T3 instances use a burst pricing model that allows you to host general purpose workloads at low cost, with access to sustainable, full-core performance when needed. You can choose from seven different sizes and receive an assured baseline amount of processing power, courtesy of custom high frequency Intel® Xeon® Scalable Processors.
Our customers use them to host many different types of production and development workloads including microservices, small and medium databases, and virtual desktops. Some of our customers launch large fleets of T3 instances and use them to test applications in a wide range of conditions, environments, and configurations.
We launched the first EC2 Dedicated Instances way back in 2011. Dedicated Instances run on single-tenant hardware, providing physical isolation from instances that belong to other AWS accounts. Our customers use Dedicated Instances to further their compliance goals (PCI, SOX, FISMA, and so forth), and also use them to run software that is subject to license or tenancy restrictions.
Today I am pleased to announce that we are now making all seven sizes (t3.nano through t3.2xlarge) of T3 instances available in dedicated form, in 14 regions.You can now save money by using T3 instances to run workloads that require the use of dedicated hardware, while benefiting from access to the AVX-512 instructions and other advanced features of the latest generation of Intel® Xeon® Scalable Processors.
Just like the existing T3 instances, the dedicated T3 instances are powered by the Nitro system, and launch with Unlimited bursting enabled. They use ENA networking and offer up to 5 Gbps of network bandwidth.
You can launch dedicated T3 instances using the EC2 API, the AWS Management Console:
or via a CloudFormation template (set
dedicated in your Launch Template).
Dedicated T3 instances are available in the US East (N. Virginia), US East (Ohio), US West (N. California), South America (São Paulo), Canada (Central), US West (Oregon), Europe (Ireland), Europe (Frankfurt), Europe (London), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Asia Pacific (Mumbai), and Asia Pacific (Seoul) Regions.
You can purchase the instances in On-Demand or Reserved Instance form. There is an additional fee of $2 per hour when at least one Dedicated Instance of any type is running in a region, and $0.05 per hour when you you burst above the baseline performance for an extended period of time.
