The API (Application Programming Interface) layer serves as the backbone for communication between clients and the backend services in modern internet-based applications.
It acts as the primary interface through which clients, such as web or mobile applications, access the functionality and data provided by the application. The API Layer of any application has several key responsibilities such as:
-
Process incoming requests from clients based on the defined API contract.
-
Enforce security mechanisms and protocols by authenticating and authorizing clients based on their credentials or access tokens.
-
Orchestrate interactions between various backend services and aggregate the responses received from them.
-
Handle responses by formatting and returning the result to the client.
Due to the central role APIs play in the application architecture, they become critical for the application scalability.
The scalability of the API layer is crucial due to the following reasons:
-
Handling Load and Traffic Spikes: As applications become popular, they encounter increased traffic and sudden spikes in user demand. A scalable API can manage the increased load efficiently.
-
Better User Experience: The bar for user expectation has gone up. Most users these days expect fast and responsive applications. A scalable API ensures that the application can support a high number of users without compromising performance.
-
Cost and Resource Optimization: Scalable APIs unlock the path to better resource utilization. Rather than provisioning the infrastructure upfront for the highest demand level, instances are added and removed based on demand, resulting in reduced operational costs.
In this article, we’ll learn the key concepts a developer must understand for API scalability. We will also look at some tried and tested strategies for scaling the API layer with basic code examples for clarity. Lastly, we will also look at some best practices that can help with scaling the API layer.
