Probably Moving To Upcloud Server From Azure

It’s been almost three years I’m amongst Azure together with to endure honest I never had whatever issues. However, I flora something interesting happening recently. Everytime my server was striking past times high traffic book (either a shipping service went somwhat viral for some unknown argue – I hateful come upwardly on, my posts are therefore badly written fifty-fifty I don’t know why anyone but me would read those. .. together with also it happens when people uses my ain guide to DoS my ain server ( ¯\_(ツ)_/¯ ) – yeah, hapless my bad!) Ideally this is non a occupation for me because my server is over-spected for to bargain amongst 5k-10k users per solar daytime but Azure late seems to have got changed something putting limitations on IOPS together with Disk R/W priority. What that agency is when I larn striking past times high trafic book everything would exactly ho-hum down. Again, non a large bargain but it bothers me when I have got something that is out of my control. I similar that command over my ain server together with resources. Almost out of curiosity, I looked roughly together with flora UpCloud.com who claims they have got the beyond SSD performance together with highest IOPS! Now, everytime I’ve seen these I larn really skeptical but since signup was costless (well form of, I got a referral code from a friend that adds 25$ credit to the account). I signed upwardly hesitantly together with decided to practice a server together with practice some testing together with therefore compare that to Azure Virtual Machine. The results are (very) interesting!

UpCloud VM Config


I went inwards together with deployed a measure VM inwards UpCloud amongst next config:



  1. RAM: 8192 MB

  2. CPU: four CPU

  3. Disk: 160 GB

  4. Transfer: 5120 GB

  5. Network Controller: VirtIO(Default)

  6. Disk Controller: VirtIO(Default)

  7. OS: Ubuntu 18.04 LTS

  8. Firewall: Not Included


Benchmark CPU amongst Geenbench 3


It’s pretty standard, you lot either role Geekbench three or four but since three is to a greater extent than widely used, I went for Geekbench 3. Installation is really at nowadays frontward inwards Ubuntu

Geekbench three does multiple tests to mensurate CPU performance, calculates floating signal together with checks retention speed data. In short, it does things together with creates a spider web study which it uploads to a website. My exam results for UpCloud VM is available here:

Benchmark Disk speed amongst fio


This is where my Azure VM was struggling! It’s of import that I gear upwardly the disk lag past times testing equally much I can. fio is a pocket-sized but fantastic tool to practice disk I/O benchmarking together with stress test. Installation is really simple:


root@www: /dist/Geekbench-3.4.1-Linux# sudo apt-get install fio -y

Now lets run some IOPS tests. BTW, IOPS is I/O operations per second. Usually you lot desire to exam IOPS thru random read write to disk. With fio together with IOPS the higher the IOPS, the faster the storage. For a comparison, a measure 7,200 rpm SATA drive HDD would have got a score of 75-100 IOPS.

Benchmark disk latency amongst IOPing


Now exactly because a disk tin dismiss read write faster doesn’t hateful it volition downwards good inwards existent life. There’s latency exam that you lot tin dismiss practice that volition order you lot what’s the delay betwixt each request. IOPing does exactly that. It’s a really pocket-sized tool that runs I/O requests to the disks to benchmark the fourth dimension to reply. The results display disk latency inwards the same way ping –test measures network latency. (this is similar to running whatever command amongst time inwards front end of them, you lot larn the fourth dimension output for that command.). Installing is i time again simple.

The fourth dimension higher upwardly shows the I/O latency measured inwards microseconds. The lower the delay, the amend the performance. So nosotros are looking at an avg of 199ms I guess!



Azure VM Config


I decided to pretty much clone my VM inwards Azure to practice a novel i to run the same tests. Azure doesn’t have got the same VM settings, therefore I had to become chip large on CPU together with Memory but I went for Premium SSD option. My Azure VM config: D2s_v3, costs you lot almost $65USD per month.



