Lesson 1

Introduction to Site Infrastructure and Software

Now that you have planned your site, you have entered a crucial phase. You are now ready to pick specific tools and products to create the site.
This course provides a "vendor-neutral" approach to the concept of e-commerce. In addition to vendor-neutral content and concepts, you will also be exposed to various e-commerce vendor applications.
By the end of this module, you will know how to:
  1. Describe the elements of a Web server
  2. Select Web server software
  3. Assess Web site development software
  4. Assess support and database software requirements
  5. Configure hardware and software for security
  6. Assess the tasks required to integrate with legacy systems
  7. Assess outsourcing options
In the next lesson, Web servers will be discussed.
Successful design, implementation, and utilization of Internet-based systems require a thorough knowledge of several technologies, theories, and supporting disciplines. Internet and web technologies researchers and practitioners have had to consult many resources to find answers. Some of these sources concentrate on technologies and infrastructures, some on social and legal issues, and some on applications of internet-based systems. This module provides some of the relevant information in a comprehensive manner with a lively format. Each module incorporates core Internet topics, practical applications, and coverage of the emerging issues in the internet and web technologies field.

Infastructure Explained

Infrastructure is the foundation or framework that supports a system or organization. In computing, infrastructure is composed of physical and virtual resources that support the flow, storage, processing and analysis of data. Infrastructure
  1. may be centralized within a data center, or
  2. it may be decentralized and spread across several data centers that are either controlled by the organization or by a third party, such as a colocation facility or cloud provider.

In a data center, infrastructure includes the 1) power, 2) cooling and 3) building elements necessary to support hardware. On the internet, infrastructure also includes transmission media, such as cables, satellites, antennas, routers, aggregators, repeaters and other network components that control transmission paths. Cloud computing provides a flexible IT infrastructure in which resources can be added and removed as workloads change. (IaaS) Infrastructure as a Service model uses a third-party provider to host hardware, software, servers, storage and other infrastructure components on behalf of its users.
The way IT infrastructures are created is continually changing. Heutzutage, some vendors provide pre-engineered blocks of compute, storage and network equipment that optimize the IT hardware and virtualization platform into a single system that can be easily interconnected to other systems. This modular approach is called converged infrastructure.
