Currently, debugging of microservices is often assisted by OpenTracing, which helps in tracing of a transaction or workflow for postmortem analysis and more recently by service meshes like Istio, which monitor the network to identify latency problems in real-time. The state of the application is spread across multiple microservices, and it’s hard to get a holistic view of the state of the application. “ Debugging microservices applications is a difficult task. Together, these properties can make transactions difficult to step through.

As such, microservices can be written in different languages, and may be running across several different nodes. The fine-grained approach to developing microservices lets developers choose the best language and framework for a specific job. Moreover, s ervices often interact with one another intermittently. Communication between services is asynchronous and not reliable, making errors difficult to reproduce. Microservices applications present unique challenges. Technical challenges with microservices applications

It is important to knowing the right techniques and to deploying the right debugging tools in order to reduce time and money spent to correct software code. Importantly, identifying the root cause of issues in microservices application can have a direct business impact. In fact, 40% 2 to 90% 3 of total software costs of are typically incurred after launch. For this reason, troubleshooting is more difficult in a microservices environment, The main problem with debugging and finding the root cause in a distributed system is being able to recreate the state of the system when the error occurred so that you can obtain a holistic view. In contrast, a microservices application can be composed of hundreds of processes. It is easy to attach a debugger to this process to have a complete view of the runtime state of the application. Expect challenges and changes on the microservices journeyĪ typical traditional monolithic application consists of a single process. This article explores several approaches to deploying tools to debug microservices applications on a Kubernetes platform like Red Hat OpenShift, including OpenTracing, Squash, Telepresence, and creating a Squash Operator in Red Hat Ansible Automation. A microservice is a small, independently deployable, and independently scalable software service that is designed to encapsulate a specific semantic function in the larger application l. This proliferation of microservices applications generates new problems, which requires a new approach to managing problems. Microservices have become mainstream in the enterprise.
