Explain architecture of the Aneka-based computing cloud in detail.

 The architecture of the Aneka-based computing cloud 

  • The Aneka-based computing cloud is a collection of physical and virtualized resources that are linked via a network, which can be the Internet or a private intranet. Each of these resources contains an instance of the Aneka Container, which represents the runtime environment in which the distributed apps operate. The container offers the fundamental management features of a single node and leverages all other activities on the services that it hosts. The services are divided into three categories: fabric, foundation, and execution. Fabric services provide hardware profiling and dynamic resource provisioning by interacting directly with the node via the Platform Abstraction Layer (PAL). The fundamental system of the Aneka middleware is identified by foundation services, which provide a collection of fundamental capabilities that allow Aneka containers to conduct specialized sets of jobs. Execution services deal directly with the scheduling and execution of Cloud applications.



  • Aneka's ability to provide alternative methods of expressing distributed applications by delivering alternative programming models is one of its primary advantages; execution services are largely concerned with supplying the middleware with an implementation for these models. Additional services, such as persistence and security, are cross-cutting throughout the full stack of services hosted by the Container. At the application level, a variety of components and tools are given to 1) ease application development (SDK); 2) move existing apps to the Cloud; and 3) monitor and manage the Aneka Cloud. 
  • Aneka's most typical deployment is shown in the figure. An Aneka-based Cloud is made up of a collection of networked resources that may be dynamically adjusted to meet the demands of the user through resource virtualization or by utilizing the spare CPU cycles of desktop PCs. If the deployment designates a private Cloud, all resources, for example, are in-house, such as within the organization. This deployment is expanded by adding on-demand publicly accessible resources or by interfacing with other Aneka public clouds that provide computing resources connected over the Internet.

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

Describe how cloud computing technology can be applied to support remote ECG monitoring.

  Healthcare: ECG (Electrocardiogram) Analysis in cloud computing Healthcare is a field, subject, sector, or territory in which information technology has several uses. These apps are being used to aid businesses in supporting scientists in developing disease prevention solutions. Cloud computing has emerged as an appealing alternative for constructing health monitoring systems as a result of the development of the Internet or to put it another way, as a result of the availability of the internet. The ECG machine, for example, is a health monitoring device that measures the human body's heartbeat and prints the results on graph paper. The electrocardiogram (ECG) measures the electrical activity of the heart's Cardium. A waveform is created as a result of this action, which is repeated throughout time and symbolizes the heartbeat.  The analysis of the shape is used to identify arrhythmias, and it is the most common way of detecting heart diseases. Here the meaning of arrhythmias
