What web application architecture is all about, can be simply described like how movies come to light. When you watch a movie, all you get to see is a complete scene of actors, actresses, soundtrack, and a location; and this is a watch for you as an audience, but you can barely realize the core roles that a director, a cameraman, and a movie staff are doing there. Also when it comes to mobile applications and web applications, there’s a behind the scene that’s full of delicate details and mysterious worlds to discover to know how that perfect scene of a web app came out to screens.
What is web application architecture?
Web application architecture defines the interactions between applications, middleware systems
and databases to ensure multiple applications can work together.
When a user types in a URL and taps “Go” the browser will find the Internet-facing computer the website lives on and requests that particular page.
Web applications are constructed following an architecture that specifies how components are linked.
What are the components of a web application architecture?
- Browser
- Web server
- Database server
How does a web application architecture work?
A user writes on his browser Roselladigital.com, the web server receives his ip address, data, and request,
and sends them to the server where the data of Roselladigital.com is located, in order to come back to the user with the page requested.
There are 3 models of web application:
- One web server - one database server.
- Multiple web servers - one database server.
- Multiple web servers - multiple database servers.
Types of Web Application Architecture
When developing an app, it’s always a good idea to stick to the most appropriate architecture based on the app’s logic, functionality,
and so on. The correct architecture defines the objective of the entire product.
There are four kinds of web applications, as listed below:
Single Page Application Architecture
SPA (Single Page Applications) seeks to overcome the classic difficulty of constructing smooth apps,
in order to provide an easy-to-use, intuitive user experience. These difficulties are overcome by SPA.
A SPAs loads a single web page and updates the data on that page with dynamically generated content rather than loading a new page.
Instead of loading a new page, SPAs load a single page and refresh the data on that page with dynamically updated content.
The front end receives the same logic as the back end.
JavaScript frameworks are used to develop SPAs on the client side using client-side JavaScript frameworks.
We want to build a technological tool that may function as an automated directory connecting event organisers, property owners, and food entrepreneurs.
Food Truck Spaces was created using AngularJS and ASP.Net API.
The web application automatically books, advertises, and online handles transactions using it.
Microservice Architecture
Monolithic architectures are now outcompeted by microservice architectures, which are built around a multitude of services that can function asynchronously to solve complicated problems.
Because APIs are used to communicate between services, they are loosely associated.
Deploying web apps has been made simple because of the lack of coupled parts in microservices.
Microservices have eliminated the difficulty of deploying service components in a monolithic fashion.
Microservices have prevented the necessity for numerous service components to be deployed in addition to eliminating the monolithic app deployment difficulty.
Amazon, Netflix, SoundCloud, Comcast, and eBay are a few of the country’s most renowned technology firms that use microservices.
Serverless Architecture
Cloud service providers such as Amazon and Microsoft manage the servers that are used by serverless architectures, so no manual intervention is required on the server.
No matter how complex your code is, cloud service providers can handle everything for you— you don’t need to deploy them manually on your server. Serverless architecture is a design pattern in which applications are built and run without any human intervention on servers managed by third-party cloud service providers like Amazon and Microsoft.
It allows you to focus on the quality of the product and the difficulty of making them highly scalable and reliable.
Backend-As-A-Service (BaaS) and Function-As-A-Service (FaaS) are the two types.
Developers who use BaaS to eliminate the back-end operations can focus on building the front-end aspects of their applications without worrying about operating the back-end.
Amazon Amplify, for example, is a popular BaaS product.
FaaS, on the other hand, is an event-driven model that allows developers to concentrate on coding and event triggers.
The remaining work will be handled by FaaS service providers such as Amazon Lambda and Microsoft Azure.
To develop an accessible and efficient web app, we collaborated with the FIH.
We used headless CMS, React, and integrated APIs to support serverless features.
Amazon EC2 was used to handle the enormous traffic, Amazon S3 to store videos, and Amazon CloudFront as a Content Delivery Network (CDN). Experts as well as Amazon AWS used Amazon EC2 to handle the huge traffic, Amazon S3 to store videos and Amazon CloudFront as a Content Delivery Network (CDN).
Progressive Web Applications
In 2015, Google created Progressive Web Apps (PWAs). To develop apps that offer rich and native functionality with enhanced capabilities, reliability, and ease of installation, PWAs were created.
A PWA is capable of functioning on any browser and on any device. It may be adjusted to run on a tablet and a desktop as well as on a tablet.
URL instead of app stores is used to discover and share these apps. These apps can be quickly added to a device’s home screen in addition to being installed quickly. Poor internet connection and offline mode are both advantages.
Several popular companies, such as Uber, Aliexpress, Alibaba, Pinterest, and Starbucks, manufacture their products by creating PWA websites.
Best practices for good web application architecture
You may have a working app, but it also needs to have good web architecture.
Here are several attributes necessary for good web application architecture:
- Solves problems consistently and uniformly
- Is as simple as possible
- Supports the latest standards include A/B testing and analytics
- Offers fast response times
- Utilizes security standards to reduce the chance of malicious penetrations
- Does not crash
- Heals itself
- Does not have a single point of failure
- Scales out easily
- Allows for easy creation of known data
- Errors logged in a user-friendly way
- Automated deployments
