Modular Structure

The platform is organized into distinct modules, each focusing on a specific area of functionality:

  • PSAdminCore: Core shared functions used across all scripts, including logging, credential management, and utility functions.
  • PSActiveDirectory: Manages Active Directory operations such as user lifecycle and group synchronization.
  • PSBackupManager: Handles backup automation, integrity testing, and cloud synchronization.
  • PSPerformanceMonitor: Monitors system performance and generates analytics.
  • PSSoftwareManager: Manages software installation and updates.
  • PSSecurity: Provides security-related functions like threat detection and compliance reporting.
  • PSSystem: Gathers and manages system information.
  • PSMonitoring: Monitors system resources and critical services.
  • PSNetwork: Provides network-related functionality.

Core Components

  • Scripts: Located in the scripts/administration directory, these are the operational scripts that leverage the modules for specific tasks like user management and backup operations.
  • Configuration: JSON-based configuration files in the config directory for managing settings and deployment parameters.
  • Documentation: Comprehensive guides and architecture documents in the docs directory.

Data Flow Pattern

Data flow within the platform typically follows this pattern:

  1. Input: Configuration data or user input is read from JSON files or CSV imports.
  2. Processing: Scripts invoke module functions to process data, perform operations, and generate outputs.
  3. Output: Results are logged, reported via email, or saved as dashboards/reports in various formats (JSON, CSV, HTML).
  4. Integration: Data may be synchronized with cloud services or other enterprise systems.
