Introduction to API and API Gateway

What is an API?

In today's digital landscape, APIs (Application Programming Interfaces) have become an integral part of businesses and organizations that rely on software systems. They provide a way for different software systems to communicate with each other, share data, and perform specific functions. In this blog series, we will explore the basics of APIs and dive into the reasons why an API Gateway is so powerful.

What is an API Gateway?

An API Gateway is a server that acts as an intermediary for API requests. It acts as a reverse proxy, routing requests from clients to the appropriate backend services, and then returning the response back to the clients. The API Gateway acts as a layer of security, protection, and management for APIs. It provides a number of services, including authentication, authorization, rate limiting, caching, and transforming requests and responses. The API Gateway also serves as a central location for monitoring, logging, and analyzing API usage, providing insights into performance and usage patterns.

In summary, the API Gateway provides a centralized, unified access point for clients to interact with backend services, while improving security, reliability, and scalability of the APIs.
