Lessons Learned From A Regional Provider Network

Running and building a regional provider network is a challenging proposition. When your network is your profit center, every decision is made through a different lens. Add a global pandemic on top and you’re certainly going to walk away with a few lessons learned. In this episode we talk with Marek Isalski about his experiences building and operating a regional provider network in the UK.

How to manage your power bill while adopting AI

Artificial intelligence (AI) and machine learning (ML) can be invaluable tools to spur innovation, but they have different management requirements than typical enterprise IT applications that run at moderate CPU and memory utilization rates. Because AI and ML tend to run intense calculations at very high utilization rates, power and cooling costs can consume a higher proportion of the budget than an IT group might expect.It's not a new problem, but the impact is intensifying.As more CPU-heavy applications such as data warehousing and business intelligence became prevalent, IT was often oblivious to the electric bill it was racking up – particularly since the bill usually goes to the ops department, not IT.To read this article in full, please click here

Repost: VMware Fault Tolerance Woes

I always claimed that VMware Fault Tolerance makes no sense. After all, the only thing it does is protect a VM against a server hardware failure… in the world where software crashes are way more common, and fat fingers cause most of the outages.

But wait, it gets worse, the whole thing is incredibly complex – you might like this description Minh Ha left as a comment to my Fifty Shades of High Availability blog post.

God Objects Considered Harmful

Every software developer has run into “god objects”—some data structure or database that every process must access no matter what it is doing. Creating god objects in software is considered an anti-pattern—something you should not do. Perhaps the most apt description of the god object I’ve seen recently is you ask for a banana, and you get the gorilla as well.

We seem to have a deep desire to solve all the complexity of modern networks through god objects. There was ATM, which was going to solve all our networking problems by allowing the edge device (or a centralized controller) to control the path its traffic takes through the network. There is LISP, which is going to solve every mapping and tunneling/transport problem in the entire networking world (including mobility and security). There is SDN, which is going to solve everything by pushing it all into a controller.

And now there is BGP, which can be a link state protocol (LSVR), the ideal DC fabric control plane, the ideal interdomain protocol, the ideal IGP … a sort-of distributed god object that solves everything, everywhere, all the time (life in the fast lane…).

The problem is, a bunch of people Continue reading

Understanding the Network Impact of SASE

While SASE seemingly negates the importance of on-premises security tools, it’s likely that most enterprise organizations will still require them as part of a hybrid cloud security architecture.

The Week in Internet News: Backlash after WhatsApp Plan to Share Data

Don’t share me: After WhatsApp announced plans to share user data with owner Facebook, many users have started to move on to other secure messaging apps, the Independent reports. Rival Telegram reported a 500 percent increase in new users after the change was announced. Meanwhile, WhatsApp and Facebook are launching advertising in an effort to keep users, with the companies taking out full-page advertisements in 10 Indian newspapers, Reuters says. India is WhatsApp’s largest market, with 400 million users.

Defending the ban hammer: Twitter CEO Jack Dorsey has defended the company’s decision to permanently ban outgoing U.S. President Donald Trump, after Trump supports attacked the U.S. Capitol, the BBC says. The decision was difficult, however, Dorsey said. “I do not celebrate or feel pride,” he tweeted. “After a clear warning we’d take this action, we made a decision with the best information we had based on threats to physical safety both on and off Twitter.”

Parler goes to court: In related news, Amazon Web Services ended its web hosting arrangement with right-wing Twitter competitor Parler after the Capitol riots, effectively shutting the microblogging site down. AWS pointed to a series of posts on Parler threatening violence, including Continue reading

Network training 2021: Businesses grow their own IT expertise to meet new challenges

As the traditional approach to networking is replaced by hybrid cloud, SD-WAN and edge networks, in-house skill sets haven't kept up.Hiring new staff is one option to narrow the deficit, but there's a skills shortage in the industry right now, and hiring is expensive. According to McKinsey, it often costs around $30,000 to bring on a new employee, not counting the onboarding training. As a result, 82% of global executives surveyed by McKinsey say that reskilling and upskilling will be at least half the solution to their skills gaps.To read this article in full, please click here

Build Virtual Lab Topology: Dual Stack Addressing, ArcOS and Junos Support

In mid-December I announced a set of tools that will help you build Vagrant-based remote labs much faster than writing Vagrantfiles and Ansible inventories by hand.

In early January I received a nice surprise: Dave Thelen not only decided to use the tool, he submitted a pull request with full-blown (and correctly implemented) ArcOS support. A few days later I managed to figure out what needs to be configured on vSRX to make it work, added Junos support, and thus increased the number of supported platforms to six (spanning five different operating systems).
