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
||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 instances are available today in On-Demand, Reserved, and Spot form.
