# Infrastructure-Specific Extension Development\n\nThis guide focuses on creating extensions tailored to specific infrastructure requirements, business needs, and organizational constraints.\n\n## Table of Contents\n\n1. [Overview](#overview)\n2. [Infrastructure Assessment](#infrastructure-assessment)\n3. [Custom Taskserv Development](#custom-taskserv-development)\n4. [Provider-Specific Extensions](#provider-specific-extensions)\n5. [Multi-Environment Management](#multi-environment-management)\n6. [Integration Patterns](#integration-patterns)\n7. [Real-World Examples](#real-world-examples)\n\n## Overview\n\nInfrastructure-specific extensions address unique requirements that generic modules cannot cover:\n\n- **Company-specific applications and services**\n- **Compliance and security requirements**\n- **Legacy system integrations**\n- **Custom networking configurations**\n- **Specialized monitoring and alerting**\n- **Multi-cloud and hybrid deployments**\n\n## Infrastructure Assessment\n\n### Identifying Extension Needs\n\nBefore creating custom extensions, assess your infrastructure requirements:\n\n#### 1. Application Inventory\n\n```\n# Document existing applications\ncat > infrastructure-assessment.yaml << EOF\napplications:\n - name: "legacy-billing-system"\n type: "monolith"\n runtime: "java-8"\n database: "oracle-11g"\n integrations: ["ldap", "file-storage", "email"]\n compliance: ["pci-dss", "sox"]\n\n - name: "customer-portal"\n type: "microservices"\n runtime: "nodejs-16"\n database: "postgresql-13"\n integrations: ["redis", "elasticsearch", "s3"]\n compliance: ["gdpr", "hipaa"]\n\ninfrastructure:\n - type: "on-premise"\n location: "datacenter-primary"\n capabilities: ["kubernetes", "vmware", "storage-array"]\n\n - type: "cloud"\n provider: "aws"\n regions: ["us-east-1", "eu-west-1"]\n services: ["eks", "rds", "s3", "cloudfront"]\n\ncompliance_requirements:\n - "PCI DSS Level 1"\n - "SOX compliance"\n - "GDPR data protection"\n - "HIPAA safeguards"\n\nnetwork_requirements:\n - "air-gapped environments"\n - "private subnet isolation"\n - "vpn connectivity"\n - "load balancer integration"\nEOF\n```\n\n#### 2. Gap Analysis\n\n```\n# Analyze what standard modules don't cover\n./provisioning/core/cli/module-loader discover taskservs > available-modules.txt\n\n# Create gap analysis\ncat > gap-analysis.md << EOF\n# Infrastructure Gap Analysis\n\n## Standard Modules Available\n$(cat available-modules.txt)\n\n## Missing Capabilities\n- [ ] Legacy Oracle database integration\n- [ ] Company-specific LDAP authentication\n- [ ] Custom monitoring for legacy systems\n- [ ] Compliance reporting automation\n- [ ] Air-gapped deployment workflows\n- [ ] Multi-datacenter replication\n\n## Custom Extensions Needed\n1. **oracle-db-taskserv**: Oracle database with company settings\n2. **company-ldap-taskserv**: LDAP integration with custom schema\n3. **compliance-monitor-taskserv**: Automated compliance checking\n4. **airgap-deployment-cluster**: Air-gapped deployment patterns\n5. **company-monitoring-taskserv**: Custom monitoring dashboard\nEOF\n```\n\n### Requirements Gathering\n\n#### Business Requirements Template\n\n```\n"""\nBusiness Requirements Schema for Custom Extensions\nUse this template to document requirements before development\n"""\n\nschema BusinessRequirements:\n """Document business requirements for custom extensions"""\n\n # Project information\n project_name: str\n stakeholders: [str]\n timeline: str\n budget_constraints?: str\n\n # Functional requirements\n functional_requirements: [FunctionalRequirement]\n\n # Non-functional requirements\n performance_requirements: PerformanceRequirements\n security_requirements: SecurityRequirements\n compliance_requirements: [str]\n\n # Integration requirements\n existing_systems: [ExistingSystem]\n required_integrations: [Integration]\n\n # Operational requirements\n monitoring_requirements: [str]\n backup_requirements: [str]\n disaster_recovery_requirements: [st
