What is t2 instance in AWS?

T2 instances are Burstable Performance Instances that provide a baseline level of CPU performance with the ability to burst above the baseline. The baseline performance and ability to burst are governed by CPU Credits. T2 instances accumulate CPU Credits when they are idle, and consume CPU Credits when they are active.

What is the difference between t2 and T3 AWS? T3 offers better value than T2, including extra CPU credits and better baseline performance, faster CPUs. The downside is the migration effort. The cost difference of the instance types between Windows and Linux is considerable and results in different optimal instance types: For Linux, T3 is priced lower than T2.
