In this tutorial you will learn about the Private Cloud Model and its application with practical example.
Private Cloud Model
The private cloud model is described as computer services provided through the Internet or a private internal network to a limited number of customers rather than the broader public. The additional control and customization provided by dedicated resources over an on-premises computing infrastructure. Furthermore, private clouds give a better level of security and privacy by utilizing both corporate firewalls and internal hosting to ensure that operations and sensitive data are not accessible to third-party providers. One disadvantage is that the company’s IT staff is held accountable for the expense and management of the private cloud. Thus, private clouds are require the same costs for hiring, management, and maintenance as traditional data-center ownership.
A private cloud can provide cloud services in two ways. The first is infrastructure as a service (IaaS), which allows a business to employ infrastructure resources like computing, network, and storage as a service. The second is platform as a service (PaaS), which allows a corporation to deploy everything from basic cloud-based apps to complex corporate applications. Private clouds may also be integrated with public clouds to form a hybrid cloud, allowing businesses to use cloud bursting to free up additional space and expand computing services to the public cloud as computing demand grows.
A private cloud can be hosted in an organization’s own data center, at a third-party colocation facility, or through a private cloud provider who provides private cloud hosting services as well as typical public shared multi-tenant cloud architecture.
The end-user organization is often responsible for running a private cloud as if it were a regular on-premises infrastructure, including continuous maintenance, upgrades, OS patches, middleware, and application software administration.
Private Cloud Solutions provide enterprises with greater control and security over private cloud servers, albeit they do need a considerably higher degree of IT experience than using a public cloud.
Architecture of a Private Cloud
The aggregation of resources in a data center into a single pool of resources is known as private cloud architecture. Organizations improve the efficiency and use of their private cloud infrastructure by virtualizing physical components. Leading software businesses such as VMware, Microsoft, and others provide private cloud solutions, while Red Hat, OpenStack, and others provide enterprise-grade open source solutions.
Private cloud solutions enable businesses to design a data centre with software-defined networking (SDN) and virtual machines (VMs). A private cloud can span the globe, including several server sites or leased space in international colocation facilities. Private cloud solutions offer software tools for complicated network orchestration on bare-metal servers, allowing data security to be maintained.
- The term “private cloud” can also refer to an internal cloud or a business cloud.
- Instead of the wider public, a private cloud delivers computer services to a private internal network (inside the enterprise) and chosen users.
- Through firewalls and internal hosting, private clouds give a high level of protection and privacy to data. It also assures that third-party suppliers do not have access to operational or sensitive data.
- A private cloud is an example of HP Data Centers, Microsoft, Elastra-private cloud, and Ubuntu.
The Benefits of Private Cloud
The following are the benefits of Private Cloud:
1) Greater Control
Because private clouds are only accessible by a limited number of users, they have more control over their resources and hardware than public clouds.
2) Safety and privacy
One of the major benefits of cloud computing is security and privacy. When opposed to the public cloud, the private cloud provides more security.
3) Better performance
Private clouds provide superior performance, as well as increased speed and storage capacity.
