Mosso has been the pioneer of Cloud Hosting. One and a half year after the acquisition of Mosso by RackSpace, RackSpace has finally come out with its own branded cloud hosting based on what Mosso has achieved: RackSpace Cloud.

You can find a slightly more detailed report at here. Should you want to know more, here’s some Mosso and RackSpace cloud reviews and a cloud sites coupon code: (Code Hidden) you can use to sign up with the cloud sites plan for $25 off.

Change and Increase the Max PHP File Uploading Limit

The default php configuration comes with a hard cap of 2MB on the size of uploaded file determined by the php.ini directive upload_max_filesize in conjunction with post_max_size. The maximum uploading size of a file is the lower. Therefore, to increase the uploading cap and raise uploading limit, you will need to edit those 2 directives in php.ini.

The location of php.ini varies distribution by distribution, in this example, with Ubuntu 9.04 Jaunty, php.ini is located at /etc/php5/apache2/php.ini, so

sudo vi /etc/php5/apache2/php.ini

Press / to find upload_max_filesize and change it to, say 8M:

upload_max_filesize = 8M

Press ESC, :, wq and Enter. Now the php.ini is saved with the new uploading file limit. Reload apache2 to read the new configurations:

sudo /etc/init.d/apache2 reload

Now you should be able to upload any file up to 8MB in size, in case you need larger uploading limit, in addition to change upload_max_filesize to, say, 16M, you must also edit post_max_size to more than or equaling to 16M because file uploads are processed through HTTP POST method.

Best Linux Server Administration Books for Learning Linux

In the web hosting industry, Linux is undoubtedly the No. 1 server OS that has been used and talked about. With so many differently branded distributions such as Ubuntu, Debian and CentOS, the basic part has always been the same – the file system, the open source packages, the commands, the shell programming and so forth. It’s a hard nut to crack, but with a few good guides and books, you will soon be on your way of becoming a professional server administration.

How to know the physical location of a website domain or tell where a site is hosted?

To trace and know where a website is hosted physically (server location), you will first get its IP address and then query it for the geo location. Many online tools and IP databases offer such free services such as IP to Location. It not only converts the IP to a physical location but also tries to give the institution (companies, data centers, national organizations, etc.) that’s responsible for the IP address based on IP ranges distribution table with an option to map the IP geographically.

Oh wait, I think I forget about how to get the IP address of a website. All after all, you can ping the domain name to get the IP address of the site from command line. Or, you can use domain IP lookup tools such as this one. It not only gives you the IP address of the particular domain URL but also pokes the server around and guesses what other sites are possibly being hosted on that IP.

Actually, there’s a much simpler one to consult when you need to know the physical location of a site and where the website is hosted: Domain Tools. By querying a domain, it gives you the IP where the domain / site is currently hosted and also the organization or data center (might be a hosting company) that’s administering the IP. Very good tool to know where a site or domain is hosted.

A Review of RackSpace Review

Disclaimer: I’ve never been with RackSpace (but the cloud hosting, Rackspace Cloud) hosting and everything is taken as it is from this review at WHT. I’m just a little surprised that a host like RackSpace could ever make such a mistake to introduce 8 hours of downtime to its clients (that is of course, if what the reviewer said was truth and precise).

The original RackSpace review can be found here. I tried to reply to the post but it is too old.

But pardon me, 8 hours of downtime? Whatever the reason it is and no matter how many times the CEO apologizes for this (it could very well be an employee who is assigned the job to apologize on behalf of the CEO or automated mass email), it’s simply unacceptable. I don’t know about the other sites you may have with them, but officedebo.com doesn’t seem to be a mission critical one with tons of traffic that’s probably making a dollar every second. If that is the case I doubt you will remain calm about the 8 hours downtime.

8 hours downtime is even barely acceptable for other hosting companies, let alone RackSpace, it’s absolutely way too MANY for a host like them. Support comes far second to uptime, no matter how good it is.

Imagine if there’s a host that can Godly guarantees all of your sites 120% uptime but with no support at all, will you pay as much as what rackspace charges you for it? I think the answer is pretty obvious.

Again, I’m just talking about the issue here as it is from the original reviewer. 8 hours downtime is indeed unacceptable however personally, this incident hardly sways my belief in RackSpace. They are still one of the top hosting providers out there that’s worth your trust. View more reviews of Rackspace.

Also, for Rackspace Cloud, their newly launched cloud hosting service, here are some customer reviews.

What is Cloud Hosting & Cloud Computing? Definition of Cloud Web Hosting Defined

how cloud computing worksCloud computing has been the latest buzz word ever since last year 2008, promoted by large Information Technology companies such as Google, Microsoft and IBM. It’s very similar in nature to grid computing (An alignment of individual computers serve virtually as a single one, providing combined computing resources) though more focused on the way of consumption rather than the infrastructure itself.

The biggest Cloud is the Internet itself. It is a form of computing that supplies resources as a service to the consumers (enterprises or individuals) and that is paid for in the manner of utility such as electricity. This way, traditional sunk cost of building a huge self-supporting IT infrastructure can be avoided and users only pay for what they use as they go and exit freely. The actual physical infrastructure is created and managed by experienced hands who run and support it as well as the computing buyers.

It’s much like the on demand allocation of computing resources such as CPU time, network capabilities and digital storage with flexibility in scaling. The whole system frees the users from learning and managing all this stuff.

Cloud hosting, or cloud web hosting, similarly, backed by large clouds of computing devices or a cluster of servers, supplies hosting resources such as data storage, network bandwidth and CPU usage and bills the customer in the way of utility. With a cloud host, we only pay what we use and never have to worry about how this cloud stuff is accomplished in the back stage. We don’t have to worry about any of the technical aspects such as load balance and security, nor the hardware performance (CPU, RAM, hard drive, etc.), nor the chores such as device repair or replacement. We just consume and enjoy the results – the hosting resources – and use them to feed our websites and applications.

In simple words, any of the websites hosted on a hosting cloud or cloud based hosting should have the potential to spread its computing needs across the entire cloud, introducing the following benefits:

  1. Instantly available resources from the pool (not restricted by any single physical server at all) to be allocated to where it’s most needed.
  2. High scalability enables easy and fast scaling in resource consumption, either manually or automatically.
  3. Sudden website usage surge will not be a problem at all because the burden is evenly spread across the entire network.
  4. High availability and great reduced failure risk because the cloud works as a whole and any integral piece of hardware in it is dispensable. The failure of any one of them will not affect any of the hosted websites at all.

One of the most prominent players in the current cloud hosting market is Rackspace Cloud.
