Private Cloud Advantages

Private clouds are ideal for businesses that handle sensitive data, need additional assurances or flexibility / customisation, and businesses that require tailored secure storage solutions.

Public clouds operate as large multi-tenant platforms, often open to all, and are managed by third-party providers. This makes them suitable for businesses and individuals that are looking for easy scalability and minimal initial investment.

Private clouds tend to be preferred by organisations that prioritise security, control, and customisation, while public clouds are generally chosen for their cost-effectiveness and relative ease of use.

What Is A Private Cloud?

A private cloud is a cloud computing model offering dedicated services and resources to a client.

Unlike public clouds, which cater to multiple clients, a private cloud is typically used by a single business or organisation for a specific purpose.

It can be hosted internally, in a data centre elsewhere, or by a third-party hosting provider.

The essence of a private cloud lies in its exclusivity and heightened security, making it an ideal choice for businesses prioritising data privacy and stringent control over their IT infrastructure.

How Private Cloud Works

Private clouds operate on dedicated physical and virtual servers, distinguishing them from the shared resources characteristic of public clouds. As a typical example, multiple customers will not utilise a shared IP address or database server for their website or web application hosting – each customer will have their own network and dedicated machines / resources.

Resources like SSD, RAM, and CPU will be reserved and allocated exclusively to a single organisation.

Access is meticulously controlled, often by a supporting IT department, ensuring that only authorised users can tap into the business’s digital assets. This access will be monitored by a Network and Security Operations Centre (NOC / SOC).

Accessing a private cloud could be conducted through a web browser, although some prefer using client software for an added layer of security, and in some instances, security policies dictate that access via the web is prohibited. Moreover, private clouds offer scalability, allowing businesses to adjust resources according to their needs.

Types of Private Cloud:

  1. On-premises Private Cloud: This variant is physically located within the business’s premises, offering full control over all components like hardware, software, and networking. The customer will be responsible for the build, maintenance and support themselves.
  2. Managed Private Cloud: Managed by a third-party hosting provider, this type of private cloud relieves businesses from the intricacies of setup and infrastructure management and support while still providing internal control over data management. This model allows the customer to outsource complexities, cost and risk.
  3. Virtual Private Cloud: Residing within a public cloud, a virtual private cloud offers the scalability of public clouds with the security of private clouds, ideal for businesses requiring both flexibility and stringent data privacy.

Advantages of Private Cloud

  1. Robust Security: Being accessible only by a specific business, private clouds offer a security level that is hard to breach. Administrators have the ability to grant and revoke permissions, tailoring access as per business needs. Dedicated monitoring and security tooling is utilised to ensure ongoing security and compliance.
  2. Control: Businesses enjoy control over resource allocation, infrastructure, and network settings, allowing them to tailor the private cloud sizing and features to their exact requirements.
  3. Scalability: Private clouds are not static. They can grow or shrink in resource allocation, aligning perfectly with the business’s evolving needs, without the requirement to procure and maintain expensive hardware or software.
  4. Data Loss Prevention: Features like backup and disaster recovery are inherent in private clouds and part of the design, safeguarding businesses against data loss due to emergencies.
  5. Cost and Resource Efficiency: Private managed clouds prove to be cost-effective in the long run due to predictable costs and efficient resource utilisation.

Disadvantages of Private Cloud

While private clouds offer numerous benefits, they are not devoid of challenges.

For an on-premises private cloud the initial setup cost can be steep should you opt to develop and build your own private cloud, and they require specialised management and ongoing maintenance, particularly in large business settings.

Hiring of additional staff to support the private cloud, and procurement, configuration and setup of additional software can be costly, complex and time consuming.

A business must also develop the supporting process and workflows to ensure ongoing operation, management and maintenance of their private cloud.

Private Cloud vs. Public Cloud

Choosing between a private and a public cloud ultimately boils down to the specific needs of a business. While private clouds offer unmatched security and control, public clouds are cost-effective and have a rapid deployment time.

The decision should be guided by factors such as the sensitivity of data, regulatory compliance requirements, and the need for resource scalability.

Public clouds can also often have hidden fees for data transfer and other components that are not clear when initially procuring and building your systems.


Private clouds represent a paradigm of secure, controlled, and customisable cloud computing. They offer a sanctuary for businesses that prioritise data privacy, demand robust security measures, and prefer a tailored IT infrastructure.

While the initial investment and management requirements could be more substantial for a managed private cloud than a managed public cloud, the long-term benefits – from security to cost savings – make private clouds a compelling choice for businesses aiming to solidify their digital infrastructure.
