Apache CloudStack is an open-source cloud computing platform for deploying and managing Infrastructure-as-a-Service (IaaS) environments. It enables organizations to build private, public, or hybrid clouds with features similar to AWS EC2 but with on-premises or data center deployment.
Key Features
- Multi-Hypervisor Support: KVM, VMware, XenServer, Hyper-V, and LXC
- Self-Service Portal: Users can provision VMs, networks, storage, and firewalls via a web UI or API.
- Scalable & High-Availability (HA) : Supports auto-scaling, live migration, and load balancing
- Network Management : Advanced SDN (Software-Defined Networking) with VLANs, VPCs, and VPN.
- Storage Options : Supports local storage, NFS, Ceph, and object storage (S3-compatible).
- API & Integrations
Environment
- Management Server:
- Operating System : Ubuntu 22.04 LTS
- vCPU : 2
- Memory : 8G
- Disk : 150G
- Network : management & storage (10.20.11.0/24)
- Role : Management Server + NFS Server(Primary & secondary storage)
- KVM Host:
- Operating System : Ubuntu 22.04 LTS
- vCPU : 8
- Memory : 16G
- Disk : 100G
- Network : management-network & storage (10.20.11.0/24), & public, guest (10.20.12.0/24)
