So in the enormous, interlaced world of cloud computing (where thousands of servers talk to each other at once) how are we to avoid digital havoc? How do we make sure the sensitive information of the billing department does not follow the unsecure web servers or the development traffic does not slug down the production programs?
The solution is not physically separating it, rather logical, virtual separation. This is the world of the Virtual Local Area Network or VLAN. VLANs are a basic technology that is supported by both the traditional and the modern cloud environment and serves as a platform that offers the framework and security to create efficient, scalable, and secure networks in the cloud.
This manual will clear up VLANs. We will define Virtual LAN, the principles of how VLANs operate, look in depth at the salient features of VLANs, and unravel the important benefits of VLANs (and the little bit of drawbacks) that have made them essential in cloud computing.
