What is Virtual Private Cloud, How it Works?

Virtual Private Cloud

In this blog post, we will explore what is Virtual Private Cloud (VPC)? and how does it work? So, let’s get started!

What is Virtual Private Cloud (VPC)?

VPC is a hybrid model of cloud computing where a secure private cloud solution is hosted within a public cloud infrastructure.

With VPC any company can build its own secure private cloud-based environment on top of a shared public infrastructure. By doing so, the companies will have full access to the server and don’t have to share the resources.

The things that private cloud can also be a VPC ie: storing data, running codes, hosting websites. However, the only limitation is that the virtual private cloud is generally offered by the public cloud vendor.

VPCs collectively offer the scalability and comfort of public cloud computing along with the security and isolation of a private cloud.

Working of a VPC

Having discussed above what a VPC is, let’s see the working of virtual cloud.

VPCs use virtualization technology to build virtual machines on top of a physical server. These virtual machines can work independently with their own operating system and software.

As we discussed above, a virtual private cloud builds a private space in the public cloud and keeps aside the additional computing resources of the public cloud for itself.

The principal technologies that isolate a VPC from other public cloud are:

Subnets: Basically, the subnet is a range of IP addresses within a network that is dedicated to the company having ownership of a particular VPC. This helps in segregating a specific part of a network for private use. This range is not visible to the wider public and can be accessed only by the owner.

VLAN: A virtual local area network or VLAN is slightly different from a LAN. In the case of a LAN, several computers are connected with each other and restricted to a specific geographic area. Whereas in the case of a VLAN multiple LAN segments are created with just one bandwidth.

VPN: VPN or virtual private network uses an encryption key to create a secure and private network that encrypts the company traffic. So it can’t be accessed by anyone else.

Basically with VPC, you get subnets, VLAN, and VPN that is capable of providing you with data privacy and security.

Now let’s see the difference between Virtual Private Cloud and Private Cloud.

Difference Between Virtual Private Cloud and Private Cloud

People often get confused between a virtual private cloud and a regular private cloud. This is absolutely normal as they sound similar.

A regular private cloud houses just one tenant, the whole server is for just one company.

The public cloud houses several tenants on an IT infrastructure.

VPC on the other hand is a private cloud in a public cloud. You get the best of both cloud computing models i.e flexibility of public cloud and security of the private cloud.

I hope this article helped you understand what is virtual private cloud, how it works, and the difference between virtual private cloud and private cloud.
