TL;DR: This work proposes a reusable architecture that enables the self-configuration of a supporting infrastructure for Web server clusters using virtual machines to ensure service quality and to be flexible enough to accept, with a reasonable amount of effort, different resource self- configuration policies.

TL;DR: This paper addresses the architecture and integration issues of the contract‐based approach, as well as how to put the pieces together highlighting deployment and implementation details, which have to consider diverse aspects such as monitoring, security and dynamic reconfiguration.
Abstract: Resource management is an important aspect to consider regarding applications that might have different non-functional or operational requirements, when running in distributed and heterogeneous environments. In this context, it is necessary to provide the means to specify the required resource constraints and an infrastructure that can adapt the applications in light of the changes in resource availability. We adopted a contract-based approach to describe and maintain parallel applications that have non-functional requirements in a Computing Grid context, called ZeliGrid. To form the supporting infrastructure we have designed a software architecture that integrates some of the Globus services, the LDAP and the NWS monitoring services. Some modules that map the contract approach into software artifacts were also integrated to this architecture. This paper addresses the architecture and integration issues of our approach, as well as how we put the pieces together highlighting deployment and implementation details, which have to consider diverse aspects such as monitoring, security and dynamic reconfiguration.

TL;DR: This work proposes a reusable architecture that enables the management of a supporting infrastructure for Web server clusters using virtual machines and shows how advantageous it can be in terms of using resources, avoiding waste, yet maintaining the application's service within acceptable quality failure levels.
Abstract: This work proposes a reusable architecture that enables the management of a supporting infrastructure for Web server clusters using virtual machines. The goal of the architecture is to ensure service quality, evaluating how broadly it complies with the operating restrictions (maximum response time) and proportionally acting on physical servers (hosts) or manipulating the virtual machines. In addition, through the rational use of resources, the proposal aims at saving energy. A prototype of the architecture was developed and a performance evaluation carried out. This evaluation shows that the proposal is fully functional and how advantageous it can be in terms of using resources, avoiding waste, yet maintaining the application's service within acceptable quality failure levels.

TL;DR: This work proposes using a neural network with self organizing maps, to build a configuration policy, which enables the management of a supporting infrastructure for Web applications using virtual machines.
Abstract: This work proposes using a neural network with self organizing maps, to build a configuration policy, which enables the management of a supporting infrastructure for Web applications using virtual machines. The neural network classifies the cluster´s operation states to perform configuration operations adding or subtracting resources from the cluster. The overall goal is to ensure quality of service required by the application, while trying to save energy, acting efficiently on physical servers (hosts) or manipulating the VMs. The work includes a performance evaluation carried out over a system implemented based on the proposed architecture.

TL;DR: An SLA-aware (Service Level Agreement aware) framework is proposed for cloud service (cloud infrastructure) delivery, and making allowance for the benefit of stakeholder of cloud service provider and service consumer by using the proposed system and hierarchy SLA monitoring model.
Abstract: Cloud computing has emerged as a new paradigm, which is the long-held dream of computing as utility, customer get it on an on-demand model. When discuss about performance requirement and QoS (Quality of Service) of service, it is hard to tackle these problem in a round consideration. In this work we propose an SLA-aware (Service Level Agreement aware) framework ¨C cloud service provider (CSP) for cloud service (cloud infrastructure) delivery, and making allowance for the benefit of stakeholder of cloud service provider and service consumer. By using our proposed system and hierarchy SLA monitoring model we reached our win-win objective which is maximum revenue of cloud provider and minimum SLA violation.

TL;DR: Web server Apache dapat diimplementasikan di jaringan enterprise Jurusan Teknik Informatika dan Komputer Politeknik Negeri Jakarta wedi dibutuhkan sebuah komputer server sebagai wadah dari web server yang dap at dimanfaatkan bagi pengguna individu maupun penggunakan kelompok.
Abstract: Proses pertukaran data dan informasi masih terhambat dikarenakan belum terpusatnya sumber informasi dan data yang dibutuhkan Jurusan Teknik Informatika dan Komputer Politeknik Negeri Jakarta. Oleh karena itu dibutuhkan sebuah komputer server sebagai wadah dari web server yang dapat dimanfaatkan bagi pengguna individu maupun pengguna kelompok. Dengan perkembangan internet dan pengguna website semakin besar serta salah satu alasan memberikan cara yang mudah dan cepat dalam mengirimkan data dan informasi. Web server memenuhi kebutuhan untuk menopang website , email , dan lain-lain, serta untuk mempercepat dan mengorganisasi informasi dan data secara terpusat yang kemudian diimplementasikan pada jaringan enterprise Jurusan Teknik Informatika dan Komputer Politeknik Negeri Jakarta. Kinerja dari web server Apache dan Nginx untuk mengetahui manakah yang lebih unggul dari kedua web server tersebut. Metode yang digunakan adalah studi literatur mengenai web server , diskusi dan pengamatan upaya untuk menentukan software yang paling tepat digunakan untuk web server , dan pengujian. Dari tahapan yang dilakukan dapat disimpulkan bahwa web server dangan menggunakan Apache lebih unggul dibandingkan dengan web server yang menggunakan Nginx, kinerja Apache dalam transfer data, Connection , dan request data lebih baik sehingga memudahkan client dalam mendapatkan informasi yang dibutuhkan. Dengan kelebihan kecepatan transfer rata–rata 701 Kbytes/sec, web server Apache dapat diimplementasikan di jaringan enterprise Jurusan Teknik Informatika dan Komputer Politeknik Negeri Jakarta.

TL;DR: In this article, the authors proposed a method of provisioning a cloud-based render farm using a provisioning module and/or a controller, which can be used to assign jobs to a render farm by dragging and dropping a job icon onto the render farm icon on user interface.
Abstract: This invention relates to a method of provisioning a cloud-based render farm. Cloud- based render farms are relatively difficult to establish and require skilled IT personnel to create and operate. This represents a significant cost to smaller 3D studios and a substantial drain on the resources of the larger 3D studios' IT departments. According to the present invention, the steps of establishing a cloud-based render farm are simplified through the appropriate use of a provisioning module. All that is required of the IT staff or artist is to nominate the number of render machines and the amount of storage area required in the render farm and in some instances the rendering software and plugins required. The remaining steps of the method are performed by the provisioning module and/or a cloud-based render farm controller. In this way, cloud-based render farms can be established quickly with the minimum amount of difficulty and skill required. Once created, rendering jobs can be allocated to a render farm by dragging and dropping a job icon onto a render farm icon on a user interface.

TL;DR: Temporal dynamic policies may be used to effectively alter the management of a virtual machine in a virtualized computing environment based upon some temporal condition such as how long a VM has been active or idle, how long it has been since the virtual machine was created or deployed, etc.
Abstract: Temporal dynamic policies may be used to effectively alter the management of a virtual machine in a virtualized computing environment based upon some temporal condition such as how long a virtual machine has been active or idle, how long it has been since the virtual machine was created or deployed, etc. The altered management may be used, for example, to activate various performance and/or reliability-related technologies such as high availability and failover functionality for longer-running virtual machines.
