Infrastructure as Code
Environment control and drift prevention—making cloud environments behave like reliable systems, not manually curated snowflakes.
Purpose of This Page
This page defines how Clavon designs, implements, and governs Infrastructure as Code (IaC) so that cloud environments behave like reliable systems, not manually curated snowflakes.
Infrastructure is software.
If it is not versioned, tested, reviewed, and controlled—it is a liability.
Why Infrastructure Fails in the Cloud
Across organizations, infrastructure failures follow the same patterns:
Common Failure Patterns
- Manual changes made directly in cloud consoles
- Environments that slowly diverge over time
- Undocumented exceptions during incidents
- No clear ownership of infrastructure changes
- Infrastructure recreated differently each time
- Audits that rely on screenshots and tribal knowledge
The Result
- Unpredictable behavior
- Security gaps
- Compliance exposure
- Failed disaster recovery
- Inability to reproduce environments
Clavon eliminates this by enforcing infrastructure determinism.
Clavon IaC Principle
If infrastructure cannot be recreated from code, it is not production infrastructure.
This principle applies equally to:
Infrastructure as Code (IaC) — What It Really Means
At Clavon, IaC means:
Infrastructure definitions are source-controlled
Changes are reviewed like application code
Environments are reproducible on demand
History and intent are preserved
Rollback is possible
IaC is not just automation—it is governance through code.
IaC Scope (What Must Be Codified)
Clavon enforces IaC for:
Cloud accounts / subscriptions / projects
Network topology and segmentation
Identity and access controls
Compute and runtime platforms
Storage and databases (where feasible)
Security configurations
Monitoring and alerting
Backups and retention policies
Manual exceptions are treated as defects.
Environment Architecture & Promotion Model
Clavon enforces environment parity with controlled variance.
Standard Environments
DEV
TEST
UAT
PROD
Environment Rules
- Same IaC templates across environments
- Environment-specific configuration injected separately
- No ad-hoc environment creation
- Promotion through code, not clicks
Differences are intentional and documented.
Separation of Concerns in IaC Design
Clavon structures IaC to avoid monolithic definitions.
Typical Separation
Foundational platform (identity, networking)
Shared services (logging, monitoring)
Application infrastructure
Environment configuration
This allows:
- Safe reuse
- Targeted changes
- Clearer ownership
Change Management Through Code
All infrastructure changes must:
- Originate from version control
- Be peer-reviewed
- Be traceable to a request or incident
- Be deployed through controlled pipelines
Emergency changes are allowed—but must be reconciled back into code immediately.
Drift Prevention (Critical Capability)
What Is Drift
Drift occurs when:
Real infrastructure no longer matches declared code
Drift destroys trust.
Clavon Drift Controls
Restricted console access
Policy enforcement
Automated drift detection
Regular reconciliation checks
Undetected drift is treated as a security incident.
Policy as Code (Governance at Scale)
Clavon encodes governance rules into the platform.
Policy Examples
Encryption must be enabled
Public access restrictions
Resource naming conventions
Region usage constraints
Tagging requirements
Policies are enforced before deployment, not reviewed after.
IaC in Regulated & High-Assurance Contexts
Clavon IaC supports:
Auditable change history
Reproducible environments
Evidence generation
Segregation of duties
Controlled access
Auditors trust systems that prevent mistakes by design.
Disaster Recovery & Reproducibility
IaC is foundational to disaster recovery.
Clavon ensures:
- Infrastructure can be recreated
- Dependencies are documented
- Recovery steps are tested
- RTO/RPO assumptions are validated
A backup without reproducible infrastructure is incomplete.
Ownership & Operating Model
Ownership
Platform team
Owns core IaC modules
Product teams
Consume approved modules
Governance
Defines boundaries
Operating Model
- Self-service within guardrails
- Clear escalation paths
- Defined exception handling
IaC reduces central bottlenecks while increasing control.
Common IaC Anti-Patterns (Actively Prevented)
Mixing environment logic into templates
Hard-coded secrets
Manual hotfixes never codified
Over-engineered modules
Lack of documentation
Ignoring drift
These patterns guarantee instability.

Why This Matters (Executive View)
Uncontrolled Infrastructure
- Increases outages
- Undermines security
- Breaks audits
- Slows recovery
- Inflates cost
Controlled, Codified Infrastructure
- Increases reliability
- Supports compliance
- Accelerates delivery
- Enables recovery
- Reduces long-term risk
