When choosing a managed hosting provider there are many things to consider. Different people have differing criteria as to what constitutes a good host, and different areas of hosting will be important to each prospective client.

There are many different types of managed hosting. Some are fully managed with everything taken care of for clients, while others are only partly managed. This means some parts of the hosting are managed while others are not. It is therefore important that you know what you are getting for your money. You don’t want to think that you are getting a fully managed service only to realise that you have to perform a lot of the hosting tasks yourself. People and companies have different interpretations on the definition of managed hosting so make sure you don’t assume something is included without having it confirmed.

When choosing a managed hosting provider it is best to focus on the areas that are most important to you. Everyone’s requirements are different so you need to find a host that performs well in the areas that suit your specific needs.

Bandwidth is one of the most important factors to many. Not having enough bandwidth could be problematic for large sites or if you have many visitors. So you need to be sure you have enough bandwidth for your needs. At the same time you don’t want to pay for unnecessary bandwidth as this will obviously drive up the costs. Of course you want some extra bandwidth in case it is needed unexpectedly. It is a similar principle when it comes to support. Not enough support could be an issue if you come into problems but you don’t want to pay for support that you are unlikely to use. If you have knowledge in hosting you may not want certain areas covered, but then you might not want the hassle of this. It may be important that the servers are monitored so any problems can be spotted.

You might want to consider the expertise of the managed hosting provider’s staff. After all, they are looking after the hosting of your website so they should know what they are doing. The experience of the host might also be something to consider, for example how long they have been in the business and how many clients they have had.

As we are all becoming more conscious of our environment, the demand for green web hosting has considerably been on the increase. This increase in the demand for green hosting is as a result of the awareness campaign being carried on different platforms on the use of electricity and its impact on the environment. The government’s directives on the adoption of green technologies are also a considerable factor towards the increase in green hosting demands.

It is a fact that every hosting company and ISP in America should be powered by a third of the yearly ancient Seabrook nuclear reactor production. But this is not happening now. Undisclosed sources has it that out of the over 1.4 trillion KWH of electricity generated in USA within the first 8 moths in 2009, hosting companies consumed close to 4% of that generated power. Hosting companies are reported to collectively spend an average of three billion dollar yearly on electricity. This amount of money can be used to boost other services on the internet if there is a way to curtail the electricity expense. The Department of energy reported recently, that 9.79 cents is the average cost per kilowatt in the whole of USA. These points are pointing towards the economic importance of finding ways to reduces electricity consumption of the hosting companies through green hosting.

Without downplaying the role of green hosting companies, it is good to note that there are some various differing reports on some eco conscious websites. Some of them are of the opinion that there is no significant effect the consumption or usage of bandwidth has on the ecosystem. This may be a slight disservice to not just the consumer but also to the environmental-conscious parties who are campaigning for safer environment. Their claims are supported by numerous data that can easily be accessible.

Moving from a green-compliant industry to an eco-friendly net energy producer is an achievable feat for the various preachers of green hosting. Their goal of becoming carbon-neutral business enterprises is worth emulating too. Green hosting is a very welcome idea.

When you look at the CPU activity of your computer, one of the parameters is the iowait. This value shows how much time your CPU wastes while it is waiting for I/O operations for complete. These include disk read/write operations, network, IPC, etc. Is this behavior a problem and, if so, what causes it and how to fix it? One one of the popular Unix-related forums one “genius” wrote:

The iowait “problem” is funny. It’s like when people complain that Linux is “using all my memory”. Yeah, no shit. You should be upset if you are copying files and your computer is /not/ in 100% iowait.

In reality, 100% iowait indicates that there is a problem and in most cases – a big problem that may even lead to data loss. Essentially, there is a bottleneck somewhere in the system. Maybe one of your disks is getting ready to die; or, perhaps, the NIC firmware is having problems with the latest kernel upgrade you installed. The troubleshooting process starts with the potentially more serious possibility: bad disk.

Take a quick look at /etc/messages, /etc/dmesg, /etc/boot.log and any other system log files. You are looking for disk I/O errors, failed read/write operations, bad sectors – anything that indicates a hardware problem with a disk. If you don’t find anything, look for IRQ and disk controller errors. Also look for memory errors and kernel panics. The three most likely culprits of high iowait are: bad disk, faulty memory and network problems.
