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?
Did you know…
- that 50% of the 7.5 billion people on earth are Internet users (annual growth 10%)
- that >85% of the people in North America and Europe are Internet users
- that 66% of the 7.5 billion people on earth are mobile phone users, and each one of them has 1.6 SIM cards/contracts on average (8 billion, more SIM cards than people on earth)
- that 45% of global web traffic comes from laptops & desktop (down by 20% from last year)
- that 50% of global web traffic comes from mobile phones (up by 30%)
- that 37% of the global population are social media users and 55% of them check in every day
- that an average smartphone uses 1.9 GB of data per month (globally!)
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.”

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.
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.
