How To Choose The Best Architecture For Your Web Application

There is an expanding set of tools building mashups from WOA resources. These tools Kanban (development) are beneficial to IT developers to create interoperability and integration.

Instead of completely reloading a web page, in response to the user’s request, only a certain area of ​​this page is reloaded, thus, it saves resources for each web app layer. This layer is responsible for receiving input data, processing them, then displaying the results that the server provided in the client browser. It includes all UI elements, as well as potential interactions that can occur between the user and the web page. Website development architecture is the result of the first phase of your product development. The documents that describe such an architecture detail things like the high-level components of your system, as well as the connections between them.

We recommend that you always keep your business objectives (including long-term goals) and product requirements in mind. There are several popular web application architecture patterns, and below we have described them for you. Understanding the logic of layers also enables you to more precisely estimate your web application development budget. In the next paragraph, we’ll describe the essence of the different layers and components of the web app architecture.

They provide offline access, push notifications, and a chance for installing an application to your home screen. Serverless architecture has no infrastructure or correlation associated tasks. In this framework, developers can work on the third-party infrastructure rather than backend server handling, hence, making it simple for developers to implement the web app. This layer sends data processed by the Business Logic Layer to the Presentation Layer. It separates the business logic from the client-side, assuring data security. User Interface components are associated with the configurations, display, and settings in the app. UI or UX is the major part of this component rather than what it will function after web app development architecture.


Hence, any server processes requests in the same manner, and the load balancer distributes tasks among them so they will not be overcharged. The service layer is another abstraction between Presentation and Business Logic.

The requestor utilizes an existing web service by opening a network connection and sending an XML request. The response travels across the internet, back to Alice’s computer. An API is a collection of clearly defined methods of communication between different software components. Eventually, a middleware function will be called that ends the request-response Setup CI infra to run DevTools cycle by sending an HTTP response back to the client. Web application architecture is fundamental to every web-based solution. Hence, its accomplishment highly relies on how properly it is studied and designed. These aspects are essential parts of the architecture development that provides an understanding of what it must be like.

Performance, memory, storage, app tiers and computing power are the necessary components of the server’s physical capacity. The web server architecture structure covers those points to complete the user’s requests to the full extension. The tasks of the database server are to arrange and store consistent information inside the app. In addition, the web application can also help the application server to stream any other data.


Consider these attributes of secure web application architecture to improve your web application security against common attacks and meet business needs. Single-page applications are becoming increasingly popular as they exhibit fewer page load interruptions, and are more cost-effective and quick to develop.

Therefore, when it comes to coding phases, the front-end and back-end developers can work to that spec. This, hopefully, sheds some light on the backstage of building modern websites. In this article, DevOps we dipped our toes into the complicated subject of software engineering. If this wasn’t enough for you, feel free to roam around our blog a bit more and specifically explore the following articles.

web architecture

This is a type of JavaScript application that can run both on the client-side and the server-side. First, the client loads an HTML, where the JavaScript app is uploaded to the browser, then the app starts running like an SPA.

A second option for viewing the web service architecture is to examine the emerging web service protocol stack. The stack is still evolving, but currently has four main layers. Let’s make all of this a bit more concrete, by following an example of the main steps that happen when a client makes a request to the server.

Web Application Architecture

SPA allows the user to continue interaction with the page while new elements are updated, thus you receive the fast interaction with the content reloading at the same time. The design can also be a wonderful tool for the partial page adjustment.

This layer is responsible for centralizing services into a common registry and providing easy publish/find functionality. Currently, service discovery is handled via Universal Description, Discovery, and Integration . Many requests sent to the server might require a database query. A client might request information that is stored in the database, or a client might submit data with their request to be added to the database. In this context, middleware is any code that executes between the server receiving a request and sending a response.

The walk through below should make it more approachable before we dive into the details of each component.

  • Many requests sent to the server might require a database query.
  • Instead, they can interact with it receiving updated content to the current page.
  • An index makes the trade-offs of increased storage overhead and slower writes for the benefit of faster reads.
  • So, in such a failure, all the requests will automatically go to the new server, without affecting the web app’s functioning.
  • The load balancing will be a good idea as the loads increase is due the generation of HTML and it might affect the scalability.

If worked well, both server and client sides can create web application architecture. Progressive web apps can be described as SPAs that introduce additional features, such as increased performance speed, push notifications, offline functionality, and home-screen installation. As you may have noticed, most of these features aim at improving web apps’ usability on mobile devices, and that’s exactly why we at ScienceSoft believe that PWAs are here to stay. In this type, the web page construction logic is replaced by web services, and each page on the client has separate entities called widgets. By sending AJAX queries to web services, widgets can receive chunks of data in HTML or JSON and display them without reloading the entire page. This is the simplest and the riskiest model, where a single database is a part of the web app’s only server. At ScienceSoft, we don’t usually suggest using this model unless your web app is a test project or private practice.

It is the topmost tier and can be accessed by the end-user in the form of a desktop application, graphical user interface , or simply by running on a web browser. The Web Presentation tiers are mostly developed by using HMTL, CSS, and Javascript while desktop applications could be written in multitudes of languages which depends on the platform. The main types of presentation tiers are in the following forms. This is managed, organized, and processed through various means and structures.

Among the other drawbacks are the long time needed for the first load, poor routing and limited support of outdated browsers. Being a rather costly web architecture type, SPA is a fit for creating responsive UI for B2C users. In web development, you always want to scale horizontally because, to keep it simple, stuff breaks. Having more than one server allows you to plan for outages so that your application continues running. Lastly, you may reach a scale where it’s not possible to vertically scale any more. There is no computer in the world big enough to do all your app’s computations.

So in this case the inverted index would map to a location , and then B may contain an index with all the words, locations and number of occurrences in each part. Just as to a traditional relational data store, you can also apply this concept to larger data sets. The trick with indexes is you must carefully consider how users will access your data. In the case of data sets that are many TBs in size, but with very small payloads (e.g., 1 KB), indexes are a necessity for optimizing data access. Finding a small payload in such a large data set can be a real challenge since you can’t possibly iterate over that much data in any reasonable time. Furthermore, it is very likely that such a large data set is spread over several (or many!) physical devices—this means you need some way to find the correct physical location of the desired data. Another key part of service redundancy is creating a shared-nothing architecture.
