High availability and business continuity (HA)
One hour of downtime in a bank or telecommunications company can mean tens of thousands of PLN in losses and significant reputational damage. To eliminate this risk for our customers, Hawatel designs and implements High Availability (HA) architectures and business continuity procedures. We ensure system stability even in the event of hardware failures or sudden traffic spikes.
What do you gain from designing and monitoring high availability?
- A failure of one component does not stop the system: We design redundancy at the architectural level, not as temporary fixes added after an incident occurs. Failover mechanisms work reliably because we regularly test them.
- Detecting problems before users do: Our business continuity monitoring identifies early signs of failure, such as increasing latency or replication errors, allowing teams to react before an outage occurs.
- A clear view of risk for management teams: We identify and precisely document every single point of failure (SPOF). IT leaders know exactly which components are protected, which are not, and what the operational impact of each failure scenario would be.
- Seamless maintenance without downtime: Planned maintenance windows, updates, and configuration changes are performed transparently to users. For us, business continuity is not only about protection against failures, it is also about maintaining stable daily operations.
- Complete documentation for audits: System availability history, failover test reports, and business continuity procedures are fully documented and ready for audits in accordance with KNF, DORA, and ISO requirements.
Our services
- Architecture audit for single points of failure: We analyze your existing environment and identify every area where the failure of a single component could interrupt a service. The audit provides a risk map with priorities and architectural recommendations tailored to your infrastructure.
- HA architecture design and implementation: We design redundancy across servers, databases, network layers, and critical services. We implement solutions such as HA clusters and load balancing, all designed for 24/7 mission-critical environments where continuous availability is essential.
- Business continuity monitoring implementation: HA dashboards provide operators and administrators with an immediate overview of the redundancy status of the entire environment, not just information that something has stopped responding.
- Failover testing and validation: Designed redundancy must be tested. We perform controlled tests to verify whether the actual failover time meets the defined Recovery Time Objective (RTO) and Recovery Point Objective (RPO).
- Availability monitoring and SLO-based alerting: Alerts are configured not when a "service is unavailable," but based on the rate at which the environment is approaching an SLO breach. Integration with SLO monitoring provides a complete, real-time view of operational risk.
- Business continuity documentation for regulated environments: For organizations subject to the Polish KNF, DORA, and ISO 22301 requirements, we prepare HA environment documentation, test history, and operational evidence ready for regulatory audits.
If your environment's business continuity relies more on assumptions than documented testing, let's discuss what its real high availability looks like. Schedule a conversation with a Hawatel expert.
