What is an SDK?

An SDK, or Software Development Kit, is a comprehensive suite of tools designed to aid developers in creating applications for specific platforms or devices, often encompassing components such as compilers, code libraries, debugging tools, and extensive documentation. These kits enable developers to efficiently build and integrate applications by providing pre-built code and APIs that facilitate interaction with operating systems, cloud services, or specific hardware. Common examples include iOS, Android, and AWS SDKs, which support app development in their respective ecosystems. Enterprises leverage SDKs to meet particular needs, such as automating tasks or integrating with their platforms, thereby streamlining the development process and ensuring reliable application performance. SDKs can be open or closed, with open SDKs predominating due to the rise of mobile and cloud technologies, while closed SDKs are typically used for specialized hardware or proprietary systems under NDAs.
