Case Study Summary
How did Clear Sky help the New York Power Authority validate enterprise access at scale?
Clear Sky used its Stratos platform to stress-test NYPA's internal web applications and file systems, simulating 25,000+ concurrent user sessions across physical, virtual, and cloud infrastructure.
The testing confirmed NYPA's internal systems could handle thousands of simultaneous users without degradation and delivered actionable insights within a single one-hour test window — with zero disruption to live operations.
Outcomes at a Glance
The Challenge
Can Our Internal Systems Sustain Thousands of Simultaneous Users?
As remote access usage suddenly expanded, NYPA faced a critical question it couldn't answer with its existing tools. With growing reliance on remote VPN-based access and internal web applications across distributed teams, traditional testing approaches could not realistically simulate the scale, concurrency, and real-world user behavior required to answer these questions with confidence.
How Clear Sky Helped
Scalable Internal Application Testing Powered by Stratos
Progressive Load Scaling
Simulated virtual users in controlled increments—from hundreds to thousands—to identify performance trends and capacity thresholds before real usage hit those levels.
Internal Application-Centric Testing
Focused on actual usage of internal systems, including web applications and file services, rather than abstract infrastructure metrics—validating what users actually experience.
Scenario-Based Traffic Modeling
Executed a range of scenarios—low, typical, and peak usage—by combining user interactions and file transfer workloads to mirror day-to-day and surge conditions.
Rapid Feedback Cycles
Delivered actionable insights within a single one-hour test window, enabling immediate understanding of system readiness without prolonged assessment cycles.
Continuous Monitoring & Insight Generation
Captured performance data across physical, virtual, and cloud environments to provide a unified view of system behavior under load—eliminating infrastructure blind spots.
Results & Business Impact
From Uncertainty to Clarity — Quickly and Decisively
Strategic Outcome: By leveraging Stratos, NYPA gained a real-world, application-centric understanding of system performance under extreme conditions—validating true user experience, simulating enterprise-scale access patterns with precision, and making informed decisions about scalability and risk mitigation. Stratos transformed performance testing into a strategic capability.
