I am just curious about the size of business of hosting, especially , dedicated server market. Trends are shifting to VPS in my point of view. However, I think the dedicated servers are still in position in the market now.
I think it has slightly diminished after the widespread of VPS's. There's a much bigger market for VPS's than there is for dedicated servers.
The servers are more powerful than few years ago, so I guess there are less people that needs a full server. Cloud hosting is currently getting more and more popularity.
right now, its the trend for cloud hosting, and even cloud dedicated server hosting. Private server is leaving the market and some web hosts that i know are no longer upgrading their old server and offered the existing private server.
Dedicated server market is not so popular as clod hosting and VPS, but it's relevant for some specific target audience - those who have some programs, networks, big scale e-shops, etc. But if you're interested in launching some company in this niche, you should consider the full complex of services - cloud hosting, VPS, VDS, maybe domains. It's not relevant to consider only VDS.
