Access Redis memory store mutliple VPCs

Question

Resources

Redis - Managed service (Memory store) - Only single Auth network can connect not multiple VPC

VPC - 1 - 192.168.0.0/24

VPC - 2 - 10.0.0.0/24

Redis <-> VPC 1 (Connected to Redis Private VPC Peering)

VPC 2 - GKE cluster Auto Pilot POD Redis - VPC 1 - VPC 2

Retirement is to connect from VPC 2 GKE Autopilot to Redis Instance through VPC 1 (as it’s authorised network)

Points to Note

• Can’t peer VPC 1 & VPC 2 using VPC Peering as want to keep service
• Separate No shared VPC service separation
• No Hub-spoke as VPC got created and only 2 there making it more simpler

Options in mind

• Twemproxy in VPC-1 with Internal Load balancer however how to connect to Internal LB from VPC 2 without peering ?
• VPN tunnel considering using limited IP range
• Custom VM gateway routing with IP Table

Please suggest if there is any better option available to connect from GKE autopilot in VPC 2 to Redis through VPC 1 without Peering.

Thanks

Answer 1

In your case, the simplest way this can be achieved is to create internal LB that requires peering. You can limit network connectivity of different VPCs by configuring the firewall rules and route tables. See this guide for steps to setup.
