Enterprises that want to segment their storage within a provider’s data center or host it entirely on their own premises often choose private cloud solutions, which store data and run compute processes that are separate from any other customer’s virtual infrastructure.
Although private clouds are typically more expensive, they give enterprises the option to better secure their cloud storage and compute environments. Private clouds also give organizations more control, allowing them to customize more elements of their cloud infrastructure.

Dell Virtual Private Cloud
Dell Virtual Private Cloud (VPC) is an infrastructure-as-a-service (IaaS) solution that comes from Dell’s partnership with Six Degrees Group (6DG), a cloud and managed service provider (MSP). PowerEdge blades provide compute for the private cloud, and Dell EqualLogic SAN is the storage solution. By connecting the Virtual Private Cloud to 6DG’s other cloud solutions, customers are able to create a hybrid cloud environment.
Dell Virtual Private Cloud users have access to managed backup; Dell also backs up all its virtual private clouds in a secondary zone in another geographic location, keeping the environments configured for high availability. Dell’s VPCs are ISO 27001 and PCI-DSS certified.
Virtual Private Cloud customers have the ability to put their backups in long-term archives. Dell VPC also supports seasonal scaling: if a business has a busy season and wants to increase their cloud capacity for that time period, they can scale back afterward. This is helpful for enterprises that need to rapidly scale resources.
Note that the VPC requires a 12-month minimum contract and is a fixed contract.
- Partnership with managed service provider 6DG
- Archiving option for backups
- Secondary geographic location for backed-up virtual private cloud environments

Microsoft Azure Stack
Microsoft Azure Stack is a cloud service that enterprises can run on their own servers and data centers as well as remote offices and edge servers. Azure Stack Edge is a managed appliance that provides an environment for edge workloads. Businesses can use Azure to build machine learning (ML) models and then install them and continue to train them at an edge deployment, so they’re specifically tailored to that location’s data. Consider Azure Stack if your business needs both an on-premises solution and edge locations to run applications.
Azure Stack Hub allows businesses to run an autonomous cloud on their organization’s premises, running Azure services there. Enterprises can disconnect their cloud environment partially or entirely from the internet or public clouds. Developers can design and deploy cloud applications that run in Azure and on premises.
Stack Hub users can use existing Azure serverless and microservices architectures for their private cloud. Azure Stack is an ideal on-premises cloud environment for organizations that already use an Azure public cloud and want to streamline cloud services across their own data centers and Microsoft’s.
- Managed appliance for running edge workloads, from which data can be sent to the customer’s on-premises cloud
- Other Azure services available on an enterprise’s premises
- On-premises application deployments for better management of regulatory compliance

Features of private cloud computing
Private cloud computing environments include virtual machines, which either run on an enterprise’s on-premises servers or on a vendor’s servers. Virtualization allows for more rapid server deployment and resource allocation.
Multiple deployment options
Private clouds can be deployed on-premises. On-premises private clouds run from an organization’s data center or office rather than a vendor’s. This method typically gives enterprises the greatest control over their cloud, because they can manage the physical environment.
Virtual private clouds are often managed by a public cloud provider, using the vendor’s existing cloud infrastructure but separated from other customer clouds.
Managed private clouds are handled by third-party vendors, which help businesses more quickly provision and deploy their cloud computing solutions. The vendor typically manages the customer organization’s infrastructure, so they don’t have to deploy their own.
Limited cloud access
Security-minded enterprises want to limit data and application access to those within their organization. While many public cloud solutions don’t give a complete list of who can access the data on the servers, private clouds are more suited to the stringent access controls of some businesses and industries.

Benefits of private cloud computing
Increased security: Because your computing, storage, or networking resources aren’t sharing the same cloud space as a public cloud, your enterprise has more control over the data security policies that govern information and system access.
Increased customization and flexibility: Although purchasing a private cloud solution from a cloud provider still includes any limits the provider has set, it’s generally still a more customizable option than a public cloud. This flexibility is useful for tailoring a cloud specifically to your organization’s infrastructure.
Increased opportunity to comply with regulatory standards: The customization of private cloud environments also means that businesses can more easily modify their private cloud to any regulations they have to follow. For example, an enterprise in the financial services industry might need to design their private cloud permissions to comply with any relevant financial statutes.
Private cloud use cases
“We wanted a scalable, responsive IT architecture with support for microservices, automation, and legacy systems, backed by enterprise support and security. … After evaluating different vendors, we found that Red Hat offers a complete, integrated software stack that could deliver what we need to support and grow our business. … With Red Hat‘s cloud-agnostic solutions, we can develop once and then quickly and easily deploy across on-site, private cloud, or public cloud environments with the same tools and web interface. By extending our public cloud solutions, with data processed on edge-deployed Red Hat OpenShift, our customers can use cloud resources in multiple regions through a unified interface, including geographical resource allocation in line with their edge strategies.” -Vladimir Smrekar, head of IT System Integration Department at Slovenian telecom company T-2, in a case study on Red Hat OpenStack, OpenShift, and Ceph Storage
“What Azure public and Azure Stack Hub give us is one plane of glass. When we provision our workloads in the public cloud, we see the same types of workloads — size, capacity, and usage. When I switch to look at our on-premises workloads, I see the same one in Azure Stack. I can see everything in the Azure portal. … When we needed capacity, we pushed our workloads into the cloud. I didn’t worry about waiting months for hardware. I knew I had capacity.” -Rajeev Siddappa, VP of infrastructure at Molina Healthcare, in a case study on Azure Stack
How to buy a private cloud solution
Decide whether a managed private cloud, hosted private cloud, or virtual private cloud will be best for your business. This is one of the first steps to take when purchasing a private cloud solution; from there, your business can narrow the search.
Communicate frequently with the vendor, discussing your enterprise’s cloud needs and ensuring that the private cloud solution will meet your particular use cases well. Look for indicators that the provider is receptive to questions and offers good customer service, especially due to the single-tenant architecture..
Consider what differentiates private cloud providers, such as container support, data storage formats, and open-source environment, and which vendor can match your specific cloud demands.
