Basics of Scalability

Modular Design, Event-Driven Architecture & Caching

In my previous post, I discussed the three main fundamentals of reliable software.

You need to ensure that your software can handle growth without big changes. This is scalability. Consider the following to improve scalability of your software. 

Microservices: Break down your application into small, modular, manageable parts. These are also known as microservices. Each component (microservice) can be developed, built, and deployed independently.

Event-Driven Architecture: Asynchronous processing is key here. Changes in state trigger events that perform some tasks. Tasks run on their own, without waiting. Design your app this way.

Caching: Identify the most frequently accessed data, store a copy of it. This reduces load on primary data sources like databases and external APIs.
