AWS 大阪區

在寫前一篇「Inter-Region VPC Peering 的範圍大幅增加」時,跑去查了資料「AWS Regions and Endpoints」,發現 AWS 增加了 ap-northeast-3,但不同於其他區域的標法,大阪區的 Region Name 是「Asia Pacific (Osaka-Local)」,那個 Local 不知道代表什麼 XD

另外透過搜尋翻到的,在 Twitter 上的 AWS 日本帳號也提到了大阪區的消息:

Inter-Region VPC Peering 的範圍大幅增加

AWS 的 Inter-Region VPC Peering 又多了不少區域了:「Inter-Region VPC Peering is Now Available in Nine Additional AWS Regions」。

本來是支援 us-{east,west}-{1,2} 這四個,現在又多了 9 個,來到了 13 個:

Starting today, Inter-Region Virtual Private Cloud (VPC) Peering is available in AWS EU (London), EU (Ireland), EU (Paris), Asia Pacific (Mumbai), Asia Pacific (Sydney), Asia Pacific (Singapore), Asia Pacific (Tokyo), Canada (Central) and South America (São Paulo) Regions in addition to AWS US East (Northern Virgina), US East (Ohio), US West (Northern California), US West (Oregon) Regions.

與現在的 region 表格比較,剩下的是 ap-northeast-2 (南韓首爾) 與 eu-central-1 (德國法蘭克福),其他公開使用的區域都在這波的公告全上了。(也就是美國政府專屬區域與中國區不算在內)

NAVER CLOUD PLATFORM

在「HashiCorp Packer 1.2.0」這篇看到的雲端平台:

New builder: ncloud for building server images using the NAVER Cloud Platform.

NAVERLine 母公司,這是他們推出的雲端平台,看起來相似的產品是 AWS。在 https://www.ncloud.com/charge/region 這邊可以看到提供了韓國、美國、新加坡、香港、日本與德國,可以看出因為是韓國公司,擴了不少亞洲的點...

找時間看一看好了,目前看起來 routing 好像還不錯?

DynamoDB 可以透過 KMS 加密了...

AWSDynamoDB 可以透過 KMS 加密了:「New – Encryption at Rest for DynamoDB」。

You simply enable encryption when you create a new table and DynamoDB takes care of the rest. Your data (tables, local secondary indexes, and global secondary indexes) will be encrypted using AES-256 and a service-default AWS Key Management Service (KMS) key.

看起來不是自己的 KMS key,而是 service 本身提供的,這樣看起來是在 i/o level 加密,所以還不是 searchable encryption 的能力...

AWS Tokyo 也有 Amazon Aurora (PostgreSQL) 可以用了

剛剛翻到 AWS 宣佈 Amazon Aurora (PostgreSQL) 在東京開放使用了:「Amazon Aurora with PostgreSQL Compatibility is Available in the Asia Pacific (Tokyo) Region」。

The PostgreSQL-compatible edition of Amazon Aurora is now available in 10 regions. With the addition of the AWS Asia Pacific (Tokyo) region, you have a new option for database placement, availability, and scalability.

不過 Region Table 裡面還沒更新,亞洲區裡面的東京還沒勾起來,應該過幾天就會更新了...

AWS 公開了在台北的 Direct Connect 接口

也是個很久前就聽到傳言的消息... AWS 剛剛公佈了在台北的 Direct Connect 接口,用戶可以在台北內租用線路進機房就連上 Direct Connect:「New AWS Direct Connect sites land in Paris and Taipei」。

AWS Direct Connect also launched its first site in Taiwan at Chief Telecom LY, Taipei. In the Management Console, Taipei is located in the Asia Pacific (Tokyo) Region. With global access enabled for AWS Direct Connect, these sites can reach AWS resources in any global AWS region using global public VIFs and Direct Connect Gateway.

以往需要透過像 GCX 這樣的公司租用國際頻寬,再從 GCX 在台北的機房拉到自家機房 (通常是市內專線),現在只需要在台北對接的這段就可以了。

台北的接點在 AWS 上寫的是 Chief Telecom LY, Taipei, Taiwan,查了一下是是方電訊的「是方麗源大樓 (台北市內湖區陽光街250號)」,也就是之前有發生過火災而大斷線的那棟。對接的 AWS Home Region 是 Asia Pacific (Tokyo),所以使用 ap-northeast-1 的人可以規劃...

AWS 推出 AWS Instance Scheduler,定時幫你開關機的服務...

第一眼在「Introducing the AWS Instance Scheduler」看到「AWS Instance Scheduler」的描述時,跟之前推出的 Scheduled Reserved Instances 搞混...

The AWS Instance Scheduler is a solution that enables customers to easily configure custom start and stop schedules for their Amazon EC2 and Amazon RDS instances. The solution is easy to deploy and can help reduce operational costs for both development and production environments. Customers who use this solution to run instances during regular business hours can save up to 70% compared to running those instances 24 hours a day.

以這張圖來說就更清楚,AWS Instance Scheduler 就是指定時間,定時幫你開關機的服務:

而我搞混的 Scheduled Reserved Instances 是買某個時段的 RI,是作帳議題。不過兩個看起來就很適合搭在一起用...

Amazon Route 53 的 Auto Naming API 可以指到 CNAME 位置了

Amazon Route 53 的 Auto Naming API 可以拿來跑 Service Discovery (參考先前的「用 Amazon Route 53 做 Service Discovery」這篇),當時是 A/AAAA/SRV record,現在則可以註冊 CNAME 了:「Amazon Route 53 Auto Naming Announces Support for CNAME Record Type and Alias to ELB」。

最直接的影響就是 ELB 的部份了,透過 ELB 處理前端的話,覆載平衡以及數量限制的問題就會減輕很多 (之前是靠 Round-robin DNS 打散,而且限制一次最多回應五個 record):

Beginning today, you can use the Amazon Route 53 Auto Naming APIs to create CNAME records when you register instances of your microservices, and your microservices can discover the CNAMEs by querying DNS for the service name. Additionally, you can use the Amazon Route 53 Auto Naming APIs to create Route 53 alias records that route traffic to Amazon Elastic Load Balancers (ELBs).
