What is a Private Cloud?


Cloud computing is no more a buzzword for enterprises and organizations, the conversation has matured from “why cloud?” to ” which cloud?” One thing is clearly established ─ the true value of cloud lies in its ability to realize improved productivity, agility, scalability, resilience, and prompt user support. It’s on-demand computing services and availability of computing resources, have made it a leading technological resource. Let’s get to know more on the different types of cloud – Private cloud, Public and Hybrid.

Types of Cloud

Cloud service providers usually serve the cloud in three main categories:

  1. Public Cloud

  2. Private Cloud

  3. Hybrid or Multi Cloud

In a public cloud, the cloud infrastructure is designed in such a way, that it can serve the organization’s resources to millions of people. AWS, AZURE, GCP, etc. are examples of such a type of cloud. The hybrid cloud is a combined architecture of the private and public clouds. This read is all about the private cloud, its benefits, types, how it works and what Tata Communications solutions offer via IZOTM Private Cloud. Let us take a look at what is a private cloud.

What is a private cloud?

People ask this one common question – what is a private cloud? Private cloud is an on-demand proprietary computing model, hosted privately. It is either remotely served through a third-party cloud provider or hosted inside an organization. Unlike a public cloud, it does not share its resources with anyone. The companies that take the rent of private cloud often use it to preserve their proprietary resources that are critical and sensitive at the same time. These types of resources are not available publicly and are not shared, by any means without legal authorities. An enterprise experiences better security and control in case of a private cloud than a public cloud, because of the sensitive data residing in it.

Private clouds are meant exclusively to the company that wants its resources and computing. That is why the cloud providers offer an enhanced degree of control and management over their data. Because of the exclusive accessibility provided to the organization in case of private cloud, that organization gets the advantage of uniquely tailor and configuring the cloud environment to particular needs. Traditionally, private clouds used to run on-premises, but organizations are shifting towards a rented private cloud, where the data centres are located off-premises with the vendor. Also, you will get flexible cloud storage for preserving an organization’s sensitive data.

Private cloud vs. Public Cloud –

There is a vast difference between a private cloud and a public cloud.

  1. Private cloud also known as an internal cloud or enterprise cloud, is securely hosted by cloud providers with multiple layers of security protection. Public clouds on the other hand are a shared resource and security is much less compared to the former.
  2. Private cloud and its services are not shared, with different organizations, due to the collection of sensitive data residing in it. In contrast, multiple customers share the public clouds, but the data and services run by various customers in the cloud remain hidden. It is one of the significant differences between a private and a public cloud.
  3. One can compare a public cloud as a rented apartment or room with multiple rooms for many customers; whereas a private cloud is like renting a complete house with all possible privacy intact.
  4. Private clouds are mostly managed and configured internally by an organization because of the nature of sensitive and dedicated data residing within. That is not the case for public clouds, as the cloud provider can also configure and manage the space, who also entertains other tenants. That is another significant difference between the two.
  5. Private clouds allow a broad possibility of reconfiguration while using its computing services. The on-site cloud architect is responsible for constructing and configuring the exact environment required to run proprietary apps and services. In contrast, the Public Cloud is not much re-configurable and available in the pre-defined configurations.

There are various other technical differences, but these are the primary differences between and public and private cloud.

Benefits of private cloud

Apart from bringing value to an organization by isolating the computing processes to a single hand, it also offers versatility, the security of data, lowering down the cost, and controlling the configuration. Let us discuss some of the significant benefits

  1. Scalability

    With the increase in the resources and computing power, private clouds can scale up accordingly keeping the isolation of data preserved. In case the growth of data degrades or remains seasonal, the enterprise can switch to hybrid cloud solutions, incurring minimum usage fees by leveraging the public cloud in conjunction.

  2. Smooth performance:

    As the hardware in a private cloud is a dedicated one and with a choice of single-tenant or multi tenancy. The enterprise can enjoy the Cloud benefits like scalability, agility or resiliency while staying Private.

  3. Predictable cost

    The cost of Private Cloud is predictable and it’s mostly based on a pay-per-use model.

  4. Complete control and better security:

    Private clouds allow full control of the system, which helps in tweaking the security configuration as per the customer requirement. The organization that owns it manages the configuration and control of dedicated hardware exclusively. It is one of the most significant benefits.

  5. High customization capability:

    Since private cloud offers dedicated hardware to its consumer, reallocation of resources and tailoring the cloud for better performance can be achieved specifically according to defined requirements of the enterprise. Also, the on-premises cloud managers and senior cloud architects have access to each level of cloud environments, where they can set their policies and terms for lower-level accessibility.

How does Private cloud work?

Like other types of cloud environment, private cloud computing capabilities also get delivered through virtualization technology. Virtualization technology is the underlying concept of all cloud types. When servers remain underused, virtualization reduces the wastage by improvising resource utilization. In this process, the workload gets deployed to multiple servers with the fluctuation of resource demand. virtualization technology changes the combined computing resources into a shared pool of interconnected resources that are automatically provisioned and managed based on workload and computing needs. It makes a firm reasonable enough to scale and handle resource usage at a minimum cost.

According to one research, a private cloud can reduce the expense of an organization to a large extent. According to the research experts, a large cluster of charges remains hidden in the services the customers are not even aware of, in case of a public cloud. The research also shows that 41% of CTOs and IT decision-makers find private cloud as a cost-effective solution. The working structure of a private cloud is comparatively more modest because the customer gets a dedicated server to operate, and the computing resources are exclusive to one particular firm only. Due to the lack of multi tenancy feature, the organization do not share its dedicated hardware to other tenants. The intranet within a company can allow access to the private cloud, and in case of remote accessibility, an employee has to route through a Virtual Private Network (VPN).

What customization parameter is noteworthy while adopting a private cloud?

It is essential to keep in mind that there is a cost per VM (Virtual Machine) constraint. A business must decide how many VMs the organization should deploy, because of the costs per VM, per month. Although cloud computing has given enough flexibility to tweak with its pay-as-you-go model, for understanding the price variable completely, consumers have to compare some of the leading-edge private cloud vendors. TATA Communications is one of them.
