Although security is a broad topic, I want to zoom into a critical aspect: limiting communication between microservices. By default, microservices platforms such as Kubernetes allow unconstrained communication between services.

Versatile Events in Event Driven Architecture

Aug 12, 2021 · 10 min read

Simple applications rely on synchronous request-response protocols. It is one of the most common patterns we encounter every day in applications and websites where you press a button and expect a response. As the number of services increases, the number of synchronous interactions between them increases as well. In such a situation, the downtime of a single system also affects the availability of other systems. Synchronous interaction channels between services Google defines a set of principles and practices for attaining a high Service Level Agreement (SLA) by increasing the SLA of individual services.

Persistent Volume Management and Expansion in Kubernetes with Azure Kubernetes Service

Jul 17, 2021 · 9 min read

Applications or databases running out of disk space are a common issue that the Operations team addresses regularly. This problem has existed since the days we used to host applications on bare metal servers and is still present in virtualized and container environments. However, since we have reached a stage where the compute and storage systems are decoupled from each other, granting additional storage to applications rarely requires updating the application or modifying the underlying application host infrastructure.

Distributed Tracing in ASP.NET Core with Jaeger and Tye Part 2 - Project Tye

May 08, 2021 · 10 min read

In this series: Distributed Tracing with Jaeger Simplifying the setup with Tye (this article) Tye is an experimental dotnet tool from Microsoft that aims to make developing, testing, and deploying microservices easier. Tye’s opinionated nature greatly simplifies the lifecycle of development and deployment of .NET Core microservices. To understand the benefits of Tye, let’s enumerate the steps involved in the development and deployment of the DCalculator application to Kubernetes:

In this series: Distributed Tracing with Jaeger (this article) Simplifying the setup with Tye Modern microservices applications consist of many services deployed on various hosts such as Kubernetes, AWS ECS, and Azure App Services or serverless compute services such as AWS Lambda and Azure Functions. One of the key challenges of microservices is the reduced visibility of requests that span multiple services. In distributed systems that perform various operations such as database queries, publish and consume messages, and trigger jobs, how would you quickly find issues and monitor the behavior of services?

Event-Driven Architecture with Apache Kafka for .NET Developers Part 3 - Azure Event Hubs

Apr 11, 2021 · 10 min read

In this series: Development environment and Event producer Event consumer Azure Event Hubs integration (this article) Azure Event Hubs is a horizontally scalable event ingestion service capable of receiving and processing millions of events per second. It supports Apache Kafka Producer and Consumer API that you can use as an alternative to running a self-managed Apache Kafka cluster. Now you can integrate the Kafka ecosystem applications such as Kafdrop and many others with Event Hubs.

In this series: Development environment and Event producer Event consumer (this article) Azure Event Hubs integration Let’s carry our discussion forward and implement a consumer of the events published by the Employee service to the leave-applications Kafka topic. We will extend the application that we developed earlier to add two new services to demonstrate how Kafka consumers work: Manager service and Result reader service. Source Code The complete source code of the application and other artifacts is available in my GitHub repository.

Event-Driven Architecture with Apache Kafka for .NET Developers Part 1 - Event Producer

Mar 29, 2021 · 12 min read

In this series: Development environment and Event producer (this article) Event consumer Azure Event Hubs integration An event-driven architecture utilizes events to trigger and communicate between microservices. An event is a change in the service’s state, such as an item being added to the shopping cart. When an event occurs, the service produces an event notification which is a packet of information about the event. The architecture consists of an event producer, an event router, and an event consumer.
