What is Dedicated Server Hosting?
Today to talk about what is a dedicated host? Dedicated host is a construct that you see a lot in the world of cloud. But it's a little confusing what does this dedicated hosting. Actually mean why does it look like it's so expensive. when you compare it to buying a dedicated instance or just a normal virtual server and the answer is dedicated hosts are a way to provide single Tenancy. Single tenancy means that no one else can run on the compute that you are running on.
So if we think about a physical cloud host right. we've got our actual cloud server here. This is the actual host that runs in the data center in a normal multi-tenant environment. we would take and we would divide that host up into pieces and every one of these pieces is a virtual server, that you would buy right. I'll just mark that as VSI in a dedicated host. we still have the same host that same box that we were talking about before. But instead this is your box and you control all of the VSIS that schedule on to it.
How does Dedicated Server Hosting work?
this is all yours and so you can choose to divide it up however you want you can have one third of it. go into one VSI and two thirds go into another. you can divide it half and half or you can put lots of little bitty ones on it and so the question of course always becomes why would i do this.
What is the value of a dedicated host?
why would I purchase this thing and the answer is really twofold first is that single tendency that i mentioned before single tendency means that you don't have to worry about anybody else being able to crash through the hypervisor layer within this host.

it's already incredibly secured in the world of cloud. it's just one more layer of protection. this is very important for healthcare workloads folks in banking and finance like that but in addition to that single tenancy it also allows you to schedule workloads that want to be close to be each other close to each other so. If we think our of our example here, where we have got two VISI of the same size? let's imagine a high performance compute workload something that in the world of hpc. where you have lots of compute working on the same problem in order to minimize latency and maximize performance.

Why would I purchase dedicated host?
you want to pack these onto as few physical hosts as possible. because data transit through a physical host is much faster than data that goes across the network. if we think about our example over here. where we've got our multi-tenancy and we've got multiple multi-tenant boxes. every one of these has to link together and that link together takes time. there is a latency penalty that you pay but in a dedicated host like we have over on this side.
Because these all run on the same physical box. you don't incur that latency penalty and you can order multiple dedicated hosts in order to make that happen.
