Virtualization

is the process of creating a virtual version of a physical resource, such as a computer, server, storage device, or network

Hypervisor

virtualization uses software (called _) to allow one physical machine to run multiple virtual machines (VMs), each with its own operating system and applications.

One computer, many systems

A single physical machine can run multiple operating systems at the same time (e.g., Windows + Linux).

Isolation

Each VM is independent, so if one crashes, it doesn’t affect the others.

Efficiency

Makes better use of hardware resources.

Flexibility

Useful for testing, learning, and running apps that need different OS environments.

Key points of virtualization (OIEF)

Hypervisor

It acts as a manager between the physical hardware (host) and the virtual machines (guests). The_ allocates CPU, memory, storage, and other resources so that multiple VMs can run independently on one physical machine.

VirtualBox

is a free and open-source virtualization software developed by Oracle that allows you to create and run multiple virtual machines (VMs) on a single physical computer.

Intel VT-x

Requirement for intel processor

AMD-V

Requirement for amd processor

Virtual Disk Images

This is where the OS will be installed. At least 25-50 GB of free space per virtual machine.

Ubuntu, Fedora, Debian

Types of linux

Guest OS ISO File

An ISO file is a disk image—a digital copy of an installation CD or DVD. You will need the ISO file for the operating system you want to install inside your virtual machine

Guest Additions

are software packages installed inside the VM that improve integration with the host system.

Virtual machines

can be started or stopped using the virtualization software interface or cloud portal.

Snapshots

capture the entire state of a VM at a particular moment in time. This includes the contents of the memory, settings, and disk state.

Shared Folders & Clipboard

Virtual machines often support shared folders to exchange files easily between the host and guest operating systems.

Basic Usage of Virtual Machines (SISS)

VirtualBox is free to download, Cross-platform, support multiple guest os, snapshot feature, simple to use, good for testing

Advantages of Using VirtualBox (VCSSSG)

Common use cases

refer to practical, real-world situations where virtualization is applied to solve a problem or achieve a goal.

Education and Training, Software and Development, Ethical Hacking Practice, Business IT and legacy applications, Everyday users and travelers

Common Use Cases of Virtualization (ESEBE)

Platform integration

The process of connecting different software systems, applications, and data sources to enable seamless communication, data exchange, and automation.

Interoperability

Refers to the standards, protocols, technologies, and mechanisms that allow data to flow between diverse systems with minimal human intervention

Integration

connection.

Interoperability

communication.

Improved efficiency and productivity, centralized and accurate data, scalability and flexibility, cost reduction, enhanced security and compliance

Benefits of platform integration (ICSCE)

API, Middleware

Common methods of Integration (AM)

API (application programming interface)

is a set of rules and protocols that allows applications to talk to each other.

Middlewares

are a layer of software that sits between two or more applications, databases, or systems, acting as a “translator” or “broker”.

Application Middleware

type of middleware is used within a specific application to handle tasks like parsing data or managing sessions.

iPaaS (Integration Platform as a Service

a cloud-based solution that allows you to integrate different applications and services without writing code.

Technical Interoperability

Refers to the basic ability of systems to connect and exchange data through compatible hardware, software, or communication protocols.

Semantic Interoperability

Ensures that the meaning of exchanged data is understood the same way by all systems.

Organizational Interoperability

Focuses on how people, processes, and institutions coordinate and work together when systems exchange information.

Technical,Semantic,Organizational

Types of Interoperability (TSO)

Data Privacy, Security, Compatibility, Cost, Complexity

CHALLENGES IN INTEGRATION AND INTEROPERABILITY (DSCCC)

Cloud-based Integration, API-Driven Integration, Low code / no tools

Current Trends in Platform Integration (CAL)

Low-code and no-code tools

are designed for people who don’t have programming or coding knowledge

Ai-powered integration, hyper automation, enhance security and compliance

Future trends in platform technology (AHE)

Bare-Metal Hypervisor, Hosted Hypervisor

Types of Hypervisor (BH)

Bare-Metal Hypervisor

Runs directly on the computer’s hardware. TYPE 1

Hosted Hypervisor

Runs on top of an existing OS TYPE 2
