鈥淭hese strikes have caused structural damage, disrupted power delivery to our infrastructure, and in some cases required fire suppression activities that resulted in additional water damage,鈥� AWS said in an update on its online dashboard.

It said by late Tuesday that recovery efforts at the UAE data centers were making progress.

Unlike AWS involving software that resulted in widespread global outages, these attacks involving physical damage appear to have resulted only in localized and limited disruption.

Amazon Web Services hosts many of the world鈥檚 most-used online services, providing behind-the-scenes cloud computing infrastructure to many government departments, universities and businesses.

The company advised customers using servers in the Middle East to migrate to other regions, and direct online traffic away from the UAE and Bahrain.

鈥淎mazon has generally configured its services so that the loss of a single data center would be relatively unimportant to its operations,鈥� said Mike Chapple, an IT professor at the University of Notre Dame鈥檚 Mendoza College of Business.

Other data centers in the same zone can take over, and most of the time this happens seamlessly every day to balance workloads, he said.

鈥淭hat said, the loss of multiple data centers within an availability zone could cause serious issues, as things could reach a point where there simply isn鈥檛 enough remaining capacity to handle all the work.鈥�

Amazon doesn鈥檛 typically disclose the exact number of data centers it operates around the world.

It says only that its data centers are clustered in 39 geographic regions, with three such regions in the Middle East, covering the United Arab Emirates, Bahrain and Israel.

Each AWS region is split up into at least three data center availability zones, with each zone isolated and physically separated 鈥渂y a meaningful distance,鈥� although they are all within 100 kilometers (60 miles) of each other and connected by "ultra-low-latency networks鈥� that reduce the time lag for data transmission.

AWS says its data centers have redundant water, power, telecom, and internet connections 鈥渟o we can maintain continuous operations in an emergency.鈥�

They also have physical security, but those measures, including security guards, fences, video surveillance and alarm systems, are designed to keep out intruders rather than defend against missile attacks.

Chapple said the attacks are a reminder that cloud computing isn鈥檛 鈥渕agical鈥� and 鈥渟till requires physical facilities on the ground, which are vulnerable to all sorts of disaster scenarios.鈥�

Data centers run by AWS and other operators are massive facilities that are hard to hide, he added.

鈥淥rganizations using services from any cloud provider in the Middle East should immediately take steps to shift their computing to other regions,鈥� Chapple said.
