Amazon Web Services (AWS) has recently been attacked by DDoS and forced to interrupt service. The downtime lasted for eight hours. Amazon’s announcement showed that “Between 10:30 AM and 6:30 PM PDT, we experienced intermittent errors with resolution of some AWS DNS names. Beginning at 5:16 PM, a very small number of specific DNS names experienced a higher error rate. These issues have been resolved.” During this period, hackers attacked the company’s Router 53 DNS Web service, causing intermittent errors in its DNS and including Elastic Load Balancing (ELB), Relational Database Service (RDS), and Elastic Compute Cloud (EC2).
The data shows that AWS is the world’s largest cloud service provider. As of the fourth quarter of 2018, AWS’s cloud market share has reached 32%. The second-ranked Microsoft Azure has a 16% share. Google Cloud’s market share is 9%, ranking third. Alibaba’s Alibaba Cloud ranked fourth with a market share of 4%. Although AWS’s market share is far ahead, this downtime will undoubtedly reduce the user’s trust in the platform. After the incident, AWS users expressed their dissatisfaction and publicly questioned the effectiveness of their DDoS mitigation platform Shield Advanced.
