What is cloud computing? Everythings that you need know about cloud computing

What is Cloud Computing?

Cloud computing is Internet-based  cloud computing, which provides shared resources, software and information on computers and other devices on demand, such as a power grid

The idea behind cloud computing is similar Users can easily access storage, computing power, or specially designed development environments without worrying internally about these tasks. Cloud computing is usually Internet-based computing 

Cloud computing is a common concept that uses a software as a service (saas), such as Web 2.0 and other technical trends, all of which depend on the Internet to meet the needs of users. For example, Google Apps provides general business applications online that are accessed from a web browser, while software and data are stored on the Internet server.

Third-party cloud computers enable organizations to focus on their core businesses rather than expending resources on infrastructure and maintenance. Lawyers note that cloud computing allows companies to avoid or minimize IT infrastructure cost.

Cloud computing often uses grid computing, it has autonomous features and is billed like utilities, but cloud computing can be seen as a natural next step from the grid-utility model. Some successful cloud architectures have little or no centralized infrastructure or billing systems, including peer-to-peer networks such as BitTorrent and Skype. 

We can also add:

Virtualization (Private Cloud Computing), which is capable of running a self-contained application on a cloud computer (which includes a complete virtual infrastructure including file system, database, mini OS, an application program, etc.)

Cloud computing in E-Learning

    Use of tools to share links and artwork along with social software like blogs and website.
    Online learning management system services use

Cloud computing in a personal learning environment

Some similar tools like class social software
A related use case is a personal research and learning environments, i.e. the personalized combination of local and web services for both research and teaching

Common Cloud Computing Services Models

1. Software (SaaS) as a service

SaaS is a software distribution method that provides access to software and its functions remotely as a web-based service. Instead of paying the advance fee for the purchase or licensing software, the mother-in-law prepares a recurring fee to subscribe to the customer service.

2. As a service platform (PaaS)

Paas is a computing platform distributed as a service. Here the platform has been outsourced in place of the company or data center and instead of managing its hardware and software layers. Most Pages are designed for developers and want to simplify the process of creating and deploying the software. For example, a web developer can use a dice that includes operating system software, web server software, database, and related web development tools. Major pass vendors include Amazon Web Services, Microsoft Azure, IBM and Google Cloud Platform.

3. Infrastructure as a service (IAAS)

Computer infrastructure, such as servers, storage, and networking distributed as a service. IAAS is popular with enterprises who appreciate the convenience of cloud vendors to manage their IT infrastructure. They sometimes see cost savings as a result of paying computing resources. Leading IAAS vendors include Amazon Web Services, Microsoft Azure, IBM and Google Cloud Platform.

While SAAS, PASS, and IAAS are the three most common types of cloud services, cloud computing vendors sometimes use the label as "service" to describe other offerings.
