Auditing in Microservices

In software, auditing means tracking user or system activities for various needs, such as business or security. An example would be - user X tried to access resource Y. When I encuntered issues with auditing at my current company, I looked for solutions online, most of which, were either vague, lackluster or plain simple. That is why, after having implemented and dealt with auditing at scale, I would like to share my thoughts. In this post, I will show the various methods for implementing auditing together with code examples and pros and cons.

Implementing Ports and Adapters

There are different architectures that allow you to keep focus on your business domain and allow for fast paced development and changes. Examples would be: Clean Architecture, Onion Architecture and Ports and Adapters (also called hexagonal).
In my previous post, I talked about Clean Architecture and how it helps get your code more modular and developer friendly after a somewhat short learning curve. After joining a new team, I noticed Clean Architecture did not really settle and the team found it to be somewhat over abstracted, so I decided to play around with a variation of Ports and Adapters.
In this post I will show what is Ports and Adapters and how I implemented it in Golang. Github repo is available here.

What Are Microservices

After having written and implemented several microservice architectures, I wanted to have a go at explaining microservices from my point of view and share my insights. In this post I will explain what are microservices, what are their pros and cons, how they communicate and the different approaches towards building microservices.

Context Maps in Domain Driven Design

Ideally, it would be great to have a single place that incorporates all of our models, but in reality, our systems fragment to multiple models and we need to understand how to approach building them in way that allows future changes quickly.
Strategic Domain Driven Design is a high level approach to distributed software architecture and is an essential part of DDD. One of its features is context maps, which allows grasping the different relationships between bounded contexts (a boundary within which the ubiquitous language is consistent) and gives the teams a better understanding on how they affect each other. In this short post I will introduce you to the basics of context maps.

Implementing Clean Architecture

Last year, I had the opportunity to design a new project at work and since I had just finished reading Robert Martin’s Clean Architecture I thought to myself, why not implement it on that project ? One of the reasons, except my usual I have to implement this cool thing right away! was that working on legacy systems in the company was accompanied with the good ol’ big ball of mud code. The purpose of this post is to show you how can one implement Clean Architecture in practice and still understand it years from now, whether you work alone or in a team. Everything shown will be written in Typescript on Node.js using Object Oriented programming paradigm. All of the code will be available here
