Two years ago, in our 2015 Cloud User Survey, Stratecast asked IT decision-makers to identify their company’s “primary” deployment model for a series of business applications. Our goal was to track responses, over time, to identify trends: for example, is a consensus emerging regarding the optimal deployment model for a particular workload? Which workloads are being assessed and moved first? How quickly are organizations implementing their hybrid IT strategies? In this report, we revisit these questions, with responses from our 2017 survey. Key Highlights: --Growth Across All Deployment Models --Definitions of Application Deployment Environments and Architectures --Utilizing Multiple Deployment Models --Current and Planned Adoption of Deployment Models --Tracking Growth Across All Environments --Expected Usage Increase/Decrease over Next 2 Years, by Cloud Model --Expected Increase/Decrease in Usage over Next 2 Years, by Enterprise-Managed Deployment Model --Expected Increase/Decrease in Usage over Next 2 Years, by Managed Service Deployment Model --Which Applications are Where? Top Apps per Deployment Model --Top Cloud Workloads, by Deployment Model --Top Enterprise-Managed Workloads, by Deployment Model --Hybrid Workloads --Top Applications Split across Two or more Deployment Models --The Last Word
