How to operationalize Cumulus Linux

Thanks to the limitations of traditional networks, network operators are accustomed to doing everything manually and slowly. But they want to perform configuration, troubleshooting and upgrades faster and with fewer mistakes. They’re ready and willing to learn a new approach, but they want to know what their options are. More importantly, they want to do it right. The good news is, regardless of your organization’s specific goals, you can operationalize Cumulus Linux to meet those objectives faster and more consistently. This post will help you understand your options for developing agile, speed-of-business workflows for:

  • Configuration management
  • Backup and recovery
  • Troubleshooting

And if you’re looking for a deeper, more technical dive into how to implement these network operations, download this white paper.

Configuration management

Automation

The biggest disadvantage of manual configurations is that they simply don’t scale. Implementing BGP across dozens of switches is a copy-and-paste endeavor that’s time-consuming and prone to error. Not only that, checking that the configuration took effect and works as expected requires hop-by-hop verification in addition to testing route propagation and IP connectivity. However, In a small network, there’s no shame in at least starting out doing everything by hand.

Weekend Reads 071318: Nice to Haves

I had about four hours of highway driving yesterday. Even though I probably could’ve navigated it on my own, I opted to use Apple Maps, which is integrated with my car’s Apple CarPlay “infotainment center.” It was nice. It told me how many miles I had remaining and my expected time of arrival. But it wasn’t a life changer. @The Old Reader

More than ever before Internet users are now interacting with people living/working in other economies. And as a result of these interactions, there are an increasing number of ‘legal contracts’ (intentional or not). Internet policy researchers and academics debate about the changing landscape and the boundaries of the international and domestic laws, without conclusive agreements. —Yeseul Kim @APNIC

The plague that is Spectre continues to evolve and adapt, showing up in two new variants this week dubbed Spectre 1.1 and Spectre 1.2 that follow the original Spectre’s playbook while expanding on the ways they can do damage. —Curtis Franklin Jr. @Dark Reading

These vast routing events that are propagated globally already provide a hint that some ISPs do not set filters at all, or there are vastly malformed AS-SETs. We decided to measure the number Continue reading

Rough Guide to IETF 102: DNSSEC, DNS Security and Privacy

DNS privacy will receive a large focus in the latter half of the IETF 102 week with attention in the DPRIVE, DNSSD, and OPSEC working groups. In an interesting bit of scheduling (which is always challenging), most of the DNS sessions are Wednesday through Friday. As part of our Rough Guide to IETF 102, here’s a quick view on what’s happening in the world of DNS.

Given that IETF 102 is in Montreal, Canada, all times below are Eastern Daylight Time (EDT), which is UTC-4.

IETF 102 Hackathon

The “DNS team” has become a regular feature of the IETF Hackathons and the Montreal meeting is no different. The IETF 102 Hackathon wiki outlines the work that will start tomorrow (scroll down to see it). Major security/privacy projects include:

Anyone is welcome to join the DNS team for part or all of that event.

Two studies show the data center is thriving instead of dying

Once again research is showing that rumors of the demise of the data center are greatly exaggerated. One study shows across-the-board growth in IT spending, while a second predicts that the financial services sector is really set to explode.Market research firm IHS Markit surveyed IT managers at 151 North American organizations and found that most of them expect to at least double the amount of physical servers in their data centers by 2019.“We are seeing a continuation of the enterprise DC growth phase signaled by last year’s respondents and confirmed by respondents to this study. Enterprises are transforming their on-premises DC to a cloud architecture, making the enterprise DC a first-class citizen as enterprises build their multi-clouds,” wrote Clifford Grossner, senior research director in the cloud and data center research practice at IHS Markit.To read this article in full, please click here

IDG Contributor Network: Machine learning takes a load off in network management

As networks become more software-driven, they generate vastly greater amounts of data, which provides some challenges: adhering to compliance and customer privacy guidelines, while harvesting the massive amounts of data—it is physically impossible for humans to tackle the sheer volume that is created. But the vast amounts of data also provide an opportunity for businesses: leveraging analytics and machine learning to gather insights that can help network management move from reactive to proactive to assurance. This doesn’t just mean a massive shift in technology because the human element won’t simply go away. Instead, by combining human intellect and creativity with the computing power AI offers, innovative design and management techniques will be developed to build self-improving intelligent algorithms. The algorithms allow networks to operate in a way that far outweighs networks of the past.To read this article in full, please click here

Independence, Impartiality, and Perspective

In case you haven’t noticed recently, there are a lot of people that have been going to work for vendors and manufacturers of computer equipment. Microsoft has scored more than a few of them, along with Cohesity, Rubrik, and many others. This is something that I see frequently from my position at Tech Field Day. We typically hear the rumblings of a person looking to move on to a different position early on because we talk to a great number of companies. We also hear about it because it represents a big shift for those who are potential delegates for our events. Because going to a vendor means loss of their independence. But what does that really mean?

Undeclaring Independence

When people go to work for a manufacturer of a computing product, the necessarily lose their independence. But that’s not the only case where that happens. You can also not be truly independent if you work for reseller. If your company specializes in Cisco and EMC, are you truly independent when discussion Juniper and NetApp? If you make your money by selling one group of products you’re going to be unconsciously biased toward them. If you’ve been burned or had Continue reading

IDG Contributor Network: 4 ways data science services is helping businesses reach IoT goals, faster

Data scientists are an essential part of an IoT deployment. They fill a critical need to interpret data and provide valuable context around machine learning. However, as IoT initiatives expand and mature in a business, in-house data science resources can become thinly stretched. This creates a data pile-up that is a surefire way to set your deployment back.Hiring more data scientists is typically not an option either as there is a significant shortage in the market. Demand is only going up too: Gartner predicts that a shortage of data scientists will hinder 75% of organizations from reaching their full potential with IoT through 2020. Because hiring is difficult, time consuming and expensive, many organizations are turning to data science services to fill in resource gaps. Outsourcing data scientists has the dual benefit of helping keep IoT initiatives moving forward while freeing up internal resources to focus on other areas of the business.To read this article in full, please click here
