I am currently using Ubuntu 17.10 using Oracle VirtualBox on USB as hard disk.
Would like to know if it is possible to install Ubuntu on cloud for personal use and will it be faster compared to current approach?

It depends on your Internet connection speed and the time slice the cloud server allocates to you. Compare this to the speed of your own hardware.

In my case although I have a 1000 Mbps Ethernet and router my ISP limits me to 50Mbps download and 10 Mbps upload speed.

On the other hand my NVMe SSD delivers 3,000 MBps which is to say 24,000 Mbps read access and 2,000 MBps which is to say 16,000 Mbps write speed.

So for reading/downloading my SSD is (24,000 / 50) 480 times faster and for writing/uploading it is (16,000 / 10) 1,600 times faster.

This assumes the cloud computer finishes its computations instantaneously, has no other clients using it and the backing storage responds without delay. Otherwise assume your own PC with NVMe drive is 5000 times faster at reading and 16,000 times faster at writing.

That said these are purely technical measurements and the human eye can only notice changes at 1/30th of a second. So if the difference was waiting .001 second and .000001 second you would not notice. But if it was waiting .1 second vs. 100 seconds you sure would notice.

I'm using an NVMe SSD, which is 8 to 12 times faster than an SSD which in turn is 4 to 8 times faster than a hard drive which in turn is 10 times faster than your USB (estimated).

So you might very well see the same performance if not better on a fast expensive cloud server.

But what I would really suggest is upgrading your $10 USB to a $50 HDD or a $200 SSD or better yet a $400 NVMe SSD for the best cost/benefit ratio.

  • Thanks for your answer in a detailed way :). Was searching for nvme after your reply but lots of options with variations. I have old dell L502X xps model with legacy boot. Will it be possible to suggest a COMPACT nvme that I can use for Ubuntu installation ? – Shrikant Prasad Apr 20 '18 at 13:10
  • @ShrikantPrasad According to this Dell article: dell.com/community/Storage-Drives-Media/… you can replace your existing Hard Drive with any 2.5" SSD. The top rated Samsung EVO 850 (500 GB) is on sale from $270 reduced to $155: amazon.com/Samsung-2-5-Inch-Internal-MZ-75E500B-AM/dp/… – WinEunuuchs2Unix Apr 20 '18 at 23:08
  • I already have internal SSD. As I am looking to have Ubuntu OS in tiny pendrive/pluggable media, wanted your opinion for which Nvme can I go for. I will be plugging this in laptops with different OS and VirtualBox pre-installed. – Shrikant Prasad Apr 21 '18 at 3:07
