It's amazing to recall that it was even possible to virtualize x86 before processors had hardware-assisted virtualization (Intel VT-x and AMD-V), which were added in 2005 and 2006. But not all workloads: some are network bound (proxies) and storage bound (databases). ## 5. The AMI and boot are now HVM.

At the instance level, many CPU and system architectures have direct access to power consumption metrics. Clock rates also change, some ARM architectures include a mixture of high performance and low power cores in the same CPU, and Intel architecture CPUs have hyperthreading, so the performance of an execution thread will vary over time.

The epoch of AWS is the launch of Amazon S3 on March 14, 2006, now almost 10 years ago. The expectation was that with each order or two of magnitude, we would need to revisit and revise the architecture to make sure we could address the issues of scale.
