Jaikumar Vijayan covers data security and privacy issues, financial services security and e-voting for Computerworld. "They are two equally important questions and whichever is more important will depend on the organization," he said. However, it would be a mistake to treat reliability and security as two separate issues, he said. "Any service is prone to outage, and you need to determine your reliability requirements and plan to meet them." "I've always advised clients that you can't count on the cloud just because it's the cloud," he said. "I do think this outage may result in more organizations realizing that the cloud isn't perfectly reliable," said Rich Mogull, an analyst with Securosis. It is still a bigger "inhibitor of adoption" compared to any other factors, he said. That is unlikely to change, for sometime, he said. Forrester's clients have consistently rated security as their top concern with cloud computing, ahead of other issues such as performance and availability, he said. Over the longer term the thornier issue for most companies will continue to be data security, he said. Ultimately though, enterprises need to realize that there can never be 100% uptime in a cloud environment, just as there can never been continuous availability within an enterprise data center, he said.įailures of the sort that happened last week will happen again, and it's up to enterprises to ensure that they have measures in place to mitigate any resulting service disruptions, he said. Last week's Amazon outage is sure to stoke enterprise anxiety about cloud performance and uptime, security is still going to be the bigger worry for most enterprises, he said.Ĭompanies that are looking to move applications to a hosted cloud environment are going to want even more availability assurances from their vendor now, he said. Such issues have consistently ranked as the top concerns for companies looking to move to hosted cloud environments.ĭon't expect that to change any time soon, said Jonathan Penn, an analyst with Forrester Research. In most cases, cloud security concerns are related to issues such as the accidental release of protected data, user authentication and access control, and the level of access that that a cloud provider might have to an enterprise's systems and data. "Enterprises I speak to are more concerned about security than they are about availability, reliability, or performance." "I still consider it to be the bigger, long-term concern," Hilgendorf said. Security is really the more pressing concern, he added.
