This retrospective by Marc Olson offers a detailed look at the evolution of AWS Elastic Block Store (EBS), tracing its journey from a simple network-attached block storage service launched in 2008 to a massive, distributed SSD-based system now handling over 140 trillion operations daily. The post highlights key lessons learned in performance engineering, organizational structure, and continuous incremental improvement, illustrating how EBS overcame challenges like noisy neighbors, hardware transitions from HDDs to SSDs, and the need for robust measurement and instrumentation to deliver ever-lower latency and higher reliability for AWS customers.

Understanding how to secure Linux containers requires a deep dive into tools like seccomp, which can restrict the system calls available to containerized processes. In this technical guide, the fourth installment of the Container Internals Series breaks down how seccomp filters work, their real-world impact on container security, and practical steps to implement custom seccomp profiles for hardened deployments.

Upgrading from Node.js 18 to 20 brought unexpected performance impacts to a Kubernetes-deployed service, as detailed in this technical recap. The experience-driven story reveals how changing memory reservations on Kubernetes pods can shrink Node.js heap spaces—specifically the "new space"—triggering heavier garbage collection and higher CPU load, and how adjusting the --max-semi-space-size parameter restored both speed and stability.
