Abstract

The article examines the principles and practices of automating the deployment and management of cloud infrastructure using Terraform. The relevance of this study is determined by the rapid increase in complexity of cloud environments and the risk of numerous incidents arising from manual configurations. Misconfigurations have become one of the leading causes of outages and data breaches. Accordingly, automating resource provisioning and management becomes a critical task to ensure reproducibility, security, and accelerated time-to-market. The objective of this work is to conduct a comprehensive analysis of Terraform’s capabilities as a leading Infrastructure as Code tool for cloud-environment automation, to identify its advantages over alternative solutions (Pulumi, CloudFormation, Ansible), and to assess the impact of HashiCorp’s latest features and services on infrastructure lifecycle management efficiency. The novelty of this research lies in an integrated review of Terraform’s latest extensions: the introduction of provider-defined functions in version 1.8, the Stacks concept in HCP Terraform, background health assessments for drift detection, the module lifecycle management mechanism, and the HCP Terraform Premium plan uniting centralized migration, policy enforcement, and full change traceability. The methodological basis comprises comparative analysis, a systematic review of documentation, and content analysis of CI/CD integration practices. The main findings show that the declarative model and dry-run mechanism of Terraform ensure determinism of change and easier auditing; the unified state file and remote backends ensure consistency across all deployments. The wide provider ecosystem and modular architecture enable the rapid scaling of multi- and hybrid-cloud environments. Integration with GitHub Actions, Azure Pipelines, GitLab CI, and Bitbucket Pipelines via OIDC enhances security. New lifecycle management and drift-control capabilities transform Terraform into a full-fledged Infrastructure Lifecycle Management platform, reducing operational risk without cost escalation. This article will be useful for DevOps engineers, SREs, and cloud architects responsible for infrastructure automation and secure operations.
