title: Getting the grasp of Couchbase using memcached buckets
body: <p>The case I have is that I currently have 3 memcached instances running at 3 different servers. My application is currently at the same 3 different nodes. All the applications servers know of all the memcached servers, but if one of them goes down, I have no way of notice.
  The idea is to move the memcached servers to own nodes.</p>
  
  <p>I have begun to look at CouchBase as maybe an alternative of solving this, but are unsure of exactly it will work.</p>
  
  <p>Will it work so that I have a CouchBase cluster, on each application node, and then connect them to the different memcached servers, and CouchBase will then monitor and know which ones is alive? </p>
  
  <p>In that case, how does the application which are currently tied to the memcached instances know how to get the data if one of the memcached instances are down? Or is it CouchBase that will be the middle-man taking care of where to store it?</p>
