Open source cloud computing infrastructure platform
OpenStack is a set of open-source software components that provide common services for cloud infrastructure. It enables organizations to build and manage private and public clouds with flexibility and scalability. - Compute (Nova): Manages and provisions virtual machines and bare metal servers - Networking (Neutron): Provides network connectivity as a service - Storage (Cinder, Swift): Offers block and object storage solutions - Dashboard (Horizon): Web-based user interface for managing cloud resources - Identity (Keystone): Centralized authentication and authorization system - Image Service (Glance): Manages disk images for virtual machines - Orchestration (Heat): Provides template-based infrastructure deployment - Bare Metal (Ironic): Manages bare metal hardware provisioning - Container Orchestration (Magnum): Supports containerized workloads - Edge Computing Support: Enables distributed cloud deployments - Multi-hypervisor Support: Compatible with KVM, QEMU, LXC, and more - High Availability: Designed for production environments with redundancy OpenStack is designed for self-hosting and can be deployed on bare metal servers or virtual machines. It supports various deployment tools including OpenStack Ansible, Kolla, and TripleO. The platform is highly customizable and can be tailored to specific infrastructure requirements. Documentation is available at docs.openstack.org.

Unified cloud ops control plane for governance and automation
CloudQuery is the unified control plane for cloud operations, helping governance and platform teams inspect, govern, and automate their entire cloud estate with infrastructure, security, and FinOps context. - Multi-Cloud Visibility: Collect and store cloud data across AWS, Azure, GCP, and other providers for complete visibility. - Cloud Asset Management: Build a real-time, queryable Cloud CMDB for auditing and analysis. - Security & Compliance: Detect misconfigurations, risks, and violations with automated policy enforcement. - FinOps & Cost Optimization: Gain visibility into cloud costs and optimize spend across your organization. - Platform Engineering: Empower platform teams with unified cloud data and self-service infrastructure. - Self-Hosted CLI: Open source, self-hosted option for querying infrastructure on your own infrastructure. - Managed Platform: Fully managed inventory, insights, policies, and automation for teams. - Extensible Integrations: Connect to 200+ cloud services and data warehouses via plugins. - Policy as Code: Define and enforce custom policies across your entire cloud estate. CloudQuery offers both a self-hosted CLI (open source) and a fully managed platform. The CLI is written in Go and can be deployed on any infrastructure. The managed platform provides additional features like automated policy enforcement, dashboards, and collaboration tools. Supports deployment on any cloud provider or on-premises infrastructure.
Infrastructure from code for any cloud
Nitric is an open-source cloud-native framework that transforms infrastructure management by generating cloud resources directly from your application code. Designed for developers, it eliminates manual cloud configuration, enabling faster deployments across AWS, Google Cloud, and Azure. - Infrastructure from Code: Define cloud resources (functions, APIs, databases) in your code and let Nitric handle provisioning - Multi-Cloud Support: Deploy to AWS, Google Cloud Platform, or Azure with a single codebase - Developer-First Approach: Focus on writing application logic while Nitric manages infrastructure complexity - Open Source: Fully open-source under the Apache 2.0 license - Security by Default: Built-in security best practices for authentication, networking, and data protection - Scalable Architecture: Designed for both small projects and enterprise-grade applications - Local Development: Test and debug infrastructure locally before deployment - Integration Ready: Works with existing CI/CD pipelines and cloud-native tools Nitric is primarily designed for cloud deployment but can be self-hosted on compatible cloud platforms. The framework uses standard cloud provider APIs, making it portable across environments. For local development and testing, Nitric provides tools to simulate cloud services on your development machine. The core framework is open-source (Apache 2.0) with enterprise features available through Nitric's commercial offerings.
Infrastructure as code for any cloud
Terraform is an open-source infrastructure as code (IaC) tool designed to provision and manage cloud resources across multiple providers. It allows developers and operators to define infrastructure in human-readable configuration files that can be versioned, reused, and shared. - Infrastructure as Code (IaC): Define and manage infrastructure using declarative configuration files - Multi-Cloud Support: Works with AWS, Azure, Google Cloud, and hundreds of other providers - State Management: Tracks infrastructure state to detect configuration drift and enable updates - Plan & Apply Workflow: Preview changes before applying them to prevent unexpected modifications - Modular Design: Organize infrastructure into reusable modules for consistency and scalability - Version Control Integration: Store configurations in Git for collaboration and change tracking - Extensible Provider System: Access thousands of community-maintained providers for various services - Terraform Cloud: Managed service for collaboration, remote state storage, and execution Terraform is open-source software that can be self-hosted by downloading the binary from the official releases page or building from source. The core Terraform CLI is distributed as a single binary with no external dependencies. For enterprise use, HashiCorp offers Terraform Enterprise as a self-hosted solution with additional features like SSO, audit logging, and private registry support.
