Virtualization – Cloud computing has taught us the benefit of virtualization at all levels where different entities may be spanned with a universal access pattern. The network is no exception and every network product tends to take advantage of this strategy.
Security and compliance – Every regulatory agency around the globe look for some kind of certification. Most network providers have to demonstrate compliance with one or more of the following: PCI-DSS, HIPAA/HITECH, FedRAMP, EU Data Protection Directive, FISMA, and such others. Security is provided with the help of identity and access management and they come in useful to secure individual network artifacts
Management – Network is very much a resource. It can be created, updated, and deleted. With software-defined technologies, the resource only takes a gigantic form otherwise it is the equivalent of a single data record for the user. Every such resource has also significant metadata. Consequently, we manage the network just the same way as we manage resources.
Networking is often considered a veritable alternative to storage as referenced in the paper on queues are databases by Jim Gray. But it helps to keep the baremetal considerations separate from the overall product perspective.
Monitoring – Virtual large networks may be stretched across members in one form or the other. And the physical resources such as edge and core members often have failures and run into faults. Therefore, monitoring becomes a crucial aspect.
