X1 instances extend the
elasticity, simplicity, and cost savings of the AWS cloud to
enterprise-grade applications with large dataset requirements. X1
instances are ideal for running in-memory databases like SAP HANA, big
data processing engines like Apache Spark or Presto, and high
performance computing (HPC) applications. X1 instances are certified by
SAP to run production environments of the next-generation Business Suite
S/4HANA, Business Suite on HANA (SoH), Business Warehouse on HANA (BW),
and Data Mart Solutions on HANA on the AWS cloud.
X1 instances offer 2 TB of DDR4 based memory, 8x the memory
offered by any other Amazon EC2 instance. Each X1 instance is powered
by four Intel® Xeon® E7 8880 v3 (Haswell) processors and offers 128
vCPUs. In addition, X1 instances offer 10 Gbps of dedicated bandwidth to
Amazon Elastic Block Store (Amazon EBS) and are EBS-optimized by default at no additional cost.
