What is a Virtual Private Cloud what are its advantages?

3 Mins read

“The emergence of Virtual Private Cloud (VPC) offerings have helped to shift momentum from dedicated private cloud offerings toward the public (shared/multi-tenant) cloud offerings. By offering the attributes of public cloud (economics, scale, the pace of innovation) with some of the privacy and control features associated with private cloud, VPCs are effectively addressing many of the objections that have held customers back from the cloud model.” – IDC.

In this new digital era, where 7.4 billion people inhabit our world, everyone loves having his/her own private space. This need for some private space is all the more pronounced when you have some crucial data or information that cannot be exposed to the public. This is the digital era, majorly because of the cloud and this need for privacy is there even on the cloud, especially when you are on the public cloud. And this privacy in a cost-effective manner is provided by Virtual Private Cloud (VPC).

VPC is basically a hybrid cloud computing model in which a specific portion of the public cloud infrastructure is isolated and provisioned by the public cloud provider for private use. The public cloud vendor is responsible for the management of VPC infrastructure and the VPC resources allocated to a customer are not shared with others.

Thus, a virtual private cloud is the perfect solution for those seeking flexibility and elasticity of public cloud and the security associated with the private cloud.

Features of VPC:

  • It’s available on the self-provisioning model through the browser portal.
  • It’s also available as a managed service, where the cloud service provider manages configuration.
  • Firewall and load balancing comes included in VPC.
  • Is available on contract or on pay-as-you-go model.
  • It is very elastic and scalable.
  • The sizes of instances vary as per the customer requirements.
  • Is available with Windows or Linux OS options.

Working of a VPC:

Sometimes they are called as private clouds, but VPC is actually private cloud on a third-party cloud provider’s infrastructure, rather than cloud on an on premise IT infrastructure.

VPC allows you to run your applications inside an isolated virtual network that you define. It means you get the control over the internet gateways, subnets, and a range of IP addresses. The principle on which a VPC operates is exactly same as the connectivity solution provided by the VPN (Virtual Private Network).

As in VPN, the users share the network with a portion of it being dedicated for their private use, likewise, VPC users share the basic cloud platform only, with the virtual machines being dedicated for their private use.

Below are some use cases for VPC deployments:

  1. As VPCs are fully compliant and isolated, you can extend your off or on-premise infrastructure to a completely compliant cloud.
  2. With VPC, mission critical production apps can be securely deployed. Thus, it empowers businesses with highly secure cloud environment.
  3. It is ideal for those websites that are handling financial transactions and important data of their clients as customers want the secure and well-defined SLA.
  4. Using VPC for backup and disaster recovery allows you to restore and recover the important files, folders and applications, in the event of the website outage, data deletion or calamity.
  5. With VPC, you can easily meet the needs of the most demanding applications rapidly with the existing infrastructure without any additional cost.
  6. VPC can be used for testing purposes- complex systems can be created and latest applications can be tested by developers along with testing code in multi-tiered environment.

Virtual private clouds vs public clouds:

Like a public cloud, VPC offers scalable resources but in a controlled manner. Also, with VPC, each and every customer has his private vast resources’ pool, unlike public cloud, that can be expanded on-demand as per his growing business needs.

In addition to elasticity, VPCs also provide increased stability as compared to the public clouds, especially important in the case where production is involved as scalability and uptime are highly needed features.

There is also a higher degree of security with access to cloud computing resources and connectivity. Unlike accessing data through the internet like in the public cloud, enterprises accessing the VPC through the virtual private networks are able to access their confidential data more securely.

Thus, the benefits of virtual private cloud include all the benefits of public cloud in addition to increased security, predictability and cost-effectiveness. Now, you must be wondering which private cloud is best?

Utility and consistency requirements dictate the ultimate choice
