Evolution of cloud data center models for Autonomic and agile elastic resource provisioning
Abstract
The software industry is in a very fluid nature in this present decade whereas companies have modified their software specifications regularly to adapt with recent context. When, the organization has demands not only for quick delivery of software products and but also recognizes specifications as well. Agile methodologies are quite anomalous in the software industry based on this idea which emphasizes evolutionary design and delivery, iterative approach, fast and flexible reaction to alteration and proactive planning. Moreover, elasticity is frequently implemented on the platform of cloud and data centers with virtualization using auto-scaling mechanisms which provided an automated resource decisions in accordance with specific infrastructure metrics value. The auto-scaling mechanisms have been performed dynamically for modifying the changes in workload using self-regulating provisioning and de-provisioning of resources.Therefore, the availability of resources corresponds to as closely as possible for the actual market demand in each situation.In addition, the problem faced in many IT environments is unable to deliver the level of responsiveness that businesses demand. Thus, managing disparate and silo infrastructure are also resource-intensive, forcing IT staff to waste valuable time and effort fighting fires and performing manual, repetitive tasks, instead of using their knowledge and expertise in contributing to more strategic, innovative business initiatives. This paper has focused to assist business stay competitive and IT organization requires a modern data center which as the ability to provide the agility, security, and scalability required for driving innovation and growth in the digital environment. This proposed ultra-modern infrastructure is evolved based on a software-defined, composed architecture that spans compute, storage, networking, and security with unified management. This architecture enables an enterprise-ready, high-performance data center which is highly agile, cost efficient,energy efficient, elastic and secured. Hence, the evolved ultra-modern infrastructure of composed architecture is compared with existing modern data center infrastructure with various parameters like energy efficiency, maximum response time and average renting cost.
