Applying Software Defined Methodologies to Software Computing

摘要

Computing systems and services are now required to provide services with quality, intelligence, accuracy, adaptation, and effectiveness to satisfy the demands of users. Most of the existing systems are executed with fixed computing logic and rules without the flexibility and smartness to react the dynamic changes of computing situations and environment. Information technology is moving toward a new "software-defined" (SD) era that makes the software more "in command" of a greater range of devices and hardware systems for computing, storage, transmission, and networking. Software defined systems refer to a collection of enabling software technologies that are emerging in the information technology arena. Examples include Software Defined Networking (SDN), Software Defined Security (SDSec), Software Defined Data Center (SDDC), Software Defined Storage (SDS), and Software-Defined Radio (SDR). Considering their unique features, software development of these systems raises new challenges. In this paper, we plan to design and develop Software-defined Methodologies (SDM) which will be applied to software life cycle. With the support of SDM, we believe SD systems will contain the intelligent characteristics, such as security, reliability, QOS assurance, adaptability, low power consumption, situation awareness... etc.
