Howdy, I'm the author :) I definitely agree, for high traffic applications a compute or memory optimized instance are more optimal choices due to the consistent performance, especially when price isn't as much of a concern. In situations where cost is more of a concern and the application has "bursty" requirements for performance, I still believe the T2 instance has it's place. The guys over at Cloudonaut have an excellent article on the importance of T2 burst credits to maintain application performance. https://cloudonaut.io/burst-credits-of-t2-ec2-instances-need-monitoring/ https://cloudonaut.io/burst-credits-of-t2-ec2-instances-need... EDIT: The new T2 Unlimited option mentioned at the above article is also worth considering.
