EHR applications have dramatically changed healthcare for providers and patients, alike. EHR-related services now extend well beyond collecting patient data to delivering decision support for evidenced-based care initiatives that advance disease-management processes. Accessibility of these rich data-enabled services has raised the need for a higher level of performance and availability across the healthcare datacenter. Those greater demands have resulted in added complexity and continually rising costs. Yet, without reliable 24x7x365 performance, clinicians and others quickly lose confidence in these high-potential initiatives, and utilization suffers.
