The pros and cons of using a virtual private cloud

VPCs (virtual personal clouds) have been seriously a advertising and marketing reaction by general public cloud companies that discovered on their own competing with personal clouds, these types of as OpenStack, decades back. Some enterprises did not relish the idea of putting their details on a general public cloud, sharing pooled means with other companies—perhaps even their competition.

I was in so a lot of of individuals conferences back then, hearing CIOs proclaim that their details would never ever exist outside of their firewall. When moving to cloud, it was heading to be their cloud in their details centre: a personal cloud.

The issues with personal clouds is that they nevertheless have a subset of the exact same options and functions as the general public cloud companies. Additionally, personal clouds nevertheless involve getting components and application, renting or getting details centre house, as nicely as using the services of humans to just take treatment of it all. There was generally detrimental benefit to working with personal clouds and no true security gains.

VPCs are described a bit in another way dependent on which cloud provider or MSP (managed providers provider) you select, but they have a couple of designs in widespread:

  • Your processing and details storage methods are not intermingled with other tenants. This is attained by working with bodily and virtual mechanisms managed by the cloud computing provider. 
  • You will get a special personal IP subnet that you are going to leverage as if the components and application have been down the corridor.
  • You will use protected virtual communications, these types of as a VLAN or VPN. In some cases these connections use the open up World wide web in other cases they may well have a committed circuit immediately to the cloud provider.

The positive aspects of a VPC are that you’re in a position to functionally use your individual personal cloud working with protected company and you are going to have access to all options and functions of the general public cloud computing provider internet hosting your VPC. There are also some negatives to think about.

First is the price tag. Of system, it relies upon on your general public cloud provider or MSP, but in all cases a VPC prices much more to function than standard cloud internet hosting. In some situations it is much more expensive than running a personal cloud on premises.
