Amazon EC2 T3 Instances

The next generation of burstable general-purpose instances that provide up to 30% better price performance over previous generations

T3 instances are the next generation burstable general-purpose instance type that provide a baseline level of CPU performance with the ability to burst CPU usage at any time for as long as required. Based on high frequency Intel® Xeon® Scalable processors and the AWS Nitro System, T3 instances are designed for applications with moderate CPU usage that experience temporary spikes in use.

T3 instances offer a balance of compute, memory, and network resources for a broad spectrum of general purpose workloads including micro-services, low-latency interactive applications, small and medium databases, virtual desktops, development environments, code repositories, and business-critical applications.

Features

Burstable CPU Performance

T3 instances provide a baseline level of CPU performance with the ability to burst above the baseline using CPU credits. T3 instances accumulate CPU credits when a workload is operating below baseline threshold. Each earned CPU credit provides the T3 instance the opportunity to burst with the performance of a full CPU core for one minute when needed.  T3 instances are unlike any other burstable instance available in the market segment today in that customers can sustain high CPU performance for any period of time, whenever and however long required, and avoid application degradation if the instance exceeds its available CPU credits.

Unlimited and Standard Mode

T3 instances start in Unlimited mode by default, giving users the ability to sustain high CPU performance over any desired time frame while keeping cost as low as possible. For most general-purpose workloads, T3 Unlimited instances provide ample performance without any additional charges. If the average CPU utilization of a T3 instance is lower than the baseline over a 24-hour period, the hourly instance price automatically covers all interim spikes in usage. If the instance needs to run at higher CPU utilization for a prolonged period, it can do so for an additional charge of $0.05 per vCPU-hour. In Standard mode, a T3 instance can burst until it uses up all its earned credits.

 

Next Generation Platform

T3 instances are powered by the AWS Nitro System which includes a lightweight hardware-accelerated hypervisor, delivering practically all of the compute and memory resources of the host hardware to the instances. T3 instances also feature the latest high frequency Intel Xeon Scalable processors which combined with the AWS Nitro System result in up to a 30% better price to performance improvement over T2 instances. These new Xeon Scalable processors feature new AVX-512 instructions that can further accelerate performance. T3 instances also support Enhanced Networking with up to 5 Gbps in network bandwidth using the Amazon Elastic Network Adaptor.

T3 instances accumulate CPU credits when operating below baseline threshold. One CPU credit is equal to one vCPU running at 100% utilization for one minute. See T3 Unlimited documentation for details on CPU Credits and how they work.
