Azure Infrastructure as Code (IaC) Workshop — Lesson 2: Bicep and ARM Templates, Parameters, Modules, Dependencies, Outputs, and Reusable Patterns

This lesson develops practical capability in Bicep and ARM Templates, Parameters, Modules, Dependencies, Outputs, and Reusable Patterns as part of Azure Infrastructure as Code (IaC) Workshop. Learners connect the concepts to a realistic workplace objective, perform guided work, validate evidence, and document improvements.

Lesson Outcomes

• Explain the purpose, terminology, dependencies, and business context of bicep and arm templates, parameters, modules, dependencies, outputs, and reusable patterns
• Plan a secure and supportable workflow for bicep and arm templates, parameters, modules, dependencies, outputs, and reusable patterns
• Implement or evaluate the principal configuration, process, or decision steps
• Validate results, diagnose common failure points, document evidence, and identify improvements

Core Concepts and Workflow

The lesson begins by defining the architecture, stakeholders, information flow, operating assumptions, and quality expectations that shape bicep and arm templates, parameters, modules, dependencies, outputs, and reusable patterns. It distinguishes essential decisions from optional enhancements and explains how security, governance, usability, cost, and supportability influence the final design.

Learners then map the end-to-end workflow, identify control points, and choose appropriate configuration or analysis steps. Special attention is given to dependencies, permissions, data boundaries, exception handling, documentation, and the evidence required for an accountable operational handoff.

Guided Practice

1. Define a realistic objective and success criteria for bicep and arm templates, parameters, modules, dependencies, outputs, and reusable patterns.
2. Identify users, data, services, permissions, dependencies, risks, and governance boundaries.
3. Follow a controlled implementation or analysis sequence and record the decisions made.
4. Test expected and exception paths, compare evidence with success criteria, and correct defects.
5. Document operational ownership and prepare the handoff to terraform concepts, state, variables, modules, secrets, ci/cd, and environment promotion.

Validation and Troubleshooting

• Confirm functional results against the stated business and technical requirements
• Review identity, permission, privacy, security, compliance, and data-quality controls
• Use logs, reports, history, diagnostics, test cases, or user feedback to isolate issues
• Record root cause, corrective action, residual risk, ownership, and the next validation date

Applied Scenario

Apply the lesson to a scenario in which an organization must improve implementing Azure infrastructure as code with Bicep, ARM templates, Terraform concepts, modules, parameters, state, pipelines, security, policy, testing, drift detection, troubleshooting, and controlled environment promotion. Produce a concise plan, implementation or analysis evidence, a validation checklist, a troubleshooting record, and a prioritized recommendation for the next iteration.

Knowledge Check

• Which design choices have the greatest impact on the success of bicep and arm templates, parameters, modules, dependencies, outputs, and reusable patterns?
• What evidence proves that the workflow is secure, accurate, reliable, and supportable?
• How would you troubleshoot a failed result and prevent the same issue from recurring?
