What is Virtual Private Cloud



The Virtual Private Cloud (VPC) is a completely separate, separated resource from a Public Cloud Infrastructure, based on the multi-tenant system architecture.

The salient features of Virtual Private Cloud – VPC:

– Rapid deployment: VPC service providers can provide needed resources immediately on their systems on demand. You can choose compute resources packages including vCore CPU, vRAM, IP, VLAN, and Storage according to your needs.

– Adjust / increase the resource (resource pool) for private use when needed in a simple way, and get immediate response from the service provider.

– Actively configure the network for Virtual Servers – VS (also known as Virtual Machines – VMs or Cloud Servers – CS) in the provided resource pool.

– Unlimited number of VMs created as long as the resource pool is not exceeded.

How VPC works?


In a virtual private cloud model (VPC), the infrastructure service provider (IaaS) is responsible for ensuring that each client’s data in the private cloud is still separate from the data of other customers. This can be done through the use of security policies such as: data encryption mechanism, tunneling, private IP address, allocation of a single Virtual Local Area Network (VLAN) for each customer.

Users (and IT administrators) virtual private cloud (VPC) can directly identify and manage network components, including public IP addresses, VLANs, network ports and configure control policies. access.

Differences between Private Cloud and Virtual Private Cloud

The term private cloud (Private Cloud) and virtual private cloud (Virtual Private Cloud) are sometimes used incorrectly or explicitly from service providers.

  • Private Cloud

There is a clear difference – in the traditional on-premise private cloud model. There, the internal IT department of the business acts as a service provider for other departments.

In some organizations, the provision of this service is calculated in detail to evaluate the performance of the IT department and the departments that use the service. However, for the most part, the IT department plays a more “free” role.

  • Virtual Private Cloud

With VPC, cloud computing infrastructure service provider (IaaS) plays the role of service provider and departments in the enterprise become users of cloud computing services.

Benefits and challenges of virtual private cloud – VPC

As mentioned above, one of the biggest benefits of VPC is that they allow an enterprise to exploit some of the benefits of private clouds, such as more granular network control. It is necessary to invest in building a system of private devices and still using resources on public cloud infrastructure. That helps improve the scalability (scale) of the system according to user needs.

Another great benefit of VPCs is the ability to deploy hybrid clouds. An enterprise can use VPC as an extension of an existing private data center, without having to deal with the complexity of building an on-premise private cloud.

And of course, a great benefit of VPC is that you only pay for the resources you use.

  • Challenges of VPC

However, VPC still faces some challenges. One of them is that administrators face a number of complex issues when configuring, managing and monitoring virtual private networks, VPNs.

While VPCs provide a separate environment on the cloud infrastructure, those workloads are, however, stored outside of the enterprise’s own data center. This means that for a few specific businesses, there will be strict laws / regulations on data storage mechanisms.

They then have to consider what data is allowed to run outside, on the cloud, and which data must run inside their own data center.
