Amazon outage 'proves cloud can work'

Amazon's recent outage of its cloud service has proved that its method of data storage was suitable for purpose.

This is according to James Burchill, who, writing in Technorati, explained that the failure of Amazon's cloud service, known as AWS, proved that the design for failure (DFF) system works well, if applied correctly.

He explained that the provider has learnt a valuable lesson from the April downtime, gaining the "opportunity to rebuild their system to be more fail-proof".

The system was a hybrid of the DFF cloud model and the traditional idea of spreading resources within a relatively small geographic area.

This can be problematic if there is an area-wide failure, so Amazon's attempts to diversify at least to some extent helped reduce the impact of failure.

DFF involves spreading availability to a mixture of software management and physical design, allowing for failures of single or multiple parts of the cloud to occur without the destruction of applications and data.

Mr Burchill explained that the best DFF systems involve spreading data between multiple locations and mirroring in multiple locations geographically.
