Failure in cloud system is defined as an even that occurs when the delivered service deviates from the correct intended service. As the cloud computing systems continue to grow in scale and complexity, there is an urgent need for cloud service providers (CSP) to guarantee a reliable on-demand resource to their customers in the presence of faults thereby fulfilling their service level agreement (SLA)...
The detailed designs, technologies and implementations of cloud storage are presented, including the multi-tenant concurrency, separated framework between buffer and business etc. Master/Workers partition algorithm is adopted to improve the reading and writing efficiency for big data in the cloud storage. A cross-platform interface is provided by using RESTful API. Meta files and their permissions...
Software Defined Networking (SDN) gives idea about including programming to the network with the opportunity to dynamically actions to be performed related to flow descriptions. Packet Header is the first phase of this process. In this concept, we illustrate improved action detection over conventional algorithms. This is achieved by analyzing various packet parameters (header fields of packet such...
Recently Cloud based Hadoop has gained a lot of interest that offer ready to use Hadoop cluster environment for processing of Big Data, eliminating the operational challenges of on-site hardware investment, IT support, and installing, configuring of Hadoop components such as HDFS and MapReduce. On demand Hadoop as a service helps the industries to focus on business growth and based on pay per use...
One of the primary usage of cloud computing is data storage. Cloud provides enormous capacity of storage for cloud users. Secure data storage and retrieval of the relevant information from the in traditional as well as in cloud computing environment has always been a significant issue. Different techniques have been developed for this purpose, with objective that it is more reliable and flexible to...
The growth in data traffic within higher institutions has always been accompanied with the adoption of a more scalable IT infrastructure. With the increasing budgetary constraints, cloud computing (a disruptive technology) presents an attractive means to address the scalability challenges while realizing the potential of ubiquitous IT services. The on-demand business proposition of the cloud provides...
A company's IT infrastructure delivers the basic hardware, networking, operating system, and middleware support to the business' applications. IT service providers perform incident and problem resolution, as well as user administration and change implementation required to maintain the availability and service provided for the business. As a result, they become increasingly challenged with delivering...
Knowing and optimizing the environmental impact of business processes is gaining momentum for today's organizations. However, there is a lack of solutions that guide and support organizations in determining the power consumption of automated business processes, considering the resources and services used by that process. In this work we propose a comprehensive, multi-phased methodology and corresponding...
There are several layers of virtualization, which can be combined with ERP installations. The most popular form is the processing virtualization or hyper-visoring. Our study collects the advantages of the different virtualization layers (sometimes referring to products, solutions) from business application point of view. Application virtualization layer is detailed a bit more than the others, because...
Multi-tenant applications are usually cloud based software services which can serve different users at the same time. This is done using single instance of applications by sharing hardware, infrastructure, data storage and virtualization. To achieve multi tenancy different approaches are there at every layer (Application, Data, hardware). Software-as-as-Service (SaaS) is a new approach for developing...
Today, many organizations are concerned with keeping their information infrastructure running smoothly and ensuring that users have continuous access to fundamental resources, even in the face of disasters and disruptions. Citrix Xenserver provides a robust set of virtualization technologies to help improve the resilience and usefulness of an organization's in order infrastructure, ensure that not...
Due to incremental upgrade approach, growing number of enterprise systems present heterogeneous UIs, in which certain sections/applications are 32 bit whereas others are 64 bit. Typical business process use-case interactions in these enterprise systems span both these sections, simultaneously. However conventional test automation tools have been designed to test either 32 bit applications or 64 bit...
The success of cloud computing would not be possible without the advances in virtualization. The basic concept is to have one resource pretend to be another. Its implementation is applicable to many areas of computing. Virtualization allows a computer to become several different computers, or one software package to emulate another. Although virtualization technology has been around for many years,...
In resent years, with the rapid development of Internet, the effective utilizing of Internet resources are becoming a problem. In order to utilize resources in the Internet effectively, cloud computing architecture is proposed. Cloud computing conception, related technology and key characteristics are introduced. The basic principle and reality mechanism of Cloud computing are summarized, Further...
The rapid increasing of variety and quantity of business brings about serious challenge to the server resources of datacenters. It is difficult for the traditional solution of server running and management to tackle with the changing need of services. The physical server sprawl leads to shortage of computer rack and room space. Meanwhile, the energy consuming increases, so do the difficulty of the...
The domestic platform is composed of the independent and controllable software and hardware equipment, such as CPU, operating system, database and middleware. In order to promote the application of the domestic platform, the simulation verification environment and the integration verification technology are deeply studied in this paper. Firstly, this paper designs the target model of the simulation...
Enterprises use design best practices to build applications that leverage the linear scalability of the cloud. These include methods like data sharding, application sharding, denormalized data stores, thin binary images etc. The design practices itself involve reengineering an application to the cloud. Enterprises view reengineering activities as a business risk and a costly affair. As Service oriented...
Nowadays, software is regarded not only as a product but also as a kind of service provided to the end users. Software as a Service (SaaS) model is gradually adopted by more and more enterprises. It reduces the cost of hardware, maintenance, updating and many other services for end users. It enables users focus on their business areas. The model also enables software providers provide services to...
This technical paper addresses the evolution of telecommunications services through the implementation of Cloud Computing technology using an Infrastructure-as-a- Service (IaaS) service model to build a Private cloud for Communication Service Providers (CSP). The paper will share a number of advances Nokia Siemens Networks has made within the area of Cloud Computing and its evolution strategy, and...
To solve the problems of business database services such as storage capacity, performance, stability, security, load, and many other issues, cloud storage was used to provide the cloud-based data platform. Data services were put on the cloud, and the powerful operating system and platform were used to process data. This article describes the architecture of cloud storage and presents the deployment...
