What is Private Cloud? Features, Benefits, and Why It’s the Right Choice for Your Business

Also referred to as an internal or corporate cloud, private cloud is a type of cloud computing environment where all resources i.e. hardware, software, and networks are strictly dedicated to only one organization. As compared to a public cloud model that shares its infrastructure across a number of users – private cloud extends a secure and customizable option that is tailored to meet the specific needs of the business.

In this article we will look into the features, benefits, and reasons why your business must adopt private cloud models.

What is a Private Cloud?

A private cloud is a cloud computing environment solely designed for a single organization. It is designed specifically for an organization, with all the hardware, software, and networking resources dedicated solely to that particular user or entity. This eliminates the possibility of shared infrastructure for other users. This means one gets full control over data, applications, and infrastructure.

Simply put, private cloud integrates the best of both worlds – the scalability, efficiency, and flexibility of cloud computing and the optimal security, control, and resource customization of on-prem IT infrastructure. Private cloud has emerged as an ideal choice for entities that handle sensitive workloads, such as those involving intellectual property (IP), confidential documents, or regulated data like financial information or medical records.

Key characteristics of private cloud include:

• Single-Tenant Environment: Resources are exclusively accessible to one organization.
• Customization: Customize the infrastructure according to your unique business needs.
• Improved Security: Run on a secure network, often behind corporate firewalls.
• Flexibility: You can adjust resources to match business needs.

Types of Private Cloud

1. On-Premises Private Cloud
   On-premise private clouds are hosted within the company’s data center and extend maximum control as they are managed by the organization’s IT team. However, these models require significant investment in both hardware and IT expertise.
   Some factors to consider about on-premise private cloud infrastructure are:
   • High initial cost: On premise private clouds require considerable initial investment in licenses, infrastructure, hardware and software. Constant maintenance and upgrades may also prove to be expensive.
   • More control: When compared to public cloud systems, private clouds offer more control and visibility into the infrastructure.
   • Highest level of security: Yes, private cloud models give you the highest level of security as the control is within your organization.
   • Scalability: On-prem private clouds are less scalable when compared to private clouds that are hosted by third parties.
2. Virtual Private Cloud (VPC)
   A virtual private cloud mimics the characteristics of a private cloud within a shared infrastructure.
   Some of the key components of VPC include:
   • Internet gateways: Which allow traffic between instances in the VPC and the internet.
   • Virtual private gateways: These gateways allow connectivity between VPC and on-premise networks through a VPN connection.
   • VPC peering: These are private connections between two or more VPCs.
   • NAT gateways: These facilitate instances in a private subnet to access the internet while blocking inbound internet traffic.
3. Hosted Private Cloud
   In the case of hosted private cloud models, third-party providers host the private cloud infrastructure in an offsite data center. This balances control with a reduced operational burden.
   Key characteristics of hosted private cloud include:
   • An independent computing power: Hosted private clouds offer a separate computing power for a single organization.
   • Quick entry point: Hosted private clouds offer an easy entry point, although at the cost of some control.
   • Off-premises: Hosted private clouds operate on a third-party vendor’s cloud servers, that are located off-premises.
4. Managed Private Cloud
   In managed private cloud models, an external third party takes the responsibility of the cloud, freeing the entity’s IT team to focus on strategic efforts. Moreover, in this model a third-party provider hosts the private cloud infrastructure in an offsite data center, balancing control along with reduced operational burden.
   Key characteristics of managed private cloud:
   • Security: Managed private clouds give higher security and privacy when compared to public cloud options. They can be designed to offer access only to approved users.
   • Control: Managed private cloud owners have complete control over their cloud infrastructure, including software, hardware, and security.
   • Cost: The cost of cloud computing can be managed by using cost optimization strategies for cloud configurations.

Benefits of Private Cloud for Your Business

1. Greater Control
   Private clouds offer a level of control that businesses have never had before. As opposed to public cloud environments, where resources are shared and managed outside, private clouds allow organizations to configure, monitor, and maintain their systems based on specific requirements.
2. Improved Security
   As a model, private clouds run in isolated environments that ensure that confidential/sensitive data remains protected i.e. cannot be accessed by unauthorized people. Advanced security measures such as firewalls, intrusion detection systems, and encrypted communication channels are usually included in these environments.
3. Cost Efficiency in the Long Term
   Although the initial investment to set up a private cloud is significant, the long-term savings are considerable. Private clouds do not charge subscription fees recurring based on usage like public clouds do. They also save a business money in terms of achieving cost efficiency in resource utilization and minimizing downtime, among other reasons, by cutting dependency on third-party services, with robust mechanisms for disaster recovery and redundancy.
