For a popular wordpress powered blog you need PHP virtual private server or dedicated private server. Dreamhost dedicated server and virtual private server are great choices for growing blogs. We also use Dreamhost virtual private server hosting and we have published this website host review earlier. Dreamhost hosting is reliable. Dreamhost VPS has been powerful virtual private server for our wordpress blogs. Private web server allows you to expand resources as your blog demands. Private server hosting is not cheap so it should be managed by you at regular basis according to your website/blog needs otherwise you will have to pay extra bucks every month that your website never used. Dreamhost shared server is also powerful enough to bear a blog’s load. When you need performance and there comes a phase when your blog attracts hundreds of users at the same time, then you need to shift towards VPS hosting or PS hosting where you can scale resources as you need. Dreamhost offered a slider to increase or decrease resources of PS as you need them which also affected at monthly costs. In Dreamhost Panel there was no indication or alert of exact resources blog uses at that specific time except for a graph. Then Dreamhost changed their system and things became a bit dodgy. We had to always keep slider a little more than the graph measurements. On asking they said that some portion of resources (swap) is needed by the system that is why you need to keep it a little bit higher than the graph details. Now they have modified the system and its good to find improvement in how we can manage our PS resources.
