Amazon EC2 I8g Instances

Best performance in Amazon EC2 for storage-intensive workloads

Why Amazon EC2 I8g Instances?

Amazon Elastic Compute Cloud (EC2) I8g and I8ge instances are next-generation, AWS Graviton4-powered storage optimized instances designed to run applications that require high throughput and real-time latency access to data on local SSD storage. These instances use 3rd generation AWS Nitro SSDs. AWS Nitro SSDs are custom built by AWS and offer performance at cloud scale and security with always-on encryption. I8g instances provide up to 45 TB while I8ge instances provide up to 120 TB of local NVMe storage.

I8g instances are optimized for I/O intensive workloads that require real-time latency access to data such as relational databases (MySQL, and PostgreSQL), real-time databases, NoSQL databases (Aerospike, Apache Druid, Clickhouse, MongoDB), and real-time analytics such as Apache Spark. I8ge instances are optimized for workloads similar to those of I8g instances, but for workloads that require much larger storage density. I8g instances deliver the best compute performance among storage-optimized Amazon EC2 instances. I8ge instances deliver the highest storage density among AWS Graviton-based storage optimized instances and the highest networking bandwidth among storage optimized  Amazon EC2 instances.

Benefits

I8g and I8ge instances are based on 3rd generation AWS Nitro SSD, and they offer up to 45 TB and 120 TB of instance storage respectively. At 120 TB of instance storage, I8ge instances have the highest storage density among Graviton-based storage optimized instances. I8g instances provide up to 65% higher real-time storage performance per TB, 50% lower storage I/O latency, and 60% lower storage I/O latency variability compared to previous generation Graviton-based storage optimized I4g instances. I8ge instances provide up to 55% higher real-time storage performance per TB, 60% lower storage I/O latency, and 75% lower storage I/O latency variability compared to previous generation Graviton-based storage optimized Im4gn instances.

I8g and I8ge instances deliver up to 60% better compute performance compared to their respective previous generation Graviton-based storage optimized instances. These instances include DDR5-5600 memory and are ideal for I/O intensive workloads, such as real-time databases and real-time analytics.

AWS Graviton-based instances are supported by the most popular Linux operating systems. Popular applications and services for security, monitoring and management, containers, and continuous integration and delivery (CI/CD) from AWS and partners support Graviton based instances. Customers can also find certified solutions for Graviton using the AWS Graviton Ready program.

Features

AWS Graviton4 is the latest generation of server processors designed by AWS that provide the best performance and energy efficiency for workloads in Amazon EC2. AWS Graviton4 processors deliver up to 30% better compute performance than Graviton3 processors and 60% better compute performance than Graviton2 processors.

AWS Graviton4 processors offer enhanced security with always-on memory encryption, dedicated cache for every vCPU, and support for pointer authentication. I8g and I8ge instances also support encrypted Amazon Elastic Block Store.

The AWS Nitro System is a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware and software. It delivers high performance, high availability, and high security, reducing virtualization overhead.

Meltwater

Meltwater's main Elasticsearch cluster indexes billions of new documents and serves millions of search requests every day to help our customers track conversations as they happen. Storage optimized Amazon EC2 I8ge instances represent the single biggest performance boost across search, indexing, and analytics that we have seen in the last decade — more than a 2x performance compared to Amazon EC2 I3en instances. Switching to AWS Graviton4 enables our customers to enjoy an even snappier search experience and allows us to further increase the freshness and breadth of data available for instant analysis. We are equally excited about the potential for accelerating our vector search applications by switching from Amazon EC2 M7gd instances to Amazon EC2 I8g instances, especially for our multi-turn agent elastic cluster.

Bright Data

By migrating to AWS Graviton4-based Amazon EC2 instances, we have transformed our operational performance. For example, after upgrading to Amazon EC2 I8g instances, we see 133% better performance in the MongoDB database tasked with 1 billion daily record updates. A critical server infrastructure that manages more than 300,000 concurrent websocket connections experienced similar gains: a 66% performance improvement after transitioning from Amazon EC2 M6g instances to Amazon EC2 M8g instances. These enhancements have not only reduced our infrastructure costs but also enabled us to deliver faster, more reliable data services to our clients, strengthening our position as the world's leading web data platform.
