What is Cloud Computing?

 

Moving to the cloud. Running in the clouds. Stored in the clouds. Reached from the cloud: these days it seems like everything is happening "in the cloud". But what exactly is this absurd idea?

The short answer is that somewhere at the end of your internet connection there is a place where you can access applications and services, and where your data can be stored securely.

Cloud computing is much-needed access to computer programming resources, especially for data storage and computing capabilities, without any direct user-friendly management. Large clouds often have tasks spread across multiple locations, each location being a data center.

Types of cloud computing

The cloud deployment models are private, public, or hybrid.

1. Private Cloud

This model has infrastructure owned by one business. This model can be held indoors or handled outdoors. Although expensive, the private cloud model is ideal for large organizations that focus on...

• The highest level of security
• Better autonomy over servers
• Very customizable
• There is no risk of sudden changes that could disrupt the company's operations
• Evil private cloud:

It requires extensive technology for IT staff

It is relatively expensive

2. Public Cloud

This model has services and infrastructure shared by all organizations. With the large space available, distribution becomes easier on social cloud solutions. Organizations pay public cloud models for each payment, making it an ideal solution for small businesses looking to save money.

• Very scalable
• Inexpensive
• Management transferred to the cloud service provider
• Not bound by local restrictions
• Community Cloud Buyer:
• Provides fewer wishes
• Sudden changes in the cloud provider can have serious consequences
• Less autonomy over servers
• As the server is shared, it is less secure

3. Hybrid Cloud

A combination of public and private clouds, the integrated cloud combines two models to create an integrated solution that allows both platforms to interact freely.

• Very safe, flexible, and economical
• Better security than pure public cloud solutions
• Combined cloud buyer:

How does cloud computing work?

Cloud computing works by allowing client devices to access data over the Internet, from remote servers to information and from a computer.

An Internet connection connects to the front end (including the client access device, browser, network and software) with the back end, which contains data, servers, and computers). The back end serves as a repository, storing pre-accessed data.

The connection between the front and back edges is controlled by the central server. The central server depends on agreements to facilitating data exchange. The central server uses software and middleware to manage the connections between different client devices and cloud servers. Normally, there will be a dedicated server for each program.

Examples of Cloud computing

Dropbox, Facebook, Gmail.
