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

DigitalOcean 總算是跟上來了...

DigitalOcean 在隔壁 Linode 都升級一年半年後 (參考 2016 年的文章「Linode 記憶體升級,以及新的日本機房計畫」這篇),才想到沒有競爭優勢了:「Kicking Off the New Year with New Droplet Plans」。

在 Standard Droplets 的部份,主要就是把記憶體的量補上來,另外提供一些變化:

另外 Optimized Droplets 也有一些變化,不過就沒有太關注了...

離開 DigitalOcean 很久了 (現在主力都是 Linode 跟 Vultr 了),這次端出來的菜盤看起來還是不太行...

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...

Amazon Lightsail 推出 Block Storage 與 Load Balancer

Amazon Lightsail 推出了 Block Storage (11/14) 與 Load Balancer (11/29):「Introducing additional block storage for Amazon Lightsail」、「Amazon Lightsail adds load balancers with integrated certificate management」。


Block Storage 有不少 VPS 都有提供了,像是 Linode 的「Linode Block Storage (Fremont beta)」(雖然還在 beta)、DigitalOcean 的「Storage on DigitalOcean | Highly available Block Storage」以及 Vultr 的「High Performance and Cheap Block Storage - Vultr.com」。

AWS 算是很早就有這個服務 (Amazon EBS),這邊應該只是把系統整合進來...

另外一個是這幾天推出的 Load Balancer,目前應該只有 Linode 的「Ensure High-Availability with NodeBalancers - Linode」比較知名。AWS 上的 ELB 有不少選擇可以用 (ELB Classic、ALB 以及 NLB),不過公告裡沒特別提到... 比較特別的是提供免費的 SSL Certificate 吧?這在其他家主要得靠 Let's Encrypt 來做,在 AWS 上應該是整合了 ACM

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)

Amazon Lightsail 支援 Windows 了

Amazon Lightsail 決定支援 Windows 了,算是其他目前幾家領頭的 VPS 還沒進入的領域:「Amazon Lightsail Update – Launch and Manage Windows Virtual Private Servers」。

由於多了 Windows 的授權費用,價錢貴了不少:


You can try out a 512 MB server for one month (up to 750 hours) at no charge.

不過不是所有 Amazon Lightsail 有開的區域都支援 Windows:

This feature is available today in the US East (Northern Virginia), US East (Ohio), US West (Oregon), EU (London), EU (Ireland), EU (Frankfurt), Asia Pacific (Singapore), Asia Pacific (Mumbai), Asia Pacific (Sydney), and Asia Pacific (Tokyo) Regions.

不過還是不知道 Amazon Lightsail 進入這塊市場的想法是什麼...

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」。


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

Vultr 提供 $2.5/month 的方案

Vultr 宣佈了更小的方案:「The Vultr Cloud Is More Powerful Than Ever!」。

本來的 $5/month 的方案從 768MB RAM 變成 1GB RAM (早期應該是 $5/month 方案裡面記憶體比較多的),現在這樣等於跟上 Linode 的新方案,對於跑有在跑資料庫的使用者還不錯。

另外多推出了 $2.5/month 的方案,20GB SSD + 512MB RAM (500GB bandwidth),對於需要動態的小站台應該也夠用了,反正是 SSD,把 file swap 開起來可以跑不少東西了。

來找時間把 blog 的機器降下去...
