Businesses invest a great deal of money into dedicated servers. What may start with one server and a few gigabytes of data can eventually grow into an entire server cluster with several petabytes of data. Ideally, a hosting or colocation provider will give businesses the tools to smoothly transition from one stage of development to […]
Your shared hosting account has probably served you well for quite some time, but there comes a time when it might be a good idea to upgrade your website(s) to a dedicated hosting plan.
