The high frequency z1d instances use custom Intel® Xeon® Scalable Processors running at up to 4.0 GHz, powered by sustained all-core Turbo Boost, perfect for Electronic Design Automation (EDA), financial simulation, relational database, and gaming workloads that can benefit from extremely high per-core performance.
Brad Fitzpatrick 在他家裡弄的 HA 架構，對一般人來說是有點誇張了 (看起來主要還是玩得開心)，但對網路公司來說是個可以參考的方式，降低網路與設備故障帶來的業務衝擊... 先前在弄辦公室連外網路時也有弄過類似的架構，還蠻有趣的。
The whole setup including all APs and switches draws about 220 watts idle. Power is pretty cheap in Seattle. Washington State (as of April 2018) has the cheapest electricity in the United States, at $0.0974/kWh.
M5d instances are available in On-Demand, Reserved Instance, and Spot form in the US East (N. Virginia), US West (Oregon), EU (Ireland), US East (Ohio), and Canada (Central) Regions. Prices vary by Region, and are just a bit higher than for the equivalent M5 instances.
The introduction of the processor instructions AES-NI and VPCLMULQDQ, that are designed for speeding up encryption, and their continual performance improvements through processor generations, has significantly reduced the costs of encryption overheads.
More and more applications and platforms encrypt all of their data and traffic. As an example, we note the world wide proliferation of the use of AES-GCM, with performance dropping down to 0.64 cycles per byte (from ~23 before the instructions), on the latest Intel processors.
