For less technical users there is always a lot of confusion between different terms used in modern tech and cyber world, those terms look like Chinese for many people and they often mistake one term with another. One of such terms is VPN and Cloud Computing. While they don’t look similar, if you know the basic meaning of each term, you may think they are used for similar needs and are quite the same, but that’s not true.
If we explore each of them separately, explain their deep meaning and typical usages, it is clear that these two are actually different pieces of technology, used by different kinds of users, for different needs. First of all, let’s start with a VPN.
What is a VPN, why it is needed and who use it?
VPN is the abbreviature and stands for Virtual Private Network, a small network which connects a small list of devices with the internet, in a secure way. VPN does the nearly the same job as your Internet Service Provider, but there are some differences, the main difference is that a VPN is way more secure than ISP.
On a typical IPS, web requests from your web browser (such as Google Chrome, Mozilla Firefox, Opera Mini…) are directly sent to a website server which you trying to connect. The website’s web server processes requests from your web browser and sends back data required by the browser to show you the web page. All of your online activities, browsing history, and usage data are recorded and saved by your ISP, so that they can use it in some ways if needed.
That’s the main problem with an ISP, your data is at their hands and can be used in many ways. Also, they are in control, they can restrict access to any website they want or limit your speed for certain websites. Usually, ISPs are limiting access speed with torrent websites or some of them completely block torrents.
On the other hand, VPN is “your own” network, your own Virtual Internet Service Provider where you are in full control, limitless in every way, free from any limitations and controls. Your data, browsing history & online activities are not recorded, is not monitored or controlled. You are allowed to visit any website you want, at maximum possible speed and only you can disable access or limit access speed to any website(s).
Here’s how VPN works: web requests from your web browser are sent to a secure VPN server, encrypted for additional security and forwarded to an original web server of the website you are trying to connect. Then, the website’s web server sends the requested data to a secure VPN server, the data is encrypted and sent to your browser. VPN software installed on your PC, Smartphone or Browser itself decrypts the encrypted data and gives it to the browser which is used by the browser to show you the webpage.
Just like that, best vpn services not only give you limitless access but also encrypting and protecting each bit of your data. Of course, for a VPN to work you also need internet connection from an ISP, but your ISP can’t see any of your real activities and data, their records are useless, harmless and they can’t limit or control you.
VPNs are used by many kinds of users, including ordinary persons who care about their online security and privacy, small & big offices, companies which need more security and more control over their employers and how they use internet access at the job.
What is Cloud Computing, why it is needed and who use it?
Cloud Computing is also a network, big network of servers & computers connected with each other in the cloud, connected to the biggest network – the internet.
Cloud computing is not used for a certain task, it can be used for a wide range of things, for everything that needs computing power, computer power & processing. It can be used to encrypt or decrypt big data in seconds, do huge calculations in no time, send & receive a large amount of data…
Cloud computing is used by larger companies and brands who need a lot of computing power, who have large data to process and transfer. Cloud computing is also used by developers and development teams who work on large projects. A VPN service providers also usually use Cloud Computing as it a flexible & secure way to process large data.
