Performance Testing Services
As digital products become more feature-rich and increasingly distributed across hybrid and multi-cloud environments, performance and resilience can no longer be treated as secondary concerns. Our performance engineering and site reliability services help organisations manage complexity, eliminate bottlenecks, improve scalability, and strengthen application resilience across modern software ecosystems.
Speed and Reliability as a Key Asset
At IGS Global, we help organisations embed performance, reliability, and resilience into the software development lifecycle from the outset. Our specialists provide performance testing, resilience assessment, SRE enablement, observability support, and engineering advisory services that help reduce operational risk and improve service quality.
Unlock Additional Revenue
Strong application performance has a direct impact on customer experience and commercial outcomes. Faster, more reliable digital experiences improve satisfaction, strengthen loyalty, and support better conversion rates by helping users complete critical journeys without friction or delay.
Meet Today's Demands
In today’s always-on digital landscape, organisations need applications that remain responsive, stable, and scalable under changing demand. Performance and resilience engineering helps reduce latency, optimise infrastructure use, and deliver the dependable experience customers now expect across channels and platforms.
Reduce Operational Costs
Investing in performance and resilience early helps reduce the cost of downtime, incident recovery, support overhead, and repeated troubleshooting. It also gives teams better visibility into system behaviour, enabling faster issue resolution and more efficient operations over time.
How Can We Help?
As applications expand across services, integrations, and cloud environments, our performance and resilience engineering services help organisations reduce complexity, address root causes of instability, and improve software robustness across the delivery lifecycle.
Our performance testing services help you validate whether systems can meet expected demand, remain stable under pressure, and continue to support key business journeys as usage grows. We define testing objectives, build the right test approach, create realistic scenarios, execute tests, and provide clear findings with prioritised recommendations.
- Define performance testing objectives
- Develop a performance test strategy and plan
- Create and execute scripts and scenarios
- Report findings with actions and recommendations
- Support both project-based and iterative delivery models
We help organisations assess and improve the maturity of their performance testing and performance engineering capabilities. From process review to roadmap creation, our consultants support optimisation efforts that make performance a repeatable and measurable capability rather than a one-time activity.
- Improve and mature performance processes
- Review current testing and engineering capability
- Define an optimisation roadmap
- Establish continuous measurement
- Advise on tools and licensing
- Support rollout and adoption
When applications underperform in production, teams need more than issue detection. They need focused diagnosis and practical remediation. Our application tuning support helps identify root causes, prioritise quick wins, and work alongside technical teams to improve performance through targeted optimisation and ongoing measurement.
- Diagnose root causes of production performance issues
- Identify quick wins and an optimisation roadmap
- Work with technical teams to resolve issues
- Measure improvements continuously
Reliability is built through preparation, not reaction. Our resilience engineering services help organisations embed site reliability practices into delivery lifecycles, validate systems against resilience best practices, and test recovery behaviour under failure conditions using structured resilience and chaos engineering methods.
- Build an approach and framework for SRE in delivery lifecycles
- Review architecture against resilience best practices
- Execute resilience tests with controlled failure injection
- Define chaos testing strategy, tooling, and implementation
- Measure resilience based on recovery speed and end-user impact
Observability is essential for understanding system behaviour and responding before issues become incidents. We help organisations consolidate signals from logs, tracing, infrastructure monitoring, real-user monitoring, and synthetic monitoring so teams can detect anomalies faster, reduce MTTR, and make more informed operational decisions.
- Collect and unify observability data across key sources
- Enable anomaly detection and alerting
- Generate insights to improve experience and reduce MTTR
- Support adoption of leading vendors or open-source observability options

IGS's Foundations for Excellence in Performance Engineering & SRE
Our approach to performance engineering and site reliability is grounded in business relevance, technical partnership, and measurable improvement. We work with clients to understand what performance and resilience mean in their context, then build practical solutions around those needs.
Assessing Business Impact
We begin by understanding how performance and resilience influence customer experience, operational continuity, and commercial outcomes so engineering priorities are aligned with real business risk and opportunity.
Strategic Problem Framing
We define challenges within the client’s business and technology context, ensuring that the solutions we design are relevant, actionable, and aligned with broader strategic objectives.
Shared Responsibility
We work with technical teams to improve performance and resilience collaboratively, focusing not only on identifying issues but also on helping implement practical solutions that teams can sustain.
Evidence-based recommendations
We help teams gather the right data to uncover root causes, validate proposed changes, and prove that the resulting improvements are producing meaningful outcomes.
