You are the architect of the ACME shipping group. You are responsible for designing autoscaling solutions. You are preparing for Black Friday sale, which in history brings loads of additional traffic to the current webserver, which is running in full production mode 24x7. Which autoscaling pattern would be the best fit?
Predictable autoscaling is correct, as you know there will be a huge spike in traffic as per recent years. Off and On is not an option, as you cannot turn off a 24x7-production system. Adding resources autoscaling will not suffice as you are unsure of when to add additional resources and not sure how much more resources. Unpredictable autoscaling is not ideal you are aware that the traffic load will increase, however, this might be considered a second option.
