AWS Certified Cloud Practitioner

Explanation

AWS Software Development Kit (SDK) is the correct answer because:

• AWS SDKs provide language-specific APIs that allow developers to integrate AWS services directly into their applications
• They offer programmatic access to AWS services through familiar programming languages like Python, Java, JavaScript, etc.
• SDKs handle authentication, request signing, and error handling automatically
• They enable developers to call AWS services directly from their application code

Why the other options are incorrect:

• AWS CodeDeploy: A deployment service that automates application deployments to various compute services, not for integrating AWS features into applications
• AWS Lambda: A serverless compute service for running code without provisioning servers, not specifically for integrating AWS service features
• AWS Batch: A batch computing service for running batch jobs at scale, not designed for integrating AWS service features into applications

The AWS SDK provides the most direct and efficient way for developers to integrate AWS service functionality into their applications programmatically.
