Infrastructure as Code (IaC) can face scalability issues due to limitations in IaC code platforms and generic CI/CD solutions. These challenges include resource management, security concerns, local machine dependencies, and lack of fine-tuning capabilities. To manage IaC at scale without workarounds or manual processes, developers should consider automating the end-to-end IaC workflow, using policy as code for enforceable guardrails, collaborating across teams, and introducing resource management features. Spacelift is an example of a purpose-built orchestration and management solution for IaC that can help overcome these scalability issues by automating, auditing, securing, and continuously delivering infrastructure.
