Today, we are excited to announce that, due to high customer demand for additional services in Osaka, the Osaka Local Region will be expanded into a full AWS Region with three Availability Zones by early 2021.
Today we are launching a preview (sign up now) of Amazon Aurora Serverless. Designed for workloads that are highly variable and subject to rapid change, this new configuration allows you to pay for the database resources you use, on a second-by-second basis.
然後是極為快速的 auto-scaling:
The endpoint is a simple proxy that routes your queries to a rapidly scaled fleet of database resources. This allows your connections to remain intact even as scaling operations take place behind the scenes. Scaling is rapid, with new resources coming online within 5 seconds
Amazon Aurora Multi-Master allows you to create multiple read/write master instances across multiple Availability Zones. This enables applications to read and write data to multiple database instances in a cluster, just as you can read across Read Replicas today.
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.
