Validating Containerized Workloads Using Synthetic Monitoring 1

Containerized workloads have become the backbone of modern applications, ensuring scalability and efficiency. As businesses increasingly rely on containers, validating their performance and reliability is crucial. Synthetic monitoring emerges as a vital strategy, providing a proactive approach to validate and optimize containerized workloads in real-world scenarios.


Moreover, the dynamic nature of containerized environments requires adaptable solutions to navigate challenges effectively. Synthetic monitoring not only provides a means to assess performance but also offers insights for continuous improvement. This makes it an indispensable tool for businesses aiming for optimal functionality in their containerized applications.

Synthetic Monitoring for DevOps

Synthetic monitoring is a technique that enables teams to simulate virtual patterns. The patterns can be anything, like website traffic, network latencies, dummy data, etc. The simulated patterns are very crucial to test and debug complex solutions. Introducing simulated patterns into test environments makes flagging of the unknowns possible. This allows teams to derive solutions beforehand to handle unknowns in live environments.

Leveraging synthetic monitoring techniques with DevOps yields greater confidence in delivering stable solutions. Let us uncover how synthetic monitoring helps deliver reliable and scalable solutions.

3 Synthetic Monitoring Approaches to Verify Containerized Workloads

While application features and integrations often excel in local environments, issues like defective responses and inaccuracies can arise under heavy production workloads. Identifying and isolating these bottlenecks is essential for ensuring optimal performance in distributed scenarios.

Synthetic monitoring becomes instrumental in simulating these conditions, allowing for a comprehensive understanding of application behavioral patterns under diverse circumstances. Let us look at the following monitoring approaches to verify containerized workloads:

Emulating the Network Conditions

Distributed and microservice-oriented solutions rely on networks for communication and data transmission. Various network protocols work asynchronously to ensure the performance and scalability of these solutions. Achieving optimal results involves carefully mapping out the network elements.

When architecting network conditions, it’s crucial to consider all communication scenarios within the application, as different protocols (HTTP, HTTPS, TCP, UDP, etc.) can have varied effects on components. Synthetic monitoring proves valuable in simulating real-world scenarios, achieved through the use of various toolsets like Netem or Fiddler for emulating network conditions.

Third-party proxy providers introduce latency and bandwidth constraints, while TC, an inbuilt command for configuring traffic control on Linux instances, plays a role as well. Integrating network emulation into synthetic monitoring instills confidence in the application’s ability to withstand diverse network conditions.

Simulating Distributed Tracing and Dynamic Service Discovery Mechanisms

Containerization enables the isolation of features or code from the underlying OS. Most features are bundled as microservices, communicating together. We know that microservices communicate while sharing data and state. This communication relies on the factor that microservice instances are discoverable across environments. Also, the communication requests are efficiently getting traversed across the microservices.

Surge-based addition or removal of microservice is common. For example, Kubernetes adds, removes, or modifies the microservices as part of fail-over, remediation, and recovery mechanisms. When the refactoring occurs, existing microservices must redirect traffic and requests accordingly. However, Kubernetes takes care of network routing with sub-second latencies.

Complex systems face challenges when misconfigurations create undiscoverable microservices that reject incoming requests. The occurrence is one in 1000. But when developing mission-critical or high-availability systems, testing every possible scenario is critical. With synthetic monitoring, validation of resiliency, scalability, and performance is done at scale. Open-telemetry for distributed tracing and Kubernetes etcd for service discovery are free and efficient choices.

Injecting Security Testing Patterns

The security posture is of high priority when developing distributed microservices. Every interaction has to be stable and secure. Small discrepancies in security protocols can turn into deep legal and compliance issues. Every aspect of the microservice has to be validated for security. However, sometimes unintentional mistakes enter live environments. For example, mistakes like unpatched instances with the latest security updates, unwanted port exposure, or unauthorized access provisioning are common.

Injecting security simulations into the microservices allows for proactive identification and rectification. Synthetic monitoring plays a pivotal role in enabling teams to test microservices under different scenarios. The simulative validation ability allows teams to apply robust security measures to recover and remediate anomalies. Tools like OWASP ZAP can help simulate security measures while building distributed microservices.


Containerization brings significant advantages to distributed workloads, and synthetic monitoring plays a crucial role in preparing containers and distributed microservices to adapt to changing requirements. Incorporating synthetic monitoring into an enterprise monitoring strategy can lead to long-term benefits. Specifically for microservices, simulated monitoring enables teams to validate various aspects such as network functionality, security, performance, scalability, and more.

It allows teams to assess how applications perform under different network conditions, including the passing of data and states with varying latencies. Additionally, it helps in understanding how information traverses across the network, whether new instances scale as intended and their discoverability. Synthetic monitoring proves valuable in validating numerous checks to ensure the smooth functioning of microservices.
