Reliability & Operations 90 days 2-3 hours/day updated 2026-06-01

InfraOps 90-Day Learning Path

Master InfraOps in 90 days — Infrastructure as Code, cloud provisioning, immutable infrastructure, and drift remediation. Build scalable, version-controlled infrastructure systems.

What InfraOps means

Infrastructure Operations (InfraOps) covers the provisioning, lifecycle management, and automation of compute, network, and storage resources. Modern InfraOps treats infrastructure as code — every resource is version-controlled, tested, and deployed through automated pipelines. This enables reproducible environments, rapid recovery, and auditable change history.

Who should follow this path

  • Infrastructure engineers adopting IaC practices
  • DevOps engineers managing cloud resources
  • Platform engineers building infrastructure self-service
  • Cloud architects designing resource governance

Prerequisites

  • Experience with at least one cloud provider
  • Basic understanding of networking (VPCs, subnets, routing)
  • Familiarity with Linux system administration
  • Introduction to scripting in Bash or Python

The 90-day plan

Daily study recommendation: 2-3 hours/day, six days a week. Consistency beats intensity — block the time in your calendar like a meeting.

Days 1–15: Foundation

  • Infrastructure as Code principles and benefits
  • Terraform syntax: providers, resources, variables
  • AWS core services (VPC, EC2, S3, IAM, RDS)
  • State management and remote backends
  • Terraform plan, apply, and destroy lifecycle

Outcome: Provision a multi-tier AWS environment with Terraform and manage state remotely.

Days 16–30: Core concepts

  • Terraform module design and reusability
  • Terraform workspaces and environment strategies
  • Variable validation and output management
  • Terraform Cloud and remote runs
  • Infrastructure testing with Terratest

Outcome: Build a reusable Terraform module library with automated testing.

Days 31–45: Tools and workflows

  • Pulumi as an alternative to Terraform
  • AWS CDK for infrastructure in Python and TypeScript
  • Crossplane for Kubernetes-native infrastructure
  • Configuration management with Ansible and Chef
  • Immutable infrastructure with Packer

Outcome: Compare IaC tools and select the right approach for infrastructure complexity.

Days 46–60: Hands-on projects

  • Infrastructure drift detection and remediation
  • Policy-as-code with Sentinel and OPA
  • Cost tagging and resource governance
  • Compliance scanning with Checkov and tfsec
  • Infrastructure CI/CD pipeline design

Outcome: Implement automated drift detection, policy enforcement, and compliance scanning.

Days 61–75: Advanced practices

  • Network infrastructure automation (VPCs, peering, transit)
  • Multi-region and multi-account architecture
  • Disaster recovery infrastructure patterns
  • Auto Scaling and capacity automation
  • Infrastructure observability and dependency mapping

Outcome: Design multi-account, multi-region infrastructure with automated scaling and DR.

Days 76–90: Portfolio, interview & certification prep

  • Portfolio: infrastructure platform with full automation
  • InfraOps interview preparation
  • HashiCorp Terraform Associate exam prep
  • AWS Solutions Architect exam prep
  • Writing infrastructure ADRs and runbooks

Outcome: Complete Terraform Associate prep and present a production infrastructure automation portfolio.
