用 Amazon Route 53 做 Service Discovery

Amazon Route 53 的新功能,可以解決以前自己要建立 Service Discovery 服務的工作:「Amazon Route 53 Releases Auto Naming API for Service Name Management and Discovery」。官方的文件在「Using Autonaming for Service Discovery」這邊。

不過目前有些限制,一個 namespace (domain name) 目前只能有五個服務:

DNS settings for up to five records.

然後 DNS 回應時,最多回五個 record:

When Amazon Route 53 receives a DNS query for the name of an instance, such as backend.example.com, it responds with up to eight IP addresses (for A or AAAA records) or up to eight SRV record values.

回應八個 record,但應該是可以註冊超過八個吧... (i.e. 每次都回不一樣)

自建服務 (像是 Cassandra 或是 ScyllaDB) 可以直接用這個服務掛上去,就不用自己架 Consul 了。

目前支援了這四區,亞洲不在這波提供範圍:

Amazon Route 53 Auto Naming is available in US East (N. Virginia), US East (Ohio), US West (Oregon), and EU (Ireland) regions.

AWS PrivateLink

AWS 計畫把先前設計的 VPC Endpoint 都併到 AWS PrivateLink 裡,統一管理:「New – AWS PrivateLink for AWS Services: Kinesis, Service Catalog, EC2 Systems Manager, Amazon EC2 APIs, and ELB APIs in your VPC」。

Today we are announcing AWS PrivateLink, the newest generation of VPC Endpoints which is designed for customers to access AWS services in a highly available and scalable manner, while keeping all the traffic within the AWS network. Kinesis, Service Catalog, Amazon EC2, EC2 Systems Manager (SSM), and Elastic Load Balancing (ELB) APIs are now available to use inside your VPC, with support for more services coming soon such as Key Management Service (KMS) and Amazon Cloudwatch.

這樣就不用弄 proxy server 然後在上面管一堆 policy 了... (先不講自己搞 HA 的麻煩事,光是有些程式還得 patch 才能支援 proxy 就會想翻桌了 XD)

CMU 推出 Product Management 的課程

CMUCS (Computer Science) 發的新聞稿:「Carnegie Mellon Offers New Master's Degree in Product Management」。

副標也清楚寫出是一年的課程:

One-Year Program Turns Computer Professionals Into "CEOs of the Product"

除了 CMU CS 外,也結合了 CMU 的 Tepper Business School 一起開:

A joint program of the university's School of Computer Science (SCS) and Tepper School of Business, the Master of Science in Product Management (MSPM) program will start January 2018.

另外一個不同角度的 Product Management。

結果 AWS Console 對 EC2 的 IAM Role 被拔掉了...

在 console 上發現不見了,跑去 forum 上看看是不是有其他人遇到同樣的問題,結果發現被拔掉了:「Attach IAM Role to existing EC2 instance in console not available」。

On Friday, Feb 24th, we were made aware that under certain conditions, the feature was not working for customers using the EC2 console. As a result, we have temporarily removed this capability from the EC2 console, but we will enable this feature when this issue has been resolved.

Ouch... 只好先用 CLI 了...

AWS 的稽核報告服務:AWS Artifact

以往要取得 AWS 的稽核報告都必須簽署 NDA 並透過 support ticket 取得 (或是找窗口拿),現在 AWS 把這件事情做成一個服務:「Introducing AWS Artifact: Speeding Access to Compliance Reports」。

服務叫做 AWS Artifact,還是要簽保密協議,不過電子化了:

You can start downloading the audit reports in the AWS Management Console today. Many of the documents are confidential and require you to accept Amazon’s confidentiality terms and conditions, but after you review and agree to those terms, you will be granted instant access to review documents.

這樣取得資料就可以透過系統直接拉出來了:

To document the current and historical compliance of the AWS infrastructure and services, many AWS customers provide compliance reports—including those for ISO, SOC, and PCI—to their auditors or regulators.

GitHub 又多了許多功能...

GitHub 上個禮拜推出了不少功能出來:「A whole new GitHub Universe: announcing new tools, forums, and features」。

功能多了不少,但比較亮眼的主要是 Project 的功能,界面上有點像 Trello

操作上也可以看到,一個 repository 可以開很多 project,然後在裡面移來移去:

With Projects, you can manage work directly from your GitHub repositories. Create cards from Pull Requests, Issues or Notes and organize them into custom columns, whether it’s "In-progress", "Done", "Never going to happen" or any other framework your team uses. Drag and drop the cards inside a column to prioritize them or move them from one column to another as your work progresses.

唔... 這樣好用不少 :o
