Replicate/synchronize backend instances across regions in Google Cloud

Question

I set up Cross-Region Load Balancing in Google Cloud and is working fine. How can I replicate/synchronize the back-end instances to have the exact same content (now each instance has it's own content) ? What should i search for ?

P.S.: i want the behavior of "Managed instance group" but cross region. Load-balance multiple instances on different regions, all with the same content.

There are 3 types of global load balancing (cross multiple regions) on GCE:

• HTTP(S) LB, working at L7 - HTTP(S) layer.
• SSL Proxy LB, working at L3 - SSL layer.
• TCP Proxy LB, working at L3 - TCP layer.

Just use the same instance template for all the managed instance groups.
