December 20, 2013 at 17:45AWS has announced new instances. Now up to 32 cores, 244GB RAM, 8x800 GB SSD
I just got the announcement that the new generation of Amazon EC2 High I / O has become available on AWS. These types of instances are based on the new generation of Intel Ivy Bridge processors. Each virtual CPU (vCPU) corresponds to one hardware hyperthread thread of the Intel Xeon processor E5-2670 v2 (Ivy Bridge).
Here is the plate:
These instance types provide the largest number of IOPs (I / O operations per second) compared to other existing types. For example, i2.8xlarge provides more than 365,000 random read operations of 4 kilobyte blocks and more than 315,000 random read operations of 4 kilobyte blocks.
AWS recommends type I2 instances for high-performance NoSQL DBMSs such as Cassandra and MongoDB.
Here is the plate:
| Instance type | vCPUs | ECU Rating | Memory (GiB) | Instance Storage SSD (GB) | Linux On-Demand Price * ($ / hr) |
| i2.xlarge | 4 | 14 | 30.5 | 1x800 | $ 0.85 |
| i2.2xlarge | 8 | 27 | 61 | 2x800 | $ 1.71 |
| i2.4xlarge | 16 | 53 | 122 | 4x800 | $ 3.41 |
| i2.8xlarge | 32 | 104 | 244 | 8x800 | $ 6.82 |
