Cloud Computing:

😊 Cloud computing is a way of providing shared computing resources. These resources include applications, computing, storage, networking, development and deployment platforms as well as business processes. By providing standardization and automation, cloud computing makes computing resources easier to use.😊


Types of vitrualization pertaining with case study:

👉Application Virtualization:

Application virtualization hosts individual applications in which a virtual environment is entirely separate from the underlying operating system (OS).

Application virtualization makes it possible to encapsulate all the elements of any particular application and run them independently from the underlying OS.

It means that the machine that is running the application does not have that application installed. It resides on a (virtual machine) VM in a remotely located server.

Some of the top platforms that specialize in application virtualization software are:

  • Citrix Virtual Apps and Desktops
  • Microsoft App-V
  • Parallels Remote Application Server (RAS)

👉Data Virtualization:

Data virtualization is a data management approach. It retrieves, segregates, manipulates, and delivers data without any data specifications.

Any technical details of the data like its exact location and formatting information are not needed to access it. It allows the application to get a singular view of the overall data with real-time access.

Data virtualization software helps with data warehouse management and eliminates latency. It also provides users with on-demand integration, quick analysis, and real-time search and reports capabilities.

Three of the top data virtualization software are:

  • Denodo
  • JBoss Data Virtualization
  • TIBCO Data Virtualization

👉Desktop Virtualization:

The desktop Virtualization approach is also known as a client-server computing model. It stores any desktop environment virtually on a centralized remote server.

Desktop virtualization software helps with workstation load and offers; smooth employee onboarding, redundant process removal, disaster recovery, single interface customization, and more.

Top desktop virtualization software platforms include:

  • Amazon Work Spaces
  • Citrix Xen Desktop
  • VMware Workstation and VMware Fusion

👉Network Virtualization

In network virtualization, all physical networking tools and other resources are integrated into one software-based resource. It further breaks the bandwidth into multiple channels, independent of one another.

A network virtualization software creates a tunnel through the existing network. This way, the admins can run VMs without the need for individual network reconfiguration.

The bandwidth division thus allows users to assign the channels to multiple systems in real-time. Three of the best network virtualization tools include:

  • 6WIND Virtual Accelerator
  • Cisco Nexus Virtual Services Appliance
  • JunosV App Engine

👉Server Virtualization

Server Virtualization, also known as hardware-based virtualization, divides a physical server into multiple virtual servers that run guest operating systems independently.

Server virtualization software reduces the need for multiple physical servers and requires a lesser amount of hardware. Thus, it’s a highly effective cost reduction technology.

The top three server virtualization platforms include:

  • IBM PowerVM
  • Nutanix AOS
  • Proxmox VE

👉Storage Virtualization:

Storage virtualization performs resource abstraction in a way that the multiple physical storage arrays are virtualized as a single storage pool with direct and independent access.

The storage virtualization software aggregates and manages storage in various storage arrays and serves it to applications whenever needed.

The centralized virtual storage increases flexibility and availability of resources needed. This data virtualization and centralization is easily manageable from a central console. It allows users to manage and access multiple arrays as a single storage unit.

Top storage virtualization platforms include:

  • FalconStor Network Storage Server
  • IBM Storage Virtualization
  • QUADStor Systems

Creation of application load balancer for VPC the pre-requisites that are required for this application load balancer are An AWS account https://aws.amazon.com/console/ Now let us look into the steps required for creating a application load balancer: First in order to create a load balancer we need a VPC with different subnets associated with different regions so go ahead and first create a VPC first with following configurations. 2. Now I am going to create four subnets where I use each of two subnets as private and public respectively with different regions for each of them in private and public respectively go to subnets section in your AWS console and click on create subnet enter the configurations as given in the below                                                  Similarly create two other subnets with different regions and Ip addresses. 3. Now we have to create IGW (Internet gateway) and add them as a route in route table of public subnets in order to provide access to any IP
