Usually shared hosting services suggest customer to switch to virtual private servers when the load of the account becomes too high, but actually a misconfigured vps is probably worse than a common shared hosting account. This is one of the most common situation that leads to the use of virtual private servers, it is a common situation for personal accounts when you need a little more, but not too much.
So when shifting to VPS is a good idea? For inexperienced people who just use web hosting accounts to host simple website such as blogs it is hard to give a simple explanation. There is always the need to do a comparison between the performances of the web hosting account in use and an ideal vps.
What is an ideal VPS?
An ideal vps is a vps you actually know, you know what will be installed on, what OS it will use and so on…It requires a little time to experience various situation and choose the right one, but this also depends on the kind of VPS you use, a.k.a. managed or unmanaged.
There are a lot of benchmarks on the web but I would never really never suggest to consider those…there are a lot of powerful benchmark software out there from common I/O reads to full-featured network tools to little “siege” tools to test performances and responsiveness both client and server side .
When the time is right?
Smooth shifts are the right ones…never take do just a drastic drop of one hosting for the other…test thoroughly, of course it also depends on importance of the things you are shifting over. I would think of the shift as a really step by step process composed by various level of software commitment, but I know this can really be time expensive and sometimes superfluous.
– For little shifts I would go for the rule “no problems for 1 day, good to do”. Which really easy if you haven’t got a problem in 24 hours after the shift, then you can start switch DNS and other routing systems you are using .
– Check, check check! One more way to deal with a migration is to compile a small list of edge scenarios you would think the system would behave badly, and run it, after you have checked you can start the shift.
The other way around
I just covered some quick tips to shift to a vps from common web hosting platforms, but what about shifting to a vps from dedicated servers? It would actually mean you would “shrink” your environment but really not all the times. A lot of VPS plans actually are able to offer much more resources proportionally at their cost, of course you have to make sure whoever you are buying from know what he is doing, because usually big VPS resources for cheap plans means, shared resources between VPS, but a proper system can handle resources like each VPS had its own making the server side arrangement completely unnoticeable by the client.
I have actually seen a lot of VPS offers with a network speed from straight 1 Gbps ports whereas a lot of big dedicated servers offers never more than 100Mbps , and if they do, it usually is 3 times the original price; Of course it is different from data center to data center…so there isn’t really a fixed rule.
In other words…resources is really not what makes VPS differents from DEDI servers.
I would really find a lot of reason for switching from dedi to vps, like less time wasting to configure it since a lot of Virtual private servers comes with pre-configured operative systems, more direct access thanks to web platforms such as the one offered SolusVM.
The other way around is really possible, there is no “do not cross” signal, and a lot of times you would have hoped to have made a “virtual” step backward sooner.