  1. RAM: 8192 MB

  2. CPU: 2 CPU

  3. Disk: sixteen GB

  4. Transfer: (unlimited?)

  5. Network Controller: (doesn’t say)Default

  6. Disk Controller: (doesn’t say)Default

  7. OS: Ubuntu 18.04 LTS

  8. Firewall: Included


One affair I ever liked almost Azure is it’s super stable together with I never had whatever issues other than random ho-hum disk response times. But let’s exam away…

Benchmark disk latency amongst IOPing

m amongst Azure together with to endure honest I never had whatever issues Probably moving to Upcloud server from Azure


Avg of 217ms!


What is going on?


If you lot compare the Read/Write values for Azure together with UpCloud, it’s exactly absurd. I could non believe Azure was therefore slow!


UpCloud:



  1. READ: bw=276MiB/s (290MB/s), 276MiB/s-276MiB/s (290MB/s-290MB/s), io=3070MiB (3219MB), run=11111-11111msec

Azure:



  1. READ: bw=5640KiB/s (5775kB/s), 5640KiB/s-5640KiB/s (5775kB/s-5775kB/s), io=3070MiB (3219MB), run=557409-557409msec

  2. WRITE: bw=1885KiB/s (1930kB/s), 1885KiB/s-1885KiB/s (1930kB/s-1930kB/s), io=1026MiB (1076MB), run=557409-557409msec


I hateful serisouly, nosotros are comparing 290MB/s amongst 5775kB/s READ speed together with 96.8MB/s amongst 1930kB/s write speed. This exactly cannot endure true! I hateful if this was true, I honestly don’t know how Azure fifty-fifty industrial plant together with stays inwards business. So I went together with did some research.


Apparently, Azure or AWS or some large hosts who doesn’t attention almost pocket-sized marketplace competition, they boundary these type of tests. That powerfulness explicate why the tests results are exactly therefore bad. I thought, good … lets seat that to exam anyway!How almost I download a 4GB ISO file, endeavour to re-create or deed or delete it on my Azure VM. Surely that is non stress testing, it’s to a greater extent than similar normal file-copy operations.


More Azure testing


Decided to download a Debian ISO (4.35GB inwards size) together with time it.

hmm therefore it’s 3m17.655s to download a 4.35GB file at 24.2MB/s speed. Bad? No. Could endure amend though but therefore i time again could endure express past times Debian server’s charge per unit of measurement limiting.


Now, let’s endeavour to brand a re-create of the file.

Seriously, it took 2m31.754s to re-create a 4.35GB file!


Try to deed that file to /tmp directory?

0m43.087s to delete a file? My VM’s running inwards my ain Desktop inwards spinny HDD does that faster!


How almost delete the file?

0m8.040s to delete a file!



Summary


I don’t know what’s but Azure’s Premium SSD doesn’t aspect similar it lives upwardly to the measure or promises. Azure powerfulness endure really stable together with large, but there’s things that tin dismiss endure improved. I hateful it’s exactly for Disk, fifty-fifty the CPU benchmark was exactly all over the place, Azure is nowhere close Upcloud! The alone practice goodness at nowadays I tin dismiss cry back of is the added Firewall, exactly Azure costs me roughly $65 USD per month, UpCloud is $40 USD together with peradventure added Firewall service. But I run my ain Firewalls, therefore I don’t cry back that’s a occupation for me. I also larn four CPU together with 8GB RAM along amongst 160GB HDD (not that I take away that much) amongst a savings.

Moving to UpCloud.com seems similar the correct move. I got few websites hosted on Azure, therefore it volition have got some fourth dimension but I am honestly thinking of moving my spider web server. BTW, I’ve added my promo code that should laissez passer on you lot $25 credit! ……


 


Also, I received multiple messages almost my server beingness slow(mostly from Brazilian Readers, therefore could endure portion specific). I could role some favors really; allow me know inwards comments department if my electrical flow hosting is fast or non or your full general comments regarding it. Comments are equally park anonymous together with doesn’t require signup, therefore experience free. Also, if you lot are using Upcloud, allow me know your experience! I am really non bad to deed together with I volition likely write a novel article afterward I’ve moved. Keep inwards touch!
