What is Cloud computing?
Simply it is to access various services and data over the Internet, without the need to buy or set up data centers or servers. That is, they allow you to rent technology and servers or servers instead of buying them. It also allows you to store your data and information online instead of having it on hard drives or local storage devices and servers. These cloud services include many services, such as: data storage, servers, databases, networks, and programs. Access it online from anywhere, from any device, quickly, efficiently, securely and at a lower cost. Simply, cloud computing is the use of the Internet and cloud servers to store and host data rather than physical hardware. And rent these servers and their technology without having to buy them.Who uses cloud computing services?
We can say that everyone uses cloud computing and not just companies. Your mobile phone, smartwatch, email, and other apps use the cloud to store their data. As long as your device is connected to the Internet, you can use cloud services and recall this data. Cloud storage usage increases for individuals who need more storage space for their business and data. But businesses remain the biggest beneficiaries of cloud services. The cloud saves costs, speeds up enterprise performance, and increases efficiency and security. Most important is the ability to recover from technological disasters by keeping a copy of the data in the cloud away from devices that could malfunction.How does cloud computing work?
Cloud computing takes place in 3 basic steps or processes: Cloud providers store data and applications on huge servers and devices in locations known as data centers. By subscribing to cloud services, subscribers can access and use these servers online. Service Providers make any repairs, updates, or upgrades that require the continuation and upgrade of the Service. Thus, companies and institutions devote themselves to serving their customers and developing their services better, instead of worrying about data storage, management, server maintenance, etc. This work is assigned to cloud computing service providers, who in turn handle all technical logistics. Cloud providers handle technical things such as: purchasing the necessary software licenses, upgrading and updating servers, purchasing more hardware for more space. Doing whatever it takes to provide, secure, maintain, upgrade and continuously update a robust technical infrastructure.Advantages of cloud computing
- You can use software and applications or extract data from any device connected to the Internet. Giving work more flexibility and productivity. And you can transfer, modify, develop, upgrade and update them in a fast and secure way.
- You can scan your email and store files using cloud services like Dropbox and Google Drive.
- With cloud computing services you can also stream music and videos online. keep additional copies in the cloud and avoid losing them if a hardware failure occurs.

- Encryption and security measures protect data greatly but it is also still vulnerable to hacking by hackers and fraudsters.
- Technical problems may occur from employees and managers of the cloud system leading to technological disasters.
