AWS Cloud Map supports configuring negative caching for DNS queries

AWS Cloud Map now provides the ability to configure the negative caching for DNS queries. AWS Cloud Map is a cloud resource discovery service that allows customers to define custom names for their application resources, such as Amazon Elastic Container Services (ECS) tasks, Amazon Elastic Compute Cloud (EC2) instances, Amazon DynamoDB tables, or any other cloud resource. They can then use these custom names to discover the network location and metadata of these cloud resources from their applications using AWS SDK and authenticated API queries.
