Throughout the three decades of its presence on the IT market, ScienceSoft has witnessed the slow but steady shift from the on-premises to web-based software. Scalability is an essential characteristic of a successful application. If you plan to develop your business and expand the system in the future, and you need to take care of the scaling in advance. The application has a scalable web architecture that allows it to handle the growing number of clients and an increase in operating activity. The Project Guide lets users filter projects by a creator, industry, and project status.

Database server and business logic is physically close, which offers higher performance. It also depends on what stage of the development process we hit an impasse due to the hasty decisions taken during the initial design phases. So, before we even touch the code and get our hands dirty, we have to make the underlying architecture right. The architecture helps define a solution to meet all the technical and operational requirements, with the common goal of optimizing for performance and security. An event driven architecture may be based on either a pub/sub model or an event stream model.

In the case of the backend, you should choose a relevant platform in terms of static and dynamic nature for the domain. Choose the server and language that go perfectly with one another.

Over the last few years, the preferred platform to deliver content and services has been the web. Thus, companies of all shapes and sizes needed to be online and present for their prospects and regular clients.


The layer always sets definitions for the logic for the business operations as well as the rules. An architectural style can be used to define the principles behind the Web architecture such that they are visible to future architects. As discussed in Chapter 1, a style is a named set of constraints on architectural elements that induces the set of properties desired of the architecture. The first web application architecture step in my approach, therefore, is to identify the constraints placed within the early Web architecture that are responsible for its desirable properties. The Web is intended to be an Internet-scale distributed hypermedia system, which means considerably more than just geographical dispersion. The Internet is about interconnecting information networks across multiple organizational boundaries.

Despite the apparent advantages of this approach, with a substantial increase in the data volume, the tables become too cumbersome. Indexes are closely connected to the data retrieval in case it’s spread out among physical devices. They allow finding a small piece of information in a vast data set quickly even if it’s distributed among many physical devices. ✓ You can insert the cache on the requesting node to make the data retrieval almost immediate for your customers. The more nodes your app will have, the more caches there will be, as each node should have its cache. Caches are the most widespread solution, which won’t harm but enhance your platform. It enables service performance increase due to the nodes adding.

Event-driven architecture enables minimal coupling, which makes it a good option for modern, distributed application architectures. With an event-driven system, the capture, communication, processing, and persistence of events are the core structure of the solution. Updating or scaling a single aspect of a monolithic application has implications for the entire application and its underlying infrastructure. In earlier days, application deployment was a difficult process and could not be done during normal business hours. However, different deployment methods (such as blue-green and canary deployment) along with DevOps and CI/CD now allow deployment at any time without any application outages.

Php Vs Python: Which One To Choose For Web Development?

It facilitates low-level memory manipulation and developers can write distributed systems with more control over memory. Finally, AngularJS web application architecture serves both as a platform and a framework for HTML and TypeScript. This type of web architecture relies on Software Engineering Body of Knowledge building blocks called NgModules. Among its key benefits is lazy loading, which improves user experience and reduces code size. In essence, .NET web application architecture deals with cross-platform support, microservices, Docker containers, and side-by-side versioning.

The database server component stores, retrieves and provides the data. Nowadays, having an online presence also means being mobile as more and more web access originates with mobile devices. Mobile application architecture plays a key role in how developers approach client requirements to ensure there are consistency and availability across all platforms. As more complexity is added to applications, developers, in turn, become less specialized in covering multiple development skills.

They are also good enough for setting user interactions in a hassle-free manner. The primary goal is to always get the input data and the user’s request by sending them to the data service and showing the results. This understanding ensures meeting the business needs and the goals in a hassle-free manner. That said, in this article, you would be getting the answer to what is web application architecture? You will also get access to highlights on the web application architecture layers, components, models and its types alongside the best practices for giving you enhanced results. This type of architecture is based on a single logic, i.e., the user gets the entire HTML on request. All the other elements accordingly react to the full load of the page.

With proper load and performance testing, you’ll be able to find and eliminate the bottlenecks of your app and ensure its smooth growth. Testing aimed at identifying this point is called a ramp-up test. It helps to determine the reliability and scalability of a web application, as well as identify the system bottlenecks that undermine the effective operation of the entire system. Scalability can be assessed through the ratio of the increase in system performance to the rise in resources used. Also, scalability means the ability to add extra resources while keeping the structure of the central node intact. The website scalability definition is the ability of a system, network, or process to cope with the increase in workload when adding resources .

The primary goal is to ensure that all elements work together correctly. As you can see, there’s a wide range of best web application architecture platforms, and each one has a lot of peculiarities. We’ve covered only basics like components, layers, and types to explain web application architecture concepts. By applying to a professional software company, you can find out more details about web architecture, and receive a qualitative consultation to develop your own flawless product. Web development architecture advancement tends to have more voice queries, and we are not talking about interacting with smart home solutions like Siri, Google Home, or Alexa. In 2021, 48% of users will be applying voice solutions for making search requests. What’s more, by 2023, 40% of entire user interactions will be fulfilled by using AI and machine learning.

  • It comes after the architecture part when software engineers start the development process.
  • Server-side, also known as the backend, controls the business logic and responds to HTTP requests.
  • Besides, at least two servers, connected to the load balancer, process the user’s requests.
  • We are talking about components like middleware systems, user interfaces, web servers, database servers, load balancers, and databases.

It’s comprised of at least a centralized hub or control center to support multi-layer applications. Web Application Architecture is a framework that is comprised of the relationships and interactions between application components, such as middleware systems, user interfaces, and databases. The general concept of Web Application Architecture is in line with the concept of a browser user who triggers an application that is capable of running in multiple websites. Two more names for this layer are Domain Logic or Application Layer, which completes the processing of customers’ queries from the browser and directs the ways of access to this data. So directions by which the backend obtains the data and client queries are encoded in a business layer.

In fact, it should be efficient and straightforward to ensure smooth web app development and maintenance. It’s the truth that high-level architecture provides an easier extension and modification as well as testing, debugging, and comprehension. Single-Page applications or SPAs aim to facilitate programmers’ work. To make an action on a website, a user has no need to load completely new pages every time. Instead, they can interact with it receiving updated content to the current page. However blurred the line between frontend and backend development, web application works with them both.

It works by passing messages through a separate interface and works like an API. All these issues are addressed in the web application’s architecture. We’ll cover the basic concepts of any modern web application and explain how the architecture patterns may differ depending on the application you’re building. There are several things teams can do to ensure they are making the right choice.

This chapter presents the requirements of the World Wide Web architecture and the problems faced in designing and evaluating proposed improvements to its key communication protocols. It is essential to ensure your modern web app architecture can be scaled horizontally across several servers and regions to handle massive website traffic fluctuations.

Angularjs Web App Architecture

All this combined leads to flexibility and efficiency while developing reliable web applications. Mobile Application Architecture is comprised of these three building blocks just like described in the components of web app architecture. It is similar to MIcroservices in some aspects, however, the development entity – developer or development company does not own or manage the backend servers. This simple web application architecture diagram will help you to get easily acquainted with the process. As I said previously, the web application software architecture contains many components. But to build a perfect and robust web application, the critical part is to select the right web application architecture and its components. A properly planned and opted web application architecture minimizes many impromptu issues and bugs, saving a heck of development time and resources.

I think it’s better to configure a CI/CD platform with infra for tests and a few basic tests pretty close to the beginning of the project. Three main platform for CI/CD are Jenkins, Travis, and CircleCI. Jenkins has been there for over 10 years, while Travis and CircleCI are more modern. When the project is bigger with more people, it’s good to use some deployment tool like Ansible to manage the different steps of the process.
