Week 5 Posting - Cloud Connectivity and Troubleshooting

This week, the class went out cloud connectivity and troubleshooting. We learned how VLANs and common network connectivity tools work. I want to shed to light a recent technology that addresses the weaknesses of VLANs in a cloud computing atmosphere called VXLAN or virtual extensible LAN).

This overlay technology creates an “extended” virtual network on top of the current infrastructure. In terms of the OSI model, it is adding a layer 2 overlay structure above layer 3 (West, 2022, p. 183). The VXLAN header is inserted between the outer UDP header and original layer 2 frame. The header itself consist of the VXLAN flags and VXLAN network ID. An optimal time to use VXLAN is when the users need to accomplish any type of network segmentation that goes beyond what the original can deliver since VXLAN enables up to 16 million virtual networks.
