100 servers to do what?

For production:
- 3 master nodes
- x data nodes (depending on what you are going to do)
- y client nodes (depending on what you are going to do)
May I suggest you look at the following resources about sizing:

thankyou for the reply,
I have to take logs from more than 100 live servers with the help of the filebeat.
I want to know about the architecture i.e the no of data nodes and master nodes and the no of client nodes.
