API (Application Programming Interface)

An API, or Application Programming Interface, allows different software applications to communicate with each other by defining rules and protocols for requests and responses. APIs play a crucial role in modern software development, enabling integration between systems, services, and platforms. Whether connecting microservices in a cloud infrastructure or building custom applications on top of existing services, APIs streamline processes and enhance functionality. Popular APIs include REST and GraphQL, often leveraged in cloud-native and DevOps environments.
