Introduction

In the Laboratory Information System market, the term “cloud-based” is frequently used but rarely defined.

Cloud-hosted software and web-native SaaS platforms represent fundamentally different architectural approaches.

For lab leaders evaluating LIS vendors in 2026, understanding this difference prevents costly assumptions.

What “Cloud-Based” Often Means

A cloud-based LIS may:

  • Be installed on remote infrastructure
  • Run within virtual machines
  • Require VPN or remote desktop access
  • Maintain environment-specific upgrades
  • Depend on manual patch cycles

While hosted remotely, the application itself may not be architecturally modern.

What Web-Native Means

A web-native LIS:

  • Is built for browser execution
  • Requires no remote desktop layers
  • Deploys centrally
  • Updates automatically
  • Scales horizontally
  • Integrates through modern APIs

Web-native design enables greater flexibility in:

  • Remote case review
  • Multi-site operations
  • Digital pathology adoption
  • AI workflow implementation

Operational Implications for Labs

Update Management

Cloud-hosted: Coordinated downtime
Web-native: Seamless updates

Scalability

Cloud-hosted: Additional virtual resources
Web-native: Elastic architecture

Security

Cloud-hosted: Shared responsibility
Web-native: Centralized governance

Interoperability

Cloud-hosted: Custom integration layers
Web-native: Standardized APIs

Why This Matters in Vendor Selection

Many LIS vendors describe their systems as “cloud,” but architecture varies significantly.

Understanding the difference between cloud-hosted and web-native systems ensures labs align their technology with long-term growth.
