hello
as my title above "How many client will fit in 512MB VPS"
currently i already have reseller and have only about 30 shared client ,but right now i want to try move to vps , if you have experience with vps 512MB how many client usually could fit in this vps spec,

thanks

Between 0 and 1000. It really depends on what the clients are doing so it is hard to answer. But if you expect to run cPanel, a 512MB VPS may not be enough (cPanel is resource hog).

cPanel VPS Optimized is available for VPS refer to this for a comparison on a 512 MB Vps http://www.cpanel.net/products/cpanelwhm/vps-optimized.html

Just really depends on how busy the sites are. If it is just static pages with no php you will get a lot more on. One WP or VB site can easily fill a 512mb VPS though.

you could optimize all of your settings for mysql etc...
and have the server serve many sites (depending on size and all that)

Depending on your clients traffic, no matter if you have got 1000 clients in your VPS if non of them are active you are still good to go :)

some thing here but i have 1024MB RAM
and 1024 MB Burstable RAM from sitevalley :)

i have 15 clients using Wordpress Low traffic low Bandiwdth just 1,2 GB
and 5 to 8 clients using Clipbucket (youtube clone) Monthly Bandwidth is near 8,10 GB from all Video sites is it good to run on 1024 MB ram??

i have 20+ clients using simple html or php but static websites

Depend on your Script how much resource that use but i think you can settle 50 clients easily ;)

I used my Own coded CMS and i get 50 k Unique hits a day and it was working smooth and loading was fast.

at a time 200 to 500 Users online at same time but not face any issue :) on VPS server with Hostgator and servint as well knowhost.

Well I do not suggest running a shared host on VPS with 512RAM
coz if even 15 clients have forums or wordpress or any database related websites with good traffic, mysql will eat all RAM.

and if even 1 will get ddos, your down...

But if everything is perfect(its never perfect) you can host 50-70 websites

or use low memory mysql config's (so it uses 50MB about) and then see how many clients till' it slows down.

A huge factor in this would be your host node - If it's overloaded, your I/O speed could be unbearable and unsuitable for any production websites.
Inadequate CPU resources could also play a part as well.

Try looking up some load-testing services like LoadImpact, they might be able to give you a more realistic indication.

When you optimizing your server, you will get more free memory. I have a clients have about 50 websites with CPanel, and they used 786MB Ram, I think you will not believe me. :D

It's depends how you can manage and optimize your server, when you do that as what you need, you will get a difference performance, to the best performance sure. :cool:

I had this on a 512mb VPS before I upgraded to a 1GB because I thought I may have a medium traffic forum but left it since the price was right and you can never have enough RAM. All of these are low to medium traffic Wordpress blogs.

Depending on your clients traffic, no matter if you have got 1000 clients in your VPS if non of them are active you are still good to go :)

This. You theoretically could have as many websites on it as you want, but it depends where the traffic is going to. Are you going to be hosting websites that encounter a lot of traffic?

Hi,

Well as many of the OP told you it depends on the amount of the resources you will use.

For example lets take Wordpress, its the most commo script being installed now days. And its easy but for the server (in your case the VPS) it take a loot of memory/processes.

1 Factor is the scripts and the processes your client do.
2 is the Databases, you need to tune up my.cnf in /etc/ . In best case i was suggesting an remote mysql, a server dedicated to mysql as the processes in the sql will eat 1/3 of the memory in the vps.
3 is the scripts you use in the vps, CSF, bruteforc detecter etc this all eat memories so be careful.

So on putty watch the "top" fuction to see if your vps can handle it if yes = put more clients if not = do some cleaning see who is eating a loot of memories etc..

it depends on how much your clients use the bandwidth. I have a client who uses 1Mbps so i dedicated for him.

On an average ,you should host not more than 350 users on VPS for optimat result.yet ,if no/minimum traffic,then you can go with 1000 users

Ah, but I think the good thing about VPS is the marginal cost for increased RAM/ bandwidth and Storage is not a lot, so as you grow you'll make more money and the resource hogging sites with level out.

