As Part Of Your Job You Must Complete a 10 To 15 Page Paper That Foll

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 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.). You should evaluate alternatives to the company self-hosting the site. Additionally, you are to 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. Furthermore, you need to explain and justify the system architecture you have selected and illustrate it using Visio or equivalent software.

Develop 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 and explain how you will evaluate the performance of the new site and the success of your project.

Paper For Above instruction

The process of developing a comprehensive web system involves several stages, from planning and architecture design to implementation, testing, and maintenance. This paper explores these stages through the lens of a hypothetical project to upgrade and migrate a company’s website, highlighting critical considerations for web architecture, system design, and operational support, all aligned with the system development life cycle (SDLC).

Web Architecture Design and Operating System Choices

The foundation of a robust website is its architecture, which encompasses hardware, software, network configurations, and security measures. Choosing the right operating system (OS) is fundamental to ensuring performance, stability, and scalability. For this project, two primary options are considered: Linux-based systems using Apache, MySQL, and PHP (LAMP stack), and Windows-based systems utilizing IIS, SQL Server, and .NET framework. Each option presents trade-offs in terms of cost, flexibility, security, and compatibility.

The LAMP stack is renowned for its cost-effectiveness, open-source nature, and strong community support. Linux servers, in particular, are known for their stability and security, which are critical for minimizing downtime and potential cyber threats. Apache as a web server offers extensive customization and reliable performance, while MySQL provides an open-source, scalable database solution. PHP complements these components with wide adoption and ease of integration.

Conversely, Windows Server environments with IIS and SQL Server may appeal to organizations with existing investments in Microsoft technologies or requiring specific features such as Active Directory integration and enterprise-level support. While this option may incur higher licensing costs, the seamless compatibility within Microsoft ecosystems can facilitate easier management and integration.

After evaluating these factors, the justification for selecting a Linux-based architecture (LAMP) hinges on cost efficiency, security features, and community support, making it ideal for a scalable, reliable web environment for the company.

Alternatives to Self-hosting

Hosting options significantly influence the website's accessibility, scalability, and security. Alternatives to self-hosting include cloud hosting providers such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. These services offer Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) options, providing flexible, scalable, and cost-efficient solutions.

Using cloud hosting can reduce capital expenditures related to hardware procurement and maintenance while enabling rapid deployment and scalability during traffic surges. Cloud providers also offer integrated security, backup, and disaster recovery services, which are essential for maintaining high availability.

However, moving to cloud hosting introduces considerations regarding data sovereignty, compliance, and potential vendor lock-in. A hybrid approach combining on-premises hosting with cloud services can offer optimal flexibility, balancing performance control with cloud scalability and resilience.

Gantt Chart Development

Creating an effective Gantt chart involves outlining the key tasks and sub-tasks associated with website deployment. For this project, five primary tasks are identified:

  1. Planning and Requirements Gathering
    • Stakeholder analysis
    • Scope definition
    • Resource allocation
  2. System Architecture Design
    • Design of web and database servers
    • Security architecture planning
    • Network infrastructure design
  3. Development and Migration
    • Code development or modification
    • Data migration planning
    • Testing and quality assurance
  4. Implementation and Deployment
    • Setup of hosting environment
    • Deployment of website and database
    • Minimize downtime during migration
  5. Post-Deployment Support and Maintenance
    • Performance monitoring
    • Backup and disaster recovery testing
    • User training and documentation

Each task comprises three detailed sub-tasks, which can be scheduled and managed using Microsoft Project or similar software to ensure timely completion and resource coordination.

System Architecture Justification and Illustration

The chosen system architecture leverages a modern, scalable, and secure web environment built on a Linux-based stack. The architecture includes load-balanced web servers running Apache, connected to backend MySQL databases, all protected by firewall and intrusion detection systems. This design ensures high availability, load distribution, and efficient data management, aligning with best practices in web development and deployment.

Diagrammatically, the architecture depicts multiple web servers behind a load balancer, connected to a centralized database cluster, with security layers including firewalls, SSL/TLS encryption, and intrusion detection. This setup provides redundancy and fault tolerance, critical for disaster recovery and minimal downtime scenarios.

Use Case Development

The primary use case involves a customer ordering a bag of chips from the website. The steps include the customer accessing the site, browsing the products, adding a bag of chips to the shopping cart, proceeding to checkout, entering payment and shipping details, and confirming the order. The process is captured visually using Visio, illustrating actors, system interactions, and data flow.

The use case diagram showcases the customer as the primary actor initiating the purchase, with interactions involving web servers, databases, and payment gateways. Textual description details each step, ensuring clarity for developers and stakeholders.

Post-Implementation Support and Performance Evaluation

Post-deployment, support operations include regular system monitoring using tools like Nagios or Zabbix, routine backups, security updates, and user support. Continuous performance evaluation involves analyzing website traffic, server response times, error rates, and user feedback. Success metrics include reduced downtime, improved load times, high user satisfaction, and achievement of initial project goals.

Applying analytic tools and conducting periodic reviews ensure the website remains aligned with organizational needs and technological advances, fostering ongoing improvements and resilience.

Conclusion

The development and deployment of a web architecture that balances performance, security, cost-efficiency, and scalability require meticulous planning across the SDLC. Choosing an appropriate operating system, evaluating hosting alternatives, designing scalable architecture, and establishing effective support mechanisms are vital for success. Through comprehensive planning, visualization, and ongoing evaluation, the organization can ensure a resilient, efficient, and user-friendly web presence that supports business growth and operational excellence.
