Which service runs your code on a high-availability compute infrastructure and handles server and OS maintenance, capacity provisioning, automatic scaling, and logging?

• A. Amazon Lightsail
• B. AWS Outposts
• C. AWS Lambda
• D. AWS Elastic Beanstalk

Answer: (C)

This is about serverless compute—running code without managing servers or operating systems. AWS Lambda fits this because it runs your code on highly available compute infrastructure and takes care of server and OS maintenance, capacity provisioning, automatic scaling, and logging for you. You write the function, pick a runtime, and Lambda scales automatically in response to events; you don’t provision or administer servers, and logs flow to CloudWatch automatically. Other options provide managed infrastructure but still involve some server management or fixed environments: Lightsail uses simple virtual servers with fixed instances; Outposts brings AWS services to on-premises hardware; Elastic Beanstalk manages application deployment on top of EC2 instances but still relies on underlying servers that you don’t fully escape managing. Lambda is the best fit for fully managed, serverless compute that handles the heavy lifting automatically.
