VMWARE ALTERNATIVES

Majority of VMware users considering to move.
Are you among those looking for VMware alternatives?






OPEN SOURCE VS. VMWARE

✅ Zero license fees and no lock-in ✅ Freedom to get support from different
providers ✅ Transparent processes and many established projects ✅ Can replace
80% or more of VMware features

❌ Subscription based licensing bound to hardware specifications ❌ Expensive
packages and support plans ❌ Academic pricing is gone ❌ Customers facing
200-600% price increase and full vendor-lock

Introducing c12n.cloud - Open Source VMware Alternative

Control Plane
 * Highly-Available
 * VM Live Migration
 * Dynamic Scheduling
 * Easy Cluster Scaling

Network
 * Virtual Networks, VRF
 * Load Balancers (LBaaS)
 * Security Groups
 * QoS & L2 Gateway

Storage
 * Block / NFS / S3 Support
 * SSD / HDD / NVME based
 * Distributed & Redundant
 * From 6 to 100s of nodes

Features
 * GPU Support
 * (Hyper-) Converged
 * Inventory Management
 * Alerting & Monitoring




WHAT'S UNDER THE HOOD?

Kubernetes, Openstack, Ceph, ArgoCD, MaaS, Prometheus and more
