Amazon Web Services (AWS) has always been at the forefront of cloud computing innovation. As of April 23, 2025, AWS launches Amazon Elastic Compute Cloud (EC2) M8g instances in the US West (N. California) region, providing businesses with a new level of processing power and efficiency. This guide will take you through everything you need to know about these new M8g instances, focusing on their features, benefits, and how to migrate your workloads.
What Are Amazon EC2 M8g Instances?¶
Amazon EC2 M8g instances are general-purpose virtual servers built on the AWS Nitro System and powered by advanced AWS Graviton4 processors. Designed for a wide range of workloads, including application servers, microservices, gaming servers, midsize data stores, and caching fleets, M8g instances provide substantial performance improvements over previous generations. The M8g series is particularly noted for delivering up to 30% better performance than the previous AWS Graviton3-based M7g instances.
Overview of AWS Graviton4 Processors¶
The heart of M8g instances lies in the new AWS Graviton4 processors. These processors are designed to provide optimal performance and energy efficiency across various workloads:
Enhanced Performance: AWS Graviton4 processors offer up to 40% faster performance for databases, 30% for web applications, and 45% for large Java applications compared to Graviton3 processors.
Increased Core Counts: The M8g instances provide larger instance sizes with up to three times more virtual CPUs (vCPUs) and memory than their M7g counterparts.
Networking Capabilities: With enhanced networking bandwidth of up to 50 Gbps and 40 Gbps bandwidth to the Amazon Elastic Block Store (EBS), the Graviton4 processors ensure that data-heavy applications run smoothly.
Key Features of M8g Instances¶
Performance and Efficiency¶
The M8g instances deliver exceptional performance with superior energy efficiency. AWS Graviton4-based instances are optimized for various workloads, aiming to deliver the best performance possible for a broad spectrum of applications.
Instance Sizes¶
M8g instances are available in 12 different sizes, catering to a wide range of needs—from small applications requiring minimal resources to large-scale applications demanding maximum compute capabilities.
Bare Metal Options¶
In addition to standard virtualization, M8g instances will be available in two bare metal sizes, allowing for even greater flexibility and control over the host environment.
Security Enhancements via Nitro System¶
Using the AWS Nitro System, EC2 M8g instances offload CPU virtualization and storage operations to dedicated hardware and software. This approach enhances the overall security posture of your applications and workloads by minimizing the attack surface and improving performance.
Benefits of Using M8g Instances¶
Cost Efficiency¶
One of the standout benefits of the M8g instances is their cost-effective pricing structure. The advanced architecture allows for lower costs while maximizing performance, enabling organizations to save money without compromising on application responsiveness and processing power.
Broad Workload Suitability¶
M8g instances are built for versatility and can efficiently run various workloads. Whether for enterprise applications, machine learning tasks, or even IoT applications, these instances can seamlessly adapt to meet the demands of various scenarios.
Simplified Scaling¶
With M8g instances, organizations can easily scale their workload up or down. The various instance sizes provide the necessary flexibility, enabling companies to dynamically adapt to changes in customer demand.
Application Scenarios for M8g Instances¶
Application Servers¶
M8g instances are suited for managing application servers efficiently, making it perfect for microservices architecture where multiple small services must operate within a single application.
Caching Fleets¶
Caching requires speed and efficient resource use—attributes that M8g instances excel at. They provide rapid access to stored data, dramatically improving application response times.
Gaming Servers¶
The gaming industry demands high-performance environments to deliver smooth and engaging user experiences. M8g instances are ideal for game hosting, capable of handling simultaneous connections and data processing.
Data Stores¶
M8g instances are also robust enough to support midsize data stores, offering the capacity and performance needed for operational databases.
How to Migrate Your Workloads to M8g Instances¶
AWS Graviton Fast Start Program¶
To ease the transition to Graviton-based instances, AWS provides the Graviton Fast Start program. This program is designed to help customers migrate their existing workloads to leverage the power of Graviton processors.
Porting Advisor for Graviton¶
The Porting Advisor for Graviton is a tool that helps developers understand the compatibility of their applications with Graviton instances. This tool offers guidance on necessary changes, recommended best practices, and resources for a successful migration.
Using the AWS Management Console¶
To get started with M8g instances, users can navigate to the AWS Management Console. The intuitive interface allows users to launch new instances quickly, configure settings, and allocate resources tailored to their requirements.
Setting Up Amazon EC2 M8g Instances¶
Step-by-Step Instructions¶
- Access the AWS Management Console: Login to your AWS account and navigate to the EC2 dashboard.
- Launch Instance: Click on the “Launch Instance” button to start configuring a new EC2 instance.
- Choose an Amazon Machine Image (AMI): Select an AMI that suits your workload. Make sure it’s compatible with the Graviton processor.
- Select Instance Type: Choose your new M8g instance type from the list of available instances.
- Configure Instance Details: Set the number of instances, networking options, and any other configurations needed.
