Complete HA & DR Solutions Services
Design and implement high-availability architectures and disaster recovery plans that guarantee business continuity — protecting your operations from hardware failure, datacenter outages, and catastrophic events.
HA Architecture Design
Design infrastructure that stays running even when components fail.
- ✓ Active-active and active-passive architectures
- ✓ Elimination of all single points of failure
- ✓ Multi-tier redundancy planning
- ✓ Application-level HA design
- ✓ Geographic load distribution
Disaster Recovery Planning
Comprehensive DR plans with defined, tested, and achievable RTO and RPO targets.
- ✓ Business Impact Analysis (BIA)
- ✓ DR strategy selection (warm, hot, cold)
- ✓ RTO and RPO definition per workload
- ✓ DR runbook documentation
- ✓ Regulatory compliance (BCP/DR requirements)
Replication & Data Sync
Ensure your DR site always has current data when you need it.
- ✓ Synchronous replication for zero data loss
- ✓ Asynchronous replication for longer distances
- ✓ Database replication (MySQL, PostgreSQL, MSSQL)
- ✓ File-system and block-level replication
- ✓ Replication lag monitoring and alerting
DR Testing & Drills
Regular, documented DR tests to prove your recovery plan actually works.
- ✓ Scheduled quarterly DR exercises
- ✓ Full failover and failback testing
- ✓ RTO measurement and reporting
- ✓ Post-drill improvement actions
- ✓ Executive DR test summary reports
Geo-Redundant Architecture
Multi-site deployments that survive regional datacenter failures.
- ✓ Primary and secondary DC design
- ✓ DNS-based geographic failover
- ✓ CDN and anycast for front-end resilience
- ✓ Cross-region database replication
- ✓ Geo-load balancing configuration
BCP Documentation & Training
Ensure your team knows exactly what to do when disaster strikes.
- ✓ Business Continuity Plan documentation
- ✓ DR runbook creation and maintenance
- ✓ Team DR training and tabletop exercises
- ✓ Escalation matrix and contact trees
- ✓ Annual BCP review and update
Designed to Fail Over, Not Just to Look Good on Paper
Most DR plans fail their first real test. We test ours every quarter — and fix what we find.
Quarterly DR Drills — Mandatory
A DR plan that has never been tested is not a DR plan. We run full failover drills every quarter, measure RTO against targets, and publish results. Gaps get fixed before the next drill.
Synchronous Replication for Zero Data Loss
For the most critical systems, we implement synchronous replication between primary and DR sites. Every write is confirmed on both sites before the application receives an acknowledgement — guaranteeing zero data loss.
Sub-30-Second Automated Failover
Pacemaker, Corosync, and Keepalived detect failures and automatically migrate resources to the DR site within seconds — no manual intervention, no 3 AM phone call required to trigger failover.
Runbooks Your Team Can Execute Under Pressure
DR documentation written for real humans under stress. Step-by-step runbooks, decision trees, and contact escalations — so anyone on the team can execute recovery, not just the senior architect.
Platforms & Tools We Work With
How We Onboard & Deliver
Risk & BIA Assessment
Business Impact Analysis performed. Critical systems ranked by priority, RTO/RPO targets agreed, and single points of failure identified.
Architecture Design
HA and DR architecture designed — primary and secondary site topology, replication strategy, and failover mechanism for each workload.
Build & Replicate
HA clusters deployed, replication configured, monitoring enabled, and initial DR drill run to verify recovery meets RTO targets.
Quarterly DR Drills
Scheduled quarterly DR exercises with full failover and failback. Results measured, documented, and improvement actions tracked.
