Which PaaS-like service lets developers simply upload application code while AWS automatically handles server provisioning, capacity adjustment, load balancing, and deployment?
Selecting a PaaS-like service that automates application deployment and platform management.
AWS Elastic Beanstalk
Correct. AWS Elastic Beanstalk is a service that provisions and deploys the infrastructure needed to run an application as soon as the code is uploaded. Developers can focus on the application without managing infrastructure, and they can still adjust the underlying configuration when needed.
AWS CloudFormation
AWS CloudFormation is an IaC service that builds infrastructure defined in a template.
Users must describe the resource configuration in a template, so the PaaS-like experience of 'just upload code and the environment is configured and deployed automatically' is provided by Elastic Beanstalk, and this is incorrect.
AWS Lambda
AWS Lambda is a serverless service that runs function-level code in response to events.
It targets short-lived function execution, so the requirement to automatically configure the entire runtime environment of a web application (server configuration, capacity adjustment, load balancing) is met by Beanstalk, and this is incorrect.
Amazon Lightsail
Amazon Lightsail is a service that provides simple virtual servers (VPS) at a flat rate.
Servers are provided, but it is not a PaaS-like mechanism that automatically handles application deployment, capacity adjustment, and load balancing, so it is incorrect.
'Just upload code' and 'automatic provisioning and deployment of the platform' point to Elastic Beanstalk (PaaS-like). Distinguish it from serverless functions (Lambda) and simple VPS (Lightsail).
