Server Specs For An Online Casino Website

The spec depends on what resources each user consumes.
Your main concern would potentially be the network throughput.

You gave to look at the specs of the components you use on the site
And tabulate the resources the vps needs based on your expected demand.

The items you plan to use should include resource per user consumed on the vps. User could be reflecting a grouping..... I.e. For 100 simulteneous users.......

Hello,
We set up servers for various online companies. We worked with many casino sites. I must say that if you are going to have many visitors, you'd better go with a Dedicated server. Yes, it is expensive, but it is much more powerful and reliable. Here is one of  the sites that we were setting up - http://casinobonuspromotions.co.uk/bonuses-by-provider/netent-bonuses/. There is a also a list of other casinos at that page, they all use dedicated servers too.

You dont need it. Develop the site only. Create a structure and put demos of free slots like here https://affgambler.com/all-free-slots/. See? You dont need any VPS...

you have to make a lot of steps)))firstly, just decide what type of casino site do you want? affiliate, online casino or review site?

Try to make it like http://slotsspot.com/online-free-slots/ It seems to me that this is an ideal variant
