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):


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

Microsoft 虛擬化的兩個消息:Azure 被打臉以及 AWS 推出轉移工具

首先是 VMware 發文打臉 Microsoft 說他們所宣稱的轉移工具 (從 VMware 轉到 Azure 上) 並沒有 VMware 原廠支援:「VMware – The Platform of Choice in the Cloud」。

然後 AWS 則是推出了從 Hyper-V 轉移到 AWS 的工具:「Migrate Hyper-V VMs to AWS with AWS Server Migration Service」,這邊倒是沒提到官方支援...

這臉不只是腫腫的而已了,有種連續技的感覺 XD

Microsoft Azure 宣佈正式支援 FreeBSD

Microsoft Azure 宣佈支援 FreeBSD:「Microsoft has created its own FreeBSD image. Repeat. Microsoft has created its own FreeBSD image」,Microsoft 的正式公告在這:「FreeBSD now available in Azure Marketplace」。

Microsoft 所作的 patch 都有進 10.3-RELEASE 裡,主要是對於 Hyper-V 虛擬化後的效能補強:

The majority of the investments we make at the kernel level to enable network and storage performance were up-streamed into the FreeBSD 10.3 release, so anyone who downloads a FreeBSD 10.3 image from the FreeBSD Foundation will get those investments from Microsoft built in to the OS.

像是 10Gbps 網路這部份就有明顯的改善:

For example, our measured networking throughput on a 10Gb network on FreeBSD 10.1 was 2Gbps. With 10.3, we’ve been able to achieve over 9Gbps in testing


Akamai 與 Microsoft Azure CDN 合作的方案進入 GA (General Availability)

先是在 Akamai 的網站上看到說明:「Microsoft Azure CDN from Akamai Enters General Availability」,另外裡面有提到 Microsoft 的公告:「Microsoft announces general availability of Azure CDN from Akamai」。

所以 Microsoft Azure 現在提供三個不同的 CDN 方案:

  • Azure CDN Standard from Verizon
  • Azure CDN Standard from Akamai
  • Azure CDN Premium from Verizon

其中 Standard 方案的價錢都相同,而 Verizon 的 Premium 方案大約是兩倍價錢,沒猜錯的話應該是 Verizon ACCELERATE?以前 EdgeCast 的 ADN 產品線?

估計 Amazon、Microsoft、Google 雲端服務平台的相對大小

在「How much bigger is Amazon’s cloud vs. Microsoft and Google?」這篇文章裡用營收來估算...

But, a new report from New Hampshire-based firm Technology Business Research estimates Amazon’s cloud revenue at more than $4.7 billion this year. TBR pegs Microsoft’s public cloud IaaS revenue at $156 million and Google’s at $66 million. If those estimates are correct than Amazon’s cloud revenue is 30 times bigger than Microsoft’s.

如果用估算的營收來比較,與第二大的 Microsoft 相差 30 倍,超級大的差距...

Windows Azure Platform 平台,其中 CDN 的部份的測試...

透過台灣微軟的幫忙,一個月前拿到了一組 Windows Azure Platform 的帳號測試,來寫一下感想好了。

在管理介面時會被提醒需要安裝 Sliverlight。沒有 Silverlight 的只能使用基本介面,同時也在登入時說明 2011 年初會把舊介面關閉:

抱歉,即使活動辦得很精彩,我還是沒興趣裝 Silverlight... 所以下面的測試都還是以基本版的測試為主。

能看的文件不多,而且要在登入後才能看 Help and Resources (這是 non-Silverlight 版本)

抓了 VSCloudServiceHelp.chm 後,打開來發現只有標題能看,每個章節都看不到內容:


Windows Azure CDN 的台灣 PoP...

自九月開始,微軟的 Windows Azure CDN 增加了兩個 PoP:「20 Nodes Available Globally for the Windows Azure CDN」,參考文章最後的「UPDATE - 9/1/10」部份。

  • Seoul, KR
  • Taipei, TW

這樣又多了一個 CDN 在台灣有 PoP... 其他幾家是 AkamaiCDNetworks

在台灣放的點是是方電訊,以微軟自家的 hp.msn.com 測試 (目前是 CNAME 指到 msnimstore.vo.msecnd.net),從 HiNetSEEDNet台灣學術網路 (透過 SEEDNet 轉過去) 都會被導到台灣的點,而台灣固網則是被導到美西,看起來是因為台固與是方是走 TWIX...
