Cloud computing is a model for delivering on-demand computing services — from applications to data centers — over the Internet. This means that instead of running software and storing your data on your own computer, you can access everything you need through the cloud.

Cloud computing offers several advantages, including cost savings, increased flexibility, scalability, accessibility, and security. By using shared resources, companies can reduce their infrastructure costs. Cloud services also offer greater flexibility, allowing businesses to scale their computing power up or down as needed.

LAN (Local Area Network) is a network that connects devices in a limited geographical area, such as a home or office. It is typically owned and managed by the organization that uses it. Cloud computing, on the other hand, is a network of data centers that provide computing services over the internet. The cloud provider owns and manages the infrastructure.

There are four main types of cloud computing deployments: public cloud, private cloud, hybrid cloud, and community cloud. Public cloud is shared by many organizations, while private cloud is for exclusive use by a single organization. Hybrid cloud combines both public and private cloud, offering flexibility and security. Community cloud is shared by a group of organizations with common interests.

A model for delivering computing services - servers, storage, databases, networking, software, analytics, intelligence - over the internet ('the cloud'). It offers on-demand access to resources, pay-as-you-go pricing, and scalability.

A distributed computing environment that connects multiple computers to share resources and achieve high performance. It often utilizes idle resources from various locations.

A model where computing resources are provided as a utility, similar to electricity or gas. Users pay for what they use, like a pay-per-use service.

A cloud computing service that is available to the general public, with resources shared among multiple organizations and users. Examples include Amazon Web Services (AWS) and Google Cloud.

A cloud computing service that is dedicated to a single organization. Resources are not shared with other organizations.

A cloud computing environment that combines public and private clouds, allowing organizations to leverage the benefits of both.

A cloud computing model where users rent access to basic computing resources like servers, storage, and networking. The user manages the operating system and applications.

A cloud computing model where users rent access to a platform for developing and running applications. The vendor manages the infrastructure and operating system.

A cloud computing model where users subscribe to access software applications over the internet. The vendor manages the entire infrastructure, operating system, and applications.

Cloud computing provides advantages like improved flexibility, scalability, cost reduction, and access to information anywhere, any time.

Cloud computing addresses challenges faced by modern IT departments, such as high infrastructure costs, limited scalability, and difficulty managing complex systems.

There are four types of cloud deployments: public, private, hybrid, and community. Public clouds are shared, private are exclusive, hybrid combines both, and community is shared by a group with common interests.

The three main cloud service models are IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service), and SaaS (Software-as-a-Service). Each model offers different levels of control and management responsibilities.

Cloud computing offers several benefits, including cost savings, increased flexibility, improved scalability, enhanced security, and global accessibility.

Cloud computing provides on-demand self-service, utilizes broad network access, pools computing resources, and often runs on virtualized servers.

Grid computing connects multiple computers to share resources, enabling organizations to utilize resources efficiently, provide fault tolerance, and easily scale up or down.

Cloud computing encompasses the characteristics of grid computing, utilizing distributed resources for increased efficiency, fault tolerance, and scalability.

Cloud computing shares similarities with utility computing, where resources are provided as a service and users pay for what they consume.

Public cloud is shared among multiple organizations, private cloud is dedicated to a single organization, hybrid cloud combines both, and vertical clouds cater to specific industries.

IaaS provides users with access to basic computing resources like servers, storage, and networking. The user manages the operating system and applications.

PaaS allows users to develop and run applications on a cloud platform, without managing the underlying hardware and software.

SaaS provides users with access to software applications over the internet. The vendor manages the entire infrastructure, operating system, and applications.

Cloud computing offers cost savings, increased flexibility, scalability, accessibility, and security, making it beneficial for individuals and organizations.

Concerns related to legacy IT systems, reliability, privacy, security, regulatory environment, and criminal use of cloud computing services exist.
