AWS announces unlimited network burst duration on EC2 I8g and I7i instances

AWS QuickSight Release Notes

AWS has eliminated the networking bandwidth burst duration limitations for Amazon EC2 I7i and I8g instances on sizes larger than 4xlarge. This update doubles the Network Bandwidth available at all times for i7i and i8g instances on sizes larger than 4xlarge. Previously, these instance sizes had a baseline bandwidth and used a network I/O credit mechanism to burst beyond their baseline bandwidth on a best effort basis. Today these instance sizes can sustain their maximum performance indefinitely. With this improvement, customers running memory and network intensive workloads on larger instance sizes can now consistently maintain their maximum network bandwidth without interruption, delivering more predictable performance for applications that require sustained high-throughput network connectivity.

Amazon EC2 I7i and I8g instances are designed for I/O intensive workloads that require rapid data access and real-time latency from storage. These instances excel at handling transactional, real-time, distributed databases, including MySQL, PostgreSQL, Hbase and NoSQL solutions like Aerospike, MongoDB, ClickHouse, and Apache Druid. They're also optimized for real-time analytics platforms such as Apache Spark, data lakehouse, and AI LLM pre-processing for training. These instances have up to 1.5 TiB of memory, and 45 TB local instance storage. They deliver up to 100 Gbps of network performance bandwidth, and 60 Gbps of dedicated bandwidth for Amazon Elastic Block Store (EBS).

What to do

• Review the new capabilities of I7i and I8g instances.
• Update your applications to take advantage of the new sustained bandwidth.
• Monitor performance improvements in your workloads.
