Term Paper Website Migration Project Due Week 10

Tony's Chips has recently been sold to a new independent company. The new company has hired you to manage a project that will move the old Website from an externally hosted solution to an internal one. The company's leadership is very concerned about redundancy for their site, insisting that a back-up site be available as a fail over in case the main site goes down. In addition, they want the site redesigned to allow customers to order products online. As part of your job, you must complete a 10-to-15-page paper that follows this project through the system development life cycle (SDLC).

This assignment will require you to do the following: · Discuss what it will take to build a Web architecture, move an existing Website with minimal downtime, and provide a disaster recovery solution to ensure the site is always available. · The Web architecture should describe and justify operating system choices (i.e., Linux, Apache, MYSQL, PHP, Windows, IIS, SQL, etc.). · Evaluate alternatives to the company self-hosting the site. · Build a Gantt chart using Microsoft Project or equivalent software, showing all tasks associated with implementing the Website. · The chart should include a minimum of five (5) tasks, each with three (3) sub-tasks. · Explain and justify the system architecture you have selected. · Illustrate the system architecture using Visio or equivalent software. · Create a use case that documents the event of a customer ordering a bag of chips from the new Website. · The use case should include a graphical representation using Visio or equivalent software and a text description of the events. · Discuss the support operations that the internally hosted Website will require after implementation. · Explain how you will evaluate the performance of the new site and the success of your project.

Paper For Above instruction

The migration of Tony's Chips website from an external hosting environment to an internal infrastructure represents a critical project that necessitates meticulous planning and execution. This paper explores the system development life cycle (SDLC) phases involved in designing, implementing, and maintaining the new website, emphasizing web architecture, disaster recovery, and system evaluation to ensure continuous availability and enhanced customer interaction through online ordering capabilities.

Planning and Analysis

The initial phase involves comprehensive analysis of the existing website architecture, identifying operational requirements, and understanding the technical limitations. An essential component is the evaluation of hosting options—self-hosting versus cloud services. While cloud solutions such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform offer scalability and redundancy, self-hosting grants greater control over data and security but requires significant investment in infrastructure, staffing, and maintenance.

The company's leadership demands high availability through redundancy and disaster recovery measures. These considerations shape the choice of system architecture, indicating the need for multiple servers, load balancing, and failover mechanisms. The goal is to minimize downtime, safeguard data, and ensure smooth customer experiences, especially during peak traffic or unexpected outages.

Designing Web Architecture

The proposed web architecture adopts a Linux-based environment utilizing the LAMP stack—Linux, Apache, MySQL, and PHP—due to its stability, security, and open-source advantages. Linux's cost-effectiveness and extensive community support make it ideal for small to medium enterprises. Apache serves as a robust web server capable of handling high traffic volumes, while MySQL manages database operations for online orders and customer data efficiently. PHP facilitates dynamic content generation and integrations necessary for online shopping functionalities.

Alternatively, a Windows-based environment employing IIS and SQL Server could be considered, particularly if the company already operates within a Windows ecosystem. However, the LAMP stack’s flexibility and lower total cost of ownership generally favor Linux-based solutions for startup and mid-sized businesses.

In terms of redundancy, deploying multiple web and database servers in a clustered setup with load balancing ensures the site remains accessible even if one server fails. Backup servers configured with automated synchronization provide disaster recovery support, allowing rapid switchover if primary systems experience issues.

Evaluating Hosting Alternatives

While self-hosting offers control, cloud hosting platforms provide elastic scalability, reduced infrastructure costs, and managed redundancy options. Cloud providers typically include integrated disaster recovery and backup services, simplifying implementation. For Tony's Chips, a hybrid approach could leverage cloud services for redundancy while maintaining critical operations internally, or opt entirely for cloud to minimize overhead.

Another alternative is colocation, where the company owns hardware but rents space within a data center, blending control with professional infrastructure management. The evaluation must consider factors like initial investment, ongoing operational costs, security, compliance, and scalability.

Project Scheduling: Gantt Chart

A detailed Gantt chart encapsulates key tasks such as requirements gathering, system design, hardware procurement, software development, testing, deployment, and training. Each task decomposes into sub-tasks—for example, under 'System Design,' sub-tasks include server configuration, database setup, and security protocols. The timeline ensures stakeholders track progress, manage dependencies, and allocate resources effectively.

System Architecture Justification

The chosen architecture emphasizes modularity, security, and scalability. Using Linux and open-source tools reduces costs and enhances customization potential. Clustering and load balancers ensure high availability, while automated backups safeguard data integrity. The architecture incorporates VPNs for secure remote management and SSL certificates for secure customer transactions, adhering to best practices in e-commerce security.

Visual Representation of Architecture

The system architecture is illustrated through a diagram crafted in Visio, depicting web servers, database servers, load balancers, backup nodes, and network security components. This visual aids understanding of the system's resilience and scalability features, aligning with design objectives.

Use Case: Customer Ordering Chips

The use case models a customer's interaction from browsing the website to completing a purchase. It begins with the customer logging in, selecting a product, adding it to the cart, proceeding to checkout, entering payment info, and receiving order confirmation. The diagram illustrates this sequence, showing interactions between the customer, web interface, application server, database, and payment gateway.

Operational Support and Performance Evaluation

Post-implementation, support involves routine maintenance, security patches, system monitoring, and customer service. Automated alerts and logging facilitate issue resolution. Performance metrics such as site uptime, page load times, transaction completion rates, and customer feedback serve as benchmarks. Regular reviews ensure the system adapts to evolving demands, and performance audits confirm the project's success in achieving availability, reliability, and customer satisfaction.

Conclusion

Transitioning Tony's Chips website to an internally hosted, resilient, and scalable platform enhances control, security, and customer service capabilities. A well-planned SDLC approach, combined with appropriate technology choices and vigilant operational support, ensures continuous online presence and improved business performance.
