Analyzing Cloud Computing: Hybrid Clouds, Benefits, and Virtualization

This report provides a comprehensive overview of cloud computing, starting with a definition and exploring its advantages and disadvantages. It highlights the economic benefits of adopting cloud platforms, such as reduced capital and operational costs. The report also discusses the virtualization of cloud technology, outlining benefits for both companies and data centers, including increased efficiency and reduced energy consumption. Furthermore, it delves into the evaluation of hybrid clouds, covering key considerations like base platform choice, vendor lock-in, tool scalability, public vs. private cloud selection, centralized management, multiple user access, performance and functionality, GUI quality, API access, scripting support, cross-cluster synchronization, and cost analysis. The document provides a thorough analysis of the factors involved in successfully implementing and managing cloud computing solutions.

What is Cloud?
• Cloud computing is a service that is delivered using the internet and using cloud computing
an user can access application, files from different device and different geographical
location. Different hardware and software is used for delivering the service in then network.
• The cloud computing is used for different purpose such as file storage, backup of data, data
analytics, etc.
Advantages and disadvantages of moving to cloud
platform
Advantages
It helps in saving the capita cost because there is no requirement of deployment of in house server
and thus eliminated the maintenance cost of the servers. The operational cost such as power, air
conditioning and administration costs are also discarded with the adoption of the cloud platform in
the business. The payment is done for the service that is used and the requirement of the
investment is eliminated. Three increase in the availability of the data in the cloud platform and it is
much more reliable than the in house server platform. The service level agreement is used for
guaranteed service and it allows the business to forget about the technical upgrades and
maintenance of the resource. The key business activity can be focused without having concentration
for the management of the servers and thus the business organization can grow its business.
Disadvantages
During the upgrades of the servers the service provided may get temporarily suspended and thus
the business may face difficulty during the maintenance period.
Even though the cloud service providers follows the best security standards but the user may feel
risk to store the important files and information with the external service provider.
The cloud computing is evolving and the user may face difficulty while moving to different cloud
services and migrating from different vendors.
Economic benefits for the adoption of cloud
• The implementation of cloud computing in the current business helps in reducing the capital
expenses required for the in house server and application.
• The operational cost can also be reduced such as air conditioning, administration and power
costs.
• The payment is given for the usage of service and the need of investment of capital is
eliminated.
• Affordable even for the small scale business enterprise and can grow with the growth of the
business.
Virtualization of cloud technology
Benefits for the company

• Removal of utility requirement and special hardware
• Increasing the efficiency of resource management
• Increasing the productivity of the employees by providing better accessibility
Benefit for the Data centre
• Server capability maximization and reduction of operation and maintenance cost
• Less consumption of energy and manpower causing less footprint
Evaluation of hybrid clouds
Base platform choice – the business needs are analyzed and the service provided by different vendor
are evaluated for the selection of the vendor.
Vendor lock -in – It should be analyzed that the requirement is meet by the same vendor
Tool scalability – It should be analyzed that the larger size of cluster can be managed or not and the
restricted products should be avoided.
Public or private cloud – The selection of the cloud is important for managing a wide variety of cloud
and enabling communication between the different cloud platform.
Centralized management – It should be analyzed that the tool is able to work as a single workstation
for achieving the goals and objectives of the organization.
Multiple use – Multiple user account should be created and the user can simultaneously access the
cloud platform.
Performance and functionality – The criteria for the requirement and the criteria of the cloud
management tool is selected for the identification of the functionality and the performance of the
system.
GUI – The quality and simplification of the graphical user interface is important for the development
of the hybrid cloud infrastructure.
APIs – the application that needs to access the APIs should be analyzed for the selection of the cloud
platform and the service provided by the vendor.
Scripting – The support of scripting and if the scripts have a variety of tools for clouds should eb
analyzed.
Cross cluster synchronization – The version synchronization across the cluster nodes should be
identified for the selection of separate tools.
Cost – The price of the different range of hybrid cloud should be identified and the evolving
technology should be evaluated for the selection of the cloud service.
