Severe weather intensifies focus on disaster planning

Companies should no longer depend on only a cloud provider for backup

By , Computerworld |  Disaster Recovery

Severe thunderstorms knocked out power to 1.2 million homes in the D.C. area. Wildfires ravaged more than 2
million acres in the Rockies. Two-thirds of the country is in drought conditions, and flooding is expected to get
worse as the time between rainstorms lengthen and, in turn, grow more intense.

Intensifying weather patterns threaten businesses as global warming raises the temperatures of the oceans.
Disaster recovery plans that include only backing up data regionally may need to be rethought, experts say.

The cloud, which was supposed to guarantee high availability, has been significantly affected by power outages
caused by storms. Companies dependent on cloud service provider Amazon Web Services (AWS) found their websites down
a week ago when rare severe thunderstorms, known as derechos, struck the Virginia and Washington D.C.
area, leaving 1.2 million homes without power for days.

"We thought that by simply deploying [our website] across multiple active zones on Amazon we were going to have
the backup we needed," said Brandon Wade, CEO of WhatsYourPrice.com, an online dating site with 400,000 active
members. Wade said his site went down twice, for two hours each time after Amazon lost power. More than 1,000
customers contacted WhatsYourPrice.com to complain, he said.

WhatsYourPrice.com had initially signed on with Amazon's AWS 18 months ago because using a service provider
reduced costs for the start-up. But, after two outages at Amazon in less than a month, WhatsYourPrice.com
canceled the cloud service
, and is now deploying its servers in two co-location facilities, as well as using a
local Las Vegas cloud provider for data
backup.

"If your business can take a few hours of outage when a disaster strikes, then [Amazon AWS] is the solution to
have," Wade said. "Otherwise, you need to architect in a smarter way."

Derechos, which are caused by severe heat waves and can develop hurricane-force winds, can span hundreds of
miles. The storm on June 29 spanned some 700 miles and had average wind speeds of 60 mph.

An Amazon spokesperson said the derecho caused AWS to lose
primary and backup generator power
to a portion of a single "Availability Zone" in its US-East Region on June
29.
