Four Barriers Limiting Healthcare Cloud Efficiency

How cloud leaders address structural constraints

Cloud adoption in healthcare has accelerated in recent years, driven by the need for flexibility, scalability and better access to data. Many organizations have made meaningful progress, yet operational and financial outcomes remain inconsistent. The gap reflects a set of structural barriers that shape how cloud performs in practice, not just differences in investment.

The 2026 Rackspace Healthcare Cloud Report identifies four constraints that consistently influence outcomes:

1. Legacy infrastructure
2. Cost complexity
3. Security and compliance requirements
4. Skills gaps

These barriers tend to show up early, often starting with the systems organizations rely on most.

Legacy infrastructure limits modernization

Legacy systems continue to shape cloud outcomes across healthcare. Many organizations still depend on technologies that were not designed for interoperability, scalability or current data demands.

The impact is widespread. Sixty-three percent of healthcare organizations report relying on legacy systems to a moderate or high degree, and 75% say these systems limit their ability to modernize IT environments.

These constraints affect core operations:

• Data integration and interoperability
• Electronic health record (EHR) performance
• Revenue cycle and billing systems

As a result, data remains fragmented, workflows slow and system performance becomes harder to optimize.

How leaders address infrastructure limits

Cloud leaders integrate modernization into their cloud strategy. In practice, this means they focus on:

• Refactoring or replacing legacy applications
• Introducing interoperable platforms
• Rationalizing data and application environments

These actions help reduce dependency on outdated systems. Only 10% of cloud leaders report that legacy infrastructure significantly limits modernization efforts, compared to 44% of less mature organizations.

Reducing technical debt supports faster data movement, more reliable system performance and improved operational efficiency.

Unpredictable costs limit cloud efficiency

Cloud introduces a different cost model that requires active management. While it can reduce capital expenditure and improve flexibility, it also creates variability that many organizations are not prepared to control.

The report shows a divided experience:

• 59% of organizations say cloud costs meet or fall below expectations
• 40% report higher-than-expected costs and lower-than-anticipated savings

These outcomes often depend on how environments are designed and managed. Organizations that move workloads without architectural changes carry inefficiencies forward, while limited governance increases cost variability.

How leaders address cost complexity

Cloud leaders apply structured financial management practices that support ongoing optimization. Key practices include:

• Monitoring usage and costs continuously
• Aligning workloads to the most efficient environments
• Using hybrid models to balance performance and spend

They also evaluate cost alongside performance. Improvements in system efficiency and reductions in operational overhead contribute directly to overall value.

Security and compliance shape architecture decisions

Security and compliance requirements play a central role in healthcare cloud strategy. The sensitivity of patient data and regulatory expectations require consistent control across environments.

More than half of healthcare organizations cite data security and compliance as primary drivers of workload movement between environments.

This often results in fragmented architectures, increased operational overhead and slower progress toward optimization.

How leaders address security and compliance requirements

Cloud leaders incorporate security into how environments are designed and operated. They:

• Build secure and compliant architectures from the outset
• Apply governance frameworks that support consistency
• Use advanced controls and monitoring to manage risk

This integrated approach allows organizations to maintain control while improving performance and operational efficiency.

Skills gaps slow execution

Cloud and AI initiatives depend on the ability to design, operate and optimize complex environments. In healthcare, limited access to specialized expertise continues to constrain progress.

The report highlights:

• 29% of organizations cite lack of in-house expertise as their biggest challenge in modernizing EHR environments
• 34% identify limited internal knowledge as a primary barrier to AI adoption

These gaps increase operational complexity and extend implementation timelines.

How leaders address skills gaps

Cloud leaders build capability through a combination of internal development and external support, such as:

• Investing in targeted hiring and upskilling
• Working with experienced providers
• Using managed services to extend internal teams

This model supports more consistent execution, reduces risk and accelerates time to value.

From constraints to operational efficiency

Each of these barriers introduces friction. Together, they shape how effectively cloud environments support the organization.

Cloud leaders take a coordinated approach. This includes:

• Addressing constraints as part of a unified strategy
• Aligning cloud initiatives with business priorities
• Investing in modernization, governance and skills development in parallel

This allows them to move from reactive issue management to continuous optimization.

The path forward

For healthcare and IT leaders, improving cloud outcomes requires addressing the conditions that limit efficiency.

Key priorities include:

• Reducing reliance on legacy systems
• Applying financial discipline to cloud operations
• Embedding security into architecture and governance
• Building or accessing the expertise needed to sustain progress

Organizations that take this approach position themselves to translate cloud adoption into measurable operational advantage.

In a sector where efficiency affects patient care, cost management and workforce sustainability, these changes have direct impact across the organization.
