Starting today, new Amazon Elastic Compute Cloud (Amazon EC2) C5a instances featuring 2nd generation AMD EPYC™ processors running at frequencies up to 3.3 GHz are generally available. C5a instances are variants of Amazon EC2’s compute-optimized (C5) instance family and provide high performance at 10% lower cost over comparable instances. C5a instances deliver leading x86 price-performance for a broad set of compute-intensive workloads including batch processing, distributed analytics, data transformations, log analysis, and web applications.
AMD-based EC2 instances were first available in November, 2018 and have expanded to include 5 instance families (M5a, M5ad, R5a, R5ad, and T3a) spanning more than 15 global regions in North America, South America, Europe, Asia Pacific, and GovCloud. Customers are using AMD-based instances for a diverse set of workloads that range from scale-out microservices to large memory intensive databases and simulations. Customers benefit from the lower cost that AMD-based instances offer while better matching instance resources with the needs of their applications, and have asked for more AMD-based instance variants.
C5a instances deliver on this demand, and offer the lowest cost per x86 vCPU in the Amazon EC2 portfolio. C5a instances are available in eight virtualized sizes with up to 96 vCPUs and up to 192 GiB of memory. Disk variants, C5ad, which come with fast, local NVMe instance storage, and bare metal variants, C5an.metal and C5adn.metal, which will have access to 100 Gbps of network bandwidth, are coming soon.
C5a instances are available today in the US East (N. Virginia, Ohio), US West (Oregon), Europe (Ireland, Frankfurt), and Asia Pacific (Singapore, Sydney) AWS Regions. The new instances can be purchased as On-Demand, Reserved, Spot Instances or as part of a Savings Plan.
