Private cloud is generally used within a organization. This helps to avoid the complexities and time associated with 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 the public cloud services. Due to the limited access Private Cloud provides more Security services.
Improved Reliability –
Private cloud offers virtually created operating environments which indicates 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.
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 as follows:
- Supports for Heterogeneous System
- Virtualization
- Service Catalog
- Self Service Portal
- Resource and workload manager
- Metering software and pay per use billing
These are explained as below –
1. Supports for Heterogeneous System-
The cloud should support wide range of products and vendors such as latest hardware, software and virtualization, open system, commodity hardware. The cloud manager product you select must support for the original manufacturers.
2. Virtualization-
This is the foundation of any cloud. The hardware resources, including the identity and the number of individual physical server to form pool of virtual machines.So the virtual machines must be worked with the elasticity.
3. Service Catalog-
A service catalog is menu of applications that customers can choose from. Service catalog is a guide for users and customers.
4. Self Service Portal-
Self Service Portal gives an 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.
5. Resource and workload manager-
The cloud must have resource manager that allows it to easily meet varying workload,maintain service availability. It done by moving applications to healthy hardware in the event of failure of servers and network links of other resources.
6. Metering software and pay per use billing-
The cloud must have metering software to track the utilization of software and hardware resources.
So finaly after you have measured the requirement and components you can plan for the deployment of cloud. There are the components of private cloud.
