Agile Quality in the Cloud Leading Azure RDOS Testing and Release Management

Abstract

Microsoft Azure’s cloud platform is based on the Red Dog Operating System (RDOS), one of the world’s first cloud
operating systems for large-scale, multi-tenant cloud deployments. RDOS provides a stable, scalable, and highly automated
infrastructure for application and service deployment and management. It employs cutting-edge features such as the
fabric controller to provision, load balance, manage capacity, and provide fault tolerance without any human intervention.
RDOS is essential to coordinate virtualized computing, storage, and networking resources from Azure’s worldwide
data centres. RDOS makes up for the limitations of traditional operating systems within cloud systems, enabling high
availability, seamless scalability, and dynamic resource provisioning. RDOS also meets global data residency and security
requirements, decouples hardware management complexity, and enables Azure to deliver uninterrupted service even in
hardware failure or loss. RDOS provides auto-management of infrastructure, higher reliability, economy, and support for
multiple services and programming models. This essay critically analyses RDOS from its internal working processes and
architectural foundation to its application in the provision of cloud services today, with emphasis on its performance and
quality, program and collaborative management approaches, and its capability to support Azure’s automation, scalability,
and resilience.
