State and local agencies that rely on geographic information system (GIS) applications like ArcGIS for essential services must prioritize application resilience, especially during emergencies when performance issues can have significant consequences. Advanced observability solutions play a crucial role in eliminating blind spots in application performance, offering IT teams the ability to proactively address potential outages and enhance the citizen experience by ensuring optimal application availability and performance. Application Performance Monitoring (APM) is essential in this context, providing insights into complex hybrid environments and enabling staff to improve both customer experience and operational efficiency. Full-stack observability extends these capabilities by offering comprehensive, real-time insights into application health, infrastructure, and database performance, helping IT teams swiftly address issues before they impact users. Furthermore, automated vulnerability detection and runtime analysis help secure applications against growing cybersecurity threats, ensuring a safe digital transformation. By integrating these tools, agencies can improve citizen services and employee satisfaction while managing the complexities of modern IT environments effectively.
