All about memory

As hardware grows more powerful and application density increases, optimising Linux-based environments requires more than default kernel and Kubernetes settings. This talk examines the need for careful tuning, fine-grained workload isolation, and specialised capabilities to prevent noisy-neighbour effects. It also discusses the importance of testing kernel changes through controlled deployment processes, given the interconnected nature of Linux subsystems. Finally, it highlights how application developers can improve performance by considering memory access patterns and code organisation.
