Disadvantages Of Cloud Computing
Cloud computing presents a solution for the previously stated business problem. Cloud computing involves delivering hosted services over the Internet. The three main categories are Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) (What is cloud computing?, n.d.). There are three deployment models for cloud services, which are private cloud, operated exclusively for an organization; a community cloud, shared by several organizations; and a public cloud, available to paying customers (Wilshusen, 2010).
Cloud computing is the concept that any computing device can access software applications via a web browser. As long as the device has an internet connection, it can share information with the cloud application. Servers in the cloud hold all the applications that the end users are able to access, as well as perform computations and data storage.
Cloud computing and mainframe computing have in common that applications are accessed from the server or the mainframe instead that on the end user’s computer. Cloud computing is different from traditional hosting because cloud services are completely managed by the provider and the users can specify the amount service and the time of the service (What is Cloud Computing, …show more content…
Cloud computing promises to reduce the cost of IT organizations by utilizing cloud’s economies of scale, which allows organizations to buy the exact amount of computing and storage needed at the exact time they need it (Wilshusen, 2010). Cloud computing has the potential to provide information technology services more quickly and at a lower cost (Wilshusen, 2010). There are also potential security benefits of the cloud, which include faster deployment of patches, and reduced disaster recovery costs (Wilshusen, …show more content…
Privacy, security, reliability and compliance are major concern for organizations considering the move to the cloud. Some critics claim that there are insufficient federal regulations governing how cloud providers must ensure privacy and security (Wilshusen, 2010). Cloud services create security risks, which include uncertainties about security practices and the controls of the provider and the loss of data if the cloud service is terminated (Wilshusen, 2010). Organizations are afraid to hand over control to the cloud provider, and have concern and questions such as: If all our services are in the cloud, what happens if our internet service is down or we cannot get to the cloud? Will cyber criminals target clouds because they present large rich targets? If you become unhappy with your cloud service provider how hard is it to move your data and services?
