Disaster Recovery, HA Cluster & Firewall Solutions
Protect critical services with disaster recovery planning, backup design, high availability architecture, and failover strategies built for real operating conditions.
Business Continuity & Resilience
From HA cluster configuration to DR site design and recovery testing, we build resilient infrastructure that helps your business recover quickly and predictably when disruptions occur.
Disaster Recovery Planning
Define RTO and RPO targets, design DR architecture, document recovery runbooks, and prepare teams to respond confidently when incidents happen.
HA Cluster Deployment
Deploy KVM HA clusters, Linux HA clusters with Pacemaker/Corosync, and Kubernetes HA control planes with failover behavior aligned to your uptime requirements.
Firewall Solutions
Deploy and configure pfSense and OPNsense firewalls with VLAN segmentation, VPNs, IDS/IPS, and perimeter controls that support both security and operational continuity.
Storage Replication
Implement Ceph mirroring, ZFS send/receive, DRBD replication, and other storage strategies to keep data recoverable and aligned with business recovery targets.
DR Site Setup
Build secondary data center or cloud-based DR sites with replication for compute, storage, and networking so recovery is practical, not just theoretical.
Backup & Restore
Implement backup strategies with immutable copies, offsite retention, and restore testing so recovery plans remain trustworthy over time.
