In a Quest to Load the Servers

When I was active in Indyahozting, I was too much worried about server loads. Because it was something that affected all clients, and I hated it when servers crossed a total usage of 75%, which would make all sites on the server slow. There were not much of a problem on the Linux servers, but Windows servers always used to give me a hard time.

Right now, Im in a quest to make all my automated blogs work in full effecienty. I was hosting them on a shared hosting account, but now I have taken a dedicated server from iweb where all those blogs are hosted. And I am amusing myself in finding that the server is running at full effecienty, and that all the pho sites are always busy updating the blogs with articles round the clock, and serving the search engine visitors. The network lines are always busy, and the server’s processor is always at about 90%, and the memory usage is at 1.8 gb out of the 2 GB that it has got.

I dont believe in loading the hard disk though, since that would naturally slow down the server with lots of data. So I have dedicated one disk for the databases alone, and one for the files and logs and stuff. All of them are wordpress sites, and wordpress sites only work with databases a lot, so the 2nd hard drive for sure is getting a lot of work for itself. And a backup of the 2nd drive is constantly being taken in the first drive.

I am worried only about the databases since the php is the same for all the 85 sites that the server hosts, and they all use the very same wordpress templates. So if that is lost nothing is lost. If the databases are lost something is lost, and never is everything lost, since all the site sites that are hosted on the server are automated and get updated by themselves.

Gmail Updates

I woke up in the morning, and the first thing that I always do when I get is up turn on my computer or laptop and only after that go wash my face, and come back to see the computer booted and i login and check my mails first. The mails are my life line, 2nd to mobile phones.

But Im not with mobile phones these days much. Not talking a lot, and I have asked everyone to mail me only, and not to bug me over phone. Im on vacation for God’s sake.

So, this morning when I logged into my gmail account, I noticed a few changes. Since im into various activities, and my gmail is the only contact point for all, I guess I should be the only user of gmail having the largest number of message filters, about 250 of them, and about 40 labels on the sides, where the important mails get filtered into and skip the inbox, and unwanted mails such as jaxter invitations, orkut friend requests everything goes into the trash can automatically, and never make it to the inbox.

This monring, I saw that the labels had a small box on their right side, and when I opened mails from these labels, the name of the label appeared below the subject of the mail, and when I clicked on it, it just took me to the page where all mails in that label were listed.

Then when I clicked on the box on the right of the label in the left menu of the mail, it gave me options to color the label, and when I chose a color to the label, in the all mail view, all labels were highlighted with the color that I had chosen, and it made it a lot more easier to spot the mails. Earlier, thanks to my bad eye sight, I had to look closely to read what the label is. Now, that part has become easier. Reading the subject line of the from address has nto been a problem for me yet.

And, after all these, google is still in beta.

Server Vitrualization

A fully dedicated server has got a lot of resources that it can be shared amoung so many sites. But certain clients do not wish to let their sites bein a shared environment where others can overload, and that overload can affect your site, and your downtime could nto be compensated easily by anything.

But at the same time, they might find a dedicated server for a few sites that they have to be quite expensive, and that they might not need so much of resources. What do they do? They go to virtual servers.

You buy a server, and a Virtuozzo or a Xen license, install it on your OS, and you have your virtual serers on a dedicated server ready You can have as many virtual servers as your operating system permits. In linux, it is virtually unlimited, and you can create as many virutal enviromnets as you like, but a windows server has got its limitations. It also, does depend on your license.

You could go for openvz for linux, the open source server virtualization software, and since it doesnt come with any licnese fee, it would cost you a lot less, though that gain would vanish away when you employ specialists in that line of server administration.

You can set the Processor, Memory and hard drive resources, and unlike in a shared environment, you will have these resources always on the standby for you, and no one else would be using it, even if its being unused. So, virtually, except for its physical configurations, it is a dedicated server.

Various applications of server virtualization will follow this article soon.
