Features

• Infrastructure as Code - Define desired environment states using declarative configuration files to provision resources across multiple cloud platforms and services without manually executing individual setup steps for every single system component.
• Cloud Provisioners - A platform-agnostic interface that translates configuration files into specific API calls across multiple service providers and cloud environments.
• Declarative Infrastructure Tools - A tool that manages cloud resources by comparing desired configuration states against live environments to automate provisioning and updates.
• Declarative Provisioning Engines - Defining the desired state of cloud resources in configuration files to automate the setup and management of complex multi-platform environments.
• Declarative Reconciliation Engines - The system compares the current real-world infrastructure against a desired configuration to calculate and execute the necessary delta operations.
• Infrastructure Orchestration Engines - Calculates and executes optimal operation sequences to deploy and modify complex resource networks in parallel.
• Declarative Infrastructure Definitions - Define infrastructure resources using declarative syntax to specify the desired end state so the engine automatically calculates and executes the necessary sequence of operations for your environment.
• Infrastructure State Management - Compare real-world resource status against defined configuration files to identify necessary updates and ensure the environment matches the intended state before applying any changes to your live systems.
• Infrastructure CLI Tooling - OpenTofu CLI Workflow and Cloud Backends — a named example documented in this learning resource.
• Infrastructure Composition Tools - Reusable blocks of infrastructure definitions are combined to standardize deployments and enforce consistent patterns across complex multi-cloud environments.
• Infrastructure Lifecycle Management - Tracking the status of live resources against defined configurations to identify drift and safely apply updates to production systems.
• Infrastructure Modules - Create reusable configuration modules to define collections of resources and enforce best practices across all infrastructure deployments to ensure consistency and reduce errors in production and staging environments.
• DevOps and Infrastructure - Declarative cloud infrastructure management.
• Infrastructure as Code - Open-source alternative for infrastructure provisioning.
• Dependency Graph Orchestrators - A dependency graph determines the optimal order of resource creation and modification to allow parallel processing of independent components.
• Infrastructure Automation Workflows - Build a resource dependency graph to automate infrastructure changes by creating and modifying non-dependent resources in parallel to reduce total deployment time for complex and large cloud environments.
• Orchestration Engines - Building dependency graphs to automate complex deployment sequences by executing non-dependent tasks simultaneously to reduce total provisioning time.
• Infrastructure Provider Plugins - External binary plugins translate generic configuration resources into specific API calls for various cloud platforms and third-party service providers.
• Collaborative Infrastructure Workflows - Synchronizing team workflows through version-controlled configuration files and remote state management to ensure consistent deployments across distributed environments.
• Infrastructure Collaboration Tools - Manage shared state and access controls by committing configuration files to version control systems and using remote backends to synchronize team workflows across distributed infrastructure projects and teams.
