AWS high memory instance type : Good for Oracle Databases on AWS

The r3.8xlarage has 244 GiB of memory, 32 vCPUs, and 2 - 320 GB SSD drives. The cost is $2.80 per hour for on-demand instances.  More details here:

Prior to this you had to use the i2.8xlarge instance type which also has 244 GiB of memory and 32 vCPUs. But also has 8 - 800 GB SSD drives which you will most likely not use for your Oracle Database.  The cost of i2.8xlage is $6.82 per hour for on-demand instances.  The other highest memory option is the cr1.8xlarge with 32 vCPUs and 244 GIB with 2 -120 GB SSD drives.  The cost of this option is $3.50 per hour for on-demand instances.
The R3 instances include the following features:
  • Intel Xeon E5-2670 v2 "Ivy Bridge" Processors
  • Hardware Virtualization (HVM) only
  • SSD-backed instance storage, including TRIM support
  • Enhanced Networking with lower latency, low jitter, and high packet-per-second performance

One caveat here that Oracle has not released any HVM-based instance types.  There are undocumented methods to create an HVM AMI from a PVM AMI but this new AMI may not be supported by Oracle.

  1. Tom, we don't see the Oracle AMI's (at least 11.2) will let you launch an R3 type instance, is there a way to make it work? Maybe snapshot virgin volumes of the AMI? (But I don't see a way to launch oracle enterprise linux on a r3.* anything??)

  2. Ryan,
    I just updated the post. There is a caveat with using R3 with the available Oracle AMIs.
