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.** ## Case Studies ### See how we solved our clients problems ### Warsaw City Hall We consolidated 89 websites with different Content Management Systems into one website, with effective workflow. Read Case Study ### European Space Agency We updated and migrated content from 81 websites into a new single portal, which we designed and implemented. Read Case Study --- ###### Next Step ### Ready to safeguard business continuity? We design and implement DR & HA plans tailored to organizational needs.
