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.

Private cloud computing enables you to consolidate diverse enterprise systems into one that is cloud-based and can be accessed by end-users seamlessly, regardless of their location or changes in overall demand. Expert authors Steve Smoot and Nam K. Tan distill their years of networking experience to describe how to build enterprise networks to create a private cloud. With their techniques you?ll create cost-saving designs and increase the flexibility of your enterprise, while maintaining the security and control of an internal network. Private Cloud Computing offers a complete cloud architecture for enterprise networking by synthesizing WAN optimization, next-generation data centers, and virtualization in a network-friendly way, tying them together into a complete solution that can be progressively migrated to as time and resources permit."--pub. desc.

It may seem a strange place to start, but a good beginning here is the Boston Marathon bombings in April, 2013 and the days that followed. In particular, the Friday when officials shut down the city of Boston and neighboring communities. Businesses all over the city were forced to shut down while the manhunt took place over the course of the day on Friday. While retail establishments were really out of luck because no one on the streets meant no one in the stores, other businesses were able to continue to operate because of a number of technologies that allowed remote workers to get access to their files, the systems they needed and their phone systems. Any business that implemented a full Unified Communications (UC) solution could have employees also communicating with instant messaging and know who was on-line because of the presence capabilities. Additionally, news of the events spread quickly and less because of news outlets who were, quite rightly, not allowed to provide specifics about many of the activities"-- Provided by publisher.

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.

Private Cloud merupakan pemodelan teknologi Cloud Computing yang hanya memberikan layanan kepada pengguna tertentu. Kebutuhan akan performa server yang baik, tentunya mempengaruhi layanan yang ditawarkan suatu provider cloud kepada penggunanya. Oleh karena itu, pembuatan Cloud Computing dengan memilih layanan Private Cloud pada skripsi ini dilakukan dengan membuat simulasi nyata pada jaringan fisik menggunakan CentOS dengan Eucalyptus di dalamnya. Metode instalasi menggunakan konfigurasi Cloud in a Box. Lima pengujian diimplementasikan untuk mengetahui performa server Private Cloud ini. Instances dibuat sibuk seolah-olah menjalankan sebuah aplikasi sehingga terlihat kinerja dari server cloud. Parameter pengujian yang digunakan untuk pengukuran performa server adalah Load Average, CPU Usage dan Memory Usage. Dari hasil pengukuran menunjukkan bahwa parameter Load Average dengan load tertinggi sebesar 4,35 satuan proses dan CPU Usage tertinggi mencapai nilai 95,04% ketika seluruh instance aktif menjalankan aplikasi. Memory usage server mencapai 4740,95 MB dan untuk seluruh instance menggunakan memori sebesar 29,37% dari penggunaan memori pada server. Tiga parameter di atas menunjukkan kesesuaian server cloud dalam menangani pengguna pada jaringan privat IaaS ini dengan konsep Cloud IaaS pada umumnya. ......Private Cloud is a technology model of Cloud computing that only provide service to a particular user. Requirement for a good server performance, of course, affect the service offered to the user of a cloud provider. Therefore, making cloud computing by choosing a Private Cloud service in this thesis was to create a simulation of the real physical network using CentOS with Eucalyptus in it. Installation method using configuration Cloud in a Box. Five tests are implemented to determine the performance of the server's Private Cloud. Instances kept busy as running an application and visible the performance of the server cloud. Testing parameters used to measure the performance of the server is the Load Average, CPU Usage and Memory Usage. From the measurement results indicate that the parameter Load Average with the highest load of 4.35 units and the highest CPU usage reaches 95.04% when all active instances running the application. Memory usage of server and to achieve 4740.95 MB memory instances amounting to 29.37%. Three parameters above indicates suitability of cloud servers to handle the user's private network to the concept of Cloud IaaS IaaS in general.
