AWS EC2 continues to come out with the next generation, and the cost compared to the same specifications decreases or the service performance increases compared to the same cost. However, as always, AWS leaves it to the customer's choice without detailed information, if you use the previous generation, you use the expensive price and low performance.
- T seires
t2 >>> t3 ( 30% improved performance/price )
- M series
m4 >>> m5 ( 14% improved performance/price ) >>> m6i ( max 15% computing improved performance/price) // max 20% improved memory bandwidth )
- R series
r4 >>> r5(2 times improved FLOPS per Core) >>> r6i ( max 15% computing improved performance/price // max 20% improved memory bandwidth )
- C series
c4 >>> c5( 25% improved performance/price ) >>> c6i ( max 15% improved computing preformance/price )
