With the growing of Internet, people use network frequently. Many PC applications have moved to the network-based environment, such as text processing, calendar, photo management, and even user can develop applications on the network. Google is a company providing web services. Its popular services are search engine and gmail which attracts people by short response time and lots amount of data storage. It also charges businesses to place their own advertisements. Another hot social network is Facebook which is also a popular website. It processes huge instant messages and social relationships between users. The magic power of doing this depends on the new technique, Could Computing. Cloud computing has ability to keep high-performance processing and short response time, and its kernel components are distributed data storage and distributed data processing. Because of the new concept, there are fewer application, such as pattern searching and log file analysis, related to the cloud computing. Therefore, we use the technique to perform the packet analysis and packet dissection. The packet data are placed by distributed file system, and further process according to different requirements, which acts as IPS (Intrusion Protection System).
