Rasmus Lerdorf 關於 VPS 的介紹測試...

Rasmus LerdorfPHP 的發明人,純粹是有趣的角度看這篇文章:「Testing VPS solutions」。

文章裡比較了十家 VPS 或是可以當作 VPS 的雲服務商,先直接講重點,看起來他最後選了 Vultr

A serious competitor to Digital Ocean. I would use this.

不過 Vultr 有個讓人不太舒服的地方 (對我而言) 是登入機制沒有 2FA,所以只能透過 Password Manager 用強密碼保護。不過除此之外都還算不錯。

不過既然是 Rasmus,在提到 MicrosoftAzure 才會是重點 XDDD:

This one was painful. Yes, I have a bit of a Microsoft aversion, but I tried to keep an open mind. Read the full description of my Azure adventure. Expensive, apparently no IPv6, slow disk IO, and I couldn't figure out block storage options. Definitely not for me.

然後在測試 Azure 時的評語就更酸了:

Oh Azure! This one is going to get a bit ranty. I Spent a good 20 minutes clicking around the provisioning Web UI. To be fair, it is more geared to people needing to provision a lot of servers. Doing a single one like this is not the target audience as far as I can tell. But still, instead of presenting a couple of standard options and a way to build your own custom config, Azure gives you 92 options (depending on which region you select):

繼續抱怨找不到價錢:

I also got super lost trying to figure out what it would cost to bring the VPS up to 500 GB of persistent storage. And then to make things even more confusing, when I started the virtual machine creation process and came to the "Choose your virtual machine size" step, I got a bunch of different options not included in the above list with most of them listed as "Not Available" including both the A4 v2 and F4 options I had so carefully located.

然後還有奇怪的 agent 在跑:

The Azure VPS also had the heaviest provisioning agent of all the ones I tested. It looks like it is doing a heartbeat once per second and doing a (non-ssl) GET request to an IIS server upstream asking it for a "GoalState". I listened and checked what the IIS server responded with. The response from the management server is in the GoalState addendum below. It is mostly self-explanatory, I think.

相較於其他家 VPS 的評測,這部份的長度與酸度都頗不賴的 XDDD

Vultr 也推出 Bare Metal 的機器了

AWS 推出 Bare Metal 版本的 Instance 後 (參考「Amazon EC2 推出第一款 Bare Metal 的 Instance」),Vultr 也推出 Bare Metal 機器了:「Deploy Bare Metal Cloud Servers With Vultr!」。

目前先在新加坡推出,之後會再往其他地區推出 :

We are first introducing bare metal in Singapore and more locations will be rolled out in the coming weeks.

在「Vultr Bare Metal - Dedicated servers with hourly billing. - Vultr.com」頁可以看到目前只提供一種機器,E3-1270v6 + 32GB RAM + 2*240GB SSD,一個月 USD$300 ($0.446/hr)。

對照 AWS 提供的 E5-2686v4 + 512GB RAM + 15.2TB SSD,Vultr 的這個規格很微妙... 會有 bare metal 需求通常是因為效能上的不足,但你給的這個規格感覺就鳥鳥的,對效能的幫助好像不大啊...

DigitalOcean 默默的推出了 3GB RAM 的方案

是在 Twitter 上看到這則 tweet 才發現 DigitalOcean 多了 3GB 的方案:

如果去翻資料,可以看到官網是在 2017/11/082017/11/15 中間增加的...

看規格可以看出來記憶體很多,但 CPU 與 SSD disk 空間都不是很多,有種 Amazon EC2 裡 R 系列機器的感覺,但卻沒放到 High Memory 的列表內 (DigitalOcean 已經有推出 High CPU 與 High Memory 的機種了),應該是入門款的想法?

不過價錢還是比同業貴不少... (相比於 LinodeVultr)

靜態站台的選擇...

Hacker News 首頁上看到的文章,講 Jekyll 一路跟 Amazon S3Amazon CloudFront 接上去的步驟:「Jekyll CBCD Pipeline to the Cloud」。

我看了以後覺得好麻煩 @_@

然後回頭看 Hacker News 上的評論:「Jekyll Static Web Hosting – Deployment Pipeline on AWS | Hacker News」,看到這段:

What a nightmare. I'm sure there are use cases for a setup like this, but this is not the system I'd like to maintain. I use Jekyll because of it's simplicity. I edit my site in my favorite text editor and rsync to shared hosting.

