# dax ## Description DAX is a managed caching service engineered for Amazon DynamoDB. DAX dramatically speeds up database reads by caching frequently-accessed data from DynamoDB, so applications can access that data with sub-millisecond latency. You can create a DAX cluster easily, using the Amazon Web Services Management Console. With a few simple modifications to your code, your application can begin taking advantage of the DAX cluster and realize significant improvements in read performance. ## Available Commands * [create-cluster](create-cluster.md) * [create-parameter-group](create-parameter-group.md) * [create-subnet-group](create-subnet-group.md) * [decrease-replication-factor](decrease-replication-factor.md) * [delete-cluster](delete-cluster.md) * [delete-parameter-group](delete-parameter-group.md) * [delete-subnet-group](delete-subnet-group.md) * [describe-clusters](describe-clusters.md) * [describe-default-parameters](describe-default-parameters.md) * [describe-events](describe-events.md) * [describe-parameter-groups](describe-parameter-groups.md) * [describe-parameters](describe-parameters.md) * [describe-subnet-groups](describe-subnet-groups.md) * [increase-replication-factor](increase-replication-factor.md) * [list-tags](list-tags.md) * [reboot-node](reboot-node.md) * [tag-resource](tag-resource.md) * [untag-resource](untag-resource.md) * [update-cluster](update-cluster.md) * [update-parameter-group](update-parameter-group.md) * [update-subnet-group](update-subnet-group.md)
