SOFTWARE‐DEFINED ENVIRONMENTS
Chung‐Sheng Li, Hubertus Franke · 2021
Software-defined environments (SDEs) bring together software-defined compute, network, and storage and unify the control and management planes from each individual software-defined component. This chapter provides an overview of the vision, architecture, and current incarnation of SDEs within industry. The unified control plane dynamically constructs, configures, continuously optimizes, and proactively orchestrates the mapping between the workload and the resources based on the desired outcome specified by the workload and the operational conditions of the cloud environment. The chapter also demonstrates at a high level how this architecture achieves agility, efficiency, and continuous outcome optimized infrastructure with proactive resiliency and security. The overall framework on continuous assurance of resiliency is directly related to the continual optimization of the services performed within the SDEs, taking into account the value created by the delivery of service, subtracting the cost for delivering the service and the cost associated with a potential failure due to unavailability of the service.