好多人都有同感啊 XDDD

另外有人提到 Netlify 這個服務:

After I discovered Netlify, I'm kind of thinking "why bother". It's free, I just push to my repo and they take care of all the building/publishing/hosting/CDNs, and they're very responsive for support and have high availability. I'm a very happy customer (or rather leech, as I don't pay anything).

下面評價看起來還算不錯,而且有 free tier 可以用,也許可以找機會玩看看...

Imgur 上 HTTPS

Imgur 宣佈 HTTPS 化:「HTTPS on Imgur」。

Today, we deployed HTTPS by default on Imgur. All traffic is now redirected to https:// and, as of now, HTTPS is the default on all Imgur URLs.

總算是上線了... 先前是靠 HTTPS Everywhere 做。

DigitalOcean 推出 High CPU Droplets

DigitalOcean 推出了高 CPU 使用量的 VPS 服務:「Introducing High CPU Droplets」。

價位從 USD$40/month 開始。相較於 Standard Droplet,CPU 的速度提升到 2.5 倍速 (平均):

The current CPUs powering High CPU Droplets are the Intel Broadwell 2697Av4 with a clock speed of 2.6Ghz, and the Intel Skylake 8168 with a clock speed of 2.7Ghz. Customers in our early access period have seen up to four times the performance of Standard Droplet CPUs, and on average see about 2.5 times the performance.

目前早期先開放這些區,八月底會開 FRA1 與 LON1:

These Droplets are available through the Control Panel and the API starting today as capacity allows in SFO2, NYC1, NYC3, TOR1, BLR1, and AMS3. They will be available in FRA1 and LON1 by the end of August.

等 benchmark 數字出來後才會比較清楚跟 AWS 上的 c4.large 系列比起來如何... 不過現在看起來 DigitalOcean 想直接跟 AWS 對決?如果技術上沒有特別的東西,應該會蠻辛苦的... (因為只剩下價格)

Amazon Lightsail 多了一堆地區...

AWS 宣布 Amazon Lightsail 多了九個地區:「Amazon Lightsail Update – 9 More Regions and Global Console」。

這次多了亞洲區:

At re:Invent we made Lightsail available in the US East (Northern Virginia) Region. Earlier this month we added support for several additional Regions in the US and Europe. Today we are launching Lightsail in four of our Asia Pacific Regions, bringing the total to ten.

不過這個產品還是讓人覺得很微妙 XDDD

GitHub 的整合性平台

GitHub 宣佈了 Marketplace,一個將各種外部 plugin 資訊整合起來的平台,讓開發者更容易尋找有哪些工具可以幫助開發:「Introducing GitHub Marketplace and more tools to customize your workflow」。

GitHub Marketplace is a new way to discover and purchase tools that extend your workflow. Find apps to use across your development process, from continuous integration to project management and code review.

可以看到目前分成五大類:

  • Code quality
  • Code review
  • Continuous integration
  • Monitoring
  • Project management

不過看了一下,目前上 Marketplace 的還有點少,不知道是不是對於要上架的公司有另外收費...

AWS CodeCommit 總算支援東京區了...

AWS CodeCommit 宣佈支援東京、新加坡、雪梨、法蘭克福四個區域了:「AWS CodeCommit is Now Available in Asia Pacific (Tokyo), Asia Pacific (Singapore), Asia Pacific (Sydney), and EU (Frankfurt) Regions」。

AWS CodeCommit 算是純 Git Hosting 的服務,但可以很容易跟 Lambda 之類的東西整合,所以要串其他的服務也不難。之前一直沒用主要還是會抱怨他的 latency...

比較特別的地方是 SSH username 的地方需要用他產生出來的 name,需要在 ~/.ssh/config 裡面設定,會比較麻煩一些,其他的到是還好。

然後由於 SSH 是採用 Trust on first use 的概念,不像是透過 PKI 稽核架構有 Root CA,所以 AWS 有提供每個區域 CodeCommit 的 SSH Fingerprint,包括了 MD5 與 SHA256 的值:「Setup Steps for SSH Connections to AWS CodeCommit Repositories on Linux, macOS, or Unix」。

前五個 active user 提供這樣的量,對於個人應該是夠用:

Unlimited repositories
50 GB-month of storage
10,000 Git requests/month

而超量的部份收費應該也還好:

$0.06 per GB-month
$0.001 per Git request

是可以考慮把一些 Private Repository 從 GitHub 上搬出來了... (當初買 GitHub 是因為他的穩定度比 Bitbucket 以及 GitLab.com 都好不少)
