title: Are Amazon's micro instances (Linux, 64bit) good for MongoDB servers?
body: <p>Do you think using an EC2 instance (Micro, 64bit) would be good for MongoDB replica sets?</p>
  
  <p>Seems like if that is all they did, and with 600+ megs of RAM, one could use them for a nice set.</p>
  
  <p>Also, would they make good primary (write) servers too?  </p>
  
  <p>My database is only 1-2 gigs now but I see it growing to 20-40 gigs this year (hopefully).</p>
  
  <p>Thanks</p>
