AWS Marketplace, a curated digital catalog with over 4,800 solutions, announced a feature that makes it easier for you to find relevant third-party solutions directly in the AWS console. Now, third-party solutions from AWS Marketplace are automatically filtered and listed in the left hand navigation panel based on the AWS service console you’re in. This means that you see only Machine Learning models and algorithms in the Amazon SageMaker console. You can also use the new search bar or filtering options to look for specific solutions without leaving the console.
