Amazon Web Services (AWS) has officially announced the general availability of its new low-cost, burstable Amazon EC2 T8i instances. Powered by custom sixth-generation Intel Xeon Scalable Processors, known by the codename Granite Rapids and available exclusively on AWS, these new instances are designed to deliver up to 30 percent better price-performance compared to the previous generation T3 instances. Aimed at a broad spectrum of low-to-moderate CPU utilization workloads, the T8i lineup provides an efficient and cost-effective compute option for developers, startups, and enterprise customers alike.
The introduction of the T8i instances addresses a crucial segment of cloud computing needs. Thousands of AWS customers routinely rely on lightweight workloads that demand small, economical compute configurations. These typical use cases span microservices architectures, low-traffic websites, development and testing environments, small databases, data processing jobs, and short-duration compute tasks. A primary reason for the popularity of the T-family of instances is its burstable performance model, which establishes a baseline level of CPU performance while granting applications the ability to burst above that baseline whenever demand spikes, utilizing accumulated CPU credits.
As organizations continue to modernize their digital infrastructure, migrate legacy systems from on-premises datacenters, adopt modern event-driven and microservices paradigms, and experiment with emerging workloads such as artificial intelligence inference, their demands evolve. Customers have increasingly requested newer generations of cost-optimized, small-footprint instances that deliver significantly better price-performance to reduce overall total cost of ownership. Furthermore, users require a seamless migration path that preserves their existing knowledge base, operational tooling, and architectural patterns.
The new T8i instances have been engineered specifically to address each of these operational and financial requirements. They maintain the familiar architectural characteristics that made the T3 family successful while integrating advanced silicon capabilities. Specifically, the integration of custom sixth-generation Intel Xeon Scalable Processors provides the foundational compute power needed to handle modern lightweight software stacks with greater efficiency.
In terms of physical and performance specifications, the T8i family offers four distinct sizes at launch: the t8i.nano, t8i.micro, t8i.small, and t8i.medium. Each of these instance sizes features two virtual CPUs (vCPUs) offered as a single physical core, preserving a specialized design that delivers unique vCPU-to-memory ratios. Specifically, T8i instances provide ratios such as 1:0.25, 1:0.5, and 1:1, proportions that are notably absent from standard general-purpose EC2 instance types, making them uniquely suited for memory-conscious lightweight applications.
Looking closely at the individual configurations within the lineup, the t8i.nano is equipped with 0.5 GiB of memory, a baseline performance of 5 percent per vCPU, and earns 3 estimated CPU credits per hour, while supporting network burst bandwidth up to 6.25 Gbps. Step up to the t8i.micro, and customers receive 1 GiB of memory, a baseline performance of 10 percent per vCPU, and 6 CPU credits earned per hour, alongside the same network burst bandwidth capabilities. The t8i.small doubles the memory configuration to 2 GiB, provides a baseline performance of 20 percent per vCPU, and accrues 12 CPU credits per hour. Finally, the t8i.medium maintains the same 2 vCPUs, 20 percent baseline performance, and 12 CPU credits earned per hour as the small variant, but expands the allocated memory to 4 GiB. All four sizes share a network burst bandwidth capacity of up to 6.25 Gbps.
Just like their T3 predecessors, T8i instances operate on the established CPU credit system and support both Standard and Unlimited credit configuration modes. In the Standard mode, an instance accumulates CPU credits when running below its baseline performance level and spends those credits when bursting above the baseline. In Unlimited mode, which serves as the default configuration for T8i instances, an instance can burst beyond its baseline for as long as needed, providing operational peace of mind for applications that may experience unpredictable traffic surges without risking performance throttling due to depleted credit balances.
For workloads that require larger instance sizes that scale well beyond the maximum offerings of the T8i tier—which tops out at the medium size—AWS recommends exploring alternatives such as the M8i Flex instances. These larger general-purpose options similarly offer up to 30 percent better price-performance than equivalent previous-generation instances while providing the flexibility to scale up to 16xlarge configurations as application demands grow.
The deployment of Amazon EC2 T8i instances is already underway, with general availability spanning multiple major AWS Regions across the globe. Customers in the United States can access the new instances in the US East regions covering Northern Virginia and Ohio, as well as the US West regions in Oregon and Northern California. Across the Asia Pacific region, availability includes Hyderabad, Malaysia, Mumbai, Seoul, Singapore, Sydney, and Tokyo. Additionally, the instances are available in Canada Central and across several key European hubs, including Frankfurt, Ireland, London, and Paris. Organizations seeking to check specific Regional availability or track upcoming geographic expansions can review the instance types listed within the CloudFormation resources tab of the AWS Capabilities by Region portal.
Purchasing options for T8i instances are designed for flexibility and ease of adoption. Customers can acquire them immediately via On-Demand instances and Spot instances, with support for Savings Plans expected to roll out in the near future. These instances are built for shared tenancy environments, meaning they do not currently support Dedicated tenancy or Dedicated Hosts. Furthermore, to help developers and organizations test and deploy lightweight applications with zero upfront costs, the t8i.micro and t8i.small instances are included as part of the AWS Free Tier. Detailed pricing information for all configurations can be found on the official Amazon EC2 pricing page.
Developers and systems administrators can begin provisioning and evaluating T8i instances directly through the Amazon EC2 console. AWS has also encouraged users to share their experiences, performance metrics, and feedback through AWS re:Post for EC2 or via their established AWS Support communication channels to help guide future optimizations and feature expansions.
