We use Softlayer and Liquidweb for all of our production servers. None of them is really a budget server provider. Softlayer does sell some budget servers which are not at all good for production servers planned for web hosting services due to their inability to upgrade in future (Like xpress servers). Moreover the price isn’t really right for the same set of hardwares with some other budget provider. We have been using budget servers for our backup servers which usually can hold tons of TBs of data.
