If you’re familiar with the frustration of dealing with a poorly constructed web application or the challenges of providing tech support, you understand the importance of building a high-performing and scalable web application. However, with the numerous considerations involved, it can be overwhelming to determine the starting point.

This article aims to provide guidance on how to avoid common pitfalls that negatively impact user experience and waste resources. By following the best practices outlined below, you can ensure that your web applications meet performance expectations and keep customers coming back for more.

Best Practices for High-Performance and Scalable Web Applications to help you build better web applications, here are some of the top best practices to consider:

Thorough Requirements Analysis

Before beginning the development process, it is crucial to thoroughly assess the needs and specifications of the web application. Gather input from stakeholders and team members to ensure that all requirements are taken into account. A comprehensive understanding of the project goals will set the foundation for a successful outcome.

Choosing the Right Technology Stack

The technology stack you choose will play a significant role in the performance and scalability of your web application. Consider the tools and platforms that your organization is already familiar with and comfortable using. To ensure compatibility, it may be advantageous to use a hardware-based load balancer. When selecting a database, consider options beyond the default MySQL and explore plugins that are available. The goal is to create a user experience that is seamless and efficient.

Enhance Security Measures

Securing your web application is of utmost importance. Though it is impossible to guarantee complete security, there are several ways to minimize the risk of security breaches. Start by setting up a robust firewall to block unauthorized access to your application. Implement real-time user directory updates to ensure the information is up-to-date. Ensure that the application is only accessible by authenticated users by implementing authentication and role management.

Prepare for Scalability

Scalability refers to the ability of your web application to handle high volumes of traffic and peak usage periods without affecting performance. To achieve scalability, design your application to handle increased traffic in the future without adding complexity. Avoid blocking access to the database during peak times to ensure seamless performance. By preparing your web application for scalability, you can provide a smooth user experience even during periods of high traffic.

Develop with the End-User in Mind

When building your web application, always keep the end-user in mind. Consider the user experience and how they will interact with the application. For example, if you have created a contact form, think about what the user's objectives will be - making new contacts, transferring existing ones, etc. This end-user perspective is essential in creating an application that is both user-friendly and efficient.

Assemble the Right Development Team

Having the right development team is crucial to the success of your web application. Ensure that your organization has a team of skilled developers who can support and maintain the application, and fix any issues that may arise. The team should be able to manage their workloads and be self-sufficient in their tasks. The size of the team should also match the scope of the project.

Adhere to Coding Guidelines and Conventions

Adhering to coding standards and conventions can make your code more readable and easier to maintain. There are several industry-recognized guidelines and conventions such as those published by the PHP WhatsApp Foundation or the CodeIgniter Framework. Following these best practices will ensure that your code is well organized and easy to understand.

Refine Code Architecture for Scalability and Maintainability

Careful consideration of the code architecture is crucial in developing a scalable and maintainable web application. Think about the functions that your application provides and how users will interact with it. You could opt for a vertical scaling architecture, a horizontal scaling architecture, or a combination of both.

Enhance Network Infrastructure for Improved Performance

The network layer often goes overlooked in virtualized environments, where multiple servers run on a single low latency network. However, it is important to carefully examine the network settings in this environment and optimize them for performance. Utilize network-aware database systems, such as Memcached or Redis, to cache data between servers. Proper tuning of these caching systems can prevent traffic bottlenecks and keep track of what is being cached. By maximizing memory usage and disabling unnecessary interfaces, you can ensure optimal performance and reliability.

Test, Test and Test Again

Once the web application has been created, it's essential to assess its performance. Testing can be done using mock users to see how the application performs under high traffic conditions. Tools such as WebPageTest.org can be used to test the application's load and simulate different scenarios. If you're testing an existing or legacy application, consider using a tool such as JMeter to ensure that the application works as intended in all implementations. Remember, if your application is not scalable, high traffic could affect real users' performance.

Making Your Web Application High-Performance

Building high-performance web applications can be challenging, but by understanding the data and processes involved, it's possible to achieve optimal results. To start, gather information from other developers in your organization who are working on similar projects.

Additionally, consider the customer's needs and how they can be met with your web application. By considering these factors, you can invest your resources effectively and build a high-performing web application.

Do not forget to scale reliably, while you move fast and break things to achieve high performance, let Zenduty handle the incidents for you to stay on top of critical alerts.
