The pros and cons of using a virtual private cloud

Nancy J. Delong

VPCs (digital non-public clouds) have been really a marketing reaction by community cloud vendors that identified by themselves competing with non-public clouds, these kinds of as OpenStack, several years ago. Some enterprises did not relish the concept of inserting their data on a community cloud, sharing pooled resources with other companies—perhaps even their competitors.

I was in so several of people conferences back then, hearing CIOs proclaim that their data would never exist outdoors of their firewall. When relocating to cloud, it was heading to be their cloud in their data middle: a non-public cloud.

The issues with non-public clouds is that they even now have a subset of the exact functions and features as the community cloud vendors. Additionally, non-public clouds even now involve shopping for components and application, renting or shopping for data middle place, as very well as using the services of humans to consider care of it all. There was ordinarily destructive price to employing non-public clouds and no genuine protection rewards.

VPCs are defined a bit otherwise based on which cloud provider or MSP (managed expert services provider) you decide on, but they have a number of patterns in widespread:

  • Your processing and data storage techniques are not intermingled with other tenants. This is completed by employing bodily and digital mechanisms managed by the cloud computing provider. 
  • You will get a exceptional non-public IP subnet that you are going to leverage as if the components and application have been down the hall.
  • You will use protected digital communications, these kinds of as a VLAN or VPN. In some scenarios these connections use the open up World-wide-web in other scenarios they may possibly have a devoted circuit specifically to the cloud provider.

The benefits of a VPC are that you are in a position to functionally use your very own non-public cloud employing protected company and you are going to have access to all functions and features of the community cloud computing provider web hosting your VPC. There are also some drawbacks to consider.

Very first is the cost. Of training course, it relies upon on your community cloud provider or MSP, but in all scenarios a VPC prices much more to function than regular cloud web hosting. In some scenarios it is much more high-priced than running a non-public cloud on premises.
