Networks are a key component of any cloud infrastructure. Managing and maintaining networks takes place at each of the layers in the OSI model from the low-level bits on the medium up to the application layer. Each layer must be configured and adapted to match the task at hand and each cloud has its own mechanisms and configuration options.
