As cloud-native development continues to evolve, containers have become integral to modern software delivery. While Docker has popularized containerization, it often introduces overhead and complexities that may not fit every use case. This talk will focus on the fundamentals of container architecture and demonstrate how to build a custom container from scratch, avoiding the pitfalls associated with traditional container solutions.


In the era of cloud-native development, containers have become essential for efficient software delivery. However, while Docker offers significant advantages, it also introduces overhead and complexities that may not suit all organizations, especially those with critical systems. This talk will take a deep dive into the architecture of container systems, demonstrating how to create a custom container without relying on Docker.

We will begin by exploring how containers function, focusing on the foundational technologies and their interactions with host systems. From there, we will provide a hands-on approach to building a lightweight container from scratch, detailing methods for integrating applications directly into the container, akin to Dockerfile practices, while avoiding unnecessary features.

The session will also include real-world case studies that examine the practical implications of using custom containers, highlighting performance benefits and the challenges faced during deployment in high-load environments. We’ll share insights into the design decisions made, the trade-offs considered, and best practices for effectively managing containerized applications.

This session is tailored for software engineers, system architects, and DevOps professionals eager to explore the intricacies of container technologies and discover alternative strategies for optimizing performance in large-scale systems. Join us to unlock the potential of custom containerization and enhance your understanding of the underlying technologies that power modern applications!
