1. Introduction

Web application development and deployment are more complex than creating code and putting it on remote servers due to the ever-changing nature of the software business. Diverse teams (such as developers, designers, managers, system administrators, etc.) using various tools and technologies must work together in today's software development lifecycle to efficiently meet complex application requirements.

Without careful management, such a partnership may quickly spiral out of control in terms of complexity and expense. An overview of Web Applications and their supporting infrastructures is provided here. A demonstration is implemented on Amazon Web Services to illustrate the usefulness of the information presented.

Web applications can be deployed and served using various infrastructure types. There are benefits and drawbacks to each approach, as well as potential applications for each.

This course is split into two parts: a theoretical section that lists and describes various ideas associated with web applications and infrastructure and a functional unit to help you apply and make sense of that material.

2. Web Apps vs. Websites: What Gives and Why

Websites are related resources such as text files, photos, video files, and scripting languages like HTML, CSS, and Java. The only thing users can do on websites is retrieve the information they contain. Also, since most websites are stateless, responses to queries from various users are always the same. Websites may include but are not limited to those of businesses, individuals, news organizations, etc.

However, web applications go beyond simple web pages by providing many features. Web applications are everywhere nowadays; think about Google, Facebook, Instagram, or even online gaming or shopping. Users can engage with these programs in various ways, including making profiles, playing games, making purchases, etc.

The architecture of a web application can become significantly more complicated than a website because of the need to support such advanced features. There are three levels to each software that runs on the web. The application's design can include more than the three layers covered in this guide.

Presentation Layer: The primary functions of client apps are information display and user input. Numerous frontend development frameworks exist: You can use JS frameworks like Angular, React, Vue, etc.

2. Application (Business Logic) Layer: This layer is part of the application's server side. It takes in user requests, processes them, and then communicates with databases to update information. NodeJS, Python, PHP, Java, etc., can be used to build such programs.

3. Database Layer: This is where all data resides and is stored.

Elements of a Web-Based Application

To recap, a website is an application built solely from hypertext markup language (HTML), cascading style sheets (CSS), and Javascript. On the other hand, web applications are more complicated and comprise several parts. There are three main parts to a web app: Frontend Application, backend application, and database.

The parts mentioned above are fundamental for developing web apps. However, the latter may need other components to perform more sophisticated functions.

1. Caching is performed with an in-memory database.
2. The second usage for the message bus is asynchronous messaging.
3. Caching and serving static content is a crucial function of a Content Delivery Network.
4. Businesses employ a Workflow Management Platform to keep things running smoothly.

The underlying web application will expand in size and complexity in tandem with the application's use case. As a result, it's essential to structure and architect the application properly.  One can join Best AWS Training Institute in Chandigarh, to get expert in web based application on AWS.

Physical Server

Hardware resources in such architecture would need to be procured, configured, and managed at a physical location (like a data center). Applications can be deployed after they have been set up and an OS has been installed. Proper configuration and management must be guaranteed throughout the servers' and apps' lifetimes.

Advantages

1. Ownership: Complete authority over both the server and the application.

2. Speed: All available server resources are open to the programs running on the server.

Disadvantages

High Capital Expenditure and Operating Expenditure: Implementing the necessary infrastructure components may call for a significant initial expenditure, followed by another one for continuing to operate and maintain the resources.

Administrative costs: always being there to maintain and oversee things.

Inability to scale: adjusting the computing resources is complex, time-consuming, and requires manual labor.

Mishandling of Resources: Waste of resources because of the inability to expand capacity.

Inadequate application isolation: All applications on the same physical host share the host's resources.

Deterioration of performance: - Hardware component failure causes gradual performance degradation over time.

Virtual machines

Isolating the application components on specific environments and resources is a recommended practice when delivering web applications.

In this example, we'll assume that our application consists of the following parts:

• A MySQL database
• A NodeJS backend API service
• A Dotnet backend consumer service
• A ReactJS frontend application

These features typically require adequate server resources and a correctly installed and configured environment. Physical server deployment and management of such an application become onerous at scale.

Virtual Machines are the equivalent of the actual servers but in digital form. The ability to create and administer several Virtual Machines on a single Physical Server is made possible by hypervisors like Oracle VirtualBox, Microsoft Hyper-v, and VMware.

Virtual machines (VMs) of varying flavors can be constructed and set up on a single physical host. In a virtual environment, each machine has its own set of resources independent of others.

FAQ:-

Is AWS app development possible?

The AWS Course in Chandigarh Sector 34 Amplify suite of frontend web and mobile development tools and services makes creating apps with cloud capabilities on AWS simpler. Amazon Web Services (AWS) offers a comprehensive app creation, distribution, testing, and management platform.

Can I use AWS's free deployment service?

The AWS Free Tier allows users to experiment with AWS Training in Chandigarh Sector 34 services at no cost, subject to certain limits determined by the individual services. A 12-month Free Tier, an Always Free deal, and shorter-term trials comprise the Free Tier's three types of services.
