T2 Instances Family The T2 family of instance types could be a good option

for development and test workloads, especially continuous integration (CI) and automated testing. T2 instance types are also a fit for single-server workloads where the server sits idle much of the time.

PitfallsUndersizing your servers- Build T1 servers that will spawn alarms constantly- Jenkins build time up to the roof- Rebuilding servers

Oversizing your servers- Wasted CPU/Memory processing & storage laying around- RDS storage that will eat you alive- Rebuilding servers

API hits- R53 TTL & Health check nightmares- Extreme monitoring gone wrong- Read. The. Fine. Print.

Pitfalls

Know your infrastructure“Hey! That team migration was amazing! Can’t we just do the same and move our entire storage to AWS?”

Understand your applications“So, I’m thinking about moving Project X to AWS. It shouldbe super simple!! It’s just a couple of APIs!”

Make your team know & understand that most migrations are an architectural challenge“Can it be done by next sprint?”
