Business is peaking, traffic is increasing, and you are all set to maximise your revenue. But is your application ready to handle the increased user traffic? What if your application isn’t ready to handle the new workload?

Are you having scalability issues with your application as your business expands and traffic grows? Slow performance, longer wait times, and dissatisfied users can all result from your application’s inability to satisfy the changing expectations of its users. This typically causes users to abandon the application, which means lost revenue and reduced engagement for your business. To prevent these issues, application owners must understand how to develop a scalable and user-friendly application.

At Mallow, we have extensive experience building applications of various sizes across different domains. We understand the significance of scalability for application owners and the challenges they face in meeting the needs of their users.

This article aims to offer valuable insights into the crucial steps that guarantee the scalability of your Ruby on Rails application. By grasping the significance of scalability and adhering to our expert guidance, you can create and maintain a high-performance application that effectively engages users and ensures the prosperity of your business.

The scalability of a Ruby on Rails application refers to its ability to handle increased workloads, user traffic, and growing data volumes without sacrificing performance or functionality.

Without proper scalability measures, an application can become slow, unresponsive, and even crash under a heavy load, resulting in a bad user experience, loss of revenue, and damage to the brand’s reputation.

A scalable Ruby on Rails application can seamlessly accommodate higher demand and adapt to changing circumstances without experiencing significant performance degradation or system failures. This includes efficiently scaling resources, such as servers and databases, to meet growing requirements, as well as implementing optimisation techniques to ensure smooth operation and responsiveness as the application and its user base expand. Therefore, having a scalable Ruby on Rails application is crucial for the success and sustainability of the application.

The scalability of an application is influenced by its architecture, with a well-designed one allowing for accommodating higher loads and traffic, whereas a poorly designed architecture may hinder scalability.

Moreover, the choice of hardware and infrastructure to host the application can impact its scalability. It is crucial for applications to effectively utilise server resources, such as CPU and memory, to ensure they can handle increased traffic. Moreover, adhering to coding best practices aids in efficiently using hardware resources.

The application should efficiently use database queries to reduce the load on the database server. This can involve optimising queries to use indexes, reducing the number of queries required to generate a page, and minimising the data retrieved from the database.

This plays a vital role in ensuring the scalability of a Ruby on Rails application. By storing frequently accessed data or the data produced from expensive operations in memory, caching reduces the load on the underlying resources such as the database or external services. This helps to reduce resource utilisation and minimises the response time for subsequent requests. This allows the application to handle a higher volume of traffic without experiencing performance degradation.

Caching can be implemented at various levels, such as page caching, action caching, fragment caching, or database query caching. Each level targets specific areas where caching can have the most significant impact.

The appropriate use of concurrency like multi-threading, number of processes, maximum request size, and other web servers and application server tuning parameters will influence the application’s scalability.
