DIGITAL TRANSFORMATION – CHALLENGES IN WEB APPLICATIONS
Software is at the heart of your digital transformation journey, impacting customer experiences, operational processes and business models. It permeates every aspect of a modern business. Software allows you to improve and expand the way your business, products and services work. Sometimes, it even enables you to fundamentally restructure and transform them.
Web applications are an important aspect of modern software, providing great competitive advantage in your digital transformation. As Web applications are increasingly used to update and expand existing systems, and build new ones, newer ways of Web application development need to be considered to meet various complexities and challenges:
Today’s Web applications must be secure, and scalable to meet changes in demand. They also need to be available 24x7 across the world, accessible from multiple devices and screen sizes.
Modern Web applications have higher user expectations and greater demands than ever before. The quality of your software is crucial. It can directly impact the financial goals of your business.
Your Web applications need to be flexible to be able to respond quickly to fast-changing customer needs. Applications that provide superior user experience are key to staying competitive.
To meet market challenges, your business requires continuous improvement in value creation processes, backed by the adoption of new technologies. Agile and DevOps practices enable the accelerated delivery of quality, customer-focused software.
The key to staying competitive in today’s markets is to be open to adopting new technologies and methodologies. Your development teams need to be able to deploy new technologies continuously in existing and new business initiatives, rather than continue to rely on past investments.
Technology stacks form the backbone of modern Web application development. Selecting the right stack is key to the success of your project. Needless to say, a wrong one can negatively impact the project on effort, schedule, quality, and extensibility.
DIGITAL TRANSFORMATION – TRENDS IN WEB APPLICATIONS
Digital transformation is driving changes in Web applications. Today’s Web applications are:
- Optimized for hosting on the cloud (public cloud, private cloud, any cloud)
- Scalable to meet changing customer demand
- Cross-platform to support access from desktop (Linux®, macOS®, and Windows®) and mobile (Android™, iOS®) environments
- Modular and loosely-coupled to deploy only the required functionality, reduce their footprint and security vulnerability
- Easily tested with automated tests exercising the full application stack (including APIs, middleware, routing, model binding, filters, etc.)
- Support a combination of traditional Web application behavior, typically for content, and Single Page Applications (SPAs), for interactivity
- Support continuous integration (CI) and continuous delivery/deployment (CD)
Current Web application development involves the front-end comprising UI and the backend comprising services that power the front-end, a database and the required hardware infrastructure. Some of the current trends are described below.
In recent times, we have seen a lot of buzz around frameworks, which are mostly created by open source communities. Their main objective is to implement common functionality faster and easier. Frameworks are also a rich source of best practices from practitioners. Some popular libraries and frameworks include:
Bootstrap is a well-known CSS framework enables building responsive Web applications, which automatically adjust its layout for various screens sizes of mobile, tablet and desktop users.
Backbone, Knockout, Moment, Zepto
Backend Web frameworks helps developers to simplify and speed-up backend development for Web applications. Some popular frameworks include:
ASP.NET is an open-source server-side Web application framework to build dynamic Web sites, Web applications and Web services. Originally developed by Microsoft®, it provides useful features on top of .NET platform to help programmers in expediting development: base framework for processing Web requests, Web-page template syntax for building dynamic Web pages, libraries for MVC pattern, complete authentication system for internal and external identity providers.
Django is a Python-based open source web application development framework mainly suited for database-driven web application and websites. Its model-view-template (MVT) architecture makes it highly reusable and customizable. We can swap template framework, ORM and database to other alternatives. It follows MVVM pattern and all requests go through urlresolvers, middleware, view and context processors.
Node,js and Express
Laravel™ is a PHP framework that follows the MVC architecture pattern. Laravel attempts to simplify the most common tasks such as authentication, routing, sessions and caching by providing reusable code. It also provides command line tools and other helper functions to make the development an enjoyable and creative experience.
Ruby on Rails
Ruby on Rails® is the most popular Web framework written using the Ruby programming language. It runs on Linux and supports MVC architecture. Developers can add their code for views and models in environment tracks. It also provides a comfortable coding, compilation, and testing environment.
Hibernate, Pyramid, Phoenix, Spring
In addition to these, there are few more backend frameworks such as Flask, Hibernate, Pyramid, Phoenix and Spring.
MySQL, PostgreSQL, MongoDB
The most popular relational databases for Web applications include MySQL™ and PostgreSQL®, while MongoDB® is a popular, document oriented, non-relational database.
AWS, Microsoft Azure, Google Cloud
There are many other database options from cloud providers like AWS®, Microsoft Azure® and Google Cloud™.
To reduce traffic on the database, a Web application generally uses a caching system, such as Memcached and Redis.
