Would I still need an onsite IT manager if I use cloud hosting?

There is no need for an onsite IT manager if you are using cloud hosting. Cloud computing ISP one that better than current providers. ISP-Redundancy: Contoso can have Internet access even if the current ISP provider is down.To accomplish this, another Internet path will be necessary, usually via another ISP.

Integrated Network Load Balancing (NLB): By integrating NLB with Forefront TMG, you can not only load traffic among NLB nodes, but also ensure a successful handoff between one node to the other, should one go down. Cloud computing ISP is faster than current providers. Sometimes there's a cheaper local alternative for high-speed internet access.

More Secure: Exchange Online services include antivirus and anti-spam features. Still, Contoso wants to ensure its users are protected when browsing sites originated by the e-mail system, so it’s using a multilayered approach.So you will get less trouble in cloud computing ISP than current providers. In case of someone onsite to work with your computer network, is totally depends on you.

If you are familiar with your computer network then there is no need for someone onsite to work with your computer network but If you are not then I think there is no need to take a risk for your computer network.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
