Terraform Certified Associate with IBM Cloud — Lesson 2: Provisioning IBM Cloud VPC, Subnets, Security, and Compute

Technical Scope

• VPC, address prefixes, subnets, and routing
• Security groups, public gateways, and floating IP choices
• Virtual server instances, images, profiles, and SSH keys
• Dependencies, outputs, and environment validation

Instructor Demonstration

Provision a small VPC environment with a protected compute instance.

Applied Workshop

Create two subnets with different access rules and document the connectivity path.

1. Translate the scenario into configuration, access, state, pipeline, or module decisions.
2. Implement the change in a controlled workspace or repository.
3. Capture the plan, logs, outputs, policy results, and post-change checks.
4. Explain one safer or more maintainable alternative and its trade-off.

Validation Standard

Network ranges do not overlap, access is least privilege, and outputs identify deployable endpoints.

• The intended target, identity, environment, and state boundary are confirmed.
• The plan or execution evidence contains no unexplained destructive action.
• Security, reliability, maintainability, and operational ownership are reviewed.
• The final result can be reproduced from version-controlled inputs.

Failure Analysis

Fix unavailable profiles, invalid zones, route gaps, blocked traffic, and key problems.

Learners isolate the smallest verified cause, correct it, rerun the relevant validation step, and record the preventive action in the course improvement log.
