I'm moving from shared hosting to VPS. Which tariff to choose?

Question

Network administration

Good afternoon!
There is a shared hosting at the rate "Wordpress 2" (20 GB SSD, 512 MB, other parameters here )
. There are three rather voracious sites on the hosting. Hosting constantly complains about overloading.
There is a desire to switch to VPS, managed by Vesta CP.
What rate to take? will this one fit? VDS SSD-1 (20 GB SSD, 512 MB, other parameters here

Answer 1

it would be better to take 1024 MB of RAM, since Vesta uses about 350 MB - 400 MB + the site will still be.

Answer 2

If you do not have administrative skills, it is better to find another shared, more decent.
VPS is a server, it must be configured, it must be constantly monitored, updated, etc.
Simply installing the panel is not enough for normal operation.
Vesta, moreover, is an extremely unfortunate choice, primarily due to the fact that it is a rather low-quality product, and now, also with a serious unpatched vulnerability...

Answer 3

1. Don't buy VDS without a test. The processor or disks can be dead
2. Put a normal control panel. ISPmanager is the best option. At worst, Centos Webpanel or BrainyCP. There you can at least edit the set of software after installation.
3. More memory so that the base cache and opcache can be transferred there as much as possible.

Answer 4

it is obvious that for gluttonous sites it is necessary to take operatives from 2 gigs at least and 2-4 cores
