Reliable Connection to Address Lookup API

The API utilises a robust JSON-based data structure, delivering low latency (approximately 177 milliseconds) and seamless scalability. Built on Microsoft Azure’s cloud-native architecture—engineered for 24/7 availability—the system automatically provisions resources as demand increases, ensuring consistent performance under varying load conditions. High availability and data integrity are achieved through the use of Azure App Services and Azure Load Balancer. Auto-scaling groups dynamically allocate compute resources based on traffic volume, while redundancy and failover strategies ensure uninterrupted service during maintenance windows or unexpected outages.

This architecture has been stress-tested to support up to 36,000 hits per minute per server—three times the projected baseline traffic. In the event of service degradation or node failure, traffic is automatically rerouted to healthy instances, maintaining service continuity without disruption. The API is available 24/7/365.

The average API response time on initial execution is approximately 380 milliseconds and 177 milliseconds once the session information (SSL/TCP cert and DNS) is cached after the first run.

Performance Monitoring and Real-Time Alerting

We employ real-time performance monitoring using Azure Monitor, Application Insights, and integrated alerting mechanisms. These tools track throughput, latency, memory usage, and API health across all services. Proactive alerts are configured to notify operations teams of any performance anomalies or downtimes, ensuring immediate intervention.
