Starting today, memory-optimized Amazon EC2 R6gd instances with local NVMe-based SSD storage are available in South America (São Paulo). R6gd instances provide up to 40 percent better price-performance and up to 50% more NVMe storage GB/vCPU over comparable x86-based instances for memory-intensive workloads such as open-source databases, in-memory caches, and real time big data analytics. They are ideal for applications that need access to high-speed, low latency storage, as well as for temporary storage of data such as batch and log processing, and for high-speed caches and scratch files. Amazon EC2 R6gd instances are powered by AWS Graviton2 processors that are custom-designed by AWS to enable the best price performance in Amazon EC2.
