Executive Summary

This document describes the engineering, furnishing, and installation (EFI) technical aspects of the information systems infrastructure for an e-commerce company. The system is designed to support the company's business processes, including online ordering, payment processing, inventory management, and customer relationship management (CRM).

Full Answer Section

      System Overview The system infrastructure is based on a cloud-based platform, which provides scalability and flexibility. The core components of the system include:

• Web servers: The web servers host the company's website and provide the necessary computing resources to handle customer requests.
• Application servers: The application servers host the company's e-commerce application, which provides the functionality for online ordering, payment processing, and inventory management.
• Database servers: The database servers store the company's data, including customer information, product information, and order information.
• Content delivery networks (CDNs): The CDNs deliver the company's static content, such as images and CSS files, to customers around the world with low latency and high availability.

System Requirements The following are the hardware and software requirements for the system: Hardware:

• Web servers: 2 x 16-core CPUs, 32GB RAM, 1 TB storage
• Application servers: 2 x 8-core CPUs, 16GB RAM, 500GB storage
• Database servers: 2 x 4-core CPUs, 8GB RAM, 2 TB storage
• CDNs: 2 x 100 GB capacity

Software:

• Web servers: Nginx or Apache
• Application servers: Java or Node.js
• Database servers: MySQL or PostgreSQL
• CDN: Cloudflare or Amazon CloudFront

System Architecture The system architecture is shown in the following diagram: [Diagram of system architecture] System Engineering The system will be engineered using a DevOps approach. DevOps is a set of practices that combines software development and IT operations to shorten the systems development life cycle and provide continuous delivery of high-quality software. The following steps will be involved in the engineering of the system:

1. Requirements gathering and analysis: The first step is to gather and analyze the system requirements. This includes understanding the company's business processes, identifying the users of the system, and defining the system's functional and non-functional requirements.
2. System design: Once the requirements have been gathered and analyzed, the system will be designed. This includes defining the system architecture, selecting the hardware and software components, and designing the system's databases.
3. System development: The next step is to develop the system. This includes developing the e-commerce application, creating the database schema, and configuring the web servers and application servers.
4. System testing: Once the system has been developed, it will be tested to ensure that it meets the requirements and is free of defects.
5. System deployment: Once the system has been tested and approved, it will be deployed to production. This includes configuring the production environment, migrating the data from the development environment to the production environment, and testing the system in production.

System Furnishing The following equipment will be required for the system:

• Web servers: 2 x Dell PowerEdge R640 servers
• Application servers: 2 x Dell PowerEdge R440 servers
• Database servers: 2 x Dell PowerEdge R340 servers
• CDNs: Cloudflare or Amazon CloudFront

System Installation The system will be installed by a qualified systems integrator. The systems integrator will follow the system implementation plan to install and configure the system components. Post-Installation Support The systems integrator will provide post-installation support for the system. This includes monitoring the system's performance, providing technical support to the company's IT staff, and performing system updates and maintenance.
