  VIRTUALIZATION

  • The formation of a virtual version of something, such as a server, a desktop, a storage device, an operating system, or network resources is referred to as virtualization. 
  • Virtualization is a technology that allows numerous consumers and organizations to share a single physical instance of a resource or accomplishes this by giving a logical name to a physical storage device and delivering a reference to the physical resource when needed. 
  •  Virtualization is a concept that is utilized in practically every IT architecture to assist double the capacity of physical devices. It aids in making the most use of current resources, lowering total corporate c costs Virtualization software (hypervisor) is used by businesses to construct virtual computers, network desktops, and servers.
  • Virtualization software simplifies IT management and makes it more cost effective to buy and run. It brings about a variety of favorable changes, such as lower hardware costs, improved disaster recovery solutions, higher IT agility, improved performance, and faster resource availability. Understanding the various forms of virtualization is essential for integrating it. Businesses can select the sort of virtualization they needed based on their needs.


Benefits of Virtualization

1. It is cheaper: 

Because virtualization does not need the usage or installation of physical hardware components, IT infrastructures find it to be a less expensive technology to employ. There is longer a need to allocate significant amounts of space and substantial sums of money to build on-site resources. You just buy the license or access it from a third-party source and start working if the gear were installed locally.

2. It keeps costs predictable: 

Individuals and corporations can have predictable costs for information technology needs because third-party providers typically provide virtualization options. 

3. It reduces the workload :

The majority of virtualization service providers immediately update the
hardware and software that will be used. The third-party vendor installs these upgrades instead of
sending individuals to perform them locally. This allows local IT specialists to focus on other responsibilities and saves even more money for individuals or organizations. 

4. It offers a better uptime: 

Thanks to virtualization technology as uptime has increased considerably. Some service providers guarantee a 99.9999% uptime. Even low-cost companies now guarantee 99.99% uptime.

5. It allows for faster deployment of resources:

When virtualization is implemented, resource provisioning is quick and easy. There is no longer a requirement to establish physical machines local networks, or other information technology components. It may be propagated throughout the rest of the company as long as there is at least one point of entry to the virtual environment.

6. It promotes digital entrepreneurship: 

Before the widespread adoption of virtualization, digital entrepreneurship was virtually impossible for the average person. Almost anybody can start their side hustle or become a company owner today, thanks to the many platforms, servers, and storage devices that are accessible.

7. It provides energy savings: 

Virtualization is an energy-efficient technology for the vast majority of consumers and businesses. Energy consumption rates can be reduced because no local hardware or software alternatives are used. Instead of paying for data center cooling and equipment operating costs, monies can be repurposed for other operational expenses over time to increase virtualization's total ROI.

8. Easier backup and disaster recovery :

You may do backups and snapshots of your virtual machines in addition to complete backups of your virtual server. These virtual computers may be easily and quickly relocated from one server to another. Throughout the day, snapshots may be collected resulting in significantly more up-to-date data. Furthermore, because launching a snapshot is faster than running a conventional server, downtime is drastically reduced. Disasters strike quickly and unexpectedly. Leaks, floods, power outages, cyber-attacks, robberies, and even snowstorms all wipe away critical data in seconds. Virtualization allows for considerably faster and more accurate recovery with less labor and a fraction of the equipment - it is all virtual.

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?

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage virtualization is a system administration practice that allo
