Data Transfer IN To Amazon EC2 From Internet
All data transfer in $0.00 per GB
但從 AZ 進到另外一個 AZ 時，in 與 out 都要收費：
Data transferred "in" to and "out" from Amazon EC2, Amazon RDS, Amazon Redshift, Amazon DynamoDB Accelerator (DAX), and Amazon ElastiCache instances, Elastic Network Interfaces or VPC Peering connections across Availability Zones in the same AWS Region is charged at $0.01/GB in each direction.
所以直接用 US$0.01/GB 的計算是不夠的，得用 US$0.02/GB 來計算。
同樣的，如果是 Public IP 與 Elastic IP 也都是雙向收費，跨 VPC 也是雙向收費，所以都要用 US$0.02/GB 來算：
IPv4: Data transferred “in” to and “out” from public or Elastic IPv4 address is charged at $0.01/GB in each direction.
IPv6: Data transferred “in” to and “out” from an IPv6 address in a different VPC is charged at $0.01/GB in each direction.
We decided to start charging for Kagi search while in beta status because the cost of beta usage has gone up dramatically and we are not able to sustain it. Also, we want to get some kind of a financial “airworthiness” signal and see how we stand with our positioning and outlook for sustainability.
With this launch, the default message size limit in Amazon SES V2 increases from 10MB for email sending and 30MB for email receiving, to 40MB for both sending and receiving .
The Deliverability Dashboard (via the SES API V2) is available for a fixed price of USD $1,250 per month. This charge includes reputation monitoring for up to five domains and 25 predictive email placement tests.
一般性的 data transfer 從 1GB/month/region 變成 100GB/mo，現在是 21 regions 所以不會有反例，另外大多數的人或是團隊也就固定用一兩個 region，這個 free tier 大概可以省個 $10 到 $20 左右？
Data Transfer from AWS Regions to the Internet is now free for up to 100 GB of data per month (up from 1 GB per region). This includes Amazon EC2, Amazon S3, Elastic Load Balancing, and so forth. The expansion does not apply to the AWS GovCloud or AWS China Regions.
Data Transfer from Amazon CloudFront is now free for up to 1 TB of data per month (up from 50 GB), and is no longer limited to the first 12 months after signup. We are also raising the number of free HTTP and HTTPS requests from 2,000,000 to 10,000,000, and removing the 12 month limit on the 2,000,000 free CloudFront Function invocations per month. The expansion does not apply to data transfer from CloudFront PoPs in China.
今年十二月才生效，要注意一下不要現在就用爽爽：
This change is effective December 1, 2021 and takes effect with no effort on your part.
這樣好像可以考慮把 blog 與 wiki 都放上去玩玩看，目前這兩個服務都是用 Cloudflare 的 free tier，HiNet 用戶基本上都是連去 Cloudflare 的美西 PoP，偶而離峰時間會用亞洲的點，但都不會是台灣的 PoP...
我找了一下到底是什麼地區，目前只有看到「Wasabi Technologies Inc Status」這邊有編號 (US-East-1、US-East-2、US-Central-1、US-West-1、EU-Central-1、AP-Northeast-1)，但也沒找到地區... US 的都在美國沒問題，AP-Northeast-1 應該是日本，但 EU-Central-1 是哪裡就找不到了。
另外是 pay-as-you-go 的方案最小是 1TB，如果是歐美區的話是 US$5.99：
For customers using the Wasabi pay-as-you-go pricing model, Wasabi has a minimum monthly charge associated with 1 TB of active storage. If you store less than 1 TB of active storage in your account, you will still be charged for 1 TB of storage based on the pricing associated with the storage region you are using.
然後也有 90 天的最短計價時間：
Wasabi has a minimum storage duration policy that means if stored objects are deleted before they have been stored with Wasabi for a certain number of days (90 days when using the Wasabi pay-go pricing model), a Timed Deleted Storage charge equal to the storage charge for the remaining days will apply.
80. We split each file into 80 different encrypted pieces, and each piece is stored on a different Node.
When you retrieve an object, only 29 of its 80 pieces are needed to reconstitute that object. With no central point of failure, your data is always quickly available, all over the world.
R2 builds on Cloudflare’s commitment to the Bandwidth Alliance, providing zero-cost egress for stored objects — no matter your request rate. Egress bandwidth is often the largest charge for developers utilizing object storage and is also the hardest charge to predict. Eliminating it is a huge win for open-access to data stored in the cloud.
That doesn’t mean we are shifting bandwidth costs elsewhere. Cloudflare R2 will be priced at $0.015 per GB of data stored per month — significantly cheaper than major incumbent providers.
在 durability 的部份，與 S3 都是一年 11 個 9：
The core of what makes Object Storage great is reliability — we designed R2 for data durability and resilience at its core. R2 will provide 99.999999999% (eleven 9’s) of annual durability, which describes the likelihood of data loss.
目前還沒有公開，算是先對市場放話：
R2 is currently under development — you can sign up here to join the waitlist for access.
Cloudflare Images offers multiple ways to upload your images. We accept all the common file formats including JPEG, GIF and WEBP. Each image uploaded to Images can be up to 10 MB.
