So, there might be one host which is a slightly more perfect match than others, but you don\u0027t want that host to be a new instance creation hot spot so you have a subset bigger than one.","commit_id":"5c7bf57f650aa13e0643c2612f95cea57fd84705"},{"author":{"_account_id":5441,"name":"Andrew Laski","email":"andrew@lascii.com","username":"alaski"},"change_message_id":"5f326c6cd272687dc1c295eb367368dc9196352a","unresolved":false,"context_lines":[{"line_number":28,"context_line":"New instances will be scheduled on a host chosen randomly from a subset of the"},{"line_number":29,"context_line":"N best hosts, where N is the value set by this option.
