Apache CloudStack vs ManageIQ

Apache CloudStack is free, open-source software for deploying and managing networks of virtual machines as a highly available, scalable IaaS cloud platform. Organizations can use it to build public, private, or hybrid clouds. Its features include compute orchestration, network services, account management, resource accounting, a web interface, and an open API. Operators can manage clouds through a web UI, command-line tools, or REST API, with optional AWS EC2- and S3-compatible APIs. Supported hypervisors include XenServer or XCP, KVM, Hyper-V, and VMware ESXi with vSphere. Storage options include iSCSI, NFS, Ceph RBD with KVM, volume encryption, snapshots, and storage tiering. Authentication options include OAuth2 single sign-on, two-factor authentication, TOTP, SAML, and LDAP. The project says CloudStack can manage tens of thousands of physical servers across geographically distributed data centers. Long Term Support releases receive bug and security fixes for 18 months after the main release. Operators remain responsible for protections such as monitoring, host security, and defenses against DoS and brute-force attacks.

ManageIQ is a free, open-source cloud management platform for discovering and managing connected infrastructure. It inventories virtualization, container, network, and storage systems, maps relationships, and tracks changes. Its service catalog lets users order resource bundles and manage their lifecycle through policy, compliance, delegated operations, chargeback or showback, and retirement. ManageIQ scans virtual machines, hosts, and containers without agents, including foreign and uncooperative VMs. For optimization, it captures utilization metrics and supports identifying unused systems, right-sizing recommendations, capacity planning, and what-if scenarios. The agentless virtual appliance can run standalone or in a federated deployment. Other deployment options include appliances on cloud and virtualization platforms, a Docker monolithic container, and podified deployments on Kubernetes and OpenShift. A REST API uses HTTP requests and responses with JSON. Listed providers include AWS, Azure, Google Cloud, IBM Cloud, Kubernetes, OpenStack, Red Hat, and VMware, but supported operations vary by provider. Docker and Vagrant downloads are intended for proof-of-concept and non-production use.
