In my previous article, I mentioned that transport independence is the basis of microservices and is necessary to develop sustainable microservice architectures. You can reach my previous article with this link. There are two different aspect of a message interaction in microservices: Synchronous/Asynchronous (solid / dashed line) : The message…

One of the main features of microservices is their ability to communicate with each other but this feature does not require that the microservices know each other. Microservices should be a black box and stateless. Explicit coupling is the result of ignoring these two concepts. …

If I had an hour to solve a problem I’d spend 55 minutes thinking about the problem and five minutes thinking about solutions. Albert Einstein You should deeply understand and describe the problem as clearly as possible before finding and implementing the solution. At this point, you can use specific…

#1 The tech leads are the bridge between technical stakeholders and business stakeholders. So we must build a clear and robust communication between our stakeholders. It is not all about technical decisions, like system design, an interfaces, allocating responsibilities, design patterns , performance optimization, security, usability etc. It is all about…

The Cap Theorem can be summarized with three words; strong consistency, availability and partition tolerance. As you know, You must pick two out of three. Unfortunately, You actually have only two options — not three. You can not be avoid or defeat network faults in any way. So, you can…

Distributed Systems is a not a simple concept based on software architectures (especially micro services). Physically, a distributed system is an ensemble of physical machines that communicate over network links. In other words, a distributed system is composed of software processes that communicate via IPC mechanisms and are hosted on…

We launched the new checkout ecosystem “Erebor” after a few months ago in Hepsiburada. In this article, I will talk about what we have experienced during in this micro-service transformation. “A software ecosystem is the interaction of a set of actors on top of a common technological platform that results…
