EC2’s R3 instances are designed to provide you with the best price per GiB of RAM, along with high memory performance. I am happy to be able to announce that they are now available in the South America (Brazil) region, in two sizes.
Here are the specs:
Instance Name | vCPU Count |
RAM |
SSD Storage | Hourly On-Demand (Linux) |
RI All UpFront (Linux, 3 Year) |
RI Price / Hour (Linux, 3 Year) |
r3.4xlarge | 16 | 122 GiB | 1 x 320 | $2.946 | $17,345 | $0.660 |
r3.8xlarge | 32 | 244 GiB | 2 x 320 | $5.892 | $34,690 | $1.320 |
Here are some of the other notable features and characteristics of these instances:
- Intel Xeon (Ivy Bridge) processors.
- Support for Enhanced Networking for lower latency, low jitter, and high packet per second performance.
- Sustained memory bandwidth of up to 63 GBps.
- Fast I/O performance – up to 150,000 4 KB random reads per second.
You can use these instances for in-memory analytics (SAP HANA springs to mind), high performance relational and NoSQL databases, data warehouses, and memory-resident caches.
The r3.4xlarge instances can also be launched in EBS-Optimized form. Both instances support Hardware Virtualization (HVM) AMIs only; see the R3 Technical Documentation for more information.
The instances are available today in On-Demand, Reserved, and Spot form.
