Data Analysis in the Cloud - 747 Words

V. DATA ANALYSIS IN THE CLOUD In this section we descus the expected properties of a system designed for performing data analysis at the cloud environment and how parallel database systems and MapReduce-based systems achieve these properties. Expected properties of a system designed for performing data analysis at cloud: †¢ Performance Performance is the primary characteristic of database systems that can use to select best solution for the system.High performance relate with quality, amount and depth of analysis. High performance helps to reduce cost.Upgrading to a quicker software package will permit an organization avoid adding further nodes to application continues to scale. †¢ Fault Tolerance. In transactional workloads fault tolerant means that DBMS can recover from a failure without losing any data. In the distributed databases fault tolerances means that successfully commit transactions and make progress even in the worker node failures. For read-only queries in analytical workloads, query doesn’t have to be restarted if a case of one node’s query fails.In cloud there is a high failure rate. It can happen in single node failure during long query processing. †¢ Ability to run in a heterogeneous environment Due to hardware failures in the system nodes in cloud not act as homogeneous. When the work is equally divided among all nodes, time takes to complete the task should be equal to time that needed slowest node needed to complete its portion of work.

Fog computing can also be called as edge computing, is a distributed computing infrastructure in nature, for smart devices like mobile phones the application services should be maintained near the end user side but the services are handled at remote data server i.e. in cloud. Our aim is to reduce the amount of storage required, the time required in data processing and data analysis and the propagation time in cloud computing. Thus by handling data at networkRead MoreAndroid Lab Report1472 Words   |  6 Pages5.2. Residual Artifacts on Android Devices In these experiments, we performed a series of read, upload, and download operations on the sample data-set. The important parts and files of each browser are listed in Table-3. The investigation of each operation on each experimental VM is exposed in the later tables. This experiment found that the majority of artifacts are stored in database files of the storage layer of Android.
