||||||
|
|
||||||
|
**This spec is not complete**, in fact it hasn't even be reviewed once, it
|
||||||

probably needs a couple of revisions to be accepted.

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
