In ourprevious article, we discussed the high-level architecture for addressing performance, one of the non-functional requirements (NFRs) in microservices architectures. This article dives into some key design considerations around performance usingApache Kafkaas the event backbone. Performance modeling Pe...
but want to provide individual measurements. We are using this method to track the KPIs for our microservice pipeline. We attach the ingestion timestamp as a Kafka header to each message and can track the time spent throughout the pipeline...
I use Apache Kafka to represent the event bus in the pictures below, but don’t worry if you run a different stack. The same concepts still apply. Choreographed microservices Let’s assume the following services and events form your choreographed system: Camunda Figure 1. Event-driven ...
asyncfunctionbootstrap(){constapp=awaitNestFactory.create(AppModule,{bufferLogs:true,});appStartup(app);awaitapp.startAllMicroservices();awaitapp.listen(config.get('app.port'));};voidbootstrap(); To test the application, I use the @testcontainers/kafka package. With the help of this, I cre...
The demand formicroservicesis multiplying with each day passing. When you decide to develop an application as a set of microservices, you must ensure how the client will interact with your microservices. But the question is, why use a microservice architecture pattern over a monolithic application...

Kafka (Managed in AWS MSK) Kubernetes Nginx (ingress controller within Kubernetes) Why Did We Use JMH? JMH(Java Microbenchmark Harness) is a library for writing benchmarks on the JVM, and it was developed as part of the OpenJDK project. It is a Java harness for building, running, and...
The problem is that IServiceScopeFactory is not found when attempting to create my service. How can i register IServiceScopeFactory during startup?Currently, my Startup.cs looks like this https://pastebin.com/aGaAhtVDP.s. I also use SimpleInjector in my app....
Kafdrop helps us in solving this problem. It gives us a simple, lightweight, and easy-to-use User Interface where one can not only see the required information but can also create and delete Kafka topics. Features View Kafka brokers- topic and partition assignments, and controller status ...
Kafka Streams Kafka Streams is a client library (KStream) that developers adopting the pub/sub model use to build applications and microservices based on Kafka clusters datastores. Messages arrive as a key-value pair, analogous to a two-column row in SQL database terminology. The KStream libra...
