Modern WAN architectures require additional network capabilities to support current higher bandwidth
and mission-critical applications. Requirements for deploying voice over IP (VoIP) and video
conferencing include high availability, IP multicast, and quality of service (QoS). Today, most
enterprises rely on private WAN connections such as Frame Relay, ATM, or leased-line services to
connect their businesses.
Everybody’s talking about cloud services today. It’s one of the hot new buzzwords, but
most of the conversation is about how to develop custom applications in the cloud.
While that is a really important topic, it ignores another very useful attribute of a distributed
cloud: as a great place to build and host an IT infrastructure.
The dearth of discussion about this overlooked facet of cloud computing is the reason
I wrote this book.
If you're involved in planning IT infrastructure as a network or system architect, system administrator, or developer, this book will help you adapt your skills to work with these highly scalable, highly redundant infrastructure services.
While analysts hotly debate the advantages and risks of cloud computing, IT staff and programmers are left to determine whether and how to put their applications into these virtualized services.
The rapid development of information technology and communications has created an opportunity to improve the efficiency of road traffic by using Intelligent Transportation System (ITS). The combination between transport participants, vehicles and road traffic infrastructure through using roadside equipments and traffic control centers takes a part in improving the efficiency of the transportation system and quality of transportation services.
In Vietnam, project cycle management (PCM) of road investment projects consists of investment preparation, implementation, construction, and operation processes. The postevaluation of projects during operation has not yet been considered through PCM in a systematic and effective manner. This paper discussed project management issues of road infrastructure projects in Vietnam. Then the paper introduced the post-evaluation process for integrating into Vietnam’s PCM using the PCM methodology developed by Foundation for Advanced Studies on International Development (FASID).
This report from the National Committee on
Vital and Health Statistics (NCVHS) outlines a
vision and a process for mobilizing the human,
institutional, and technological factors needed
to support health decisionmaking through a
National Health Information Infrastructure
(NHII). NCVHS, a public advisory committee,
is statutorily authorized to advise the Secretary
of Health and Human Services (HHS) on
national health information policy. It reports
annually to Congress on progress toward
privacy protection and administrative
The data center is home to the computational power, storage, and applications necessary to support an enterprise business. The data center infrastructure is central to the IT architecture, from which all content is sourced or passes through. Proper planning of the data center infrastructure design is critical, and
performance, resiliency, and scalability need to be carefully considered.
Service Oriented Architecture is an
Application Architecture that is designed to
achieve loose coupling among interacting
software applications. SOA provides greater
flexibility in developing, integrating, and
managing Enterprise Applications.Grid research, rooted in distributed and high performance computing, started in midto- late 1990s when scientists around the world acknowledged the need to establish an infrastructure to support their collaborative research on compute and data...
The world has come a long way since Duke first started tumbling in early versions of
Netscape Navigator. Java has outgrown its humble origins as a cool way of providing
interactivity on Web pages and has found a new role as a major, server-side development
platform. The actual Java language has changed little in the intervening years, but an
enterprise-quality infrastructure has risen up around it.
Despite the great technological advancement experienced in recent years,
Programmable Logic Controllers (PLC) are still used in many applications from the real
world and still play a central role in infrastructure of industrial automation. PLC operate in
the factory-floor level and are responsible typically for implementing logical control,
regulatory control strategies, such as PID and fuzzy-based algorithms, and safety logics.
Usually PLC are interconnected with the supervision level through communication
network, such as Ethernet networks, in order to work in an integrated form....

The data center is the repository for applications and data critical to the modern enterprise. The
enterprise demands on the data center are increasing, requiring the capacity and flexibility to address a
fluid business environment whilst reducing operational costs. Data center expenses such as power,
cooling, and space have become more of a concern as the data center grows to address business
Blade servers are the latest server platforms that attempt to address these business drivers.
There was a time when each of your employees had no more than a
computer. The user-to-device ratio was one-to-one. But look around
you today. What do you see? Wireless devices, IP telephones, IP security
cameras, IP building controls, and more—all converged on the same
network. The number of applications supported by a single network
has grown tenfold. According to premier research provider IDC, nearly
three-quarters of global organizations are expected to migrate to a fully
converged enterprise by the end of 2008.+...
This book is targeted primarily at Windows server administrators who are responsible
for hands-on deployment and day-to-day management of Windows-based
servers for large organizations. Windows server administrators manage file and
print servers, network infrastructure servers, Web servers, and IT application
Before looking at the steps necessary to build the preceding application, I should cover what
the term .NET means and what it offers to a software developer. .NET is an infrastructure that
provides two major benefits: productivity and security. Using .NET, a developer can write code
for many modern problem domains faster, and during coding, the developer faces fewer pitfalls
that could end up in security vulnerabilities. Furthermore, .NET code can be
implemented so that it can be executed with restricted access to APIs.
This guide describes the Cisco WAN and application optimization solution. The guide provides detailed
technical information about the design and implementation of the solution.
The WAN and application optimization solution combines Cisco products and technologies to deliver
solutions to specific WAN and application optimization challenges. This guide helps its readers understand
these challenges, and design and implement networking infrastructures to meet the challenges.
Regardless of their basic purpose, virtually all e-commerce sites rest on the same network structures,
communication protocols, and Web standards. This infrastructure has been under development for over 30
years. This appendix briefly reviews the structures, protocols and standards underlying the millions of sites
used to sell to, service, and chat with both customers and business partners. It also looks at the infrastructure
of some newer network applications, including streaming media and peer-to-peer (P2P)....
Your data center is the most critical resource within your organization. As you know, it provides the means for all storage, management and dissemination of data, applications and communications for your business. When employees and customers are unable to access the servers, storage systems and networking devices that reside in the data center, your entire organization can shut down. Millions of dollars can be lost in a matter of minutes for businesses like banks, airlines, shipping facilities and online brokerages.
