There is a site (usual LAMP) spinning on shared hosting. Lately, hosting has started to show the excess of allowable limits for MySQL and CPU. The site has 10-50 thousand hits per day. Some of the pages are formed by fairly heavy SQL queries.
I want to move to VDS or Dedicated. The question is how to choose the right configuration? Are there any tricks to estimate how much RAM or what CPUs are needed? The current Shared hosting shows consumed resources in the control panel in some kind of abstract units, from which it is difficult to draw conclusions.

Move directly to the dedik, recently set up VDSku and was amazed at the difference between the weakest dedik on hetzner.de and the most powerful vdskoy on firstvds. The difference was measured dozens of times.
It may happen that after you set everything up - the pages will be rendered slower than on the shared.
As for what to choose, any hetzner's Dedik will do. Tariffs here www.hetzner.de/en/hosting/produktmatrix/rootserver-produktmatrix-ex

If you can’t even see the RAM consumption, take a 4Gb VPS on DigitalOcean, the payment is hourly there, deploy a copy of the site there and test the load (artificially). Based on the results, you will see how much RAM and processor you need. At the time of testing, it will be useful to install the free version of NewRelic - just look at the load graphs, it installs in 1 minute.
After the test, you can pick up VPS on Linode.com, Amazon, Rackspace, Joyent - these are hosting leaders. Well, or on the same Digital Ocean - they are trying to capture the market by dumping prices and fast support, which is in our favor :)

If you want, I can take you to my Xeon * 8/16 gb RAM ... isp panel ... everything costs ... (just the server is not loaded now ... average top - 0.5)

According to the process, hosters write the allowable limits on the site there and it's worth a look, usually no more than 5% of the XEON core. So potentially any VPS will suffice.
Another question is how much are you willing to pay per month.
Already for 10 euros you can easily take Atom N2800 , 2Gb RAM, 500Gb HDD from OVH.

Servers are now standing like 5 times to go to the store.
Take any server for 32 64 oz, believe me, it's enough for an average project.
Make sites mobile , make backups , use third - party dns . And you will always be ready to quickly migrate to any other equally cheap server.
