Server Consolidation Through Virtualization with Quad-Core Intel® Xeon® Processors
Traditional server consolidation achieves cost reduction through consolidation of hardware and software but often compromises performance, availability and agility. Server consolidation using virtualization technology offers simplified architecture while reducing costs and enhancing agility and flexibility of an enterprise. This paper showcases the benefits of virtualization using Quad-Core Intel® Xeon® processors to consolidate servers and reduce total cost of ownership.
Server Consolidation & VirtualizationEnterprises are witnessing a server sprawl as low cost x86 boxes make their way into datacenters. Application provisioning on dedicated servers and over-provisioning hardware for peak loads have led to server proliferation and low utilization. Virtualization technology can play a significant role in server consolidation. It enables enterprises to achieve higher utilization and manage hardware resources better, thus reducing Total Cost of Ownership (TCO).
Virtualization Technologies
Hardware over-provisioning has led to high TCO and low ROI on IT infrastructure. Virtualization provides a solution to address these issues. It is a technique to transform hardware resources viz. processors, storage, I/O and networks on one or more machines into multiple execution environments, each of which can act as a complete system by itself. This is done by hardware or software partitioning, time sharing and simulation/emulation of target machine. Virtualization brings in benefits such as isolation, security, increased resource utilization and simplified management.
Xen & Server Consolidation
Enterprises are witnessing a server sprawl as low cost x86 boxes make its way into their datacenters. Application provisioning on dedicated servers and provisioning hardware for peak loads have led to abysmally low server utilization. Virtualization technology can play a significant role in logical server consolidation, enabling higher utilization and better management of hardware leading to lower TCO. Xen, based on para-virtualization, is an ideal solution for server consolidation.
Linux & High Performance Computing
Linux has come to represent the Open Source movement. The core of the Linux OS is the Linux kernel. Started as a college project in 1991, Linux is now a very powerful and feature-rich operating system. It supports a wide variety of hardware with excellent support for clustering and virtualization technologies. Further, the open source nature of the product has led to excellent security features. Linux thus is highly suitable for high performance computing and clustering solutions.
ESB - A bandwagon worth jumping on
Bijoy Majumdar, Terance Dias, Ujval Mysore
Most ESB critics say that the ESB is nothing but a glorified integration platform which has already existed for some time now in the form of EAI tools; and that most people are just jumping on this "bandwagon" without actually understanding that it has got nothing new to offer. In this paper we put forth our views on why an ESB is a preferred platform for integration of services for enterprises that are aiming to achieve Service Oriented Architecture and what makes it "Abandwagon worth jumping on".
Live URLs: Breathing life into URLs
This paper provides a novel approach to use URI fragment identifiers to enable HTTP clients to address and process content, independent of its original representation.
Designing an Enterprise Application Framework for Service-oriented Architecture
Service-Oriented Architecture (SOA) aims to achieve agile enterprises with flexible IT infrastructure that quickly adapts to changes in the dynamic business environment. Drawing on experience gained from designing the Infosys Radien Framework, this paper illustrates the building blocks required for designing and implementing applications using SOA concepts. Using a systematic requirements-driven approach, it guides application architects and developers in developing an enterprise application framework for SOA from the concept to design and implementation levels.

Experiences with Memory Access Issues in RTOS
Narendra Ramanna
Based on the architecture of the operating system as well as the nature of the software defect, memory access issues often encountered on Real-Timer Operating Systems [RTOS] may be either very simple or a cryptic puzzle. This article presents some of the memory access issues often noticed on "simpler" models of soft Real-Time Operating Systems.
