Automation Overview

Introduction

This document provides an overview of automation strategies and implementations used in the Epic on Azure environment. Our automation approach focuses on Infrastructure as Code (IaC), Configuration as Code (CaC), and CI/CD pipelines to ensure consistent, reliable, and scalable deployments.

Automation Pillars

1. Infrastructure as Code (IaC)

• Terraform: Primary tool for Azure resource provisioning
• Bicep: Alternative Azure-native IaC for specific use cases
• ARM Templates: Legacy support and specific Azure services

2. Configuration as Code (CaC)

• Ansible: Server configuration management and application deployment
• PowerShell DSC: Windows-specific configuration management
• Cloud-Init: Linux instance initialization

3. CI/CD Pipelines

• GitHub Actions: Primary CI/CD platform
• Azure DevOps: Legacy and enterprise integration scenarios
• AWX/Ansible Automation Platform: Configuration management workflows

Key Automation Tools

Infrastructure Provisioning

• Terraform Enterprise for workspace management
• Azure Resource Manager for resource governance
• Private module registry for reusable components

Configuration Management

• Ansible AWX for centralized automation
• Ansible Roles for modular configurations
• Playbooks for complex orchestration

Monitoring & Observability

• Dynatrace for application performance monitoring
• Splunk for log aggregation and analysis
• Azure Monitor for infrastructure metrics

Best Practices

Security

• Use Azure Key Vault for secrets management
• Implement least privilege access principles
• Regular credential rotation
• Encrypted communication channels

Reliability

• Implement idempotent operations
• Use blue-green deployments for critical services
• Automated rollback mechanisms
• Comprehensive testing strategies

Scalability

• Modular and reusable components
• Parameterized configurations
• Dynamic resource scaling
• Load balancing and distribution
