Cloud computing is a mutual word for anything that offers hosted services over the Internet. These services fall into three main categories: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).
Cloud infrastructure includes the hardware and software components required to implement a cloud computing model successfully. Cloud computing can also be viewed as service computing or on-demand computing. The name cloud computing is inspired by the cloud symbol often used to represent the Internet in diagrams and flowcharts.
How does Cloud Computing Work?
Cloud computing allows client devices to access data over the Internet, from servers, databases, and remote computers. A connection to the Internet system connects the front end (access to the client device, browser, network, and also cloud software application) with the back end, which consists of databases, servers, and computers. The rear end is a repository that stores the data accessed by the front end.
Therefore, a central server manages the communication between the front and back end. The central server is built on protocols to facilitate data exchange. The central server uses software and middleware to manage the connectivity between the various client devices and the servers in the cloud. Usually, there is one active server for each application.
Examples of Cloud Computing
Here are some examples of cloud computing:
Google Docs, Microsoft Office 365
Operators can contact Google Docs and Microsoft Office 365 over the Internet. As a result, users can be more innovative because they can access workloads and spreadsheets stored in the cloud anytime and from any device.
Email, Calendar, Skype, and WhatsApp
Email, Calendar, Skype, and WhatsApp leverage the ability of the cloud to give users remote access to data, allowing them to access their data anytime and from any device. And where you want.
Zoom is cloud-based video conferencing and audio software that records and also stores meetings in the cloud for users to access anytime, anywhere.
Lambda allows developers to run code for core applications or services without having to provision or manage servers. And the pay-as-you-go model also evolves periodically with a pool to account for real-time data usage and storage changes.
Cloud Computing Vs. Traditional Web Hosting
A cloud service has three different appearances that distinguish it from previous web hosting:
- Users can access massive amounts of computing power when needed. It is usually sold by the minute or hour.
- It’s elastic users can have as much or as little service as they want at any time.
- The provider manages the entire service (the consumer only needs a PC and internet access). Important innovations in virtualization and spread computing, as well as improved broadband Internet access, have accelerated interest in cloud computing.
Benefits of Cloud Computing
Cloud computing offers several attractive benefits for businesses and ends users. Some of the main advantages of cloud computing are.
A cloud structure can reduce costs because companies do not spend large sums of money on purchasing and maintaining equipment. It reduces your capital expenditure because you don’t have to invest in hardware, facilities, utilities, or large data centers to accommodate your business growth. In addition, firms do not want large IT teams managing cloud data center operations. Because they can faith the expertise of their cloud provider teams. Cloud computing also reduces costs associated with downtime. Because downtime is rare with cloud computing, businesses don’t have to spend time and money troubleshooting downtime.
Uploading information to the cloud means users can access it from anywhere using any device with just an internet connection. Users do not need to carry around USB drives, an external hard drive, or multiple CDs to access their data. Users can also access company data from smartphones and other mobile devices, allowing remote employees to stay connected with colleagues and customers. In addition, end users can quickly process, store, retrieve and recover resources in the cloud. Cloud providers automatically deploy all upgrades and updates, saving you time and effort.
All organizations worry about data loss. Cloud data storage confirms that users can always access their data, even if their devices, such as laptops or smartphones, are not working. Businesses can quickly recover their data in emergencies like natural disasters or power outages using cloud-based services.
Cloud computing is the provision of computer system resources, particularly data storage and computing power, without direct active management by the user. Large clouds often have functions spread across multiple sites, each being a data center.
