Building a Private Cloud Computing and The Analysis against DoS (Denial of Service) attacks Case Study at SMKN 6 Jakarta

The development of Cloud Computing is growing and becoming a trend that is widely used in the world of telecommunications today. In education, cloud computing becomes something that is needed to support the teaching and learning process. We analyze and design the network infrastructure in schools to implement cloud computing in local area schools. Then we built a system to create a server for cloud computing that can be accessed through the wired network and wireless network. Once the server cloud computing is installed and then we test functions such as uploading and downloading files whether to run well The next step is to perform the test by doing DOS (Denial Of Service). The results show when no server DoS attack goes well with a large throughput. However, after the DoS attacks decreased throughput value and the greater the number of attacks is increasingly reducing the throughput of the server cloud This shows that Cloud Server that have been built are still vulnerable to DoS attacks.
