Ideal use case

m3.medium 1 3.75 $ 49.05 General Purpose – Fixed Performance

c3.large 2 3.75 $ 76.86 Compute Optimized – Fixed Performance

t2.medium 2 4 $ 38.07 General Purpose – Burstable Performance

If t2 works for your workload:

~22% savings switching from m3.medium to t2.medium.

~50% savings switching from c3.large to t2.medium.
