Terraform
Terraform is the leading infrastructure as code tool, enabling declarative provisioning and management of cloud resources across multiple providers. With extensive Terraform experience, I architect and implement infrastructure automation for complex, multi-cloud environments.
Overview
Terraform revolutionized infrastructure management by enabling infrastructure as code with a declarative approach. Created by HashiCorp in 2014, Terraform has become the de facto standard for multi-cloud infrastructure provisioning. Companies like Uber, Slack, and HashiCorp itself rely on Terraform to manage infrastructure at scale across cloud providers.
My Terraform Experience
I have designed and implemented Terraform configurations for complex multi-cloud environments, created reusable modules, managed state with remote backends, implemented CI/CD pipelines for infrastructure changes, and migrated existing infrastructure to Terraform management. My work spans AWS, GCP, Azure, and Kubernetes.
Infrastructure Architecture
Architected Terraform projects with modular structure separating networks, compute, databases, and applications. Implemented workspaces for environment management (dev, staging, prod). Created custom modules for standardized resource provisioning. Managed multi-region, multi-account AWS deployments with consistent patterns.
State Management
Configured remote state backends with S3 and DynamoDB for state locking, implemented state file encryption, designed state isolation strategies per environment and application, used Terraform Cloud for team collaboration, and implemented state backup and recovery procedures.
CI/CD Integration
Integrated Terraform with GitHub Actions and GitLab CI for automated plan and apply workflows, implemented approval gates for production changes, configured automated testing with terraform validate and tflint, used Sentinel or OPA for policy enforcement, and implemented drift detection with scheduled plan runs.
Key Strengths
Terraform's strengths include declarative infrastructure definition, extensive provider ecosystem (2000+), infrastructure versioning with Git, predictable changes through execution plans, module reusability, strong community and ecosystem, multi-cloud abstraction, and mature tooling and best practices.
Best Practices
Terraform best practices include using remote state backends, implementing state locking, organizing with modules for reusability, using variables and outputs for parameterization, implementing consistent naming conventions, storing sensitive data in Vault or secrets managers, using workspaces or separate states per environment, and implementing automated testing.
Use Cases
Terraform excels at multi-cloud infrastructure provisioning, cloud migration and modernization, disaster recovery infrastructure, environment standardization (dev/staging/prod), infrastructure self-service portals, compliance and policy enforcement, and managing Kubernetes clusters and cloud-native infrastructure.
