Hope my question does not pose as too wide. So I try to frame my question not to get too similar answers to the question of this question.
Currently I have deploy my rails application on Linode. The service works fine, the price is reasonable. But there are those administering works time to time. I could live without those. Recently I started to be interested in other rails hosting services like Heroku or EngineYard, and there are other ones as well. The services they can provide seem to me to be fascinating. They promise to free us from administration things. Ok, I cannot maybe choose the database, but I can have a database which acts like a database, or can have schema-free DBs, or cluster. If I don't really want to care about the details and just want services necessary for provision of my service than I should not bother. But.. I am looking for buts and probably there are some things to consider. I find choosing the right infrastructure for the rails application (or any application) is crucial. These things come to my mind regarding choosing the right infrastructure or the infrastructure provider:
- simplicity to deploy
- pricing - I see huge two models here. Paying after processing power (EngineYard) or paying for machine configuration (Heroku)? When, which model applies better?
- migration - how simple is it to migrate the rails application and the data from one provider to another.
- additional services - like Heroku provides WebSolr, or monitoring of the rails application. Such things might be crucial or at least useful.
Which things are necessary to consider when I want to choose the - either my private, rented or a mixture - infrastructure? Is there any comparison of these things about the rails hosting services? Are there any sources to learn how to be able to better decide any design when, what kind of model applies the best?
Hope my question does not pose too wide, and can be answered on this forum within a reasonable boundary. I would like to find the way how to design the right cocktail of private infrastructure, VPS and rails hosting services. Thanks for suggestions.
