Tuesday’s Amazon S3 outage reverberated around the Internet, but cost and complexity will likely keep many users from scrambling to change their redundancy practices. One of the largest service disruptions to hit AWS in years would have had far less impact if customers added more redundancy safeguards, but many cloud customers are only willing to go so far to keep their workloads running seamlessly. Companies can implement myriad contingencies to safeguard against massive cloud outages. AWS added Cross-Region Replication in 2015; IT shops also can rely on a range of disaster recovery as a service tools on the market. There also are techniques to spread workloads across regions and to back them up in other public clouds or on-premises. Netflix, which as recently as last year said it used U.S. East-1, champions several of these techniques and reported no issues Tuesday.
