Online Virtual Operation Stage with Groupware using cloud computing

COMPUTER ENGINEERING

Cloud computing has experienced significant growth and maturation since Amazon introduced its pioneering cloud services in 2006. Hong Kong, with its extensive data processing needs across diverse sectors, stands to benefit greatly from cloud computing. Despite a slow start, there are clear signs that local companies are poised for a rapid surge in adopting cloud services. In the field of computer science, cloud computing now reigns as the foremost research theme, given its far- reaching implications in various computing sectors, particularly in handling big data, which would be challenging without the support of cloud computing. The establishment of a major cloud R&D Centre in Hong Kong by Lenovo in January 2015 underscores the significance of this fact. Cloud computing represents the long- awaited realization of computing as a utility, with the potential to revolutionize a significant portion of the IT industry. It enhances the appeal of software as a service and reshapes the landscape of IT hardware design and procurement. Developers with innovative ideas for new Internet services no longer face the need for substantial capital investments in hardware for deploying and operating their services. They no longer need to worry about overprovisioning for services that may not meet their predicted popularity, thereby avoiding the wastage of costly resources. Likewise, they can avoid under provisioning for services that become extremely popular, which would result in missing out on potential customers and revenue. Additionally, organizations involved in extensive batch-oriented tasks can achieve results with remarkable efficiency, as their programs can seamlessly scale. Leveraging the power of 1,000 servers for just one hour incurs no additional costs compared to using a single server for 1,000 hours. This unparalleled flexibility of resources eradicates the necessity of paying a premium for operations at a large scale, signifying a momentous achievement in the history of IT.
