Welcome to Yellow Circle Cloud - This video introduces students to basic components of a data center. Students learn to create a router, connect that router to public network, create a private network, create a subnet, define a DHCP server, establish connectivity between router & network. The final step is to launch a virtual machine inside your own virtual private data center. All this is done under six minutes. #freecomputerlab
