In General, the analytical models were geared towards the models that use the cloud and its services through the performance of the model, and the current model was analyzed and evaluated for various configurations and assumptions. Starting as a database service provider, nowadays cloud computing also provides software, applications, platforms, and full functioning IT infrastructures for the clients. In an on-premises, host-based IT setting, enterprises must deliver properly tuned resources to meet performance goals. SLAs force IT managers to focus on three major areas: Data protection, continuity and cost. Interested in research on Cloud Computing? The proof of ownership is based on three aspects: (i) the level of security, (ii) public auditing, and (iii) performance. fixed and only the number of data centers is changed from. Gartner expects the public cloud market will total over $208 billion by the end of this year. the data centers and users are in the same region or are far from each other in different regions . Any enterprises adopting cloud computing services certainly expect the kind of improved performance that an elastic computing environment should provide. adopts the concept of virtualization, service oriented architecture, autonomic, and utility computing. This paper presents an extensive performance study of network I/O workloads in a virtualized cloud environment. To build a high-performance computing architecture, compute servers are networked together into a cluster. also increase. WANs, if used properly, can actually improve the speed of connection to cloud connections. In high-performance computing, GPUs are better than CPUs alone because they have thousands of small, efficient cores that are designed to process information faster. is due to the chart level rise for this state, as can be shown in Figure 4. Cloud is the important model for access to distributed computing resources, And the data recovery, lack of control over cloud services, service level agreements, legal. The term of “moving to cloud” refers to an organization moving away from traditional, Cloud computing is a computing model of providing IT resources, such as application, infrastructure, and platform in the form of service by using Internet. Current and future technologies applied in cloud computing are also discussed. A simulation of the aforementioned model is used to study, analyze, and evaluate both the performance Evaluation based on criteria and characteristics, Recovery, when data in cloud face errors and failures or data are lost for any re. Disk capacity, can also have a negative or positive impact on performance in cloud[17]. they also use enterprise resource planning systems in order to move towards process oriented Enterprises. In the meanwhile, it limits costs generated by the management of these data. This insight into the essential characteristics of cloud and its enabling technologies provides a good foundation for understanding and a hint on how to leverage desirable strengths of these technologies in the cloud by way of extension and or inheritance. How a department handles the questions that arise from these areas can be indicative of how well the vendor can service a client. But an SLA for cloud can help improve performance because it addresses an expected range of availability and performance. Advances in virtualization, storage, connectivity and processing power are combined to create a new ecosystem for cloud computing. computing environment are the major disadvantages of cloud computing [1-5]. These frequently asked questions on cloud computing performance offer advice on lessening performance concerns, understanding the relationship between service-level agreements (SLA) and performance, and the standards slowly developing in the cloud computing world. The advantages of using cloud computing include cost savings, speed to market, access to greater computing resources, high availability, and scalability. However, this advanced technology has immediately highlighted many serious security troubles. capacity is low, many requests will be rejected and therefore performance will be low. Cloud computing is the fruit of recent developments in information technology, it provides access to many online services as well as remote computing resources as needed. Some of the important factors considered in this paper are as follows: risks threaten cloud environment, it will be a big concern for users and providers. and the overall cost of two major gang scheduling algorithms. When people refer to performance, especially in the context of cloud computing they typically refer to price-to-performance ratio (how much can I process in a given unit of time for x amount of money) rather than pure performance as in the athletic sense (I have the fastest supercomputer in the world). Other factors that can affect performance which are as follows: mentioned that all of criteria listed in pe. Copyright 2010 - 2020, TechTarget But cloud services are not perfect. Though there isn't yet a good deal of "quantifiable information" on cloud, many independent researchers and analysts are beginning to look at cloud and compile some cloud computing benchmarks. If you're looking for more information on cloud providers, CloudHarmony.com has generated thousands of results on the different configurations available to consumers. Cloud computing is changing the way applications are deployed, monitored, and used by the end–users. Cloud computing is an emerging technology. See how Cycle Computing has developed a platform for running for running small- to large-scale clusters by using the AWS Cloud for high performance computing. Some of the most important standards have been considered while others are still under identification or under development. Customers like Bristol-Myers Squibb, FINRA, BP and Autodesk trust AWS to run their most critical HPC workloads. This book presents the systems, tools, and services of the leading providers of cloud computing; including Google, Yahoo, Amazon, IBM, and Microsoft. The results of this analysis would be more serious considering the organizations' expectation for a huge increase in performance against cost paid, investments performed and huge change in their organizations. Pareto traffic was considered for the offered traffic. Keeping Resources in the cloud environment can be helpful in saving infrastructure cost and time for the user. As an example, increasing power and speed of the data center is not always efficient. In this paper we present an approach for performance evaluation of cloud computing configurations. Complex dependencies may exist between servers in various tiers. Results reveal that Gang Scheduling can be effectively applied In this paper, we review current state of cloud computing research and technology with emphasis in the adoption of cloud computing in the healthcare information system, and also discuss a foundation for establishing a framework for cloud-based e-prescription system using cloud computing infrastructure. An architecture model captures the deployment configurations of multi-tier applications. This process is shown in figure 1. into cloud servers which is described in following: 4. conclusions. performance evaluation may be based on different providers too [7]. Finally, we analyze the impact of different CPU resource scheduling strategies and different workload rates on the performance of applications running on different VMs hosted by the same physical machine. If you're looking to gain more computing power, you can speed up this process by pulling some resources down off the cloud. It can be concluded that increasing number of data centers is not, impact and only will increase cost. to an off-site, location-transparent centralized facility or “Cloud.” Gang Scheduling is an efficient job scheduling algorithm We present a novel approach for offline Persian/Arabic intelligent word recognition based on the fast and customized dynamic time warping method. can access to infrastructures with virtual machine [12]. High-performance cloud computing (HPC2) is a type of cloud computing solution that incorporates standards, procedures and elements from cloud computing. Software programs and algorithms are run simultaneously on the servers in the cluster. Multi-tier cloud applications can have complex deployment configurations with load balancers, web servers, application servers and database servers. On the other hand, modern Enterprises looking for standard structures and they. information of the enterprise onto the cloud contains lots of security issues and threats. that can be effective on performance from the users’ view. In this paper the concepts of Cloud Computing like cloud deployment models, delivery models, advantages of using cloud and risks involved in it are analysed.
