However, there's a growing sense that things may be more secure in the public cloud, especially since cloud providers pay a lot of attention to it, and make it their business to keep up with the latest security technology.
That's the gist of a recent survey of 210 IT executives conducted by SADA Systems. SADA specializes in cloud migrations, so it's to be expected they would want to demonstrate that cloud security fears are waning. But this is a trend that has been evolving in recent years, with an awareness that things are getting so complex, and the external and internal security threats are getting so savage, that it's just too much for a corporate IT shop to attempt to do on its own.
The survey's key takeaway was that IT managers are more confident in the security and reliability of the public cloud than they used to be, and as a result they are running more data and applications on public cloud infrastructure. The survey found that 51% said data security is better in the cloud than in their own data centers, and 58% said the public cloud was the most secure, flexible and cost-effective solution for their organizations. In addition, 13% said they "trusted public cloud providers more than their internal teams" to handle data and applications.
Other issues affecting public cloud adoption focus on control, or the loss thereof. At least 40% of IT executives said they were hesitant to move to public cloud services due to concerns about stability and the public cloud's long-term viability. If a cloud service provider began to hit a financial slump, 34% would back away from that vendor. Another one-third were concerned about costs escalating beyond their control.
The survey also finds that 84% of respondents are using public cloud infrastructure today, led by Google Cloud Platform, Microsoft Azure and Amazon Web Services. Migrations to any public cloud provider typically take three to six months to accomplish (indicated by 45%), and 23% said it took less than three months.
