Now Available – AMD EPYC-Powered Amazon EC2 T3a Instances
|
The AMD EPYC-powered T3a instances that I promised you last year are available now and you can start using them today! Like the recently announced M5ad and R5ad instances, the T3a instances are built on the AWS Nitro System and give you an opportunity to balance your instance mix based on cost and performance.
T3a Instances
These instances deliver burstable, cost-effective performance and are a great fit for workloads that do not need high sustained compute power but experience temporary spikes in usage. You get a generous and assured baseline amount of processing power and the ability to transparently scale up to full core performance when you need more processing power, for as long as necessary. To learn more about the burstable compute model common to the T3 and the T3a, read New T3 Instances – Burstable, Cost-Effective Performance.
You can launch T3a instances today in seven sizes in the US East (N. Virginia), US West (Oregon), Europe (Ireland), US East (Ohio), and Asia Pacific (Singapore) Regions in On-Demand, Spot, and Reserved Instance form. Here are the specs:
| Instance Name | vCPUs | RAM | EBS-Optimized Bandwidth | Network Bandwidth |
| t3a.nano |
2 | 0.5 GiB | Up to 1.5 Gbps | Up to 5 Gbps |
| t3a.micro |
2 | 1 GiB | Up to 1.5 Gbps | Up to 5 Gbps |
| t3a.small |
2 | 2 GiB | Up to 1.5 Gbps | Up to 5 Gbps |
| t3a.medium |
2 | 4 GiB | Up to 1.5 Gbps | Up to 5 Gbps |
| t3a.large |
2 | 8 GiB | Up to 2.1 Gbps | Up to 5 Gbps |
| t3a.xlarge |
4 | 16 GiB | Up to 2.1 Gbps | Up to 5 Gbps |
| t3a.2xlarge |
8 | 32 GiB | Up to 2.1 Gbps | Up to 5 Gbps |
The T3 and the T3a instances are available in the same sizes and can use the same AMIs, making it easy for you to try both and find the one that is the best match for you application.
Pricing is 10% lower than the equivalent existing T3 instances; see the On-Demand, Spot, and Reserved Instance pricing pages for more info.
