is true for VMware's bridge. However, as a hardware Nic, VMware software virtualizes it! When bridging is used, VMWare will Virtualize a network card and a real physical network card to bridge the network card. In this way, all data packets sent to the physical network card will be sent to the VMware Virtual Machine, the data packets sent by VMware are also sent from the physical network card through the bridge. In this way, if the physical network card can access the Internet, there is no prob

not a Web service Confusion often occurs in understanding the relationship between SOA and Web services. According to a April 2003 Gartner report, Yefim v. Natis explains this problem: "Web services are technical specifications, and SOA is design principles." In particular, WSDL in Web Services is an interface definition standard for SOA: This is the fundamental link between Web services and SOA. "Essentially, SOA is an architectural pattern, and

heterogeneous environment is particularly important. WSDM (Web Services for distributed Management) stipulates that any service implemented according to WSDM can be managed by a WSDM adaptation (wsdm-compliant) management scheme. Other QoS features, such as communication and communication between partners, and the various service tasks are described in the ws-coordination and ws-transaction standards, all of which are oasis work.
