Types of Web Applications

• Talking in terms of computing, a web application
  or a web app can be termed as a clientserver
  computer program where the client, including the
  user interface and client-side logic, runs in a
  web browser. Some of the most common types of web
  applications are webmail, online retail sales,
  online banking, and online auctions among many
  others.
• One cannot clearly differentiate between a
  dynamic web page of any kind and a web
  application. Those websites which are referred
  to as web applications are the ones which have
  similar functionality to a desktop software
  application, or to a mobile app.

How did web applications originate?

• In earliest versions of computing models where
  clientserver model was used, you would see that
  the processing load for the application was
  shared between code on the server and code
  installed on each client locally.
• Earlier applications had their own pre-compiled
  client program that used to serve as its user
  interface and had to be separately installed on
  each users personal computer.
• If one upgraded the server-side code of the
  application, they would also typically require an
  upgrade to the client-side code installed on each
  user workstation. This would in turn add to the
  support cost and decrease productivity as well.

Components of web applications

• Any web application, big or small, contains these
  major components
• View Layer- When you consider an MVC
  application, the View layer component gives an
  interface to the application. Regardless if it is
  for users with a browser or for another
  application using Web services. View layer is the
  bridge for getting the data in and out of the
  application.
• It does not have business logic, like calculating
  interest for a banking application or storing
  items in a shopping cart for an online catalog.
  It also does not contain any code for existing
  data to or retrieving data from a data source.
  Business logic is managed by the Model layer.
  View layer is more focused on the interface.

• Business Layer- It is also known as Business
  Logic or Domain Logic or Application Layer. The
  function of the business layer is to accept user
  requests from the browser, processes them, and
  determine the routes through which the data will
  be accessed. The workflows by which the data and
  requests travel through the back end lay encoded
  in a business layer.
• Data Access Layer- This layer is built to keep
  the code you use to pull data from your data
  store like database, flat files, or web services
  separate from business logic and presentation
  code. So even if you have to change data stores,
  you dont end up rewriting the whole thing.

Types of Web Applications

• Three primary types of web application
  architecture are
• Serverless Architecture A serverless
  architecture is a simple way to build and run
  applications and services without having to
  manage infrastructure. The application you deploy
  runs on servers, but all the server management is
  done by a third-party service provider like AWS.
  You dont need to provision, scale, and maintain
  servers in order to run your applications,
  databases, and storage systems.

• Single-Page Applications A single-page
  application or SPA is a type of web application
  architecture which interacts with the user by
  dynamically rewriting the current page rather
  than loading entire new pages from a server. By
  this way, one can avoid interruption of the user
  experience between successive pages which makes
  the application behave more like a desktop
  application.
• Microservices They can be called small and
  lightweight services which are responsible for
  executing a single functionality. The
  Microservices Architecture framework allows the
  developers working with it to not only enhance
  productivity but also speed up the entire
  deployment process.

Conclusion

• Along with technology, the architecture of web
  applications is also evolving and growing
  day-by-day. The overall effectiveness,
  responsiveness, and agility of a web application
  is defined by the type of model one chooses. It
  is highly recommended that you take time to
  consider all your business requirements before
  initiating the development process.
