The use of cloud computing is rapidly growing in all over the world. The clouds of information technology are commonly referred to as ââ?¬Å?Cloud Computingââ?¬Â. Cloud computing is a general term for anything that involves delivering hosted services over the Internet. Cloud computing is the next big thing after the Internet and it will revolutionize the way IT services are provided, due to its many advantages like Highly scalable, on-demand, web-accessed IT resources with major cost and flexibility. Various companies around the world using cloud computing as a means to increasing efficiency and reducing cost of their IT services. In this research paper efforts have been made to analyze the use of hybrid cloud computing model with security and scalability in business and information system. There are many challenges in using cloud computing. The main challenges are security and because all essential services are generally outsourced to a third party. The outsourcing makes it harder to maintain data integrity and privacy, security of data etc. Using public cloud model only in the business is very risky because of its security reasons and using private cloud only will not solve our purpose because in that case we are not be able to use advantages of public cloud model. To solve these security problems in business and information system we can use hybrid cloud computing model where we can use advantages of public cloud and security of private cloud, in which we can elect to store highly sensitive data of the company in the private storage cloud and less sensitive data in public storage cloud. This research mainly focused upon the security problems in business and information system. Research suggests a hybrid cloud computing model where converging advantages of public cloud and security of private cloud can be used.
