Is it worth switching from a Dedicated Server to a VPS?

Question

Network administration

I have a seyas in Hertzner server with 4 cores with 8 gigs of memory, everything flies.
10 thousand visits. 40 gigabytes of traffic. It costs debian + nginx + php-fpm.
You have to pay 50 euros per month. There was a question, maybe Digital Ocean VPS or Linode? Or how? In the same place, you can also put memcache and a couple of domains and configure it as you want? Can chtoit on the server to look at the statistics of some thread?
What to do with the growth of visits, how to calculate the load?

Answer 1

4 cores and 8 gigs on the ocean costs $ 80, it will be more expensive to switch.
Plus, on the ocean you are dependent on your neighbors, the neighbor will start loading the disk, everything will fall for you, it’s checked.

Answer 2

You are trying to fuck yourself. DO for 5 bucks and will work for 5 bucks, not 50.

Answer 3

10 thousand - nothing, even an hour (evenly smeared).
A virtual machine for $10-20 with ssd will cope with such a load if you configure something trickier than apt-get install apache2.
Another question is that if you have attendance peaks, then the virtual machine may not be able to cope with the peaks.
Anyway, judging by the price and configuration you have a VERY old server. For 50 euros you can find something 4 times faster. And again, switching to ssd (it doesn’t matter, on a dedicated ssd server or on a virtual machine, if it’s not very brazenly overselling there) will give a very large increase in site response speed. And due to the fact that the processes will work less in total, then less memory may be needed.
In general, I'm all about the fact that a digitalocean virtual machine with 8 GB of memory for $ 80 will be faster than your server. A virtual machine for $40 bucks will be comparable in terms of load capacity, but the site will respond faster.
However, if you do not use the entire server resources (except for io), then there is no point in buying fat configs.

Answer 4

First you need to install monitoring and see how much resources the server consumes (RAM, CPU, disk space/iops, network bps/bandwidth).
After that, look at the price of the corresponding virtual machine.
Put Munin, Collectd or Cacti.
