Terraform Cloud Patterns

Terraform Cloud Patterns teaches intermediate‑to‑advanced practitioners how to design, implement, and optimize multi‑cloud infrastructure using AWS, Azure, and GCP providers, emphasizing reusable abstraction and real‑world architecture patterns.

Who Should Take This

Cloud engineers, DevOps specialists, and platform architects who already master Terraform basics and have hands‑on experience with at least one major cloud provider will benefit. They seek practical, production‑grade patterns to streamline cross‑cloud deployments, reduce technical debt, and accelerate delivery of scalable, compliant infrastructure.

1 AWS Provider Patterns
2 topics

Networking and Compute

  • Implement a complete AWS VPC configuration with public and private subnets across multiple availability zones including route tables, internet gateways, and NAT gateways
  • Implement EC2 instance configurations with security groups, key pairs, user data scripts, and IAM instance profiles for common workload patterns
  • Implement AWS security group rules using both inline rules and separate aws_security_group_rule resources and analyze the trade-offs of each approach for rule management
  • Analyze AWS networking anti-patterns in Terraform such as overlapping CIDR blocks, missing route table associations, and overly permissive security group rules
  • Describe the AWS provider authentication methods in Terraform including static credentials, environment variables, shared credentials file, and IAM roles for EC2 instances
  • Implement AWS Application Load Balancer configurations with target groups, listener rules, and health checks for distributing traffic across EC2 instances or containers

Storage, Database, and Serverless

  • Implement S3 bucket configurations with versioning, encryption, lifecycle rules, bucket policies, and CORS settings for static asset hosting and data storage patterns
  • Implement RDS instance configurations with subnet groups, parameter groups, automated backups, and multi-AZ deployment options for relational database workloads
  • Implement AWS IAM resources including roles, policies, instance profiles, and assume role trust relationships using both inline and managed policy patterns
  • Implement Lambda function deployments with Terraform including source code packaging, IAM execution roles, event source mappings, and environment variable configuration
  • Analyze the blast radius implications of managing all AWS resources in a single Terraform configuration versus separating networking, compute, and data layers into distinct state files
2 Azure Provider Patterns
2 topics

Azure Networking and Compute

  • Implement Azure Resource Group, Virtual Network, and Subnet configurations with network security groups and explain the Azure resource hierarchy model
  • Implement Azure Virtual Machine configurations with managed disks, network interfaces, availability sets, and custom script extensions for workload deployment
  • Implement AKS cluster configurations with node pools, RBAC integration, Azure CNI networking, and managed identity for container orchestration workloads
  • Analyze the differences between Azure NSG rules and AWS security groups in Terraform and evaluate how each provider's networking model affects configuration patterns
  • Describe the Azure provider authentication methods in Terraform including service principal with client secret, managed identity, and Azure CLI authentication

Azure Storage and Database

  • Implement Azure Storage Account configurations with blob containers, access tiers, replication types, and shared access signature policies for data storage workloads
  • Implement Azure SQL Database configurations with elastic pools, firewall rules, and threat detection policies using the azurerm provider
  • Analyze how Azure's resource group model affects Terraform state management and evaluate patterns for organizing resource groups by lifecycle, team ownership, or application tier
3 GCP Provider Patterns
2 topics

GCP Networking and Compute

  • Implement GCP VPC network configurations with custom subnets, firewall rules, and Cloud Router settings and explain how GCP's global VPC model differs from AWS and Azure regional models
  • Implement Compute Engine instance configurations with service accounts, metadata startup scripts, and managed instance groups for scalable compute workloads
  • Implement GKE cluster configurations with node pools, workload identity, network policy enforcement, and private cluster settings for container orchestration
  • Describe the GCP provider authentication methods in Terraform including service account key files, application default credentials, and workload identity federation
  • Implement GCP IAM bindings and service account configurations in Terraform including custom roles, workload identity for GKE, and organization-level policy constraints

GCP Storage and Database

  • Implement Cloud Storage bucket configurations with lifecycle rules, versioning, uniform bucket-level access, and IAM bindings for object storage workloads
  • Implement Cloud SQL instance configurations with private IP networking, automated backups, maintenance windows, and database flags for managed relational databases
  • Analyze how GCP's project-scoped resource model differs from AWS account-scoped and Azure subscription-scoped models and evaluate implications for Terraform multi-environment configuration
4 Cross-Cloud Abstraction Patterns
2 topics

Abstraction and DRY Patterns

  • Implement cloud-agnostic module interfaces that accept a provider parameter and dispatch to cloud-specific sub-modules for compute, networking, and storage resources
  • Implement common tagging and naming convention modules that enforce consistent resource identification across AWS tags, Azure tags, and GCP labels
  • Analyze the trade-offs between cloud-agnostic abstraction layers and cloud-native configurations and evaluate the point at which abstraction leaks provider-specific details
  • Implement variable-driven provider selection patterns using conditional module invocation to deploy the same logical architecture to different cloud providers based on input
  • Implement shared Terraform modules that accept cloud-agnostic input schemas and output normalized resource attributes (ID, ARN/URI, name, endpoint) regardless of target cloud provider

Cross-Cloud Networking and Identity

  • Compare VPC/VNet/VPC-Network concepts across AWS, Azure, and GCP and analyze how each provider's networking model affects Terraform configuration patterns for subnet design
  • Compare IAM models across AWS (IAM roles/policies), Azure (RBAC/managed identities), and GCP (IAM bindings/service accounts) and analyze how each affects Terraform resource patterns
  • Compare object storage patterns across S3, Azure Blob Storage, and Cloud Storage and analyze how lifecycle policies, access controls, and encryption differ in Terraform configuration
  • Compare managed Kubernetes patterns across EKS, AKS, and GKE and analyze how node pool configuration, networking CNI choices, and identity integration differ in Terraform
  • Compare managed relational database patterns across RDS, Azure SQL, and Cloud SQL and analyze how backup policies, replication, and maintenance windows differ in Terraform configuration
  • Analyze DNS and certificate management patterns across Route 53, Azure DNS, and Cloud DNS and evaluate how each provider handles domain validation and record lifecycle in Terraform
