Can't deny that their servers are affordable, a college of mine chatted with them a few days ago and asked if they could provide a dedicated server (32GB RAM and a 4core CPU with 3.6GHz (4GHz burst) and 2TB HDD), luckily they could so my college asked where it was hosted, they answered in a German datacenter with collocation. So far no trouble. Then my college asked about the price which would be $70/month. My college then found out that this datacenter charge $119/month only for the rack so they would have lost $49/month if my college bough this server.

Same thing goes for the VPS plans, 32/2 = 16, 16*6 = 96 which is less than $119. Or for the expensive plan: 32/8 = 4, 4*20 = 80 which is also way less than $119. Either they're just generous to us or they're overselling. The guy my college talked to also explained their CPU division this way: 4 vCores = 1 dedicated thread
2 dedicated threads = 1 physical core of the CPU 3.6 GHz to 4GHz. But even with that division of CPU cores you'll end up with this equation: 32/2 = 16, 16*6 = 96.

My college isn't very trust able however so could someone explain how this all works in reality?

No overselling :)

4 vCores = 1 Dedicated thread

2 Threads = 1 Physical Core.

for each GB of RAM, you get 1 vCore. We have 32 GB RAM on our main nodes.  So, 32 vCores are allocated to VMs. I hope this makes it clear. And the rack is shared (I don't pay for the rack alone, there are other partners and customers who pay for colo in that rack). We don't make much profit, but the pricing's just sustainable. Let me know if you have any other queries.

That's literally the definition of overselling. Dividing a physical core into vCores doesn't make it faster :) But at least you're being honest about your division model so that people know how much pressure they can put on their servers.

Like who? how many rack units do you have in total together and how many does your server(s) require? what do you pay together ($119/month seems to be taken out of thin air). Any server rent or do you own your physical servers? I just wanna prove to my dumb college that you do make some profit, otherwise you wouldn't run this, right.

You're getting dedicated CPU space at last, right? Processing power, on the CPU, is reserved for you, depending on what plan you choose. About the other costs and rack info,we're in a RTO contract with another partner who takes care of it. However, we've recently started renting servers from Hetzner directly for Germany location.

Well technically you're right. But that processing power is in reality 3.6GHz/8vCores = 450MHz, which means 2x450MHz = 900MHz on the cheapest plan. Allowing burst would be a good thing if you wrote 450MHz per core (the truth) instead of 3.6GHz which you get from your dedicated cores. But instead you're promoting 3.6GHz and hope that customers who buy less than 8vCores won't notice the fact that they can never get 3.6GHz in reality. Overselling is a common phenomena so I'm not blaming you for it but you shouldn't deny the fact that you're doing it.

Users end up getting somewhere near the 900 MHz mark, when these limits are imposed, and these days, I've been able to let things run normally without running into CPU issues, We've had no complaints about the availability of CPU, so I'm pretty confident that things are running smooth :)

I'm not sure why it'd be 450 MHz. I must be missing some math somewhere. Anyway, users end up getting somewhere near the 900 MHz mark, and these days

450MHz on each vCore, if you divide a dedicated core into two threads then divide it into 4+4 vCores it is 8 vCores per dedicated core. Intel CPU's already have threads built into the hardware dividing each dedicated core into two threads where instructions run in parallel. 900 MHz is the sum of two vCores which means that it only works on multi threaded apps, luckily the MTA server is multi threaded as far as I know.

This approach won't lead to any issues at all, you could even divide each dedicated core into 16 or 32 vCores and there wouldn't be any issues. However when all the cores are in use and under high load people will notice CPU lag. This lag could and will most likely be caused by other customers instead of your own apps and that's the problem with overselling. The reason why you personally haven't faced any lag is because You've tested this on a single VPS running on a empty 4Core dedicated server with 32GB ram, when you're alone you'll get all the max allocated processing power for yourself.

Why should they complain? at this stage you probably only have a few customers which means that they can use all the processing power they're paying for (i.e 3.6GHz)

We did stress test using 16 VMs, replicating an environment when all VPSes would use full CPU. And all cores being in constant use is a very rare occurrence in a production environment. Under high load, people will ofcourse notice lag under high usage, isn't that what should be the case? You can't expect to run a high load application in the lowest plan and not experience lag.

@Donald Duck as much as i know and i can see is that you are trying to say that they are overselling this. You got any proof for that? He has been saying since first post that they are not overselling and he has explained it very clearly. Maybe, stop this thing here mate :)

Edit:- No offense, just solving the matter.

Good Luck

Dividing a physical core with 3.6GHz processing power into 8vCores and then advertise the frequency of the dedicated core (3.6GHz) is overselling. However the solution to that is really simple, just write the actual amount of processing power you have the right to use per vCore (which i have already calculated to 450MHz (500MHz burst)). It's a small thing, and I'm well aware that there are many hosts advertising the total amount of a specification instead of what you actually get. OVH for instance brag about their 40TBit/s DDoS protection which is basically their total capacity in all their data centers summed up. That leaves only a few MBit/s in actual ddos protection assuming all resources are shared equally between all customers.

I'm not against the concept of overselling, I think it's a good thing since it allows cheaper servers under the assumption that the distribution of system resources can be shared in a fair way. What I am against however is when people do false advertising or lie to their customers. I mean you wouldn't sell the same 2L bottle of coke to 8 different people and hope they won't notice that they can't drink those 2L themselves but only 2/8L which is 0.25L coke per customer. It's disturbing somehow that service providers gets away with this kind of false advertising.

I wish you all the best luck with your company but please be honest about your server specifications in the future. It's fully acceptable to divide a dedicated core into 8 vCores but don't try to convince your customers that it wouldn't be any difference between 1 vCore and 1 dedicated core because there is a pretty big difference.

tbh, all your calculations are wrong. Think with senses, only nubs will give the fake information about their hosting services, About this guy, i know him since a long time and i can bet that he isn't overselling. Well, that's your thinking that they are overselling, but trust me, they are not.

Have a good day :)

Did I?

And your calculation is wrong, because you didn't consider the hyperthreading part. So, users of the lowest plan get to use 1.8 GHz - 2 GHz(burst). You're going around in circles, comparing the sharing of CPU to cokes. Ofcourse I won't be charging each person the price of full bottle if I give him 1/8th of it, right?

Alright, my mistake then, I did forgot about the hyperthreading. But this is still 4 vCores per thread and each core has 900MHz (1GHz burst). 1.8 GHz - 2 GHz(burst) works only for multi threaded applications.

More like 1/4 of a bottle, but only for as long you advertise the capacity of the dedicated thread without handing out the information about how many vCores you run per thread (4).

Well the fact that you know him doesn't change the logical facts about the mapping of CPU threads/cores to vCores. 4 people sharing a bottle of coke still means that each and one of them get less than if they bought their own bottles right. It's basic math :)

There's a reason for the 3 days no questions asked refund policy, right? Everything doesn't work out for everybody. If it doesn't work for for you, you're welcome to get a refund.

Did we ever, in our plan specs, mention the frequencies of our vCores? There's a reason why we write vCores instead of only cores, right?

According to my college you did say 3.6GHz and 4GHz burst per vCore during your chat. Did you or did you not? I don't know, I'm just asking out of curiosity because I don't fully trust him, as I have mentioned earlier. I just wanna hear both sides of this conflict before making my own opinion.

Aight, I'll clear that up for you.

http://prntscr.com/ek93lj

I just mentioned the topology, when he asked me about the CPU. I mentioned the frequency only when he asked me about dedis that we sell, and the host node (can't remember clearly), anyway here's the transcript. http://prntscr.com/ek94np I never mentioned that much frequency per vCore.
