Web Application Architecture and Deployment

Deploy all components on a single server in a single-tier web architecture. The database, business logic, and front end share the same hardware and connect via an IP address.

Explore the two-tier web application architecture by distributing front end, business logic, and database across two machines via tcp/ip to balance load, boost security, and improve performance.

Explore three-tier web architecture, separating database, middleware, and front-end layers across physical or virtual servers, connected via LAN and IP networking for scalable deployment.

Set up database server components on dedicated hardware with an operating system and relational database management system, creating tables, views, and procedures, while planning separation from app logic and licensing.

Explore middleware server components and software requirements that enable the application server to connect front-end interfaces with the database within a three-tier architecture.

Explore front-end server components in a three-tier architecture, detailing a single server, required operating system, frameworks and libraries, and the application server that renders and serves the client interface.

Explore how virtual servers run multiple operating systems on a single hardware using VMware, sharing memory and resources, to host database, middleware, and front-end in a three-tier web architecture.

Learners explore how programming converts input data into output using algorithms and flowcharts, then translate them into Python code with name and salary and a 30 percent tax calculation.

Explore developing across the three web app tiers: database with sql variants, server-side middleware, and front-end client-side languages, and learn how to integrate them for full-stack development.

Design a three-layer process to validate account information: a front end login form, a server side check against the database, and coordinated collaboration among front end, back end, and database teams.

Expose a local network to the internet by obtaining a static internet IP, configuring the router to forward requests to the front-end server, and using a domain name for access.

Explore entity relationship diagrams (erd) to model a bank database with customers, accounts, and transactions, using primary and foreign keys to define one-to-many relationships.

Explore the modern front-end architecture with JavaScript frameworks on an application server, detailing the model, view, and controller and how data moves from database to the browser via JSON.

Explore how Angular's three-layer architecture—data model, logic (controller), and presentation (view)—drives component interaction via injectable services, two-way data binding, and API communication.

Explore Node.js, an open-source, cross-platform server-side runtime for JavaScript, enabling an event-driven, non-blocking model that handles more requests with the same resources for real-time applications, payment processing, and content management.

Understand node.js internal architecture and non-blocking I/O, using the event loop, call stack, and callbacks to handle http requests and database calls without blocking.

Explore Node.js behavior with remote database calls and non-blocking performance, comparing remote and local queries, using callbacks to fetch categories and top 20 orders.

Create a map server with node.js and express by initializing a package, defining port 3700, and routing '/map' to render a map, then run the server with node app.js.

Install Python 3 and VS Code; set up a Django project with models, views, and templates; test APIs with Postman; manage databases using a database browser.

Build a web application by creating templates, defining views, and configuring routing; render HTML responses, run a local application server, and test interactive forms in the browser.

Create a templates folder, register it in settings, and implement a view function that renders the template, establishing a responsive navigation with linked stylesheet and script assets.

Create a database model, migrate it, retrieve data, and render it in a template using a data dictionary key, with sample records added via the shell.

Explore working with a database model by manipulating objects in a module class within a virtual environment, printing data, iterating over records, and displaying names, telephones, and generated IDs.

learn to design reusable templates using parent and child templates, with extends and block content, to add a persistent menu and scalable layout across web pages.

Access dictionary KeyData from both the base document and the child test by moving data outside the block content in html templates.

Create and activate a Python virtual environment for a Django web app, install the Django Rest framework, and run the server on 172.0.0.1:8000.
