Among the acts being…

Cloud migration is a necessary step for digital transformation, which is proceeding faster than planned at many enterprises because of the COVID-19 pandemic, according to research from Cloud Industry Forum (CIF), a cloud computing organization based in the United Kingdom. The cloud is an important steppingstone for getting off legacy on-prem technologies and outfitting today’s more flexible, remote workforce. Supporting a remote workforce requires a digital transformation, and to do that, companies need the cloud…

I’m back with another question related to model driven programmability.  This one came in from David Frizelle who came to the wonderful world of Model Driven Programmability through radio.  The new O-RAN Alliance (Open Radio Standard) is using NETCONF for configuration interface. How cool is that! Here’s David’s question: When considering a read only leaf in a YANG module, if a get or get-config is done in NETCONF, the read only leaves in the YANG…
