Database Reference
In-Depth Information
Summary
In this chapter, you have learned how Heroku works, how to transform your application in-
to a slug with dependencies that can be distributed across multiple dynos, making your ap-
plication scalable. You have also learned that by default Heroku supports the current ver-
sion of PostgreSQL and the last three versions, and every three years you need to upgrade
the version used in your application.
You have also learned about the structure of the Heroku plans and your characteristics,
where the Hobby plans are more oriented for blogs or personal websites, while the Stand-
ard, Premium, and Enterprise plans are ideal for production applications. You understood
that the downtime of each plan must be taken into consideration to choose the plan that is
best for your business.
You also got knowledge about the characterization of the Standard, Premium, and Enter-
prise plans and that there are variations of plans based on the usage of vCPU, RAM, and
IO.
Finally, you learned the High Availability feature that manages and monitors the applica-
tion and database in case of a failure. When a new database is created, the credentials are
changed.
In the next chapter, you will learn about the Heroku Toolbelt and all tools you need to get
started with using Heroku at the command line.
