Brief summary of how it works:
1. The *User* goes to an Ungleich Hosting website to register.
2. Once logged in, the *User* get asked for his/her billing information to start
booking machines.
3. After the *User* inserts a 'valid' credit card he books a VM.
4. When a VM is booked the *User* is subscribed to a 'plan' that it's related
with the VM specs.
a. User can be asked for a public SSH key, this key can be used to access
to the server.
5. The subscription gets confirmed, *Ugleich* deploy the requested infrastructure
and stack.
6. *User* is notified that the new VM is ready to use.
7. The *User* access the new VM and deploys the Application.
-----------------------
Ungleich Hosting - Goal
-----------------------
As ungleich, we want to offer "Application Hosting" - pre-configured VMs plus
support for the technologies running on them, the VMs should be "clickable"
as in self service mid term.
--------------------------
Ungleich Hosting - Phase 0
--------------------------
This phase will deliver a fully functional webpage for railshosting, without the
capabilities of the 'ungleich hosting app', except from selecting an stack
ordering it by email and the user being subscribed to a plan (billing).
Where this phase come from:
+ ...for the moment, it is enough if we generate a mail for every order
+ get rails-hosting.ch running so that somebody can order a VM including
payment
*********
Non Goals
*********
+ The VMs should be "clickable" as in self service.
+ End-User interface to manage their VMs.
*******************
The User Experience
*******************
We assume that the *User* (Masteen) has a Rails Application ready to deploy with our
current stack for RoR application.
--------------------------
Ungleich Hosting - Phase 1
--------------------------
This phase will deliver the foundations for most of the ungleich hosting app capabilities.
for the moment, it is enough if we generate a mail for every order
