A Performance Evaluation of Public Cloud Using TPC-C
نویسندگان
چکیده
Cloud is becoming the next-generation computing paradigm for enterprises to deploy services and run business. While most Cloud service providers promise some Quality of Service (QoS) through a Service Level Agreement (SLA), it is very hard for Cloud clients to know what impacts these QoS have on their businesses. In this paper, we study this issue by conducting a simple performance evaluation of two public Clouds. We selected TPC-C to benchmark three types of instances (Small, Medium and Large) provided by the Cloud providers in order to find out how the typical online transaction process systems perform on the cloud nodes. Our testing results show that the different Cloud environments deliver very different performance landscapes with different Cloud instances. Our work demonstrates the importance and opportunity to choose the appropriate Cloud instance in achieving an optimal cost-performance ratio for a class of cloud applications.

Architecture and Performance Characteristics of a PostgreSQL Implementation of the TPC-E and TPC-V Workloads
The TPC has been developing a publicly available, end-to-end benchmarking kit to run the new TPC-V benchmark, with the goal of measuring the performance of databases subjected to the variability and elasticity of load demands that are common in cloud environments. This kit is being developed completely from scratch in Java and C++ with PostgreSQL as the target database. Since the TPC-V workload...

Over the past decades, urban growth has been known as a worldwide phenomenon that includes widening process and expanding pattern. While the cities are changing rapidly, their quantitative analysis as well as decision making in urban planning can benefit from two-dimensional (2D) and three-dimensional (3D) digital models. The recent developments in imaging and non-imaging sensor technologies, s...
متن کاملA multi-scale convolutional neural network for automatic cloud and cloud shadow detection from Gaofen-1 images
The reconstruction of the information contaminated by cloud and cloud shadow is an important step in pre-processing of high-resolution satellite images. The cloud and cloud shadow automatic segmentation could be the first step in the process of reconstructing the information contaminated by cloud and cloud shadow. This stage is a remarkable challenge due to the relatively inefficient performanc...
متن کاملA novel method for locating the local terrestrial laser scans in a global aerial point cloud
In addition to the heterogeneity of aerial and terrestrial views, the small scale terrestrial point clouds are hardly comparable with large scale and overhead aerial point clouds. A hierarchical method is proposed for automatic locating of terrestrial scans in aerial point cloud. The proposed method begins with detecting the candidate positions for the deployment of the terrestrial laser scanne...
متن کاملCost-Effective Resource Configurations for Multi-Tenant Database Systems in Public Clouds
Cloud computing is a promising paradigm for deploying applications due to its large resource offerings on a payas-you-go basis. In this report, we examine the problem of determining the most cost-effective provisioning of a multitenant database system as a service over public clouds. We formulate the problem of resource provisioning, and then define a framework to solve it. Our framework uses h...
