Starting today, Amazon EC2 Is4gen and Im4gn instances, the latest generation storage-optimized instances, are available in the AWS Asia Pacific (Sydney), Canada (Central), Europe (Frankfurt), Europe (London) Regions. Is4gen and Im4gn instances are built on the AWS Nitro System and are powered by AWS Graviton2 processors. They feature up to 30TB of storage with the new AWS Nitro SSDs that are custom-designed by AWS to maximize the storage performance of I/O intensive workloads such as SQL/NoSQL databases, search engines, distributed file systems and data analytics which continuously read and write from the SSDs in a sustained manner. AWS Nitro SSDs enable up to 60% lower latency and up to 75% reduced latency variability in Im4gn and Is4gen instances compared to the third generation of storage optimized instances. These instances maximize the number of transactions processed per second (TPS) for I/O intensive workloads such as relational databases (e.g. MySQL, MariaDB, PostgreSQL), and NoSQL databases (KeyDB, ScyllaDB, Cassandra) which have medium-large size data sets and can benefit from high compute performance and high network throughput. They are also an ideal fit for search engines, and data analytics workloads that require very fast access to data sets on local storage.
The Im4gn instances provide the best price performance for storage-intensive workloads in Amazon EC2. They offer up to 40% better price performance and up to 44% lower cost per TB of storage compared to I3 instances for running applications such as MySQL, NoSQL, and file systems, which require dense local SSD storage and higher compute performance. They also feature up to 100 Gbps networking and support for Elastic Fabric Adapter (EFA) for applications that require high levels of inter-node communication.
The Is4gen instances provide the lowest cost per TB and highest density per vCPU of SSD storage in Amazon EC2 for applications such as stream processing and monitoring, real-time databases, and log analytics, that require high random I/O access to large amounts of local SSD data. These instances enable 15% lower cost per TB of storage and up to 48% better compute performance compared to I3en instances.
With this regional expansion, Im4gn and Is4gen instances are now available in the following AWS regions: US East (Ohio), US East (N. Virginia), US West (Oregon), Canada (Central), Europe (Ireland), Europe (Frankfurt), Asia Pacific (Sydney) and Europe (London) Regions and are purchasable On-Demand, as Reserved instances, as Spot instances, or as part of Savings Plans. Im4gn is available in 6 sizes providing up to 64 vCPUs, 30 TB SSD storage, 256 GB memory, 100 Gbps of networking bandwidth, and 38 Gbps of Amazon Elastic Block Store (Amazon EBS) bandwidth. The Is4gen instances will be available soon in 6 sizes providing up to 32 vCPUs, 30 TB SSD storage, 192 GB memory, 50 Gbps of networking bandwidth, and 19 Gbps of Amazon EBS bandwidth.
