- - - - Multi-AZ with automatic failover of a failed primary cluster to a read replica in Redis
        clusters that support replication
      - With multi-Az, should enable 2 nodes
    - - Replica nodes use asynchronous replication mechanisms to keep synchronized with the primary
        node.
      - REad only function
    - - Redis Shard - a grouping of one to six related nodes. A Redis (cluster mode disabled)
        
        cluster always has one shard. A Redis (cluster mode enabled) cluster can have 1–90
        
        shards.
        
        ■ A multiple node shard implements replication by have one read/write primary
        
        node and 1–5 replica nodes.
        
        ■ If there is more than one node in a shard, the shard supports replication with one
        
        node being the read/write primary node and the others read-only replica nodes.
    - - Need to install REd clisnt on EC2 to access Redis
- - - - Need to configure a role in the DAX cluster to allow DynamoDB to access The DAX
      - Need to configure role on EC2 to access DAX
      - Also need to go to microsoft visual studio and install a . NET app to act as dynamoDAX Application
        
        Then add the AWSSDK.DAX package to this application
        
        Next add some sample code that use the SDK package to retrive item from dynamoDB DAX cluster
    - - Integrate DynamodB DAX into .NETApp
