After many repetitive outage of cloud computing, many people considers Business Continuity on Cloud Computing and think about realities of SLA.

 

CIO.IN: Do Amazon’s Customers Share Responsibility for its Frequent Outages?

Verbatim:

Organizations Must Treat Cloud Providers as a Utility […] If you’re a corporation and you have a building, you have a diesel generator in the basement in case the electricity goes out […] You have two telco lines coming in so if you lose one, you still have communications. Cloud is the same thing. It’s a utility. Have two.

Putting all your eggs in one basket is clearly a good and bad strategy, good because you get to be a big customer of a provider, you get economies of scale, better pricing, someone should pick the phone up when you call etc. etc.,” Currill says. “Bad because you give away some control, when AWS went down for many infrastructure teams at customer sites who may have engineered their application to be redundant inside their host, clearly what they didn’t take into account was the unthinkable-what happens if the host goes down?

ZDNet: Business Discontinuity: Poorly communicating Cloud outages

Verbatim:

Thus, we would expect that the communication that follows an outage from a Facebook, or Twitter to be less detailed than those from an Amazon or Salesforce.com. This is because for companies like Amazon and Salesforce.com, they would need to explain why they missed a Service Level Agreement with their customers.

The Cloud is made up of a multitude of complex systems, software and hardware, and there is no reason to think that these would fail more or less than say a non-cloud datacenter.
