Overcoming Event Size Limits with the Conditional Claim-Check Pattern in Event-Driven Architectures
In today’s technological age, we typically build our application solutions on event-driven architecture in order to make them as scalable, resilient, and flexible as possible. While event-driven architecture sounds good, it also brings along many complexities and limitations. In my previous articles, I also tried to touch on topics such as the best practices we […]

How to Order Events in Microservices by Using Azure Service Bus (FIFO Consumers)
Sometimes there are some scenarios that we can’t avoid or have to implement even though we know their complexity or drawbacks. I think, having a need to process some events/messages that are relevant to each other in a certain order (that they are published) in a distributed environment is also one of them. For example, […]

Providing Atomicity for Eventual Consistency with Outbox Pattern in .NET Microservices
As we know, adapting to microservice architecture has many benefits, but unfortunately, it also has some challenging points. Especially on the data consistency side. For example, in the monolithic world, we can use ACID database transactions to easily perform multiple operations in a consistent way. However, in the microservice world, as transactions need to be […]

How Should My Event Be Designed? Some Thoughts on Event-Based Systems
As we know, software development doesn’t end easily especially in today’s world. In addition to developing the software, it is one of our biggest problems and responsibilities to ensure that it works properly and consistently. As we can imagine, from time to time those kinds of needs lead us to microservice architectures, event-based systems and […]

Implementation of Choreography-based Saga in .NET Microservices
In today’s technology era, almost all of us talk about microservices and try to develop applications. When we just talk about microservices before get started to implement, everything might seems very clear and easy to implement. But, especially when the topic comes to distributed transaction management, then things start to get complicated. Because we need […]

Understanding SOLID Principles, keep calm! For Cloud-Native Applications
In this article, I want to mention about the SOLID principles but this time for cloud-native applications. As we know, SOLID principles are undoubtedly one of the most important sets of principles in the object-oriented software development world. We are generally trying to develop our codes based on the SOLID principles when we develop applications, […]

Distributed Tracing with OpenTracing API of .NET Core Applications on Kubernetes
Distributed tracing is a great method in order to be able to address and monitor where we have a performance problem in our applications that we designed as microservice architecture. In other words, it is a necessary method in order to get some answers such as which request go where, how much time do a […]
