With just 12 ms of round-trip latency between US East (Ohio) and US East (Northern Virginia), you can make good use of unique AWS features such as S3 Cross-Region Replication, Cross-Region Read Replicas for Amazon Aurora, Cross-Region Read Replicas for MySQL, and Cross-Region Read Replicas for PostgreSQL.
其中有個特別的地方在於 us-east-{1,2} 之間傳輸的費用會以 Inter-AZ 計費，而非以跨 region 計費。大概是希望讓大家有動力多放些東西過去，畢竟 us-east-1 實在太大，穩定性超有名的關係 XDDD：
Data transfer between the two Regions is priced at the Inter-AZ price ($0.01 per GB), making your cross-region use cases even more economical.
Regarding the second flight scenario, 20 runs were performed in the engineering simulator from a preprogrammed point shortly before the loss of engine thrust in which pilots attempted to return to either runway 13 or 22 at LGA or runway 19 at TEB. Five of the 20 runs were discarded because of poor data or simulator malfunctions. Of the 15 remaining runs, in 6, the pilot attempted to land on runway 22 at LGA; in 7, the pilot attempted to land on runway 13 at LGA; and in 2, the pilot attempted to land on runway 19 at TEB. In eight of the 15 runs (53 percent), the pilot successfully landed after making an immediate turn to an airport after the loss of engine thrust. Specifically, two of the six runs to land on runway 22 at LGA, five of the seven runs to land on runway 13 at LGA, and one of the two runs to land on runway 19 at TEB immediately after the loss of engine thrust were successful. One run was made to return to an airport (runway 13 at LGA) after a 35-second delay, and the landing was not successful.
These orders are so highly classified that simply acknowledging an order's existence is illegal, even a company's chief executive or members of the board may not be told. Only those who are necessary to execute the order would know, and would be subject to the same secrecy provisions.
In just a matter of days, U.S. airlines will begin a fierce bidding war to win routes and airport slots to a destination that's been off-limits to them for more than 50 years: Cuba.
不過這次還是沒有開放古巴的飛機：
CNN is told there are no plans in the near future for Cuban-owned planes to land in the U.S. under this agreement.
