Amazon CloudFront announces price cuts of up to 36% in India and up to 20% in the Asia Pacific region (Hong Kong, Indonesia, Philippines, Singapore, South Korea, Taiwan, & Thailand) for Regional Data Transfer Out to Internet rates. The new CloudFront prices in these regions are effective May 1st, 2021.
要注意的是不同帳號的 a 不一定相同 (像是 us-east-1a 在不同帳號對應到的實際 AZ 不同)，得透過 AWS 提供的資料確認底層實際的 AZ 是哪個。
回朔到這個月月初生效：
Starting May 1st 2021, all data transfer over a VPC Peering connection that stays within an Availability Zone (AZ) is now free. All data transfer over a VPC Peering connection that crosses Availability Zones will continue to be charged at the standard in-region data transfer rates. You can use the Availability Zone-ID to uniquely and consistently identify an Availability Zone across different AWS accounts.
In order to make it easier for AWS Partners and others to gain access to CloudWatch metrics faster and at scale, we are launching CloudWatch Metric Streams. Instead of polling (which can result in 5 to 10 minutes of latency), metrics are delivered to a Kinesis Data Firehose stream.
When you set up a stream you choose between the binary Open Telemetry 0.7 format, and the human-readable JSON format.
另外一個賣點是價位，每千次 $0.003：
Pricing – You pay $0.003 for every 1000 metric updates, and for any charges associated with the Kinesis Data Firehose. To learn more, check out the pricing page.
之前如果要自己拉出來的話是透過 API call 抓，每 1000 次是 USD$0.01，這個方法相較起來便宜不少，不過數量多的時候還是一筆費用 (而且有不少 metrics 是一分鐘更新一次)。
如果只是要備份起來或是跑分析的話，也許先前用 API 拉的作法可能還是比較好？一個小時拉一次對於備份與分析應該都很夠了，而 alarm 的機制還是掛在 CloudWatch 上。
這次產品的定位看起來是要把 ecosystem 做起來：
We designed this feature with the goal of making it easier & more efficient for AWS Partners including Datadog, Dynatrace, New Relic, Splunk, and Sumo Logic to get access to metrics so that the partners can build even better tools.
Built on our new EBS Block Express architecture that takes advantage of some advanced communication protocols implemented as part of the AWS Nitro System, the volumes will give you up to 256K IOPS & 4000 MBps of throughput and a maximum volume size of 64 TiB, all with sub-millisecond, low-variance I/O latency. Throughput scales proportionally at 0.256 MB/second per provisioned IOPS, up to a maximum of 4000 MBps per volume. You can provision 1000 IOPS per GiB of storage, twice as many as before. The increased volume size & higher throughput means that you will no longer need to stripe multiple EBS volumes together, reducing complexity and management overhead.
The preview is currently available in the US East (N. Virginia), US East (Ohio), US West (Oregon), Asia Pacific (Singapore), Asia Pacific (Tokyo), and Europe (Frankfurt) Regions. During the preview, we support the use of R5b instances, with support for other Nitro-powered instances in the works.
Now, with the new tiered pricing structure, the first 32,000 IOPS provisioned on a volume are charged at the current base rate ($0.065 per provisioned IOPS-mo) and the second tier between 32,001 and 64,000 is charged at a 30% lower rate ($0.046 per provisioned IOPS-mo).
Furthermore, for customers who have even higher performance requirement than currently supported by a single io2 volume today, we are previewing io2 volumes that run on EBS Block Express, the next generation of our block storage architecture. io2 Block Express volumes can be provisioned to deliver peak IOPS of 256,000. For these volume, any IOPS provisioned over 64,000 IOPS will be charged at a further 30% lower rate than the second tier ($0.032 per provisioned IOP-mo for IOPS over 64,000). This lowers the effective rate to $0.038 per provisioned IOPS on a volume provisioned with 256,000 IOPS.
Today I would like to tell you about gp3, a new type of SSD EBS volume that lets you provision performance independent of storage capacity, and offers a 20% lower price than existing gp2 volume types.
然後直接給你 3000 IOPS 與 125MB/sec，有需要更高的話可以「加購」：
gp3 is designed to provide predictable 3,000 IOPS baseline performance and 125 MiB/s regardless of volume size. It is ideal for applications that require high performance at a low cost such as MySQL, Cassandra, virtual desktops and Hadoop analytics. Customers looking for higher performance can scale up to 16,000 IOPS and 1,000 MiB/s for an additional fee. The top performance of gp3 is 4 times faster than max throughput of gp2 volumes.
If you’re currently using gp2, you can easily migrate your EBS volumes to gp3 using Amazon EBS Elastic Volumes, an existing feature of Amazon EBS. Elastic Volumes allows you to modify the volume type, IOPS, and throughput of your existing EBS volumes without interrupting your Amazon EC2 instances.
