AWS Launches EC2 C8g and M8g Instances with Graviton4 Processors
Amazon Web Services (AWS) has unveiled its new EC2 C8g and M8g instances, featuring the cutting-edge Graviton4 processors, designed to deliver a significant leap in performance and efficiency for a range of workloads. These new general-purpose and compute-intensive instances claim to offer up to 30% better performance than their predecessor models based on Graviton3 technology, albeit with an average cost increase of approximately 10% over the M7g and C7g generations.
Advancements in Processor Technology
The Graviton4 processors are developed by AWS’s subsidiary, Annapurna Labs, and present a powerful option for both memory-intensive and general-purpose computing. While the Graviton4-based X8g instances have been available for several months, the C8g and M8g classes represent a widely anticipated addition to AWS’s already robust EC2 lineup.
These newly launched M8g instances are designed for versatile use cases such as standard web hosting, while the C8g instances are optimized for compute-heavy tasks encompassing high-performance computing (HPC), batch processing, gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning inference, and ad serving.
Veliswa Boya, Senior Developer Advocate at AWS, emphasizes that “the C8g and M8g instances are ideal for Linux-based workloads," particularly containerized and microservices applications leveraging platforms like Amazon Elastic Kubernetes Service (EKS) and Amazon Elastic Container Service (ECS). They support a variety of programming languages including C/C++, Rust, Go, Java, Python, .NET Core, Node.js, Ruby, and PHP.
Enhanced Performance Metrics
The performance implications of the Graviton4 processors are noteworthy. When compared to the previous Graviton3 generation, AWS reports that:
- Database applications benefit from a 40% speed increase.
- Java application performance improves by 45%.
Furthermore, these instances deliver exceptional networking capabilities with up to 50 Gbps of network bandwidth and 40 Gbps of Amazon Elastic Block Storage (EBS) bandwidth, outpacing the Graviton3 instances, which offered up to 30 Gbps and 20 Gbps, respectively.
Pricing Strategy Under Scrutiny
Despite the performance improvements, reactions from the tech community are mixed. Critiques have emerged regarding AWS’s pricing strategy, particularly concerning the rise in costs associated with migrating to the new instances. Corey Quinn, Chief Cloud Economist at The Duckbill Group, noted, "If I upgrade my dev/utility instance from its current c7g.large to a c8g.large, it will increase its cost by over 9%. The machine is usually bored; there’s no ‘but you make better price/performance gains’ argument to be had here—it’s strictly a price hike."
Current Availability and User Adoption
The new EC2 C8g and M8g instances have been rolled out in limited AWS regions including Ohio, Northern Virginia, Oregon, and Frankfurt. Some users have pointed out through forums like Reddit that availability may be restricted to select availability zones within these regions.
Prominent companies like SAP, Epic Games—the creators of Fortnite—and SmugMug have reportedly incorporated Graviton4-based instances into their operations, showcasing the evolving landscape of cloud computing capabilities.
Moving Forward
AWS’s push for enhanced sustainability and efficiency continues with these new offerings. However, the community response highlights a significant concern about cost versus performance. As users increasingly seek cost-effective solutions that do not compromise performance, the tech industry will be watching closely to see how AWS navigates this competitive landscape.
