 CLOUD COMPUTING TECHNOLOGIES

Certain technologies are at work behind the scenes of cloud computing platforms, making them m adaptable, dependable, and useful. The following technologies are listed:

  • Virtualization,
  • Service-Oriented Architecture (SOA)
  • Grid Computing
  • Utility Computing

Virtualization

Virtualization is a method that allows several organizations to share a single physical instance of an application or resource. It accomplishes this by giving a physical resource a logical name and delivering a reference to that physical resource when needed. Details of virtualization are discussed in Unit IV.

Service-Oriented Architecture

Regardless of the manufacturer, product, or technology, Service-Oriented Architecture enables the usage of applications as a service for other applications. As a result, data may be exchanged across apps from various manufacturers without the need for further programming or service modifications. The graphic below depicts the cloud computing service-oriented architecture.



Grid computing

Grid computing is a type of distributed computing in which several computers from various places collaborate to achieve a shared goal. These computing resources are diverse and distributed around the globe. Grid computing divides large tasks into smaller chunks that are dispersed across the grid's CPUs.



Utility Computing

Utility computing is a service delivery paradigm in which a service provider makes computing resources and infrastructure management available to customers on an as-needed basis and charges them based on consumption rather than a fixed cost. The utility model, like other kinds of on-demand computing, attempts to optimize resource efficiency and/or decrease related costs. The Pay-per-Use concept is used in utility computing. As a metered service, it provides computing resources on demand. Utility computing is the foundation of cloud computing, grid computing, and managed IT services.

Cloud Computing Technologies

The different innovations of cloud computing are listed below:

1. Virtualization

It is the process of sharing license keys to physical instances of applications among different users of the enterprise. The main purpose of this technology is to provide a standard version of the cloud application to all clients. It is popularly used for its flexibility and instant running process. Few types of virtualization are

Hardware Virtualization: If the virtual machine is directly installed on hardware servers, it is called Hardware virtualization because it is easier to control a Virtual Machine than a physical server.

Operating System Virtualization: If the virtual machine is installed in a guest server instead of the hardware system, it is called Operating system Virtualization. It increased the testing situation of various software on various OS platforms,

Server Virtualization: If the virtual machine is installed on the system, it is called Server Virtualization. It is divided into multiple resources and utilized for load balancing on-demand basis.

Storage Virtualization: The process of collecting physical storage from different network storage devices is called Storage Virtualization. It is mainly used for backup and recovery.

2. Service-Oriented Architecture

SOA is an application that divides the services into individual business functions and procedures daily. This unique component of cloud application enables cloud-related arrangements that can be modified and adjusted on request as business needs. Service-oriented system diffuses two major components, one is Quality as service and other software as service. The function of Quality of service is to identify the function and behavior of a service from a different view. Software as a service provides a new delivery model of software which is inherited from the world of application service providers

3. Grid Computing

This is a process of connecting multiple servers from multiple to achieve a common goal. Grid computing turns large problems into smaller ones and broadcasts to servers and places them within the grid. It is mainly applied in e-commerce and is intended to share the resources on huge-scale cluster computing. A popular grid computing project is Folding@home. The project aims to find protein folding, misfolding and related diseases. It involves utilizing the power of unused computers and solving complex scientific problems

4. Utility Computing

This process relies on the pay-per-utilize model. It gives computational services on demand for a metered benefit. It mainly helps in cost-cutting by reducing initial investment. As the computing requirements for a business change, the billing also changes accordingly, without acquiring any additional cost. If the client usage has decreased, then billing cost also reduces accordingly.

Explain Parallel Efficiency of MapReduce.

 PARALLEL EFFICIENCY OF MAP-REDUCE It is worth trying to figure out what is the parallel efficiency of MapReduce. Now let us assume that the data produced after the map phase is σ times the original data size D (σD), further, we assume that there are P processors which in turn perform map and reduce operations depending on which phase they are used in, so we do not have any wastage of processors. Also, the algorithm itself is assumed to do wD useful work, w is not necessarily a constant it could be D^2 or something like that, but the point is that there is some amount of useful work being done even if you have a single processor and that's wD. Now let us look at the overheads of doing the computation wD using MapReduce. After the map operation, instead of D data items, we have σD data items in P pieces, so each mapper writes data to their local disk. So, P there is some overhead associated with writing this data. Next, this data has to be read by each reducer before it can begin ...

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?

  b) The specific OLAP operations to be performed are: 1. Roll-up on date from date id to year. 2. Roll-up on spectator from spectator id to status. 3. Roll-up on location from location id to location name. 4. Roll-up on the game from game id to all. 5. Dice with status= “students”, location name= “GM Place”, and year=2004

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.
