The new “Medium” instance isn’t as powerful as the service’s Large instances, but it’s cheaper, and it’s more powerful than the low-end Small instances. But perhaps the bigger news within the news here, however, is that all instances now support 64-bit OSes, which was previously reserved for the highest tiers only. Amazon said it has also integrated the MindTerm SSH client into the AWS Management console 'to simplify the process of connecting to an EC2 instance.' What’s the bigger news here: 64-bit across the board or the sweet-spotting of tiers?"