Not a bad way to grow.

i think 15 client

the exact number depends on the nature of your websites. heavy sites take up more space, such as social or interactive websites, since they require user friendly components. for maximum number of user, get some low traffic websites

You can have unlimited sites, unlimited email, unlimited databases and unlimited domains, just so long as you have limited disk space. Just ask most of the hosting experts here.

The answer is always 42.

It depends on what kind of software-solution you are planning to use. nginx and such could probably deal with this

You have to love responses like:

"I think 15 client"

Please tell me you dont host customers :)

I have 90 accounts on a 1GB VPS. Memory usage is only half. Averages around 500-550MB. Control panel is cPanel.

About 75 accounts use wordpress. Average hits per account per day amount to 30-40 page views. Guess its enough because the pageviews aren't much.

Its hard to say the exact amount of customers you can host, it really depends on the sites there hosting.

The answer is always 42.

And Walmart is ALWAYS on the left ;)

All kidding aside, the answer I quoted above is about as accurate as any I've read in this entire thread - they're all WRONG!

If anyone answering the questions above is truly flying by the seat of their pants like that... Well I want to meet their disgruntled, or at the very least naive and ignorant customers.

No one above has stated the obvious, and prudent answer the OP should have gotten.

1.) Install snmp and zabbix agents on your server and monitor your box!

2.) Read your log files. By the way, you're not going to see any of those dreaded, "MySQL went away" errors resulting from a lack of resources if all of the sites have nothing but static HTML.

That's the only way you're going to be able to gauge the utilization of your resources. Monitor, Monitor, Monitor, and project.

Your consumed resources are also going to vary on a predictable trend depending upon the time of day, day of the week, etc.

Are people posting those kinds of answers because they just don't know any better and want to post?

The answer once again is, "Monitor your machine, and you'll know".

Zabbix, Nagios, Cacti, ntop, bmon, wireshark, mrtg, whatever. It's all good and gives you different perspectives. And don't forget to read your logs!

I hope that helps. I know that none of the other posts above did.

Kindest regards,

There are hundreds of hosts here who have together monitored thousands of servers. Plenty of emprical data to make an educated estimate. Same goes for any single host that has managed at least a few servers. Experience can answer the OPs question.

You're absolutely right. 42, between 0 and 1000, 15, and other nebulous offerings certainly demonstrate that experience.

No. One should not depend upon guestimates. One should watch the consumption of their resources, monitor what's going on, and responsibly administer the machine in the best interests of their customers.

One irc script kiddie or one minecraft server installed on that wimpy little box would bring it to its knees, and the OP wouldn't even know why - because he's not monitoring and projecting usage.

Your notion is ridiculous.

I hope that helps :)

Kinda off-topic

If your ready to move on, why not just invest some money in some hardware ($1000-$2000) and colo the server for pennies. Then you would not need to worry about a VPS and how many clients it can fit. Plus you'd have much more room to grow.

My two cents.

On-Topic

At most 50 clients (If you getting 3-5 PHP/MySQL req/s) other then that, static files don't use much. You could grow.

How many clients you fit in a VPS depends on their usage and other factors. I would suggest you install Litespeed however so that you can host more customers on the VPS.

So your answer is 1?

How many servers do you have, what kind are they and what is the average number of sites on them? The answer to that is what the OP is seeking. Not whether to monitor or not.

When I was hosting with win2003 servers I was able to put 1100 sites on them with database and email on their own dedicated servers. So if someone asks me how many sites can they put on a similar server I can safely say "about 1000."

How to get to 1000 is a different question. The non answer you give is just evasion.

Are we turning this into the proverbial 'how many angels can dance on the head of a pin'?

I think one from experience can give a good guestimate. To follow your logic he would be able to find out by physically running the sites anyway.

But I think a valid guestimate using some proviso's is perfectly valid and acceptable.

Can you tell us your company name so we can all avoid it?
