Can someone tell me what is the difference between a private cloud and virtual private cloud? All guides that I’ve read so far left me more confused than informed. In NIST, there is no exact definition of the two so answers would be appreciated greatly!

Hello
where are 3 types of clouding: public, private and virtual private clouds
-
Public cloud is a public, hyperscale, multi-tenant platform where computing services can be reserved or rented on demand. These resources are available globally over the internet and allow customers to provision and scale services instantly without the time and CAPEX associated with purchasing dedicated infrastructure. The major providers are Amazon Web Services (AWS), Microsoft Azure and Google Cloud. All of these service providers offer infrastructure that is certified to run SAP.
-
A private cloud, in contrast, is a single tenant cloud environment that runs on dedicated infrastructure. This may reside on-premises, in a dedicated off-site data center or with a managed private cloud provider. Where public cloud is elastic and easily scalable, private cloud is constrained by fixed infrastructure. The advantage of the private cloud is control and exclusivity. It’s yours. There are no neighbors to share hosted resources with.
and at last there is Virtual Private Cloud
- A Virtual Private Cloud (VPC) is an option that bridges the two, offering the best of both cloud models. VPC’s function like a private cloud that run on public or shared infrastructure. How does this work? The VPC isolates one user’s resources from another’s using an individualized, private IP subnet, and are connected by virtualized networks including Virtual Local Area Networks (VLANs) or encrypted channels. Unlike public clouds that serve dynamic environments and all workloads, SAP VPC’s host similar and relatively static workloads. Because this is SAP, most customers access their environment through virtual private networks (VPN). This can reduce risk and exposure from neighbors that typically access their solutions over the public internet.
Hi @Wyatt
Private Cloud is a cloud infrastructure that is completely dedicated to one organization. Despite what many people think, Some hardware vendors think private cloud is a more secure public cloud. But to be exact, it refers to the exclusive use of a platform housing one organization’s data.
The reason that “private cloud” is not the best term is because the core definition of ‘cloud’ is that it must be elastic and scalable without the obligation to buy more hardware. So, by definition, an internal ‘private cloud’ should really just be referred to as ‘internal infrastructure.’
Virtual Private Cloud is the cloud in the way most people think of it. It’s like Amazon Web Services(AWS) or Microsoft Azure that we’re familiar with. These things are shared same infrastructure by a lot of people.
Virtual Private Cloud offer a level of isolation between customers through a private IP subnet, or Virtual Local-Area Network (VLAN), on a per customer basis. It’ll be easy to understand each word separately.
Hey there!
Although a Virtual Private Cloud and Private cloud may seem similar, they are not. A virtual private cloud (VPC) is a hybrid cloud computing model in which a private cloud is created within a public cloud provider’s infrastructure. Normally in a VPC, a portion of the public cloud infrastructure is provisioned for private cloud use. Virtual private cloud is primarily aimed for users who can take advantage of the public cloud computing while maintaining their sensitive data privately.
So, what makes virtual private cloud different from public cloud is that the VPC is hosted by third-party cloud vendors, whereas in a private cloud, it is hosted by the organisation’s own IT infrastructure. Some examples of VPC’s include Google App Engine and Amazon VPC.
Hello @Wyatt
In a private cloud model, the IT department maintains all the IT infrastructure in company’s own premises and provide the services to their own business unit. It can be maintained by IT department or
Cloud service providers, you will maintain servers in your premises.
In Virtual Private Cloud, You will get an isolated cloud in public cloud.
All the IT infrastructure such as servers, are maintained by Cloud service providers.
