Amazon introduces two news instance types for CPU intensive applications
Amazon has introduced today two new instance types targeted for CPU intensive applications which do not require the amount of memory made available to the large and extra large instances.
The High-CPU Medium instance type provides 5 EC2 Compute Units (2 virtual cores with 2.5 EC2 Compute Units each), 1.7 GB of memory, 350 GB instance storage (340 GB plus 10 GB root partition) and a Moderate I/O (like the Small instance type). This instance is a great way to move from a Small instance to a more CPU powered one because this instance type still is a 32 bit system. This instance type is priced at $.20 per CPU/hour.
The High-CPU Extra Large instance type provides 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each), 7 GB of memory, 1,690 GB instance storage (4 x 420 GB plus 10 GB root partition) and a High I/O (like the Large and Extra-Large instance types). This instance type is priced at $.80 per CPU/hour.
Those two new instance types provides now more options regarding on what you want to scale, that is I/O, CPU or Memory.
