NASA eclipse streaming in the cloud

For the total solar eclipse that will cross the country on Aug. 21, Americans have spent the last few weeks tracking down protective glasses and scouting out good viewing locations. NASA, on the other hand, has spent the last three years preparing for up to a billion users to stream the eclipse through NASA TV.

Through NASA’s Web Enterprise Service Technology Contract, InfoZen is responsible for streaming the event on NASA TV, which is available from the agency’s website. 

With the eclipse being monitored worldwide, InfoZen is making sure the infrastructure is up to the task. 

“We have architected a solution for the eclipse to use the most robust cloud services and other infrastructure that might come into play with streaming,” Sandeep Shilawat, Infozen’s cloud program manager, told GCN. “We have a list of vendor partners [who are] coming up with a backup plan for the backup for the backup.”

The space agency's 13 NASA TV streams are hosted through AWS S3, which allows NASA to “segregate” the stream for the eclipse and apply “multiple mechanics,” including auto-scaling caches and time delivery.

Viewing estimates for the solar eclipse depend on a variety of factors, including weather and cloud cover. NASA is prepping its website to be able to handle up to a billion viewers just in case more people than expected are not able to physically view the eclipse in person.

“Because of how important this event is and the demand worldwide, we are treating this like a NASA launch,” said Steve Penyak, senior vice president of IT modernization at InfoZen. “It doesn’t compare to launching a rocket ship, but with the preparations, planning and looking into contingency plans, we are treating this similarly in terms of choreographing how it is going to be done.”

According to NASA, the solar eclipse will begin at 9:05 am PDT in Lincoln Beach, Ore., and the lunar shadow will leave the United States at 4:09 EDT. More information from NASA on the solar eclipse can be found here.
