Hi,
We currently have a 3-node ML cluster here in the US (let's call them US1,
US2, US3), with forest replication and failover enabled.
Should we need to expand to Europe, would the setup below achieve :
1. Traffic Localization (during normal operations)
2. Continued ML availability (in the event we ever need to bring one
cluster down for hardware or software upgrades / fixes)
?
*Draft EU Expansion Plan*
1. Set up another 3-node ML cluster in Europe (EU1, EU2, EU3), with forest
replication and failover enabled.
2. Also replicate the forests of the US cluster to the EU clusters and vice
versa
3. Direct US customers (via some geo DNS) to US webservers which use US1,
US2, and US3
- This would save US customer data to the forests on US1, US2, and
US3
4. Direct EU customers to EU webservers which use EU1, EU2, and EU3
- This would save EU customer data to the forests on EU1, EU2, and
EU3
5. Should the US ML Cluster ever go down, point the US websevers to the EU
ML Cluster
- I'm hoping this would activate and make available the data from
US1, US2, and US3 on EU1, EU2, and EU3. Am I correct ?
- Same thing should happen the other way around (i.e. if EU ML
cluster goes down, point EU webservers to US ML cluster)
Do you think this would work ?
Is there a better way to achieve our goals ?
How do we extend this model should the time come for us to expand to Asia ?
Regards,
Danny
