You can now run Microsoft Windows Server 2008 R2 on the EC2 Cluster Compute and Cluster GPU instances using new Windows 2008 R2 and Windows 2008 R2 SQL Server AMIs.
To reiterate, here are the specs for these compute-intensive instance types:
Cluster Compute Quadruple Extra Large:
- 23 GB of memory
- 33.5 EC2 Compute Units (2 x Intel Xeon X5570, quad-core “Nehalem” architecture)
- 1690 GB of instance storage
- 64-bit platform
- I/O Performance: Very High (10 Gigabit Ethernet)
Cluster GPU Quadruple Extra Large:
- 22 GB of memory
- 33.5 EC2 Compute Units (2 x Intel Xeon X5570, quad-core “Nehalem” architecture)
- 2 x NVIDIA Tesla “Fermi” M2050 GPUs
- 1690 GB of instance storage
- 64-bit platform
- I/O Performance: Very High (10 Gigabit Ethernet)
These instances provide you with plenty of RAM, cycles, and network performance for heavy-duty workloads. With this release, you can now run Microsoft Windows on every one of the eleven EC2 instance types, from the Micro on up.
You can select the Windows Server 2008 R2 AMI for Cluster Instances from the AWS Management Console:
