So after playing with ScalR for a few moments, I'm starting to better understand the terminology.
A 'Farm' is a group of servers that will adjust itself to the load/ crashes by starting/closing instances as required as well as promote mysql to master when needed. An 'Application' is simply a config that says 'respond' (apache config) to queries for this specific 'domain.com' and a bunch of DNS settings, I'm I getting this right? Seems to be too simple! An 'Application' can be ran on any farm? or should the farm need to be configured properly (the right roles)? I'm not sure I understand how can an application be run on different farm, since the application do not really specify what it needs. Say your application is a regular web app with a DB, how could it be run on a farm without MySQL available? I guess that's part of our job to create 'farm' that are able to run our application. This job is made easy using the shared role provided by ScalR though. How can you host multiple 'Application' on a single farm? It ends up Apache responding for both domain, and two databases in mysql? It is correct to assume most (if not all) people will run custom roles servers, specially for the app role, since we need to add our code and software required? Unless you need something specific, I guess the default www role (load balancer) is fine for most setup? When I create a database in the mysql role server, import my initial sql, create user and grant them permission, I do not need to do anything special for this to be saved (like synchronize to all), right? What's the difference in 'Bundle and save data' vs 'Backup data' for the mysql role? How come I can only select c1 types of instance as oppose to m1 types? I know it's a lot of questions, but i tried to put them all in one place so other could benefit from this thread!
