Everyone knows that servers and computer systems host the websites and blogs that they operate.
Of course, these machines have the power to beam data onto people’s screens. And, they can do it all the time.
So, just how do these systems keep up and running?

Any digital system like this is almost guaranteed to have flaws at some point during its operation.
In reality, a complex array of mechanisms is used to make sure that your website never goes down. And, this post is going to go through some of the most important ones.
All of the data that flies around inside a server or a regular computer is transmitted with either electricity or light.
For the most part, electricity is used for this job. And, when light is used, it still takes power to generate the light.
Without this resource, servers are useless. So, when the power goes down, the machines will go down with it.

Of course, this is something data-center owners have had to think about. And, it’s where a UPS comes in.
UPS stands for uninterruptible power supply.
It’s a unit that sits in the server, controlling the distribution of power. When power dies, the UPS will have a couple of tricks up its sleeve.
First, a battery will kick in. This battery will be drained very quickly, though. So, during this time, the operators will be getting a generator ready.
Once the generator is running, everything stays up until power is properly restored.
When large amounts of power are used, heat tends to be generated. The processors and other components in a server tend to use more power than their consumer equivalents.
And, the chassis that they sit in aren’t necessarily designed for perfect cooling conditions. So, these rooms get very hot.
Heat causes thermal throttling, which lowers the speed and efficiency of a device. And, it can even damage electronics if it gets too bad.

Air cooling is a great option. But, it has a massive floor. It dumps all of the hot air outside of the server. But, that heats up the air that it’s sucking in. So, air cooling will eventually stop working.
This is where adiabatic data center cooling comes in. This sort of cooling involves water being sprayed onto coils that are used to take away the heat.
When the water makes contact with the coils, it evaporates; causing a natural cooling phenomenon.
Of course, one of the best ways to make sure that you don’t run out of servers is having too many servers, to begin with.
This way, if one server fails, another can take the job over. This practice is known as redundancy. And, it goes down to the smallest components of the server.

Even things like hard drives will often be installed with some going spare. This is a great way to make sure that a server never runs out of resources. And, it’s also great if hardware decides to die when you need it the most.
Hopefully, this will give you a greater appreciation for the work that your web host does.
When you have your own site, it’s easy to see all of the work as your own. But, there’s a lot that goes on behind the scenes that people don’t know about.
Servers are difficult machines to work with. And, as such, they require a lot of care and attention.
