VPS types, pros and cons for usage
Hi I am new to VPS. I am looking to get one because I want more flexibility in what my online services (currently I only have a website hosted with siteground.com) offer me.
I have been looking at a number of different providers, what I've seen now is that there are usually VZ and KVM plans, and they both have SSD and SSD-Cached in each type.
I am hoping to use the VPS for a website, VPN and maybe owncloud if possible, so of the different types of plans would I see much of a performance difference between the types, especially for the VPN ability?
Other questions I have are:
Can I run two websites from one VPS? (2 domain names)
Do I have to configure my own email server on a VPS, or is it set up for me? (use my own domain for email)
Is it difficult to change VPS provider once you are set up? Can you do like a disk image download and load it up at another provider? Is it a big hassle to move?
