Cloud computing is one of today’s most attractive technology areas due to its many advantages like Highly scalable, on-demand, web-accessed IT resources with major cost / cash and flexibility. Various companies around the world adapting 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 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, support data and service availability 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 will not be able to use advantages of public cloud model. To solve these security problems in business 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 paper focused upon the security problems in business information system. Research suggests a hybrid cloud computing model where converging advantages of public cloud and security of private cloud can be used.
