1.) Network virtualization: It is a process of logically grouping physical networks and making them operate as single or multiple independent networks called Virtual Networks. Work flow:   Example: ->Network virtualization may be used in the development of application testing to mimic real-world hardware and system software. ->It helps us to integrate several physical networks into a single network or separate single physical networks into multiple analytical networks. ->In the field of application performance engineering, network virtualization allows the simulation of connections between applications, services, dependencies, and end-users for software testing. ->It helps us to deploy applications in a quicker time frame, thereby supporting a faster go-to-market. ->Network virtualization helps the software testing teams to derive actual results with expected instances and congestion issues in a networked environment.

1.) A.)AWS as a public: ->Data storage ->Data Archival >Application Hosting- >Latency intolerant or mission critical web tiers ->On-demand hosting for microsite and application ->Auto-scaling environment for large applications B.) AWS as a private: ->Strict security, latency, regulatory and data privacy levels not met by the public cloud. ->Organizations that are highly regulated and need data hosted privately and securely. ->Organizations that are large enough to support the costs. ->Organizations that need high-performance access to a file system, such as media companies. ->Hosting applications that have predictable usage patterns and demand low storage costs. ->Organizations that demand greater adaptability, configurability, and flexibility. ->Hosting business-critical data and applications. 2.)Features of an Ec2 machine: ->Virtual computing environments, known as instances ->Preconfigured templates for your instances, known as Amazon Mac

  1. Download  Disk2VHD  from Microsoft and open it. Create a partition and store a file in it.  Select the partition to migrate. 2. Now convert the vhdx file to vdi using the following command. ` VBoxManage clonehd "{fileLocation}\{fileName}.{vhd\vhdx}" {fileLocation}.vdi --format vdi ` 3. From virtul box now select the storage for the vm and run with it. 4. Now you can access the contents of the virtual hard drive.

 Cloud Computing: Cloud computing is the delivery of computing services which includs  servers, storage, databases, networking, software, analytics, and intelligence over the Internet. Types of virtualization: 1.) Server Virtualization  ->The physical servers are powerful machines with multiple processors that host files and applications on a computer network.  ->For streamlining purposes each physical server is typically dedicated to the one of the specific application or task.  ->However, this can become inefficient because each server will only be using a fraction of its available processing resources. ->It also deals with this problem by allowing an administrator to convert a server into multiple virtual machines. 2.) Application Virtualization ->While traditionally running an application uses your existing operating system and its hardware resources. ->Essentially, you are running the application on top of your computer. Application virtualization encapsulates th
