📝 Description

The video explains the concept known as the Noisy Neighbour Problem within cloud and distributed systems. This issue describes a scenario where the performance of one application or service degrades unexpectedly, despite the code base itself functioning correctly. The explanation utilizes a real-life analogy to illustrate how resource contention occurs in multi-tenant environments, such as shared servers or Kubernetes nodes. It details the underlying reasons why resource contention manifests in these architectures and identifies common real-world manifestations of this system design antipattern. High-level mitigation strategies for managing this impact on performance are also presented.

Coverage focuses on fundamental system design principles relevant to backend engineering and cloud computing. The content serves as documentation for system design concepts frequently encountered in modern software engineering practices.
