1 E-commerce cloud computing infrastructure to build cloud computing as the future Network application architecture, emerging development. Cloud computing is a way to share IT infrastructure, and it can connect huge system pools and provide services. Cloud computing enables enterprise data centers to operate more like the Internet, allowing computing resources to be accessed and shared as virtual resources through secure and scalable methods. Virtualization is an abstraction layer that separates the physical hardware from the operating system, allowing for more granular cutting and consolidation of existing server operations and storage capabilities to deliver higher ...
