Very intresting article about EC2 enviroment
Ever wonder what hardware is running behind Amazon’s EC2? Why would you even care? Well, there are at least a couple of reasons.
- Side-by-side comparisons. Amazon express their machine power in terms of EC2 compute units (ECU) and other cloud providers just express it in terms of number of cores. Either case, it is vague and you cannot perform economical comparison between different cloud offerings, and with owning-your-own-hardware approach. Knowing how much a EC2 computing unit is in terms of hardware raw power allows you to perform apple-to-apple comparison.
- Physical isolation. In many enterprise clients’ mind, security is the number one concern. Even though hypervisor isolation is robust, they feel more comfortable if there is a physical separation, i.e., they do not want their VM to sit on the same physical hardware right next to a hacker’s VM. Knowing the hardware computing power and the largest VM’s computing…
