  [IMPORTANT]
  
negative.code: In a highly available {product-title} cluster with external etcd, a master host
  should have 1 CPU core and 1.5 GB of memory, on top of the defaults in the table
  above, for each 1000 pods. Therefore, the recommended size of master host in an
  {product-title} cluster of 2000 pods would be 2 CPU cores and 3 GB of RAM, in
  addition to the minimum requirements for a master host of 2 CPU cores and 16 GB
  of RAM.
  
  When planning an environment with multiple masters, a minimum of three etcd
  hosts as well as a load-balancer between the master hosts, is required.
