Why Enterprises Are Moving Toward Hybrid Cloud
Cloud computing has fundamentally changed how enterprises plan and operate their IT infrastructure. The shift began with Software-as-a-Service (SaaS) adoption and has since extended deep into the data center, where hybrid cloud architectures are now a dominant strategic direction.
According to an Evaluator Group survey of enterprise IT administrators, 62% of respondents indicated that a hybrid cloud infrastructure is part of their long-term strategy, while 58% planned to increase their hybrid cloud workload. These figures reflect a clear industry-wide trend: enterprises are no longer choosing between on-premises and public cloud, but integrating both.
John Webster, a senior partner at Evaluator Group, defines hybrid cloud as an IT architecture that integrates on-premises computing resources with off-premises public cloud resources — a definition he explicitly extends to include multi-cloud architectures.
Key Hybrid Cloud Use Cases
Disaster Recovery
Disaster recovery (DR) is the most widely cited hybrid cloud use case among traditional enterprise users, with Webster noting that upwards of 80% of survey respondents identified it as a driver. Hybrid architectures make it possible to spin up DR sites on demand, removing two of the biggest historical barriers: cost and resource availability.
“DR has long been a lagging capability because of cost, complexity and availability of resources,” Webster explains. “Hybrid cloud removes some of those barriers to adoption.”
Data Archiving
Archiving inactive data to the cloud reduces the storage burden and cost of maintaining that data on-premises. This is a relatively straightforward use case that offers immediate, measurable cost benefits with relatively low operational complexity.
Cross-Platform Application Development
Development teams can rapidly provision cloud-based environments without straining on-premises infrastructure. This elasticity accelerates development cycles and reduces the capital expenditure associated with maintaining dedicated development hardware.
Cloud Bursting
Cloud bursting allows applications experiencing peak load conditions to overflow into public cloud resources on demand, returning to on-premises capacity once load subsides. While the concept is appealing, Webster cautions that the practical benefits are harder to realize due to the architectural and networking complexity involved.
Application Geo-Distribution
An emerging use case is placing application instances across multiple geographic regions to reduce latency for end users. “This is particularly true for enterprises with worldwide customer bases,” Webster notes. As global digital user bases grow, geo-distribution is likely to become a standard architectural requirement rather than an advanced capability.
The Long-Term Outlook: Hybrid as a Destination or a Way Station?
For most enterprises surveyed by Evaluator Group, hybrid cloud is considered a long-term end state — not a transitional phase. However, Webster acknowledges the ambiguity: for some organizations, it is a deliberate strategic destination; for others, it is a stepping stone toward full public cloud migration and eventual data center closure.
“The thinking at the moment among many enterprise users is that there will always be some percentage of their applications that will remain on-premises and will therefore be ‘hybridized’,” Webster notes. “However, that assumes that the degree of difficulty in supporting [applications] is manageable and the costs for doing so are reasonable.”
Webster also points out that as public cloud providers continue to expand their service depth and breadth — often at a lower effective cost than running equivalent capabilities on-premises — the all-in public cloud option becomes increasingly viable. Staffing costs, in particular, are a hidden factor: maintaining skilled on-premises engineering teams is expensive and increasingly difficult.
Implementation Challenges and Available Solutions
Enterprises adopting hybrid cloud face a real learning curve. The technology landscape, while improving, still presents significant complexity.
- OpenStack has been widely discussed as a platform for private cloud infrastructure, but Webster observes that it “has a high degree of difficulty and has not fared well in the traditional enterprise.”
- Integrated as-a-service solutions such as Microsoft Azure Stack and VMware Cloud on AWS lower the operational complexity by packaging the integration layer, but at the time of the original reporting, these were relatively new and lacked a long track record in production environments.
Webster’s advice for potential adopters is to conduct a comprehensive cost/benefit analysis before committing to any specific platform or architecture — particularly given how rapidly the tooling landscape is evolving.
What Enterprises Actually Think About Multi-Cloud
One of Webster’s key observations is that enterprise IT decision-makers tend to think pragmatically rather than definitionally. They care less about whether their environment technically qualifies as “hybrid cloud” by a vendor’s definition and more about whether they are using public cloud as an effective tool integrated into their development and operations workflows.
“Enterprise users tend to think in terms of multi-cloud IT environments. They don’t care much for definitions — like whether or not what they’re actually doing is hybrid cloud — in spite of the fact that the vast majority of them now see the public cloud as a tool well worth exploiting and integrating into their development and operational environments.”

Key Takeaways for DevOps and Infrastructure Teams
- Hybrid cloud is now a mainstream strategy, not an experimental approach.
- Disaster recovery remains the strongest near-term driver for hybrid adoption.
- Archiving and dev/test environments offer quick, lower-risk wins for teams exploring hybrid architectures.
- Cloud bursting is technically promising but operationally complex — approach with caution.
- Geo-distribution of applications is an emerging pattern with growing relevance for global services.
- Conduct a thorough cost/benefit analysis before selecting a hybrid platform, paying close attention to staffing and operational costs, not just infrastructure pricing.
- The hybrid end state may be temporary for many organizations as public cloud capabilities continue to mature.
