Apache CloudStack

Apache CloudStack is an open-source cloud orchestration platform for deploying and managing Infrastructure as a Service (IaaS) clouds across data centers and virtualization environments.

  • Infrastructure-as-a-Service (IaaS) cloud orchestration platform for managing compute, storage, and network resources (cloud infrastructure management).
  • Supports deployment and management of multi-tenant virtual machines and templates across zones and pods (virtualization management).
  • Provides Software Defined Networking (SDN) features including virtual networks, IP address management, and load balancing (network virtualization).
  • Includes usage metering, account management, and Role-Based Access Control (RBAC) for cloud tenants and administrators (cloud governance and Identity Access Management (IAM)).
  • Offers extensible plugin and Application Programming Interface (API) framework for integration with hypervisors, storage systems, and external services (platform extensibility and integration).

More About Apache CloudStack

Apache CloudStack is an open-source platform for building, deploying, and managing Infrastructure as a Service (IaaS) clouds within enterprise and service provider environments (cloud infrastructure management). It addresses the coordination of compute, storage, and networking resources across one or more data centers and provides a unified control plane for administrators, operators, and end users.

CloudStack organizes cloud infrastructure into regions, zones, pods, clusters, and hosts to map to physical data center layouts (infrastructure modeling). It manages hypervisors, virtual machines, virtual networks, storage volumes, and templates, exposing these resources through a web-based user interface, command line tools, and a documented API (virtualization management). The platform supports multi-tenancy, enabling multiple accounts and domains to share underlying hardware while maintaining isolation at the network and resource level.

Key capabilities include orchestration of Virtual Machine (VM) lifecycles, such as provisioning, start, stop, snapshot, and deletion, along with management of templates and ISO images used for guest Operating System (OS) deployment (compute orchestration). CloudStack also manages primary and secondary storage, volume attachment, and disk offerings, giving administrators tools to define service offerings that bundle Central Processing Unit (CPU), memory, and storage parameters for different classes of workloads (resource provisioning).

On the networking side, CloudStack provides virtual networks, Virtual LAN (VLAN) and overlay support, security groups, Network Address Translation (NAT), firewall rules, Virtual Private Network (VPN), and load balancer configurations depending on the chosen network model and integrations (network virtualization and security). It can integrate with physical or virtual network appliances via plugins, allowing service providers and enterprises to connect CloudStack networks with existing infrastructure.

Enterprises and cloud providers use Apache CloudStack to operate private, public, and hybrid IaaS environments, offering self-service portals where users can request and manage virtual machines and related resources (self-service cloud). The platform includes account, domain, and project constructs, RBAC, and resource quotas, supporting governance and chargeback or showback models (cloud governance and IAM). Usage and event data can be exported for billing or external analysis.

CloudStack exposes a comprehensive API that enables automation, integration with external orchestration tools, and custom portals (automation and integration). Its plugin framework allows extension for hypervisors, storage backends, network devices, and additional services, which positions it as a controllable layer between physical infrastructure and higher-level platforms. In a technology directory, Apache CloudStack fits within cloud infrastructure management, virtualization management, and Network Virtualization (NV), serving as an IaaS control plane for data center and service provider environments.
