T2 instances accrue CPU Credits when they are idle, and use CPU credits when they are active.
The baseline performance and ability to burst are governed by CPU Credits.
Each T2 instance receives CPU Credits continuously at a set rate depending on the instance size.
T2 instances’ baseline performance and ability to burst are governed by CPU Credits.
Each T2 instance receives CPU Credits continuously, the rate of which depends on the instance size.
This capability provides baseline performance equivalent to 20% of a CPU core.
If at any moment the instance does not need the credits it receives, it stores them in its CPU Credit balance for up to 24 hours.Many applications such as web servers, developer environments and small databases don’t need consistently high levels of CPU, but benefit significantly from having full access to very fast CPUs when they need them.T2 instances are engineered specifically for these use cases.The FPGAs within the F1.16xlarge share access to a 400 Gbps bidirectional ring for low-latency, high bandwidth communication.Each v CPU is a hyperthread of an Intel Xeon core except for T2 and m3.medium.Use Cases Machine learning, high performance databases, computational fluid dynamics, computational finance, seismic analysis, molecular modeling, genomics, rendering, and other server-side GPU compute workloads.
