Virtual Machine Allocation

As a result of the dynamic nature of Virtual Machine allocation in cloud computing, it is not easy to manage system resources or choose the best configuration based solely on human experience.  In this work, we used stochastic modelling instead of comprehensive experiments to evaluate the best resource management of the system. In such complex systems, choosing the best decision is a challenge, for this reason we have designed a heuristic algorithm, specifically, dynamic programming as a resource management and programming tool that finds a way that attempts to satisfy the conflicting objectives of high performance and low power consumption. As a scenario for using this algorithm, we addressed the problem of virtual machine allocation, a subset of physical machines is designated as "reserve", and the reserves are actives when the number of jobs in the system is sufficiently high. The question is how to decide when to activate the reserves. The simulation results demonstrated the benefit of using our framework to identify the policy for consolidation or for a low energy consumption and in order to have a good quality of service in the system

Perkembangan teknologi komputasi saat ini luar biasa sangan pesat, tak sedikit sebuah server yang dulunya hanya dimanfaatkan untuk menangani satu layanan saja, kini hal itu sudah di anggap sebagai pemborosan resource, salah satu penyebabnya adalah perkembangan metode virtualisasi yang di anggap dapat mengoptimalkan sebuah server untuk menangani lebih banyak layanan dengan cara membuat beberapa mesin virtual dalam satu mesin real untuk memaksimalkan kemampuan server, lalu apakan dalam sebuah mesin virtual dapat menjalakan mesin virtual lagi, amankah bila digunakan untuk menangani layanan sistem informasi secara optimal.  Kata Kunci- Virtualisasi Bersarang, E-Learning, High Availability.   The development of computing technology is currently very fast, not a few servers that were previously only used to handle one service, now it is considered a waste of resources, one of the causes is the development of virtualization methods which are considered to optimize servers for more services by creating several virtual machines in to one real machine to maximize server capabilities, so in a virtual machine can it run the virtual machine again, is it safe to using it for optimal information system services.  Keyword- Nested Virtualization, E-Learning, High Availability.

Cloud computing is a powerful technology of computing which renders flexible services anywhere to the user. Resource management and task scheduling are essential perspectives of cloud computing. One of the main problems of cloud computing was task scheduling. Usually task scheduling and resource management in cloud is a tough optimization issue at the time of considering quality of service needs. Huge works under task scheduling focuses only on deadline issues and cost optimization and it avoids the significance of availability, robustness and reliability. The main purpose of this study is to develop an Optimized Algorithm for Efficient Resource Allocation and Scheduling in Cloud Environment. This study uses PSO and R factor algorithm. The main aim of PSO algorithm is that tasks are scheduled to VM (virtual machines) to reduce the time of waiting and throughput of system. PSO is a technique inspired by social and collective behavior of animal swarms in nature and wherein particles search the problem space to predict near optimal or optimal solution. A hybrid algorithm combining PSO and R-factor has been developed with the purpose of reducing the processing time, make span and cost of task execution simultaneously. The test results and simulation reveals that the proposed method offers better efficiency than the previously prevalent approaches.
