Amazon is the dominant player in cloud computing, with its Amazon Web Services (AWS) having 45 percent market share, crushing the competition, most notably, Google and Microsoft. Yesterday, AWS experienced major outage, that lasted for several hours. The outage was mostly isolated to AWS's one U.S. region, dubbed as us-east-1 region. Despite the limited geographical scale, the services that relied only on that AWS datacenter, were hit badly. Some of the largest services that were deeply hit included Adobe 's cloud services and Roku streaming services. Amazon's biggest clients, such as Apple and Netflix, didn't experience outages - probably because they use several different AWS datacenters and were able to re-route their traffic to other locations. Most interesting outcomes of the outage were experienced by users who had adopted various smart, connected home appliances. For example, Roomba robotic vacuums stopped working through the iRobot Home app.
