Clarification about Solr Cloud and Shard

[Rekha]

Dear Solr Team, I need following clarification from you, please check and give 
suggestion to me, 1. I want to store and search 200 Billions of documents(Each 
document contains 16 fields). For my case can I able to achieve by using Solr 
cloud? 2. For my case how many shard and nodes will be needed? 3. In future can 
I able to increase the nodes and shards? Thanks, Rekha Karthick
