud is a complicated process. Users need to understand and select a variety of parameters while the parameters of different public clouds are not the same. The other is that deployment and scale-out of distributed systems remain complex for inexperienced users. To address the above problem, this paper designs and implements a method for automatically deploying and scaling out Docklet, which is a typical distributed system, on the cloud from scratch. Finally, we present several examples to show the effectiveness.

Service-oriented business process construction is a technology that Web service components are directly mapped to the visualization graphical components. business people are allowed to construct main logic structure of the business process through dragging and dropping the graphical components, then platform automatically generates BPEL elements and attributes by parsing WSDL. The BPEL elements and attributes which platform could not automatically generate will be specified by business people with help of user-friendly visual interface. In addition, it's necessary to display available variables for business people in order to copy data from one variable to another. However, when the scale of business process is very large, it's unfeasible to show all available variables for business people. To solve this problem, in this paper, we propose and prove two theorems used to filter out some variables, and the remaining variables are sorted in accordance with similarity among the variables so that make business people are able to quickly navigate the variables needed. In this way, platform hides some details of BPEL language for business people. Therefore, as long as business people are familiar with the business knowledge, they could use platform to construct business process that meets the needs of business. Thus speeding up the development efficiency of business process and reducing cycle of business process reconstruction.
