Advantages and disadvantages of using virtual private cloud

VPCS have existed for at least a decade, but consider both sides of the coin before using them
The VPC (Virtual private cloud) is actually a marketing response by public cloud providers who find themselves competing against private clouds, like OpenStack, many years ago. Some businesses have not liked the idea of placing their data in the public cloud, sharing resources that are pooled with other companies, maybe even competing.

At that time I was involved in a lot of meetings when hearing CIO claiming that their data would never exist outside their firewalls. When switching to the cloud, that would be their cloud in their data center: a private cloud.

The problem with private clouds is that they still have a subset of the same features and functions as the public cloud providers. Furthermore, private clouds still require the acquisition of hardware and software, hiring or purchasing data center space, as well as hiring people to take care of them all. It's usually a negative value when using private clouds, and there's no real security benefit.
VPCS are slightly defined depending on the cloud provider or the MSP (managed service provider) that you choose, but they have several general templates:

Your data processing and storage systems are not interspersed with other tenants. This is done by using the physical and virtual mechanisms that are managed by the cloud provider.You will get a unique private IP subnet that you will leverage as if the hardware and software are active.You'll use secure virtual communications, such as VLANs or VPNs. In some cases, these connections use the open Internet; In other cases, they may have a dedicated circuit directly to the cloud provider.The advantage of VPC is that you can use your own cloud functionality by using security services, and you'll have access to all the features and functionality of the public cloud provider that stores your VPC. There are also some disadvantages to consider.

The first is cost. Of course, it depends on your public cloud provider or your MSP, but in any case, VPC will cost more than standard cloud storage. In some cases, it is more expensive than operating a private cloud at the facility.

You need to consider the cost of input and output of data moving into and out of the VPC, plus the cost of private connections per hour. There are also other additional features you can choose from, and it will win long until the value of a VPC turns red.
Latency can be an issue for people using VPC over the Internet that are open with private connections. Of course, this depends on where you're using a VPC related to physical presence points, chat application levels and VPN encryption types.

If you give me a choice of private or VPC cloud, I can select VPC for standard deployment. It never made sense to me to build entirely new hardware and physical software systems. Consider the lack of shares in the feature palette where the features that private clouds provide (and businesses require), with a few exceptions, are seldom private clouds an option.
