CNN reports…
Amazon Web Services (AWS), the cloud computing platform that powers much of the internet, went down for several hours Monday, making several majorwebsites and apps inoperable.
From banking services to social networks to airline booking sites to online shopping, thousands of services were disrupted as millions of people worldwide – many of whom were on their way to work on the US East Coast – were unable to mobile-order coffee or access key apps.
The latest outage serves as a reminder of how fragile the internet’s backbone can be, even if the disruption is brief, and how reliant the world has become on these online services.
Although AWS and its competitors are generally robust, the internet is a complex web of overlapping services that are only as reliable as their weakest code. The root cause of Monday’s outage remains unknown, but a service that converts friendly web names into IP addresses was unable to communicate with thousands of companies’ massive databases hosted by Amazon.
This isn’t a first occurrence…
Past outages on this scale have been caused by a wide variety of errors, including faulty updates, the accidental injection of bad code, or a change to third-party software that doesn’t play nicely with a service. Rarely, internet cable cuts, cyberattacks or direct denial of service attacks can bring down or overload servers that host key apps.
But the relative frequency of these events shows the lack of necessary redundancies and competitive services. Too often, some internet experts say, companies put all their eggs in one cloud services basket.
NPR talks about the pros and cons of big cloud computing options…
According to Synergy Research Group, AWS holds about 30% of the worldwide cloud computing market. Other big players are Microsoft and Google.
Betsy Cooper, a cybersecurity expert and the director of the Aspen Institute’s Policy Academy, says there are pros and cons to companies using Amazon or another big provider for cloud computing. They offer strong cybersecurity protections and convenience.
“We all have an incentive to use the big companies, because they’re so ubiquitous and it’s easier for us to access all of our data in one place.”
But, she says, there’s a downside.
“That’s great until something goes wrong, and then you really see just how dependent you are on a handful of those companies.”
