What AWS offering enables customers to find, buy, and immediately start using software solutions in their AWS environment?

AWS Marketplace is the correct answer because it serves as a digital catalog that allows customers to find, purchase, and deploy software solutions that are designed to run on the AWS infrastructure. Users can browse a wide range of software, including applications and services from independent software vendors, and these solutions can be easily integrated into their AWS environment. The convenience of immediate deployment and access simplifies the process for customers, allowing them to select the products that best meet their business needs without needing extensive technical know-how.

AWS Service Catalog, while it helps organizations create and manage catalogs of IT services, is primarily focused on offering approved products and services within an organization, rather than providing a marketplace for immediate use by customers. AWS CodePipeline is a continuous integration and delivery service that automates build, test, and deploy phases of application updates, but it doesn’t function as a marketplace for software solutions. Similarly, AWS CloudFormation is a service for modeling and setting up AWS resources and does not provide a way to find or buy software solutions.
