_Are there any_ advantages or _disadvantages_ to running ElasticSearch  
over one Single Server or Clustering it ?

Also could somebody help me how many entries and query request/sec an AWS  
Ec2 Small Instance would be able to perfom well ?

The advantages of clustering are taking advantage of replicas for  
high-availability, distributed indexing and querying for performance,  
and memory reduction per server since one single node does not contain  
the entire index (if configured so).

Number of requests per second is highly dependent on the use case. You  
can have large documents, but small indices. Queries can contain  
facets (which populate the field cache and therefore memory) or not.  
One size does not fit all.

Cheers,

Ivan
