In today’s digital landscape, cloud-based and microservices architectures have become the standard for building scalable, flexible, and resilient applications. However, this modernization brings new challenges, especially regarding performance. Poor performance not only frustrates users but can directly impact customer retention and business revenue. Therefore, specialized performance testing for these environments is more crucial than ever.
At Software Testing Bureau, with over 30 years of experience at the forefront of software quality, we deeply understand the nuances of modern architectures. We help companies ensure that their cloud-based and microservices applications not only function but deliver an exceptional user experience (CX) under any load conditions.

Traditional monolithic applications presented a relatively contained set of performance challenges. However, the distributed nature of microservices and the elasticity of the cloud introduce greater complexity: AWS Microservices
Network Latency: Multiple services communicating with each other can introduce significant latencies if not properly managed.
Individual Service Scalability: While microservices allow individual components to scale, it’s vital to identify which services are bottlenecks and how they scale under pressure.
Distributed Data Management: Ensuring consistency and performance of data access across multiple services can be complex.
Third-Party Dependencies and APIs: Modern applications often rely on external services, whose performance can impact the overall application.
Dynamic Environments: The elastic nature of the cloud means infrastructure can change, requiring tests that adapt to these changes.
Complex Monitoring and Diagnosis: Identifying the root cause of a performance issue in a distributed system with multiple interconnected services can be challenging.
These challenges underscore the need for a robust and specialized performance testing approach.
To comprehensively address performance in these environments, at Software Testing Bureau, we apply a strategic combination of test types:
Load Testing: Simulate expected user load (and even peaks) to verify how the application and its individual services behave. Identify performance thresholds and potential bottlenecks before they affect real users.
Benefit: Ensures the application can handle the anticipated user volume without service degradation.
Stress Testing: Push the application beyond its normal operational limits to observe its behavior under extreme conditions and its recovery capacity.
Benefit: Determines the system’s robustness and how it recovers from failures or overloads, crucial for cloud resilience.
Soak Testing: Evaluate the application’s stability by subjecting it to the expected workload over a prolonged period.
Benefit: Detects issues like memory leaks or performance degradation that only manifest over time.
Scalability Testing: Verify the application’s ability to scale (up/down or horizontally) in response to varying load levels, a fundamental aspect of cloud architectures.
Benefit: Confirms that the application can efficiently leverage cloud resources to maintain performance as demand grows, optimizing costs.
Spike Testing: Analyze how the system responds to sudden and significant increases and decreases in user load.
Benefit: Prepares the application for unexpected high-traffic events, ensuring stability.
Volume Testing: Focus on the system’s capacity to handle large volumes of data, crucial for applications with extensive databases or processing large information flows.
Benefit: Ensures that data-intensive operations do not degrade overall performance.
Software Testing Bureau designs and implements the appropriate combination of these tests, tailored to your specific cloud and microservices architecture.
Measurement is the first step to improvement. In performance testing for cloud and microservices, we focus on metrics that directly impact CX:
Response Time: The time the application takes to respond to a user’s request. Slow response times are a leading cause of abandonment.
Impact on CX: A delay of just 1 second can significantly reduce conversions.
Latency: The delay in communication, whether between services (in microservices) or between the user and the server.
Impact on CX: High latency translates to a “slow” and frustrating application.
Throughput: The number of transactions or requests the system can process per unit of time.
Impact on CX: Low throughput under load means many users will experience delays.
Error Rate: The percentage of requests that result in errors under load.
Impact on CX: Errors erode user trust and can prevent them from completing their tasks.
Resource Utilization (CPU, Memory, Network, I/O): Monitor how infrastructure components use resources under load.
Impact on CX (Indirect): High utilization can be a precursor to bottlenecks leading to slow response times or failures. Allows for cloud cost optimization.
Scalability: The system’s ability to increase its load-handling capacity by adding resources.
Impact on CX: Poor scalability means that as more users arrive, everyone’s experience degrades.
Optimal performance is directly proportional to a positive user experience. At Software Testing Bureau, we not only identify figures but translate these metrics into the real impact on your users’ satisfaction and retention.

A well-known company managing an international horse racing venue faced critical performance challenges during its most popular events, where thousands of users placed bets and queried race data in real time.
To ensure platform stability and a smooth customer experience during peak demand, the client partnered with Software Testing Bureau to carry out performance tests simulating over 6,000 concurrent users interacting with the system.
🔎 What did we discover?
During the tests, we identified that one key microservice was causing significant delays due to a database-level lock, resulting in several seconds of response time when users attempted to place a bet or access race information.
✅ Results achieved:
The root cause of the performance bottleneck was successfully identified.
The problematic microservice logic was optimized.
The performance tests designed by STB were integrated into the client’s development pipeline, enabling automated validation and monitoring of the impact of new releases.
Thanks to this collaboration, the client now delivers a flawless and responsive user experience even during high-traffic events, ensuring customer confidence and business continuity at mission-critical moments.
Q1: When should I perform performance testing for my cloud applications?
A: Ideally, performance testing should be an ongoing process. However, it’s crucial before major releases, after significant architectural or code changes, before marketing campaigns expected to generate high traffic, and periodically to ensure optimal performance.
Q2: Are performance tests for microservices different from those for monolithic applications?
A: Yes. While the basic principles are similar, testing microservices requires a focus on service interactions, network latency, individual service scalability, and the use of tools that can handle distributed systems. Greater emphasis is needed on contract testing and often on service virtualization to isolate and test components.
Q3: What tools does Software Testing Bureau use for performance testing?
A: We use a combination of industry-leading and open-source tools, selected according to the specific needs of the project. Some
