There are several best practices to follow when it comes to developing scalable applications and systems, including using the right programming languages, frameworks, tools, and methodologies. The most important thing about scalable application development is providing users with an enjoyable experience while also supporting the needs of your business or company as it grows in scale and size. If you keep these best practices in mind, your application will be ready to handle millions of users, no matter how big they are or how fast they grow.


Every business, from the smallest to the largest, needs an application that can grow with the company. But how do you know when it's time to start looking for a new one? And how can you tell if what you're using is scalable? Scalability is a measure of how well an application can grow as your business grows. It is important because as your business continues to evolve, so too must your app. There are many things that contribute to scalabilities, like data storage, data retrieval, and processing speed.

What is a Scalable Application?

A scalable application is an application that can be easily scaled to meet the needs of a larger user base. This is accomplished by designing the software for horizontal scaling, which means it can manage a larger load on more servers than previously needed. A common misconception about scalable applications is that they only need to scale up from one server to multiple servers. Although this is true, it does not take into account the fact that a scalable application will also need to scale out when there are too many users for one server.

The framework used in Scalable Application

The best practice for developing scalable applications is to use a microservices framework. These frameworks include a set of tools that allow developers to quickly create, deploy, scale, and manage their applications. The Top Microservices Frameworks are many including Spring Boot, which has released new features that make it easier than ever to build enterprise-ready web-based services with Spring Framework 5.

Characteristics of a Scalable Application

The characteristics of a scalable application are as follows:

- The application is designed to handle an increasing number of requests. - The application uses components that can be added or removed without negatively affecting the rest of the system. - Scalability is achieved by removing bottlenecks in the system, typically by adding more hardware resources, such as CPU power, memory, disk space, or bandwidth, to handle increased demand.

 - Scalability characteristics, as well as performance characteristics, can be designed into applications by following scalable design patterns. These scalable design patterns are guidelines that address common architectural problems in designing large-scale systems. Some commonly used design patterns include command/query responsibility segregation, event sourcing, CQRS, and event storming. Not all of these patterns will apply to every type of application you’re building.

Designing for Scalability

One of the most important considerations when designing for scalability is how your application will deal with increases in the volume of use. For instance, what happens when someone shares your social media post with their followers?

Best Practices for Scalable Application Development

One of the best practices for scalable application development is to be mindful of your codebase. Think about what you need for a framework for scalability before you write any code, so it doesn't have to be retrofitted later on. There are many frameworks that are focused on scalability (e.g., Apache Kafka, Apache Hadoop), and there are also some that offer scaling as an option (e.g., Node). You will want to Hire web developers who are experienced in this area of top microservices frameworks, including Docker Swarm, Mesos, Kubernetes, RancherOS, and CoreOS.


The best way to start developing a scalable application is to use the best frameworks that exist today. Top microservices frameworks include Apache Kafka, Apache Spark, Apache Mesos, and Akka. These frameworks are designed to provide a scalable architecture for the application that doesn’t require much work on the developer’s part. This will ensure that your application can scale up or down with ease when needed.
