Hi All,

Can you please suggest me the best architecture approach for setting up a Cluster on AWS?

1.How many replications can we use in ELK Cluster for best architecture?

2.Can we use Spot Servers for storing data or they must be used for Master or Client in ES Cluster?

3.Can the Spot Servers be workers in ELK Cluster?

4.How many masters and what specification i can use in AWS(Medium/Small/Mini) in ELK Cluster?

1. How many can i set for Data nodes 1 Reserve(Large) and 1 Spot R3 Large can be used in ElasticSearch Cluster?

Pls suggest based on your experiences.

Thanks  
Jagan
