Cloud Computing Models and Concepts

A technology that creates virtual computing environments that simulate the functionality of physical systems using the resources of a host machine. It allows one host machine to run multiple, independent instances of virtual machines (VMs).

Virtual machines (VMs) are essentially software-based representations of physical computers that can run their own operating systems and applications. They can be thought of as 'guest systems' running within a 'host machine'.

A type of virtualization that allows users to run multiple operating systems (OS) within one physical machine, each in its own separate virtual environment. This enables users to access various OS without physically installing them on their devices.

A central server hosts numerous virtual machines that are then delivered to users based on their specific needs. This provides users with the flexibility to access any desired OS without the hassle of physical installation.

This type of desktop virtualization involves using hypervisor software directly on a local system to run multiple OS simultaneously without affecting the host operating system. This allows users to work with multiple OS on their own device without needing a separate virtual machine.

A software layer that enables virtualization by providing an interface between the physical hardware and the virtual machines. It manages resource sharing, security, and other aspects of virtualization.

Virtualization technology that combines multiple physical networks into a single virtual, software-defined network. This simplifies network management, allows for efficient resource allocation, and increases network flexibility.

Type of network virtualization that virtualizes the hardware controlling network traffic routing. This offers greater flexibility, automation, and centralized control over the network infrastructure.

A service model where the provider manages and delivers hardware and software resources for developing, testing, and managing cloud applications. You gain access to a ready-to-use platform for building software products.

A service model where the provider manages and maintains a full application stack that customers can access and use. You don't need to manage IT equipment.

A cloud provider that offers services to the general public over the internet. Examples include AWS, Azure and Google Cloud.

A cloud provider that operates exclusively for a single organization or third party. It can be on or off premise.

A hypervisor that directly interacts with the hardware and manages virtual machines (VMs) without an operating system (OS) in between.

A hypervisor that runs as an application on top of an existing operating system (OS) and then manages VMs.

A combination of public and private cloud services. Organizations might use a public cloud for non-sensitive data and a private cloud for sensitive data.

Providing access to computing resources over the internet, like servers, storage, and software, on a pay-as-you-go basis.

A cloud deployment model where resources are shared amongst multiple organizations. It offers lower costs and scalability.

A cloud deployment model where resources are owned and managed by a single organization. It offers more control and security.

A type of virtualization that creates a virtual environment that simulates the functionality of a physical system using the resources of a host machine. This allows multiple independent instances of a virtual machine (VM) to run on one physical machine.

A type of application virtualization that allows software to run on a remote server, with users accessing them via a remote control protocol. This requires a constant network connection for use.

A type of application virtualization that allows software to run on the user's device but within a separate virtual environment. This allows the software to run without affecting the host OS.

A type of network virtualization that combines multiple physical networks into one virtual network. This simplifies network management and allows for efficient resource allocation.

A cloud computing deployment model that combines aspects of both public and private clouds. It allows flexibility and customization for specific needs while also offering lower costs.

A cloud service model where the provider manages and delivers hardware and software resources for developing, testing, and managing cloud applications. This allows your business to build software products without managing the underlying infrastructure.

A cloud service model where the provider owns and operates the infrastructure, but customers manage and purchase software. This gives businesses flexibility to customize their infrastructure and applications.

A cloud service model where the provider manages and maintains a full application stack that customers can access and use. It's like renting out software instead of installing it locally.

Cloud service providers such as AWS, Azure, and Google Cloud that offer services to the general public over the Internet. They make cloud computing accessible to everyone.

Cloud service providers operated exclusively by a single organization or third party. They offer more control and security.
