As online companies have multiplied, web hosting for these websites has become very mission critical.
This is because if these websites would go offline or perform inadequately, it would cost a lot for the online company.
It could mean lost revenue, damaged reputation for the company, as well as loyal customers lost.
Companies that offer online gaming and betting have even more stern requirements since they have to provide a response, which would be guaranteed in near real time.
Events on sports betting also have a crowding effect from all the business that need to handled in condensed time windows.
These companies would need hosting that would definitely require more than the simple provision of features and services by a regular web host.
The host should be able to provide the bandwidth and server quality in terms of the host's CPU's processing abilities, RAM quantity, hard disk space and the durability of the components, as well as the available power supply.
With an application that is designed to be internally used within a company, an individual could always just put the limit on the maximum number of persons who could use the application.
This number could be unpredictable, as it could grow rather quickly.
The traditional approach would be to vertically scale up, increasing the CPU's speeds, bandwidth, memory and others.
There would be a limit, however, as to how far this could be taken and with a lot that depends on such a resource concentration, a failure would most probably be nothing less than catastrophic.
What needs to be done would be to achieve horizontal scalability using a distributed architecture.
This would not only allow an increased scalability, but would also create reliance to the failures and faults that are within the system.
And also, this model would inherently be suitable to most services and operations, which are offered online, that are quite simple.
