Last time, we talked about 8 fallacies of distributed computing and why our systems end up being more complex than we ever imagined. In our last conclusion, we mentioned that two nodes already have a lot of aspects to consider, let alone a microservice architecture. Microservice architectures have many additional…

Know the three main items of a good design review — This article will take backend development as an example, but the same concepts can be applied to various fields. Before explaining how to prepare a good design review, let’s first introduce what a design review should have. As an architect, I’m going to tell you what I want to see. …

Explained with a code sample — This article is the last of this series. We have already described the problem encountered in data-oriented design. In this article, we will introduce a better way to tackle a feature requirement. We continue the previous example, a sign-in mission, and try a different…

Software design is an evolving process. Every large system starts from a tiny system. When a problem is encountered in the existing architecture but cannot be solved, the system will begin to evolve. Every evolution is accompanied by some technical selections. What problems should be solved? What price will it…

For example, when a commercial website is sending out promotion SMS, shortening the URL can effectively save the cost of SMS. In addition, short URL services involve…

Writing maintainable unit tests — I have introduced property-based testing before and mentioned that property-based testing is designed to cover the shortcomings of example-based testing. Since it is difficult to generate examples to hit various edge cases and boundary conditions, we generate a large number of examples in an automated way to cover the tests…

Make an easy management data pipeline — Airflow is one of the great orchestrator today. It is a highly scalable and available framework for orchestrating, and more importantly, it is developed in Python. Therefore, developers can develop in Python based on the various operators provided by Airflow. In addition, the Airflow community is quite active, and many…

A good service template is the top priority — When we talk about microservices, we have to understand that the number of services within the microservices architecture is significant; in some large organizations where the number of microservices is even in the tens of thousands. If each service setup has to go through a complicated programming process, then it…
