The Role of VPN in Cloud Computing
Cloud computing has not only developed so much in the previous few years, but they also become ubiquitous. However, there are multiple things to keep in mind for moving from a physical system to cloud-based computing.
The first and most important thing that matters a lot is, of course, the security of the system. Now for physical systems, you can try surfshark VPN for PC while browsing online. However, the question arises of whether VPNs are useful for cloud computing.
In this article, we will learn about the role of a virtual private network in cloud computing.
So, let’s get into it!
The Role of Virtual Private Networks in Cloud Computing
Cloud computing is a relatively new concept in the IT world. Amazon Web Services (AWS) introduced it back in 2006 as an alternative to traditional data centers.
The idea behind cloud computing was to provide users with access to large amounts of resources over the internet instead of having them housed on-premises.
This way, users could pay for what they use rather than paying for all their infrastructure upfront. In addition, cloud computing allows companies to scale up or down based on demand with no major changes.
However, one of the biggest challenges faced by cloud providers is how to ensure user privacy and security. This is where VPNs come into play. A VPN provides secure connections between two different networks.
The main purpose of a VPN is to allow users to securely connect to remote locations using public networks such as the Internet.
Someone typically establishes a VPN connection through a tunneling protocol like IPSec or L2TP/IPsec. Once the tunnel is set up, users can browse websites anonymously and securely.
Benefits of Using a VPN with a Cloud Network
There are many benefits of using a VPN for cloud computing. For example, if your company uses AWS, then you can easily create a VPN connection to your office network.
You can do this by creating a VPC in AWS and connecting it to your corporate network.
Once connected, you can log in to your corporate network using your credentials provided by AWS.
You can even use the same credentials to log in to other services hosted by AWS, such as EC2 instances.
Another benefit of using a VPN for your cloud computing needs is that it gives you access to your company’s internal resources from anywhere.
For example, suppose you have a server running at home which you want to access remotely, and you can simply connect to your company’s VPN and gain access to your server.
Similarly, you can access servers located in other offices within your organization.
If you are looking to move your entire business to the cloud, then you should definitely consider using a VPN service.
It lets you connect to your existing corporate network from anywhere in the world.
How Does a VPN Work?
VPNs work by establishing a secure tunnel between two networks. When a client connects to a VPN server, the client sends its IP address to the server.
The server then looks up the IP address of the destination network. If there is no match, the server creates a new connection to the destination network. Once the tunnel is created, the client and the server exchange information via the tunnel.
By default, most VPN protocols encrypt traffic sent across the tunnel. However, some protocols also support authentication mechanisms. In order to establish a secure connection, both parties need to authenticate each other. The process involves exchanging certificates.
Certificates contain information about the identity of the sender. They also contain cryptographic keys used to protect data during transit.
Certificate-based authentication is commonly used in SSL (Secure Sockets Layer) and TLS (Transport Layer Security).
SSL/TLS is widely used to provide encryption and authentication over HTTP and HTTPS.

Last Minute Thoughts
To conclude the whole article, if you want to establish a secured connection to your cloud network, you will need to mask your IP address. This is where a virtual private network can come in handy for you.
With the help of a virtual private network, you can easily mask your IP address which will add an extra layer of security. Even if you are connected to public Wi-Fi, nobody will be able to sniff your data and steal your information.
Besides that, a VPN can provide you additional benefits such as unblocking the geo-restricted content, getting rid of the ISP throttling, and stuff like that. We hope you’ve enjoyed reading this article and learned how VPNs play an important role in cloud computing.
