AWS has announced that it is releasing its new line of EC2 T3a instances. Powered by AMD EPYC, these instances are built using the Nitro system, much like the previous m5ad and r5ad lines.
The T3a instances are designed to provide burstable computing performance while remaining cost-effective. While the baseline compute power is already high to begin with, you can scale up to gain additional power when you need, for as long as required.
T3a comes in seven sizes:
| Instance Name | vCPUs | RAM | EBS-optimized Bandwidth | Network Bandwith |
| t3a.nano | 2 | .5 GB | Maximum 1.5 GBps | Max 5 GBps |
| t3a.micro | 2 | 1 | Maximum 1.5 GBps | Max 5 GBps |
| t3a.small | 2 | 2 | Maximum 1.5 GBps | Max 5 GBps |
| t3a.medium | 2 | 4 | Maximum 1.5 GBps | Max 5 GBps |
| t3a.large | 2 | 8 | Maximum 2.1 GBps | Max 5 GBps |
| t3a.xlarge | 4 | 16 | Maximum 2.1 GBps | Max 5 GBps |
| t3a.2xlarge | 8 | 32 | Maximum 2.1 GBps | Max 5 GBps |
These t3a instances are available now in the following Regions: US East (N. Virginia), US West (Oregon), Europe (Ireland), US East (Ohio), and Asia Pacific (Singapore). You can order them as On-demand, Spot and Reserved.
