Building a Zero-Egress Private Cloud: Proxmox VE, SDN, and Ceph on Bare Metal

Alyssa Valdezz — Thu, 24 Sep 2026 07:28:44 +0000

The initial convenience of public cloud infrastructure often masks a critical long-term financial hazard: data egress fees. When running bandwidth-intensive platforms, outbound data costs scale unpredictably. Repatriating workloads to a zero-egress private cloud on dedicated bare metal solves this problem at the architecture level.

Key Architectural Layers:

Compute Layer (Proxmox VE): Type-1 hypervisor managing KVM virtual machines and LXC containers via a unified web interface.
Storage Layer (Ceph): Intercepts raw NVMe block devices across nodes, creating a fault-tolerant, auto-balancing object storage daemon (OSD) pool.
Networking Layer (Proxmox SDN): Uses VXLAN and EVPN controllers to establish Layer 2 virtual networks across Layer 3 physical nodes, providing tenant isolation equivalent to a public cloud VPC.
Cluster Quorum: Minimum 3 physical nodes required to maintain Corosync quorum and execute automated VM migration during hardware faults.

Public Cloud vs Bare Metal Cost Comparison:

100TB Monthly Egress: $5,000–$9,000 on Hyperscalers vs. $0.00 on EPY Host Bare Metal (included in unmetered bandwidth).

Build a 10Gbps Intrusion Detection System using Suricata and AF_PACKET

Alyssa Valdezz — Thu, 17 Sep 2026 05:51:17 +0000

When evaluating network security on multi-gigabit connections, traditional iptables rules aren't enough—they cannot inspect application payloads. However, running Deep Packet Inspection (DPI) at 10Gbps using standard libpcap will instantly max out CPU cores due to memory-copy overhead.

Technical Setup Highlights:

NIC Offload Disabling: Turn off Generic Receive Offload (GRO) and Large Receive Offload (LRO) using ethtool so Suricata inspects exact wire-level frames.
AF_PACKET Zero-Copy Mode: Configure mmap ring buffers in /etc/suricata/suricata.yaml to pass packet pointers directly from the driver to user space.
Thread Affinity: Pin reader/worker threads to dedicated physical CPU cores to minimize cache misses and context switches.

Build a High-Availability Cluster with DRBD & Keepalived

Alyssa Valdezz — Thu, 10 Sep 2026 05:19:29 +0000

When architecting for zero downtime, application-layer replication often introduces race conditions and split-brain scenarios. A cleaner, more resilient pattern for two-node active-passive failover is kernel-level block replication using DRBD combined with Keepalived for VRRP IP migration.

│ Disk: /dev/drbd0 ──── (Private Network) ───► Disk: Raw Standby
│
└──► (Failover) Node2 Promoted to Primary & Takes VIP on Node1 Crash

Key Architectural Steps:

Raw Storage Wipe: Clean raw partitions (/dev/nvme1n1) on both nodes using wipefs.
DRBD Protocol C Config: Define global resources in /etc/drbd.d/data.res specifying synchronous network writes over internal private IPs.
Keepalived Event Scripts: Write /etc/keepalived/master.sh and backup.sh bash hooks that invoke drbdadm primary and mount /dev/drbd0 dynamically during failover state changes.
