Private clouds are distributed systems that work on private infrastructure and providing the users with dynamic provisioning of computing resources. A private cloud is generally used within an organization. This helps to avoid the complexities and time associated with the purchase and cloud implementation of traditional physical infrastructure. Private cloud implementation also includes the challenges of integrating hardware and software from several vendors.
Features of Private Cloud:
- Higher Security And Privacy: Private cloud offers higher security as compared to public cloud services. Due to the limited access, Private Cloud provides more Security services.
- Improved Reliability: Private cloud offers virtually created operating environments which indicate that the network is highly flexible to individual failures.
- More Control: As the access to the pool of resources is restricted to one organization, the configuration, and management of private cloud can be aligned as per their needs for obtaining a customized network solution.
- Customization: Private cloud allows for greater customization of the infrastructure, applications, and services to meet the specific needs of the organization.
- Scalability: Private cloud can be scaled up or down according to the needs of the organization, without the need to share resources with other users.
- Compliance: Private cloud can be designed to meet regulatory compliance requirements, such as data privacy laws or industry-specific regulations.
- Cost-effectiveness: While private cloud may require a higher initial investment in infrastructure, it can be more cost-effective in the long run, as it eliminates the need to pay for public cloud services on a recurring basis.
- Hybrid cloud integration: Private cloud can be integrated with public cloud services to create a hybrid cloud environment that combines the benefits of both models, such as cost savings and scalability of public cloud with the security and control of private cloud.
So it is important to understand the components of the private cloud. The key expectations of private clouds are in demand. To provide some features the building blocks are required for private cloud which are as follows:
- Supports for Heterogeneous System: The cloud should support a wide range of products and vendors such as the latest hardware, software, and virtualization, open system, commodity hardware. The cloud manager product you select must support for the original manufacturers.
- Virtualization: This is the foundation of any cloud. The hardware resources, including the identity and the number of individual physical servers to form a pool of virtual machines. So the virtual machines must be worked with the elasticity.
- Service Catalog: A service catalog is a menu of applications that customers can choose from. The service catalog is a guide for users and customers.
- Self Service Portal: Self Service Portal gives a way for interaction between customers and cloud service providers. It is used to consume less amount of time. The offered services and resources should be easy for the end-user to configure and manage.
- Resource and workload manager: The cloud must-have a resource manager that allows it to easily meet varying workload, maintain service availability. It is done by moving applications to healthy hardware in the event of failure of servers and network links of other resources.
- Metering software and pay per use billing: The cloud must have metering software to track the utilization of software and hardware resources.
