09/28/2020, 4:43 PMyou are actually going to need to use an elasticacheReplicationGroup when working with Redis

09/28/2020, 7:48 PMWhy does it say `Multi AZ`disabled when you can see on the right that i have assigned it 3 AZs.
bitter-application-91815
09/28/2020, 7:49 PMAlso should i create a security group that has that redis port open for ingress and egress and assign it to it, I have placed it in 3 private subnets

09/28/2020, 7:56 PMyou will need to follow AWS guidance on that (re: security groups) - I am pretty sure you will need to use elasticacheSecurityGroup as a way to be able to get the security group added

09/28/2020, 8:01 PMre: multi-az, that looks to be something missing from the provider - can you open an issue and I can look into that?
