A private cloud is a type of cloud computing that provides scalability and self-service capabilities like a public cloud but within a proprietary infrastructure dedicated to a single organization. It is a single-tenant environment where the organization does not share resources with other users. Private clouds can be hosted internally or by third-party providers and offer increased security, performance, and customization compared to public clouds but at a higher cost and with less scalability. Common types include virtual private clouds, managed private clouds, and on-premise private clouds. Major vendors include Cisco, Google, AWS, IBM, and Microsoft.

What is private cloud Explained
- 2. What is a private cloud? Private cloud is a type of cloud computing that delivers similar advantages to public cloud, including scalability and self-service, but through a proprietary architecture. A private cloud, also known as an internal or corporate cloud, is dedicated to the needs and goals of a single organization whereas public clouds deliver services to multiple organizations. A private cloud is a single-tenant computing infrastructure and environment, meaning the organization using it -- the tenant -- doesn't share resources with other users. Private cloud resources can be hosted and managed by the organization in a variety of ways. The private cloud might be based on resources and infrastructure already present in an organization's on-premises data center. The main advantage of a private cloud is that users don't share resources. Because of its proprietary nature, a private cloud computing model is best for businesses with dynamic or unpredictable computing needs that require direct control over their environments, typically to meet security, business governance or regulatory compliance requirements.
- 5. What is the difference between private cloud vs. public cloud? A public cloud is where an independent third-party provider, such as Amazon Web Services (AWS) or Microsoft Azure, owns and maintains compute resources that customers can access over the internet. Public cloud users share these resources, a model known as a multi-tenant environment. For example, various virtual machine (VM) instances provisioned by public cloud users may share the same physical server, while storage volumes created by users may coexist on the same storage subsystem. What is the difference between private cloud vs. hybrid cloud? A hybrid cloud is a model in which a private cloud connects with public cloud infrastructure, enabling an organization to orchestrate workloads -- ideally seamlessly -- across the two environments. In this model, the public cloud effectively becomes an extension of the private cloud to form a single, uniform cloud. A hybrid cloud deployment requires a high level of compatibility between the underlying software and services used by both the public and private clouds.
- 7. Is it better to use a public cloud or a private cloud? Some businesses may prefer to use a private cloud, especially if they have extremely high security standards. Using a private cloud eliminates intercompany multitenancy (there will still be multitenancy among internal teams) and gives a business more control over the cloud security measures that are put in place. However, it may cost more to deploy a private cloud, especially if the business is managing the private cloud themselves. Often, organizations that use private clouds will end up with a hybrid cloud deployment, incorporating some public cloud services for the sake of efficiency.
- 8. Advantage of private cloud? •increased security of an isolated network; •increased performance due to resources being solely dedicated to one organization; and •increased capability for customization, such as specialized services or applications that suit the particular company. •More Control Private clouds have more control over their resources and hardware than public clouds because it is only accessed by selected users. Security & privacy Security & privacy are one of the big advantages of cloud computing. Private cloud improved the security level as compared to the public cloud. Improved performance Private cloud offers better performance with improved speed and space capacity.
- 9. Disadvantage of private cloud? Private cloud technologies -- such as increased automation and user self-service -- can bring considerable complexity to enterprise IT. These technologies typically require an IT team to rearchitect some of its data center infrastructure as well as adopt additional software layers and management tools. 1) High cost The cost is higher than a public cloud because set up and maintain hardware resources are costly. 2) Restricted area of operations As we know, private cloud is accessible within the organization, so the area of operations is limited. 3) Limited scalability Private clouds are scaled only within the capacity of internal hosted resources. 4) Skilled people Skilled people are required to manage and operate cloud services.
- 10. Types of private cloud? • Virtual private cloud A virtual private cloud (VPC) is a type of cloud model that offers the benefits of a private cloud (more control and an isolated environment) with the help of public cloud resources. • Managed private cloud A managed private cloud is a type of private cloud model in which the infrastructure is not shared. • Hosted private cloud Hosted private cloud vendors offer cloud servers in their own data centers and are also responsible for security management. • On-Premise private cloud Unlike hosted private clouds, on-premise cloud solutions allow users to host a cloud environment internally. For such a cloud model, it is necessary to have an internal data center to host the cloud server.
- 11. Vendor of private cloud? •Cisco. The vendor provides its Quickstart Private Cloud to create a self-service private cloud environment along with varied platforms. •Google. The tech giant offers a virtual private cloud product that enables highly customizable network environments for hosting public or private workloads •AWS. Amazon Virtual Private Cloud lets users launch AWS resources in an isolated virtual network -- either on premises or through a remote managed provider -- to create a private instance of public AWS resources. •IBM. IBM offers private cloud hardware, along with its Cloud Managed Services, cloud security tools and cloud management and orchestration tools. IBM now owns Red Hat with its private cloud capabilities. •Microsoft. Azure Stack helps build and run applications across data centers and edge locations to remote offices or even the public cloud. •Oracle. Private Cloud Appliance X8 by Oracle enables compute and storage capabilities optimized for private cloud deployment.
- 12. Summary A virtual private cloud (VPC) is a secure, isolated private cloud hosted within a public cloud. VPC customers can run code, store data, host websites, and do anything else they could do in an ordinary private cloud, but the private cloud is hosted remotely by a public cloud provider. (Not all private clouds are hosted in this fashion.) VPCs combine the scalability and convenience of public cloud computing with the data isolation of private cloud computing. A private cloud is single tenant. A private cloud is a cloud service that is exclusively offered to one organization. A virtual private cloud (VPC) is a private cloud within a public cloud; no one else shares the VPC with the VPC customer.
