My latest article for AITS was published today: Redundancy: You Can Say That Again!
This past summer, there were two very high-profile system outages at Delta Airlines and Southwest Airlines that underscored the need to design for survivability and availability at the enterprise level. This article starts with the “punch lines” from each incident and then explains the role of redundant components and services in the modern data center. I then go on to review best practices in testing and close by bringing up the Cloud as an alternative to the one-size-fits-all corporate data center, especially now that different availability service levels can be acquired as needed for each application.
As always, thanks for taking the time to read my stuff.
