Optimized Resource Allocation & Task Scheduling Challenges in Cloud Computing Environments

Cloud computing refers to Internet based development and utilization of computer technology, and hence, cloud computing can be described as a model of Internet-based computing. Actually, it is a style of computing, in which dynamically scalable (and mostly virtualized) resources are provided as a service over the Internet. The concepts behind cloud computing incorporate Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS), respectively. In today’s rather challenging economical environment, the promise of reduced operational expenditure, green computing advantages, along with more reliable, flexible, and scalable application services made cloud computing a rather sought-after technology. The actual Cloud Computing definition by the National Institute of Standards and Technology is: “Cloud computing is a model for enabling convenient, ondemand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”
