The Right Way To Automation

By | Blog | No Comments

It is a pretty well-known fact by now that the internet outage on Nov 6 was a direct result of a configuration error. What is not known is just how such a common occurrence in the network, a config change, could have been allowed to happen at a time and in such a way that it caused such a massive problem across the country. Every time an engineer touches the network using the common processes and techniques in place today this kind of thing can happen. That doesn’t mean that every…

Intent Based Automation Is Complex, But It Shouldn’t Scare You

By | Blog | No Comments

In the last year the SDN/NFV hype peaked and people moved on to an automation focus in general. It always comes back to automation eventually, but this time a new term has gotten hot. Intent Based Networking, which is something I discussed in a blog about 2 years ago. The beauty of the emergence of Intent Based Networking as a hot topic is that it is a byproduct of automation done correctly. Now, what do I mean by that? If you do automation correctly you are moving to a model-based approach….

Modeling: Where We Are And Where We Need To Go

By | Blog | No Comments

We at Itential tout modeling all the time. We use it in our integrations with the Cisco Network Service Orchestrator (NSO) when working with its YANG models and Device Templates. We often tout it as the answer to the limited scalability offered by a scripting approach to automation, but we rarely talk a lot about the reality of where we are now in the industry when it comes to modeling. A recent blog I read talks about this in a thought provoking way that deserves some consideration. Everybody seems to…

Ops Automation: A New Year, Same Old Challenges…With New Answers

By | Blog | No Comments

As we move into a new year some things have become very clear. Some of these are things we have known for a while, some are revelations from working with clients, and some are things we SHOULD have known all along. There are many efforts going on within service providers and enterprises alike at the moment. There is the work to maintain legacy operations and service offerings under the weight of declining, or at best stable, revenue with a constant, and sometimes increasing, cost of maintenance. There is the effort…

The Secret Sauce of NFV? Operations, With A Side Of Automation…

By | Blog | No Comments

This is probably not what a lot of the technology vendors want you to know. They want you to keep thinking that the secret is that new controller they offer, or maybe containerization of their cool new VNF. All of those things, and more, do indeed matter, but they are not what is going to make or break your NFV implementation. An article the other day by Scott Raynovich on SDx Central points this out, and does a pretty good job of backing up the core message we at Itential have been trying to preach…

Orchestration, Orchestration Everywhere…What Are We To Do?

By | Blog | No Comments

One of the most overused phrases in the industry is orchestration. This is the case now, it was the case in the past, and it probably will continue to be in the future. It seems to be everyone’s answer to everything. Every vendor that has an “orchestrator” will promise you they can do anything you want, and this is true if you give them enough time and pay them enough money. You can “orchestrate” anything. So what is orchestration and why should you care about it. An orchestrator automates and “arranges”, to…

What is your Intent?

By | Blog | No Comments

Wouldn’t you love to be able to just tell your network to turn up a VPN for customer x between their Chicago office and their New York office that needed to be able to easily handle video traffic and it just knew what to do? Welcome to the world of Intent Based Networking! In the course of talking about this (not so) new idea we will discuss just what it is, what it is supposed to deliver, and the reality of where we are now and what needs to happen…

The Dynamic Service Catalog

By | Blog | No Comments

As we work with customers we notice many things about this new landscape that is being introduced. Some of these things are very network-centric, most are very operations-centric, and some of the most interesting are OSS-centric…especially in the area of Service Catalogs and Service Inventories. The changes being injected into the network are causing a bottoms-up wave of impacts that move through the management domains, sometimes causing chaos and other times providing a refreshing level of clarity to how things should have been done all along. Traditional OSS has focused on…
