Perkembangan teknologi informasi saat ini sudah mengalami kemajuan yang sangat pesat dalam jangka waktu yang cukup singkat, hal itu memicu pengembangan aplikasi yang memanfaatkan sistem cloud computingkarena mampu mengefisiensikan pengeluaran biaya dan sumber daya yang digunakan untuk aplikasi. Pada penelitian ini dilakukan pengujian performansi pada SIMPLE-O yang diterapkan pada cloud computing. Dari hasil dua pengujian performansi SIMPLE-O didapatkan bahwa untuk pengujian dengan metode GET yaitu pada saat pengguna hanya mengakses halaman utama dari aplikasi, performansi SIMPLE-O pada layanan cloud computing lebih baik dibandingkan dengan shared hosting, dimana cloud computing mengalami error sebesar 1,70 % dari 6000 request yang terkirim dengan response time rata-rata sebesar 32,62 s. Sementara shared hosting mengalami error sebesar 18,04 % dari 6000 request yang terkirim dengan response time rata-rata sebesar 36,27 s. Namun untuk pengujian dengan metode POST yaitu pada saat aplikasi SIMPLE-O melakukan proses penilaian otomatis terhadap jawaban yang dikirimkan, performansi SIMPLE-O pada layanan cloud computing sedikit lebih buruk dbandingkan dengan shared hosting, dimana cloud computing mengalami error sebesar 1,60 % dari 1000 request yang terkirim dengan response time rata-rata sebesar 63,95 s. Sedangkan shared hosting mengalami error sebesar 0,30 % dari 1000 request yang terkirim dengan response time rata-rata sebesar 52,67 s.

The development of information technology have progress very rapidly in a relatively short period of time, it triggers the development of applications that take advantage of cloud computing systems because have more efficient cost and resource for application.From the results of two performance testing SIMPLE-O, for the testing with GET method it was found that when the user only access the main page of the application, the performance of SIMPLE-O in cloud computing services is better than shared hosting, where cloud computing has an error by 1.70% from the 6000 request that sent with average response time in 32,62 s. While shared hosting has an error by 18.04% from the 6000 request that sent with average response time in 36,27 s. However, for testing with POST method, that when the application SIMPLE-O doing aautomatic process to assessment the exam’s answer from the user, the performance of SIMPLE-O in cloud computing services slightly worse than shared hosting, where cloud computing which has an error by 1.60% from 1000 request that sent with average response time in 63,95 s. While shared hosting has an error by 0.30% from 1000 request that sent with average response time in 52,67 s.

As part of the Syngress basics series, The basics of cloud computing provides readers with an overview of the cloud and how to implement cloud computing in their organizations. Cloud computing continues to grow in popularity, and while many people hear the term and use it in conversation, many are confused by it or unaware of what it really means. This book helps readers understand what the cloud is and how to work with it, even if it isn’t a part of their day-to-day responsibility. Authors Derrick Rountree and Ileana Castrillo explains the concepts of cloud computing in practical terms, helping readers understand how to leverage cloud services and provide value to their businesses through moving information to the cloud. The book will be presented as an introduction to the cloud, and reference will be made in the introduction to other Syngress cloud titles for readers who want to delve more deeply into the topic.

Tesis ini menelusuri peran representasi dalam perancangan arsitektur. Dengan memahami mekanisme pada penggunaan media representasi, arsitektur dapat dipahami sebagai proses translasi antara ide dan material. Penggunaan media representasi secara tidak langsung mempengaruhi bagaimana proses translasi antara ide dan material tersebut terjadi. Transformasi yang terjadi pada representasi ini dipandang sebagai potensi yang patut ditelusuri. Penelusuran dilakukan secara teoritikal dengan memanfaatkan fotografi sebagai media representasi yang telah populer saat ini. Penelusuran berakhir pada penggunaan 'spatial cloud' sebagai alternatif dalam melihat ruang pada arsitektur secara lebih subjektif dan kontingen dengan memanfaatkan fragmentasi yang terjadi pada representasi. Pada akhirnya, proses penelusuran ini merupakan suatu cara lain untuk memahami arsitektur dan dapat dimanfaatkan untuk membuka peluang-peluang spasial baru dalam perancangan arsitektur. ......This thesis invetigates the role of representation in architecture. By understanding the mechanism within representation, architecture is understood as a translation between ideas and materiality. This translation is indirectly affected by the representation which is seen as a kind of possibility of transformation. Thereby, this transformation inevitably becomes a kind of possibility of architecture. The investigation is conducted theoritically using the representation of photograph which is already a popular medium in our everyday life. By identifying the fragmentation in the process of representing, the investigation results in 'spatial cloud' as alternative in seeing the space in architecture in a more subjective and contingent way. Finally, this investigation of representation becomes an alternative way to understand architecture which can be used to open spatial possibilities in architectural design.

Cloud Computing merupakan suatu perubahan besar yang terjadi di dunia komputasi dan internet. Teknologi Cloud kini sudah banyak diaplikasikan pada jaringan riil salah satunya yaitu Private Cloud. Pembuatan Cloud Computing dengan memilih layanan Private Cloud dengan membuat simulasi nyata pada jaringan fisik menggunakan Eucalyptus dengan sistem operasi CentOS 6.4. Pengujian dilakukan suatu variasi terhadap jumlah pengguna yaitu satu dan tiga pengguna. Selain jumlah penggunanya, besaran ukuran file juga diuji yaitu 100 MB, 200 MB, dan 300 MB dengan perbandingan sebelum dan setelah penyerangan Denial of Service (DoS) untuk proses data upload dan download. Hasil penelitian didapat bahwa dengan melakukan pengukuran Quality of Service (QoS) dengan menggunakan packet loss, delay, dan throughput yang dilakukan pada saat uji coba pengiriman data menggunakan aplikasi File Transfer Protocol (FTP). Hasil pengukuran menunjukan bahwa serangan DoS cukup berpengaruh untuk pertukaran data untuk proses upload terutama untuk 1 user daripada 3 user dengan masing-masing penambahan packet loss, delay, dan pengurangan throughput terbesar memiliki persentase 169.57%, 22.79%, dan 20.08%. Kemudian pengujian berdasarkan proses download, serangan DoS cukup berpengaruh untuk 3 pengguna dengan persentase penambahan packet loss sebesar 36.51%, penambahan delay sebesar 148.48% dan untuk penurunan throughput didapat pada pengujian 1 user dengan persentase sebesar 21.25%. Dari persentase ini dapat disimpulkan bahwa proses download memiliki sedikit pengaruh terhadap serangan DoS.

Cloud Computing is a big change happening in the world of computing and the Internet. Cloud technology is now widely applied to real networks one of which is Private Cloud. Development of Cloud Computing with select the Private Cloud services make a real simulation of the physical network using Eucalyptus with operating system of CentOS 6.4. Testing is done with the variation of the number of users is one and three users. In addition to the number of users, scale file size also tested is 100 MB, 200 MB, and 300 MB with comparison before and after the Denial of Service (DoS) attack to process data upload and download. The results found that by measuring Quality of Service (QoS) by using packet loss, delay, and throughput is conducted at the time of trial data transmission using File Transfer Protocol (FTP) application. Based on upload process, measurement results showed that the DoS attack is quite powerful for data transmission one user than three users with additional packet loss, delay, and reduction of throughput have a percentage of 169.57%, 22.79%, and 20.08% with a file size of 300 MB. Then testing based on download process, DoS attack quite influential for 3 users with percentage with additional packet loss in athe amount of 36.51%, increase delay time is 148.48% and for reduction of throughput obtained on 1 user testing with percentage is 21.25%. With this percentage we can get conclusion that download process have a few influence with DoS attack.
