The Australian Government Information Management Office (AGIMO) believes that last week's Amazon cloud outage has vindicated its initial concerns over the security and stability of cloud for government use.
The Amazon Web Service's outage struck the company's Elastic Compute Cloud (EC2) in the early hours of Thursday morning last week, taking down the services of sites including Quora and Reddit.
"The Amazon cloud outage reinforces the risks identified by the Australian Government's Cloud Computing Strategy," AGIMO told ZDNet Australia in a statement.
Risks outlined by AGIMO in its January draft cloud computing strategy included a possible loss of control of data stored in the cloud, and the possibility of a data breach in the public cloud.
After releasing the draft strategy, AGIMO came under fire from the Australian Information Industry Association (AIIA) for being overly cautious.
"The draft paper provides good background, and is informative and educative as far as it goes. In short, however, industry considers the paper overplays the risk of cloud computing," AIIA's Cloud Computing Taskforce said in its response.
"Over-emphasising data sovereignty and possible loss of control will play to agencies not wanting to change the status quo, and this may compromise higher level aims to reduce costs and increase efficiencies across government service delivery and ICT use," the taskforce added.
Despite the AIIA's warnings, AGIMO felt that its concerns were warranted as it released the finalised strategy.
"There was also some concern that the strategy put forward was too slow or too conservative. We consider that the strategy is appropriate given the risks to privacy and security of holding sensitive information in the public cloud," said government CIO Ann Steward.
AGIMO, while unsurprised over the outage, feels that vendors ought to communicate more openly with customers when experiencing service difficulties.
"Vendor transparency is important before during and after outages. The Strategy recommends that agencies consider aspects of service provision when examining a cloud procurement," AGIMO said.
