Cloud computing is by far one of the most impactful technologies that have transformed the way businesses have been conducted so far. This can be justified by the fact that cloud computing has given the entire process of data collection, storage, processing a phenomenal makeover. With scalability, virtualization and security patching across multiple systems placed physically in multiple locations almost in just a few steps. These features have improved the overall cross-functional coordination, customer relationship management and process delivery at the very organizational level. As a result, the HR vertical has significantly adopted cloud-based travel and expense management software as a service. Most significantly, there has been a massive overhaul in the product design around the cloud. Increasingly the software systems now are being developed to be more 'One' with the cloud and as result accessibility, user-centric interface and multi-platform integration are the principles of software architecture and design.
