Starting today, Amazon EC2 M8i and M8i-flex instances are now available in Canada West (Calgary) region. These instances are powered by custom Intel Xeon 6 processors, available only on AWS, delivering the highest performance and fastest memory bandwidth among comparable Intel processors in the cloud. The M8i and M8i-flex instances offer up to 15% better price-performance, and 2.5x more memory bandwidth compared to previous generation Intel-based instances. They deliver up to 20% better performance than M7i and M7i-flex instances, with even higher gains for specific workloads. The M8i and M8i-flex instances are up to 30% faster for PostgreSQL databases, up to 60% faster for NGINX web applications, and up to 40% faster for AI deep learning recommendation models compared to M7i and M7i-flex instances.  
  
M8i-flex instances are the easiest way to get price performance benefits for a majority of general-purpose workloads like web and application servers, microservices, small and medium data stores, virtual desktops, and enterprise applications. They offer the most common sizes, from large to 16xlarge, and are a great first choice for applications that don't fully utilize all compute resources.  
  
M8i instances are a great choice for all general-purpose workloads, especially for workloads that need the largest instance sizes or continuous high CPU usage. The SAP-certified M8i instances offer 13 sizes including 2 bare metal sizes and the new 96xlarge size for the largest applications.  
  
To get started, sign in to the [AWS Management Console](https://aws.amazon.com/console/). For more information about the new instances, visit the [M8i and M8i-flex instance page](https://aws.amazon.com/ec2/instance-types/m8i/) or visit the AWS News [blog](https://aws.amazon.com/blogs/aws/new-general-purpose-amazon-ec2-m8i-and-m8i-flex-instances-are-now-available/).
