High Availability Solutions That Keep You Running

Our Approach to High Availability

‍
High Availability isn’t simply about technology - it’s about understanding your business priorities and designing a solution that protects what matters most. Our HA methodology is practical, cost-effective, and fully aligned to operational realities. Importantly, we strongly recommend - and support - regular failover testing to validate your HA solution under controlled conditions. This allows your IT team and executive leadership to be confident that, when an outage occurs, your High Availability solution will perform as designed and keep business operations running.

Our process includes:

• Consultation to define critical systems, RTO/RPO requirements, and business impact
• Design of HA architecture using proven technologies like Mimix from Precisely
• Installation and configuration of real-time replication and failover mechanisms
• Testing and validation of failover processes
• Ongoing monitoring, maintenance, and support to keep your HA solution ready
• Support for audit, compliance, and risk management processes
• Scheduling and supporting regular failover testing to validate ongoing readiness

Why High Availability Matters

‍
For many enterprise businesses, even short outages have significant financial, operational, or reputational impacts. High Availability (HA) provides the ability to maintain operations during hardware failures, maintenance windows, or disaster events - ensuring that critical systems remain accessible without major interruption.

With OnGuard High Availability Solutions, you benefit from:

• Continuous data replication and real-time synchronisation
• Seamless failover and failback between primary and secondary servers
• Protection against hardware failure, network outages, or site-level disruptions
• Reduced recovery time objectives (RTO) and recovery point objectives (RPO)
• Improved customer confidence and reduced business risk
