Taking shortcuts with changes can snowball into configuration chaos.
It’s amazing how interesting questions come in batches: within 24 hours two friends asked me what I think about writing books. Here’s a summary of my replies (as always, full of opinions and heavily biased), and if you’re a fellow book author with strong opinions, please leave them in the comments.

“There are things known and there are things unknown, and in between are the doors of perception," wrote Aldous Huxley. That could be a description of the evolving tension between the perceptions of hype and reality of the NFV market as it enters its important phase of commercialization.

Your questions from the HyTrust Intel webinar on a secure & compliant SDDC are answered here in this Q&A post. Take a peek!
NOTE Notice that we did not connect the Management1 interface of either vEOS instance to anything inside of GNS3. If you remember when we created the VMs, their first interface is a host-only adapter connected to the vboxnet in VirtualBox, so it’s automatically connected and there’s nothing additional we need to do there, but GNS3 doesn’t know that so it considers the interface disconnected, and that’s OK. That saves us from having to add our management server(s) to the topology and cluttering it up (Just imagine trying to have a nice clean-looking topology in GNS3 if you had to have a connection from every vEOS instance to the management server(s) ), which is distracting and ugly - we’re better than that. |
Edge provider networks, supporting DSL, voice, and other services to consumers and small businesses, tend to be more heavily bound by vendor specific equipment and hardware centric standards. These networks are built around the more closed telephone standards, rather than the more open internetworking standards, and hence they tend to be more expensive to operate and manage. As one friend said about a company that supplies this equipment, “they just print money.” The large edge providers, such as AT&T and Verizon, however, are not endless pools of money. These providers are in a squeeze between the content providers, who are taking large shares of revenue, and consumers, who are always looking for a lower price option for communications and new and interesting services.
If this seems like an area that’s ripe for virtualization to you, you’re not alone. AT&T has been working on a project called CORD for a few years in this area; they published a series of papers on the topic that make for interesting reading:
