Which AWS service provides a platform for hybrid applications?

AWS Outposts is the correct choice because it extends AWS infrastructure, services, and operating models to virtually any data center, co-location space, or on-premises facility. This service provides a fully managed, native AWS infrastructure that allows organizations to build hybrid applications, which can run critical workloads on-premises while still leveraging the power of the AWS cloud. By using AWS Outposts, businesses can achieve low-latency access to the applications and data that need to remain on-site due to regulatory, compliance, or data sovereignty reasons, all while using the same AWS tools and services in the cloud.

The other options serve different purposes that don’t specifically emphasize the hybrid application model. AWS IoT Core focuses on connecting Internet of Things devices to the cloud and managing their communications. AWS AppSync is primarily designed for building scalable GraphQL APIs that can integrate various data sources but does not necessarily cater to hybrid environments. Meanwhile, AWS Glue is a data integration service designed for extracting, transforming, and loading (ETL) data into data lakes, data warehouses, and other repositories, but it also does not focus on the hybrid application construct.
