The results of a new research study, conducted by and issued today by Cisco Internet Business Solutions Group (IBSG), investigates the “public cloud” and the desire of enterprises to use external, on-demand infrastructure and applications. The study reveals that service providers have an opportunity to differentiate themselves and add new revenue-generating services by providing public cloud-computing services.
Cisco IBSG, the company’s global consultancy, recently conducted in-depth, one-on-one interviews with more than 80 enterprise information technology (IT) decision makers from 43 enterprises and public-sector organizations in the United States, the European Union, and India. Additionally, Cisco IBSG interviewed 20 subject-matter experts.
Based on feedback from the survey, Cisco IBSG estimates that nearly 12 percent of enterprise workloads will run in the public cloud by the end of 2013. Furthermore, the study found that desktop applications, email, collaboration, and enterprise resources planning are most likely to shift to the cloud. This, in turn, will yield a market for public, cloud-computing services of approximately US$44 billion.
The study identified a set of target applications for cloud that spans various verticals. Targets for infrastructure-as-a-service (IaaS) include application development and testing, disaster recovery, simulations, data warehousing, and analysis. Targets for software-as-a-service (SaaS) are customer-relationship management (CRM), email, unified communications, web applications and desktop environments.
Cloud-migration decisions are being made at the application level. Most decision makers envision a staged migration to cloud-computing services, beginning with noncritical applications. Enterprise executives believe that no applications should be automatically excluded from migration to cloud.
