Web optimizations - part 2 - Why would I need a cluster?

Posted in

If you've reached this page, you're probably either curios about what other people think about server clusters or you think you need one.

So the question is 'Why would i need a cluster?' . I am going to answer it from our field of work. What we do is manage large server solutions for high traffic websites. Website delivery speed plays an extremely important factor in user experience while navigating a site. No matter how powerful a server is, it will eventually create bottlenecks when being hit by a large number of users. The limit of good behavior depends on several factors such as server power, website optimization, network bandwidth attached to the server, ram amount, etc. Whenever one or more of these factors is abused, the server will start to show slowdowns or even become unreachable.

Web optimizations - part 1 - What is a cluster?

I'm not going to talk about a star cluster obviously, (although I'd like that :) ) but about a server cluster. Basically we're talking about a bunch of servers that work together to perform certain tasks.

These tasks can vary from doing file operations, running databases, to doing some sort of complex math calculations.

Web optimizations - cluster solution needed?

Ok, this is a very wide topic but I will try to touch some corners in the event somebody will need such ideas. This will be a series of articles that I will write as time permits.

What will be covered in these series:
