A service-oriented hybrid access network and clouds architecture
Many telecom operators are deploying their own cloud infrastructure with the two-fold objective of providing cloud services to their customers and enabling network function virtualization. In this article we present an architecture we call SHINE, which focuses on orchestrating cloud with heterogeneous access and core networks. In this architecture intra and inter DC connectivity is dynamically controlled, maximizing the overall performance in terms of throughput and latency while minimizing total costs. The main building blocks are: a future-proof network architecture that can scale to offer potentially unlimited bandwidth based on an active remote node (ARN) to interface end-users and the core network; an innovative distributed DC architecture consisting of micro-DCs placed in selected core locations to accelerate content delivery, reducing core network traffic, and ensuring very low latency; and dynamic orchestration of the distributed DC and access and core network segments. SHINE will provide unprecedented quality of experience, greatly reducing costs by coordinating network and cloud and facilitating service chaining by virtualizing network functions.Peer ReviewedPostprint (author’s final draft
Autonomic Cloud Computing: Open Challenges and Architectural Elements
As Clouds are complex, large-scale, and heterogeneous distributed systems,
management of their resources is a challenging task. They need automated and
integrated intelligent strategies for provisioning of resources to offer
services that are secure, reliable, and cost-efficient. Hence, effective
management of services becomes fundamental in software platforms that
constitute the fabric of computing Clouds. In this direction, this paper
identifies open issues in autonomic resource provisioning and presents
innovative management techniques for supporting SaaS applications hosted on
Clouds. We present a conceptual architecture and early results evidencing the
benefits of autonomic management of Clouds.Comment: 8 pages, 6 figures, conference keynote pape
Integrated Green Cloud Computing Architecture
Arbitrary usage of cloud computing, either private or public, can lead to
uneconomical energy consumption in data processing, storage and communication.
Hence, green cloud computing solutions aim not only to save energy but also
reduce operational costs and carbon footprints on the environment. In this
paper, an Integrated Green Cloud Architecture (IGCA) is proposed that comprises
of a client-oriented Green Cloud Middleware to assist managers in better
overseeing and configuring their overall access to cloud services in the
greenest or most energy-efficient way. Decision making, whether to use local
machine processing, private or public clouds, is smartly handled by the
middleware using predefined system specifications such as service level
agreement (SLA), Quality of service (QoS), equipment specifications and job
description provided by IT department. Analytical model is used to show the
feasibility to achieve efficient energy consumption while choosing between
local, private and public Cloud service provider (CSP).Comment: 6 pages, International Conference on Advanced Computer Science
