Endurance testing for
always-on enterprise systems
Detect slow-burn failures before they become outages. Validate long-term reliability for systems that never stop.
Why systems fail over time
Load tests run for minutes. Production runs for months. The failures that matter emerge after hours, not seconds.
Memory leaks and resource exhaustion
Gradual memory growth that passes short tests but crashes after hours of operation.
Performance degradation over time
Response times that creep up as caches fill, queues grow, and connections accumulate.
State corruption under sustained load
Data inconsistencies that only emerge after thousands of transactions accumulate.
Background jobs accumulating failures
Retry queues that grow silently until they overwhelm the system.
Long-running workflows breaking
Multi-hour workflows that fail at hour six, not minute six.
Issues that only appear after days
Connection pool exhaustion, certificate rotations, and time-based edge cases.
How Zof validates endurance
Continuous validation under sustained real-world load. Detection of degradation before customers feel it.
Automated long-duration test execution
Configure tests to run for hours or days. Zof manages execution, restarts, and state persistence across extended validation windows.
Continuous monitoring during sustained runs
Real-time tracking of memory, CPU, connections, and response times throughout the entire test duration. Spot trends before they become failures.
Degradation trend detection
Identify gradual performance decay that traditional pass/fail tests miss. Catch memory growth, latency creep, and resource leaks early.
Extended workflow validation
Validate complex, stateful workflows over their full operational lifecycle. Ensure multi-step processes remain stable after thousands of iterations.
Evidence of stability, not assumptions
Generate concrete proof that systems remain healthy under sustained operation. Replace hope with data-backed confidence.
Reliability infrastructure, not tooling
Endurance validation built for teams that operate critical systems. Not another testing tool. A core pillar of reliability engineering.
Built for always-on systems
Designed for systems with zero-tolerance for downtime. Validate 24/7 operational stability before production.
Complex, stateful workflows
Handles distributed transactions, saga patterns, and multi-service orchestrations that span hours or days.
CI/CD and SRE integration
Fits into existing reliability practices. Schedule long-duration runs alongside deployment pipelines.
Prevents slow-burn outages
Catch the failures that accumulate over time before they escalate into production incidents.
Built for teams that can't afford downtime
From SRE teams to enterprise leadership, endurance validation protects what matters most.
SRE Teams
Early degradation detectionCatch memory leaks, resource exhaustion, and performance decay before they trigger on-call alerts.
Platform Teams
Proof of long-term stabilityValidate that infrastructure can sustain production load over time. Evidence, not assumptions.
Engineering Leaders
Fewer unexpected outagesReduce the outages caused by gradual degradation. Sleep better knowing systems are validated for the long haul.
Enterprise Organizations
Improved uptime and trustStrengthen SLAs with confidence. Build customer trust through proven reliability over extended periods.
Endurance validation workflow
Continuous validation from start to actionable insights. Proof of long-term stability at every step.
