# Shared Storage Models

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

When configuring shared storage, MuleSoft recommends placing the Redis shared storage service as
close to Flex Gateway as possible.

If the Redis shared storage service is available locally in the same cluster or the same Virtual
Private Cloud (VPC), a mutual authentication Transport Layer Security (mTLS) connection is not
required to communicate with the shared storage.

To configure the connection between Flex Gateway and the shared storage service, see:

- [Configure Shared Storage in Connected Mode](https://docs.mulesoft.com/gateway/1.9/flex-conn-shared-storage-config)

- [Configure Shared Storage in Local Mode](https://docs.mulesoft.com/gateway/1.9/flex-local-shared-storage-config)

The following diagrams use Kubernetes terminology, but you can extend the architecture to other
technology stacks that have the appropriate network controls applied.

You can place the Redis shared storage within the same Kubernetes cluster as Flex Gateway or
instantiated within the same VPC as Flex Gateway:

## Shared Storage in the Same Cluster

## Shared Storage in the Same VPC
