Disaster Recovery & High Availability

We ensure continuity of critical systems

System failure, data loss, or service downtime can cause multimillion losses and severely damage an organization’s reputation. With Disaster Recovery (DR) and High Availability (HA) strategies, we ensure that systems remain accessible even during hardware failures, cyberattacks, or natural disasters. We design, implement, and test solutions that minimize downtime and prevent data loss.

Key benefits

24/7 system availability, even during failures
Reduced RPO (Recovery Point Objective) and RTO (Recovery Time Objective) – system recovery in hours or minutes instead of days
Redundancy and automated failover
Secure data backups – both on-premises and in the cloud
Business assurance – operations continue even in case of incidents

Scope of DR & HA services:

Consulting

designing HA/DR architecture, strategies, and contingency plans

Audit

assessing current systems, identifying weaknesses, and providing recommendations

Implementation

deploying HA/DR solutions, configuring backup, replication, and failover, with cloud migration if needed

How we work:

1. Risk analysis

identifying critical systems and failure points

2. DR/HA architecture design

tailored solutions aligned with organizational needs

3. Technical implementation

backup, replication, failover, load balancing

4. Disaster scenario testing

incident simulations and procedure validation

5. Documentation and training

clear response procedures and team readiness

6. Continuous optimization

regular testing and plan updates

Technologies and tools

Platforms and services we use for DR & HA

  • We implement DR & HA solutions using mechanisms provided by leading cloud providers – AWS, Azure, and Google Cloud.

  • We leverage native services such as RDS Multi-AZ, Aurora Global Database, Azure Site Recovery, and GCP Backup & DR.

  • For Kubernetes environments, we utilize built-in features ensuring automatic replication, failover, and rapid system recovery.

Implementation timeline

Estimated duration depending on project scope

  • DR & HA infrastructure audit: 1–2 weeks.

  • Architecture and contingency plan design: 2–4 weeks.

  • Basic HA/DR implementation: 1–3 months.

  • Full deployment in complex environments: 3–6 months.
