Microsoft takes ExpressRoute to orbit to sling Azure services at backwaters via satellite

Your planet is one of those scheduled for demolition, er, we mean Redmond pals up with SES, Intelsat and Viasat


Updated Microsoft has buddied up with a trio of satellite operators to hook up its Azure cloud to locations lacking connectivity.

ExpressRoute is aimed at extending an on-premises network into Microsoft's cloud via a private connection courtesy of a connection provider. Rather than the public internet, express routes keep things private and so are, in theory, a tad more reliable and secure than is typical.

Of course, in a remote or isolated location where there may not be a handy access point, things are a little trickier. Getting the data into the cloud from sensors springing up on farms, mines and servers lurking in hard-to-access places is a challenge.

To that end, Microsoft has added satellite connectivity into the mix, courtesy of new best friends SES, Intelsat and Viasat.

SES told The Register that its multi-orbit service, comprising geostationary and medium Earth orbit satellites, would give ExpressRoute customers "fibre-like" performance and global coverage.

Sadly, the company was not so forthcoming when it came to actually putting a figure on the speed and latency a customer might expect when connected to Azure via a space-borne ExpressRoute link.

Intelsat and Viasat did not immediately respond to our requests for more information.

Still, with Microsoft CEO Satya Nadella showing no signs of following Amazon CEO Jeff Bezos into space, leveraging someone else's satellites makes sense.

Naturally, ExpressRoute is not the only game in town. Amazon's Direct Connect and Google's Dedicated Interconnect also allow a customer high- speed dedicated connectivity to each giants' data centres. Microsoft's step just simplifies things a little for Azure customers looking to plug in from somewhere with poor connectivity.

Azure is no stranger to orbital shenanigans. While everyone else was gawping at the HoloLens 2 during February's Mobile World Congress, Microsoft and Inmarsat snuck out an announcement to the effect that Azure IoT devices would be able to fling their data into the cloud via Inmarsat's network.

Again, handy for flaky connectivity.

The addition of ExpressRoute, however, ups the ante. The predicted explosive growth in commercial constellations means that there should be plenty of private bandwidth to go around.

For a price, of course. ®

While Intelsat continues to maintain a dignified silence, Viasat got in touch to boast about its bandwidth and vertically integrated network, "which we believe is the best way to get high bandwidth delivery".

The company was unable to provide any specifics but said: "We expect improvements in the ground latency and stability."

Viasat Direct Cloud Connect will hit later this year (along with pricing) and will initially be US only. The UK will get to join the party "in the future".

    In brief Thieves operating for the North Korean government made off with almost $400m in digicash last year in a concerted attack to steal and launder as much currency as they could.

    A report from blockchain biz Chainalysis found that attackers were going after investment houses and currency exchanges in a bid to purloin funds and send them back to the Glorious Leader's coffers. They then use mixing software to make masses of micropayments to new wallets, before consolidating them all again into a new account and moving the funds.

    Bitcoin used to be a top target but Ether is now the most stolen currency, say the researchers, accounting for 58 per cent of the funds filched. Bitcoin accounted for just 20 per cent, a fall of more than 50 per cent since 2019 - although part of the reason might be that they are now so valuable people are taking more care with them.

    In brief California’s Department of Motor Vehicles said it’s “revisiting” its opinion of whether Tesla’s so-called Full Self-Driving feature needs more oversight after a series of videos demonstrate how the technology can be dangerous.

    “Recent software updates, videos showing dangerous use of that technology, open investigations by the National Highway Traffic Safety Administration, and the opinions of other experts in this space,” have made the DMV think twice about Tesla, according to a letter sent to California’s Senator Lena Gonzalez (D-Long Beach), chair of the Senate’s transportation committee, and first reported by the LA Times.

    Tesla isn’t required to report the number of crashes to California’s DMV unlike other self-driving car companies like Waymo or Cruise because it operates at lower levels of autonomy and requires human supervision. But that may change after videos like drivers having to take over to avoid accidentally swerving into pedestrians crossing the road or failing to detect a truck in the middle of the road continue circulating.

  • Alien life on Super-Earth can survive longer than us due to long-lasting protection from cosmic rays

    Laser experiments show their magnetic fields shielding their surfaces from radiation last longer

    Life on Super-Earths may have more time to develop and evolve, thanks to their long-lasting magnetic fields protecting them against harmful cosmic rays, according to new research published in Science.

    Space is a hazardous environment. Streams of charged particles traveling at very close to the speed of light, ejected from stars and distant galaxies, bombard planets. The intense radiation can strip atmospheres and cause oceans on planetary surfaces to dry up over time, leaving them arid and incapable of supporting habitable life. Cosmic rays, however, are deflected away from Earth, however, since it’s shielded by its magnetic field.

    Now, a team of researchers led by the Lawrence Livermore National Laboratory (LLNL) believe that Super-Earths - planets that are more massive than Earth but less than Neptune - may have magnetic fields too. Their defensive bubbles, in fact, are estimated to stay intact for longer than the one around Earth, meaning life on their surfaces will have more time to develop and survive.
