The T3A instance family, generally available since April 25, 2019, features 1st Gen AMD EPYC 7571 processors with an all-core turbo up to 2.5 GHz. These General Purpose burstable instances, built on the AWS Nitro System, use CPU credits to handle temporary spikes in usage, offering a cost-effective alternative to T3 instances. They utilize high-performance EBS for storage and offer up to 5 Gbps of networking bandwidth, but do not include local instance storage.
