Amazon Web Services (AWS) has announced the immediate availability of its new Amazon EC2 C8id, M8id, and R8id instances, marking a significant advancement in cloud computing capabilities for I/O-intensive applications. These instances build upon the foundation of the existing eighth-generation C8i, M8i, and R8i families, which debuted last year, by integrating substantial NVMe-based SSD block-level instance storage directly connected to the host server. This strategic enhancement is designed to deliver unparalleled performance for demanding workloads such as high-performance databases, real-time analytics, and caching layers.
Core Enhancements and Performance Metrics
The introduction of the ‘d’ suffix in the instance names signifies the inclusion of dedicated, high-speed local NVMe storage, a critical feature for applications requiring ultra-low latency and high throughput for temporary data. These new instances are engineered to provide a substantial performance leap over their sixth-generation predecessors. Key performance indicators reveal up to 43% higher compute performance and 3.3 times more memory bandwidth. For I/O-intensive database workloads, users can expect up to 46% higher performance, while real-time data analytics queries can execute up to 30% faster.
The C8id, M8id, and R8id instances are powered by custom Intel Xeon 6 processors, exclusively available on AWS, which feature a sustained all-core 3.9 GHz turbo frequency. This custom silicon design ensures optimal performance and efficiency within the AWS ecosystem, offering the highest performance and fastest memory bandwidth among comparable Intel processors in the cloud. The integration of these powerful processors with the new local NVMe storage creates a potent combination, addressing the growing demand for accelerated processing of large datasets and rapid transaction handling.
Scalability and Configuration Options
One of the most compelling aspects of these new instances is their enhanced scalability. The C8id, M8id, and R8id families now scale up to the 96xlarge size, a substantial increase from the 32xlarge maximum of the sixth-generation instances. This expansion translates into significantly more resources per instance, with configurations offering up to 384 virtual CPUs (vCPUs), 3 TiB (tebibytes) of memory, and an impressive 22.8 TB of local NVMe storage. This expanded capacity facilitates the consolidation of larger workloads onto fewer instances, driving greater operational efficiencies and simplifying application scaling.
Beyond the virtualized instances, AWS is also offering two bare metal sizes: metal-48xl and metal-96xl. These bare metal configurations provide customers with direct access to the underlying server hardware, bypassing the hypervisor. This is particularly beneficial for workloads with strict performance, security, or regulatory compliance requirements that demand isolation and uncompromised access to physical resources. Use cases include high-performance computing (HPC), specialized database deployments, and scenarios where custom hypervisors or operating systems are necessary.
The instances are available in a comprehensive range of 11 sizes per family, ensuring that customers can precisely right-size their compute resources to match their application demands. The memory configurations vary across the families to cater to different workload profiles: C8id instances are optimized for compute-intensive tasks, M8id instances offer a balanced mix of compute and memory for general-purpose applications, and R8id instances are memory-optimized for workloads requiring large in-memory datasets.

These specifications underscore the significant investment AWS has made in providing granular control and robust performance for diverse enterprise applications. The increased network and EBS bandwidths, peaking at 100 Gbps and 80 Gbps respectively for the largest instances, ensure that data transfer is not a bottleneck for high-demand workloads.
Underlying Technology: AWS Nitro System and Instance Bandwidth Configuration
The C8id, M8id, and R8id instances leverage the cutting-edge AWS Nitro System, a foundational technology that underpins modern EC2 instances. The Nitro System offloads virtualization, storage, and networking functions to dedicated hardware and software, freeing up CPU resources for customer workloads and enhancing overall performance and security. This architecture contributes significantly to the instances’ consistent performance and robust security posture.
Further optimizing resource allocation, these instances support the Instance Bandwidth Configuration (IBC) feature. IBC allows users the flexibility to dynamically allocate resources between network and Amazon Elastic Block Store (Amazon EBS) bandwidth. By scaling network or EBS bandwidth by 25% according to specific workload needs, customers can achieve optimal resource utilization and cost efficiency for each application. This capability is particularly valuable for hybrid workloads that might have fluctuating demands for either network I/O or persistent storage I/O.
To fully capitalize on the performance and capabilities of these new instances, users must ensure their Amazon Machine Images (AMIs) include drivers for the Elastic Network Adapter (ENA) and NVMe. AWS notes that all current generation AWS Windows and Linux AMIs come with the AWS NVMe driver installed by default, simplifying the adoption process for most users. For custom AMIs, manual installation of AWS NVMe drivers may be required.
Background Context: The Evolution of EC2 and Strategic Innovation
The launch of the C8id, M8id, and R8id instances represents a natural progression in AWS’s relentless pursuit of innovation in cloud infrastructure. Since its inception, Amazon EC2 has been at the forefront of cloud computing, offering a scalable, on-demand compute capacity that has revolutionized how businesses deploy and manage applications. The "i" in the instance naming convention denotes the use of Intel processors, reflecting AWS’s long-standing partnership with Intel to deliver high-performance, customized silicon for its cloud platform. The "d" suffix, as noted, signifies the integration of local NVMe storage, a feature that has become increasingly critical for modern data-intensive applications.
This latest release follows the successful launch of the C8i, M8i, and R8i instances last year, which already provided a significant boost in performance through custom Intel Xeon 6 processors. By adding local NVMe storage, AWS is directly addressing the performance bottlenecks associated with network-attached storage for certain use cases, offering a more comprehensive solution for highly demanding I/O profiles. This iterative development cycle underscores AWS’s commitment to continuously enhancing its service offerings based on customer feedback and evolving technological requirements.
