An Overview of Scalable Hosting
In today’s web environment you never know when there’s going to be high user traffic to your website; if your site can’t cope with a surge in traffic then your website can load slowly or not load at all, meaning lost visitors and potentially sales. In fact, sometimes dealing with success on the web can be just as challenging as dealing with failure. Today scalable hosting provides a cost effective solution to this problem.
Scaling refers to the ability of a system to grow when the scope of the processing required increases (in this case, serving pages to visitors of a website). Scalability today is a measure of a how well a system can provide resources in an on-demand environment.
This means providing resources on a self-service basis in near real time without the user having to design a system that can cope with peak loads. This is sometimes referred to as elastic hosting because it expands to fit processing requirements.
Increasing the capacity of a system is done by providing more of the same hardware and software (usually called horizontal scaling) to share the processing load and is regarded as the best form of scalability. However, horizontal scaling can be expensive to implement in-house and often the added resources are only required during peak periods.
Many companies are turning to scalable hosting providers who, because of the large data centers they maintain, can easily scale a user’s processing requirements as needed. This provides a cost effective method for dealing with peak or increased loads since the company has access to a large processing pool but only pays for what it uses. Scalable hosting providers often maintain large numbers of servers at different locations over multiple internet connections with massive redundancy so that if a system fails it is immediately replaced with another. This means that wherever your visitors are, your website will always load reliably and quickly.
