There's a lot of extra steps needed for this lab that aren't described. The cloud formation step never completed & no instruction was given for what to do to get around it, so the lab could not continue. And the fact that there is a timer on the lab means it is absolutely not self-paced at all.

Very interesting... although the Lab did not work when filling with twitter feeds... its not the cients computers but the server config... I changed this to make it work: [root@ip-172-31-38-251 redis]# diff index.js index.js.ori 438c438 < if (err.message === "ERR unknown command 'info'" ) { --- > if (err.message === "ERR unknown command 'info'" || err.message === "ERR wrong number of arguments for 'info' command" ) { [root@ip-172-31-38-251 redis]# pwd index.js /root/node_modules/redis [root@ip-172-31-38-251 redis]#
