IT Infrastructure Qualification - From Data Center to Cloud.
IT infrastructure qualification demonstrates that the infrastructure beneath your GxP systems is built to specification and under control - from your own data center to the cloud. The evidence is not a protocol signed on a given day, but a controlled state: established according to risk, maintained through tools and monitoring.
The foundation beneath every GxP system.
EU GMP Annex 11 puts the principle plainly - "The application should be validated; IT infrastructure should be qualified." How deeply is not prescribed: the scope follows the risk of the GxP processes the infrastructure supports - from hardware and networks through virtual environments to operating systems and databases.
A paper record with a date on it
A paper-based record confirms the state of a single day - it says little about ongoing operation.
A controlled state in operation
The qualified state is maintained within the IT quality management system: service management, automation, and monitoring carry the evidence. Build reports, the configuration management database, and monitoring logs are the records - governed by data integrity per ALCOA++.
Risk-based from need to controlled state.
Instead of a rigid phase model, every step derives from the risk of the supported GxP processes - evidence is deepened where it contributes most to safety.
- 1
Planning & risk assessment
Assessing the risk of the supported GxP processes and deriving the scope and depth of qualification - the risk-based starting point that sets the effort per component.
- 2
Requirements & specification
Capturing and documenting the infrastructure requirements, and confirming that the planned design fulfills them.
- 3
Build & verification
Documented evidence that hardware, virtual infrastructure, and infrastructure software are installed and configured to specification - automated build reports and Infrastructure as Code (IaC) deliver it reproducibly, with supplier documentation leveraged according to risk.
- 4
Acceptance & release
Functional evidence at the risk-based scope, the qualification report, and release of the infrastructure for GxP use.
- 5
Controlled state in operation
Change, configuration, and security management, patching, and periodic review maintain the state - the configuration management database (CMDB) and monitoring logs carry the evidence forward continuously.
How do you qualify what you don't own - a moving target?
Cloud infrastructure belongs to the provider and changes constantly: capacity breathes with demand, patches arrive on the provider's schedule. A point-in-time record misses the mark twice over - the answer lies in demonstrable control on three levels:
Two service models carry outsourced infrastructure - Infrastructure as a Service (IaaS) and Platform as a Service (PaaS); they differ in how far the provider's responsibility extends:
| Model | The provider carries | Your evidence focus |
|---|---|---|
| IaaS | Data center, hardware, and virtualization - operated as a controlled service, without insight into the physical environment | Qualify your own layer (operating systems, databases, middleware); verify delivered instances against the order - the provider's build reports serve as evidence |
| PaaS | Additionally operating systems, middleware, database services, and the development environment - the full application life cycle | Assess the provider's controls; keep your own applications and deployments on the platform under control |
Software as a Service is deliberately outside this picture: a rented application directly fulfills business processes and belongs to the validation of the computerized system as a whole - in its process, against its intended use.
Operating infrastructure is the core competency of the major providers; their controls are often more mature than in-house operation. What is demonstrated is controlled operation: through supplier qualification, service and quality agreements, and continuous monitoring.
Add to this compute: training and scaling modern AI models exceed company-owned data centers, and the demand arrives in bursts. Elastic compute from the cloud is what makes AI applications in the GxP environment operable in the first place - demonstrate controlled use of the cloud, and the path is open.
Risk-based scope by infrastructure component.
The qualification scope scales with component type and risk: standard components are demonstrated leanly, while configured and outsourced building blocks receive the depth of control their risk demands.
| Infrastructure component | Classification | Qualification focus (risk-based) |
|---|---|---|
| Operating systems, databases, infrastructure software | standard infrastructure software | Inventory, version, and configuration - recorded in the tooling, deliberately lean where risk is low |
| Hardware, network, servers | physical infrastructure | Acceptance against the specification; functional evidence goes as deep as the risk demands |
| Virtual infrastructure, Infrastructure as Code (IaC) | configured | The code is the specification: verified once, it provisions identically - every run documents itself in the build report |
| Cloud services (IaaS, PaaS) | outsourced operation | Control over the provider: qualification, service and quality agreements, ongoing service monitoring |
| Backup & restore, disaster recovery | process on the infrastructure | What matters is the rehearsed recovery under real operating conditions |
| Change, configuration & security management | operational process | The operational processes carry the evidence forward - they maintain the qualified state in day-to-day operation |
Does qualification end at the edge of the shop floor?
No - it follows the data. The production level (operational technology, OT) was long a world of its own: process control systems and sensors, strictly hierarchical, separated from the corporate network. That separation is dissolving:
Qualification, implemented risk-based.
From strategy to report - and beyond: we maintain the qualified state in operation.
We know the guide for this path - we helped write it.
QFINITY contributed to the GAMP Good Practice Guide "Enabling Innovation" - the guide that describes how the qualified state of modern IT infrastructure is maintained through tools, automation, and monitoring, from the company data center to IaaS and PaaS.
GAMP 5 Second Edition, which QFINITY helped shape as part of the Core Team, carries the same line: risk-based control instead of blanket documentation. Infrastructure cannot be partitioned into GxP and non-GxP - it is controlled as a whole, with uniform IT practices and evidence drawn from the tools.
Frequently asked questions on IT infrastructure in the GxP environment.
Yes. No regulation prohibits cloud operation; what is required is demonstrable control. Accountability stays with the regulated company - demonstrated through provider assessment, service and quality agreements, and continuous monitoring. Operated this way, the cloud is open to GxP-critical applications as well.
No. The DQ/IQ/OQ/PQ phase model comes from qualifying stable equipment. IT infrastructure is qualified risk-based: standard components leanly, configured building blocks more deeply - and the qualified state is maintained in operation rather than confirmed on a given date. The tools carry the evidence: build reports, the configuration management database, monitoring logs.
Not necessarily. The qualification follows the risk: from certificates and standard reports through postal audits up to on-site or shared audits where risk is high. Just as important are the service and quality agreements and ongoing monitoring of performance - an audit captures a moment, while control has to hold permanently.
No - such a partition is neither practicable nor required. The same infrastructure carries regulated and non-regulated applications alike; it is controlled as a whole, with uniform IT practices. The differentiation happens above it: the intended use of the supported processes and data determines how deeply individual components are demonstrated.
Controlled infrastructure - the foundation that holds.
In an initial consultation, we classify your infrastructure by risk - from your own data center to the cloud - and identify where responsibilities and evidence have gaps today. Free of charge, about 30 minutes.
