Amazon EC2 R9g and R9gd memory optimized instances are now available
Amazon EC2 now offers R9g and R9gd instances powered by AWS Graviton5 processors, delivering improved performance for memory-intensive workloads across multiple regions and pricing models.
Amazon Web Services announced the general availability of Amazon EC2 R9g and R9gd instances, which are powered by AWS Graviton5 processors. These instances are designed to optimize performance for memory-intensive workloads, including databases, analytics, and containerized applications. The new processors are positioned as the fifth generation of custom-designed CPUs, emphasizing cost efficiency for such workloads. The instances are available in select regions, including US East and EU (Frankfurt).
R9g instances support a wide range of workloads, including databases, in-memory caches, real-time big data analytics, and applications written in languages such as Java, Python, and Go. They are optimized for Linux-based environments, including containerized and microservices applications. R9gd instances additionally provide local NVMe-based SSD block-level storage, making them suitable for workloads requiring high-speed data access. Both instance types are built on the sixth-generation AWS Nitro System.
AWS Graviton5 processors deliver up to 25% better compute performance compared to previous-generation Graviton4-based instances. Benchmarks indicate performance improvements of up to 30% for databases, 35% for web applications, and 35% for machine learning tasks. The processors feature a cache size five times larger than their predecessors and offer the fastest memory available in cloud-based processor instances. These enhancements are intended to provide significant gains for memory-bound workloads.
The new instances incorporate the Nitro Isolation Engine, which uses formal verification to ensure mathematical assurance of workload isolation from other customers and AWS operators. This marks a new standard for cloud security, providing a higher level of assurance for workload isolation. R9g and R9gd instances are available through multiple purchasing models, including Savings Plans, On-Demand, Spot instances, Dedicated instances, and Dedicated hosts.
