Hi! I would like to create a blog with Discourse. I am not planning to do any specific modifications on the forum except of the installation of the Basic plugins from here. My users cannot create new topics, they just can answer the ones I created. I would like to start a budget friendly way, so I found these two really cheap, ~£3 Discourse hosting alternatives:
The most notable differences between the two are the processor and the SSD size. While OVH has a really fast CPU (faster than DO or Linode), Scaleway has Atom CPUs which are about 2-3 times slower. However, both of them can run Discourse.
The SSD size which worries me more. OVH has only 10 GB SSD which can be problematic for Discourse. I am planning to use S3 for backup and images, but it can be problematic in the future or at an upgrade. OVH offers two option to fix this problem: VPS SSD 2 has 20GB SSD (and 4 GB RAM!) for about £7 or you can buy additional 50GB SSD for £7.
On the other hand Scaleway has 50 GB SSD from the start but slower CPU.
I would go with OVH if 10 GB SSD can be enough for my use case. When I need more SSD I can just use one of the fore-mentioned update options. The reason I would prefer OVH is the performance. It can be useful if one of my blog post get attention on HN or any of a popular websites. Is 10 GB SSD enough for Discourse?
If it is not possible to safely use Discourse on 10 GB SSD, I will go with Scaleway. My problem is that I am not sure whether it can handle higher peaks in traffic. It is not an option to upgrade on Scaleway as you will still use Atom CPUs (but with more cores) which has bad single core performance. Can Atom processors handle occasional higher traffic on Discourse?
