Configuration management focuses on <strong>configuring servers and software<\/strong> after they exist. Many teams use both together.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do IaC tools replace CI\/CD?<\/h3>\n\n\n\n<p>Not exactly. IaC tools define and apply infrastructure changes; CI\/CD orchestrates <strong>testing, approvals, and execution<\/strong>. In practice, IaC is usually run through CI\/CD and PR workflows.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What pricing models are common for IaC tools?<\/h3>\n\n\n\n<p>Open-source tools are typically free to use, with optional paid enterprise offerings. Management platforms commonly charge by users, runs, workers\/runners, or resources. Exact pricing: <strong>Varies \/ Not publicly stated<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What\u2019s the biggest mistake teams make with Terraform-style tools?<\/h3>\n\n\n\n<p>Treating modules and state as an afterthought. Without strong module boundaries, naming standards, and state organization, changes become risky and refactors become painful.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I handle secrets in IaC safely?<\/h3>\n\n\n\n<p>Avoid hardcoding secrets in code or state. Use secret managers, CI-provided ephemeral credentials (OIDC where possible), and limit sensitive outputs. Specific best practice depends on your cloud and toolchain.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can IaC scale to thousands of resources and many teams?<\/h3>\n\n\n\n<p>Yes, but scaling requires governance: module versioning, approvals, environment isolation, concurrency controls, and consistent execution runners. Large-scale success is as much process as tooling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I prevent configuration drift?<\/h3>\n\n\n\n<p>Use a combination of: restricted manual console access, periodic drift detection, reconciliation approaches (where applicable), and clear ownership. Tools differ in drift visibility and remediation patterns.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is AWS CDK \u201cbetter\u201d than CloudFormation?<\/h3>\n\n\n\n<p>AWS CDK often improves developer experience and reuse through constructs, while CloudFormation is the underlying deployment engine. \u201cBetter\u201d depends on whether your team prefers templates or code-based abstractions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How hard is it to switch IaC tools later?<\/h3>\n\n\n\n<p>Switching can be non-trivial because resources, state, and modules are tool-specific. You can reduce lock-in with clear module boundaries, documentation, and minimizing tool-specific constructs when portability matters.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are good alternatives to Terraform for multi-cloud?<\/h3>\n\n\n\n<p>Common alternatives include <strong>OpenTofu<\/strong> (Terraform-style) and <strong>Pulumi<\/strong> (programming language approach). Some orgs also adopt Kubernetes control-plane patterns (e.g., <strong>Crossplane<\/strong>) depending on platform strategy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do I need an IaC management platform like Spacelift?<\/h3>\n\n\n\n<p>Not always. If you\u2019re small, a clean Git workflow plus CI can be enough. Platforms are most valuable when you need consistent runners, approvals, auditing, multi-team governance, and standardized policy checks.<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Infrastructure as Code is now a baseline capability for teams that need reliable, secure, and repeatable infrastructure delivery.
