Clouds and cables: a pair of useful websites

Posted by riverbedtest on November 7, 2011

Occasionally I encounter fascinating websites that collect lots of neat data and present it in useful ways. I'd like to share a couple of my favorites with you this morning. And yes, they both relate to the topic of computer networking!

CloudSleuth: analyze cloud performance, produced by CompuWare (and with whom we partner), provides a application that displays near real-time cloud performance metrics. The Global Provider View displays the results of measuring a sample application running on multiple public clouds. You can choose response time or availability metrics, a time window between six hours and 30 days, and four separate geographic areas (or the whole world). You can navigate through a map with clickable city nodes, a line chart that graphs the last six hours, or a table listing the raw data. You can narrow the view to specific providers and cities. Scroll the page down to read a thorough description of the measurement methodology, including the design of the sample application.

Greg's Cable Map: explore the undersea backbone

Cablemap2-smWhen I first discovered this site, a couple hours of my day flew by đŸ™‚ Greg's Cable Map mashes data from Wikipedia, fishermen's charts, marketing materials, and other sources onto a Google map of the world to reveal the millions of kilometers of telecommunications cables that ring the planet. When you hover over a cable, a box at the bottom of the browser window displays the cable's name, number of landings, length, and bandwidth. When you click the cable, additional data appears to the right, including in-service date and landing locations. There are some truly curious entries: for example, a 5 Tbps cable between Svalbard and Norway! Why so much bandwidth in such a remote place? Polar orbiters have to dump their data somewhere.

Your favorites

Do you have some favorite data visualization websites? Feel free to share in the comments. We seven billion Earthlings are awash in data; visual displays can help us to interpret it better, reveal otherwise subtle yet important trends, and make the information more interesting

    Can they be affected by earthquakes or a sea volcanic eruption?

    Telegeography has a great commercial mapping service for undersea maps
