Submarine cables: The true backbone of the Internet (video documentary!)

Did you know that less than 1% of the global Internet traffic is transmitted via satellites? The actual workhorses are 1.1 million kilometers of submarine cables that lay on the bottom of the ocean floor. More than 400 of these cables connect the continents and make the Internet a really global thing. But how did they get there and how do they survive?

The End of Cloud Computing…

Be prepared to have your mind blown in 25 minutes… Peter’s key statement: “The entire world becomes the domain of IT.” In the next 10 years trillions of cheap sensors&cpus (inside almost everything that has some value) will shift computing power to the edge that will dwarf today’s cloud. And suddenly the IT people will not only run the world from the cloud, but the whole world itself.
How can we say cloud computing is coming to an “end” when it hasn’t even really started yet?? Because the edge — where self-driving cars and drones are really data centers with wheels or wings — is where it’s at. So where does machine learning in the enterprise come in? How does this change IT? As software programs the world, these are some of the shifts to look at…

BYOD is not your enemy. It’s the future. Make “BYOD First” your strategy for 2017!

There are no sacred cows to someone who believes that consumer devices and self-service IT are the keystones of the new business office world. One of these cows is wired Ethernet in the workplace. It will largely go away soon!

Here is an extreme example: Last August Microsoft announced that they are ditching copper-based Ethernet in 660 campuses in favor of WiFi-only offices over the next 24 months.

“Our users don’t simply use a workstation at a desk to do their jobs anymore. They’re using their phone, their tablet, their laptop and their desktop computer, if they have one,” said Lef in a Q&A published in the Microsoft Azure Blog. “It’s evolved into a devices ecosystem rather than a single productivity device, and most of those devices support wireless. In fact, most of them support only wireless.”

David Lef, principal network architect at Microsoft IT.

Sensors vs. Monitors vs. Probes vs. Checks

Comparing the terminologies of PRTG, WhatsUp, OpManager and SAM

Almost 20 years ago when I started my monitoring software company and wrote the first monitoring code (for “IPCheck” as it was called back then) I decided to use the word “sensor” as the name for the most basic monitoring item and the “probe” would be thing that gathered the data.

At about the same time people at Ipswitch, Solarwinds and ManageEngine had to make similar decisions, but they made different naming decisions that differenciate us to this day.

Things that keep us from reaching 100% uptime: Power Grid Outages

The mission of our company is to build products and services to help system administrators reach 100% uptime for their networks. We all know that it becomes harder and harder to reach 100% the closer you come to your goal, it’s like trying to reach the speed of light.

One of the limitations that system administrators can’t do much about is the reliability (or failure rate) of the electrical power grids they have to rely on. In a data center it is pretty easy to get around this problem by installing uninterruptible power supplies (ups): using a generator you can run a data center off-the-grid for days.

But what about the on-site networks that you serve with that data-center, the people in the offices and factory buildings. Your ups won’t help. When the power grid fails, your computer-using colleagues will twiddle their thumbs until power is coming back again.
