AWS Launches Massive X1 Instances Targeting High Memory Workloads @ InfoQ
"AWS recently added a new instance type with nearly 2 terabytes of memory and 128 virtual CPUs. This is the largest virtual server available today in the public cloud, and is a target for memory-intensive workloads such as SAP HANA.
The instance specifications are:
  • 128 vCPU via four Intel Xeon E7-8880 v3 processors
  • 1,952 GiB of DDR4-based RAM
  • 3.84 TB of local SSD storage, capable of up to 126,000 random-read IOPS
  • 10Gbps of network bandwidth"
The x1 starts at $13.338 per hour for an on-demand instance. Customers can get that down to $3.732 per hour with a three year commitment (“reserved instance”), and a $98,072 upfront payment
