Introduction to Cloud Computing
Cloud computing is also known as internet computing that provides database access to users from internet without caring about management or actual resources maintenance. Besides, databases existing in cloud computing are very scalable and dynamic.Cloud computing is not like utility computing, grind computing or automatic computing, it is an independent platform. Google Apps is the perfect example of cloud computing where any type of application can be viewed via browser. In this way, it is easy to deploy it on millions computers using internet.
Key Characteristics:
Cloud computing is a cost effective solution as it reduces initial and recurring expenses than traditional computing. In cloud computing term, cloud is portrayed as independent device or location that is easily adoptable for all type of businesses. It provides you tremendous improved security due to usage of superior security system that is affordable for everyone. Another important feature of cloud computing is its salability that is attained via server visualization. In short, cloud computing is considered the best performing platform within affordable cost.
Cloud Computing Architecture:
The architecture of cloud computing is categorized into two parts.
Front end and back end:
Front end can be a common user or application that uses the services of cloud computing. While back end is the network of server connected to data storage and computer system. It is thought that cloud computing possesses unlimited capacity for storage of any available software.
Cloud contains centralized server system that balances supplies of client, monitors traffic, adjusts problems, and avoids congestion. This centralized server uses communication protocol named as middleware.
One assumption is related to the cloud architecture that is true. The demands of various resources in cloud computing do not remain always consistent. Due to this factor, cloud computing server fails to run at full capacity. Server visualization technique is applied to resolve this problem.
Data is the most essential part of cloud computing so the task of data security is placed at top priority in the data operation of cloud. Therefore, all data is backed up at various locations that increase the reliability of the system.
Different forms of Cloud Computing
Salesforce.com, Google Apps, and other online application use the technique of clod computing in form of software-As-service model. These applications are accessed through browsers from different location. This model is the most common form of cloud computing as it is beneficial for both the services providers and customers. There is no upfront investment for customers that they can pay-as-grow and pay-as-they go. While service providers can grow as the customers’ base grows.
Cloud Computing Concerns
Security of data like credit card numbers or SSN is very important issue. It creates a serious problem if unauthorized user accesses it. Cloud computing provides regulatory compliance methods for the administration and security of sensitive data. It is common thing to store data in one location while working on internet. However, cloud computing provides you some proper techniques for the security and confidentiality of data located at one place. It includes disaster recovery strategies to deal with unexpected events.
In short, cloud computing provide you reliable and great deal of solution for real time data storage and security issues. Cloud computing is the effective technique that will surely create robust demands in coming years.
