Aug 24, 2008Not sure where this belonged so put it in web hosting as it could cover dedicated, colo or shared.
In a couple of months I am going to be launching a new e-commerce website for the company I work for, so it is absolutely vital that the website never goes offline, otherwise I will be in deep ****.
It will be hosted on a server that has been built to be very redundant; 2x Hotswappable Redundant PSU, 4x Hotswappable HDDs (RAID 6), Redundant NIC.
Sods law though to achieve this redundancy it will need to be on a colocated server, so if there is a major problem like the motherboard dying, then I will have to get down to the DC (3 hours away) and replace the entire server. Which wouldn't be practical as we would need a replacement server, all setup and ready to go, to do that.
Also, if there is a problem with the data centre itself, then we would be stuck until it is resolved. I have hosted sites with data centres in the past that experienced power or network problems which sent the sites down and it was totally out of our control to either prevent the downtime or restore the sites.
So to increase redundancy, and minimise downtime, I was thinking of load balancing between two servers. But then I assume they would both have to be hosted in the same data centre.
I was also thinking of having the site hosted on the server, but having some shared hosting (or a cheap dedi) ready to go just to fall back on if the server goes down. That way I can forward requests to the shared hosting as a temporary measure whilst the main server is restored. But the problem with that is I would probably need to get another SSL certificate. I would need to get the payment gateway provider (protx) to change the settings for the IP of the shared hosting, which knowing them will take 72 hours to process.
Budget really isn't an issue here if it can be justified, just looking for some ideas at this stage. There is no way this site can be down for a second longer than it needs to be.

View 5 Replies View RelatedApache Memory Usage, Why So Different On 2 VPSs
Mar 24, 2009I currently have 2 VPSs that I'm monitoring and I noticed that on one of them the memory usage is much higher than the other which doesn't make sense to me. I tracked the high memory usage to the Apache processes.
Here's the overview of the VPSs:
LiquidWeb VPS- 512MB RAM, 10 Sites with minimal usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 1.2 /usr/local/apache/bin/httpd -k start -DSSL
Virpus VPS- 384MB RAM, 61 sites with moderate usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 0.3 /usr/local/apache/bin/httpd -k start -DSSL
Both Apache configurations are identical, the only difference besides the hardware is that LiquidWeb runs CentOS4.7 and Virpus runs CentOS5.2, any ideas? It's not to big of a deal since I'm not near my limit for either of them but I was just curious.
[Powervps] Older VPSs Are Better Then Newest
Aug 7, 2007what's going inside my provider Powervps/Defender hosting, they are offering now 25% OFF of new customers + triply bandwidth.
Curent customers are not allowod to get this offer, until they order a new VPS and cancel the older.
I'm asking, because i feel, it's samething, why they don't go upgarading the account throughly with keeping IPs and data..? why do old customers need to cancel the old VPS then they go get a new VPS..?
are Old VPSs powerfully then the newest..? any informations...?

How To Use 2 Windows VPSs For Higher Reliability
Oct 3, 2007In order to increase the reliability of a audio streaming service I am thinking to take the action I describe below.
1. Buy two Windows VPSs with WMS installed.
2. Register a domain name (i.e audiostream.com) with 4 nameservers: ns1.ip1_vps1, ns2.ip2_vps1, ns3.ip1_vps2, ns4.ip2_vps2.
3. Create all publishing points (streams) on both servers.
Normaly VPS1 should serve all clients. In case VPS1 goes down, VPS2 should jump in and serve all clients-connections. As soon as VPS1 becomes available (ns1 & ns2 start responding again), VPS1 starts serving all new connections.
Load balancing or any other kind of advanced load, traffic, etc management is not important.
Then we have the following cases:
1. VPS1 is down , which means that VPS2 should take charge.
2. VPS1 is up (ns, http, ftp services), but WMS1 is down (crashed). Means that the playlist (asx) file should be built so that it also includes the IP, port & publishing points of VPS2. This should be done because ns1 & ns2 will answer without any problem, but WMS1 will be crashed and won't serve any media connections, thus ASX will look for the next available stream in the playlist.
Do you think that the above is possible. Is this gonna work?

Xenvz Stop My 2 VPSs, Because I Spread Conficker Virus?
Oct 13, 2009Last month I order 2 Xen VPSs from Xenvz.co.uk and use them for VPN proxy.
But a few days ago, xenvz stopped one vps and state "This is because it is spreading the Conficker virus.". I'm a little surprise because there's only 10+ users on this vps. Most of them use VPN for visting Youtube or P2P download or gaming. And Conficker virus can only run on Windows, but all my vps is running on Debian.
Maybe someone had download something that contain Conficker virus?
Anyway, I had to move a few users to another vps yesterday.
But xenvz stop my another vps today for the same reason!
I really do not know whether or not one of my user is spreading or other reason, but as I know, Conficker virus had affected thousands of hosts in the past. If someone download or being affect by conficker for any reason, provider then stop their host, I'm afraid thousands of sites would down.
"Burstable" RAM In VPSs
Jan 28, 2008Most VPS offerings have "burstable" memory allocations. I get how you can do this with most things -- letting a VPS access more CPU cycles can be done pretty easily, and a 10 Mbps line burstable to 100 Mbps makes sense.
But how does the guest OS handle all of a sudden having more memory? Since a lot of VPS guests run without modification, how does this work? Does the typical Linux system support dynamic changes in RAM? I can only imagine that dealing with "un-bursting" is even more complex: suppose I have 128MB, burst to 512, but then the host node tries to reclaim some of it. Is the system smart enough to seamlessly swap out to disk when RAM "disappears?" I'd fully expect a kernel panic when the system's RAM shrinks in size, particularly when the RAM was in use.
I'm curious about exactly how all of this is managed. Given that 95% of VPS hosts give a burstable range of RAM, what exactly manages this? Is the virtualization platform handling this and somehow "tricking" the kernel, or is the guest system able to deal with changing RAM allocations? And, if the latter, is this a standard feature of the Linux kernel, or are guest OS mods still necessary to deal with burstable RAM?
