Tech notes of hands-on software architects

This article introduces cache partitioning strategies for distributed systems, focusing on how to efficiently manage large volumes of data and heavy traffic. It explains the importance of partitioning, compares replication and partitioning approaches, and discusses key techniques like consistent hashing to balance load across cache nodes. The post also covers how to decouple cache partitioning from application logic using tools like Ketama and Twemproxy, with practical guidance for Kubernetes environments.

In this blog post, we explore how embracing slow, analytical thinking, supported by Architecture Decision Records, can lead to more deliberate and durable architectural decisions.

In this short note, we share our thoughts on a panel discussion featuring Daniel Terhorst-North, who compared software development to surgery.

This blog post provides a comprehensive guide to effective planning for Site Reliability Engineering (SRE) projects, balancing long-term initiatives with operational responsibilities. However, the principles and practices discussed here are not limited to SRE. They can be applied to any software engineering project, making them relevant for a wide range of teams and organizations.

In this article, we’ll share our experiences with leveraging AI to efficiently generate high-quality Architecture Decision Records. We'll discuss practical techniques, provide examples, and outline the benefits and challenges we've encountered.

Recently, our team embarked on a major architectural transformation - moving from a monolith to a services-based architecture. As expected, the engineers on our team understood the rationale behind this shift, but the business stakeholders had concerns.

The Transactional Outbox Pattern is widely discussed in theory. In this blog post, we present a reference implementation of the pattern and provide a hands-on guide that bridges the gap between theory and real-world application.

After a short break from blogging, we are back with fresh insights from our recent presentation at the Poznań Java User Group about the practical DevOps approach.
