This URL is your link to the ClearDB Cluster for which your database has been provisioned. Upon provisioning the ClearDB Heroku Add-On in your Heroku environment, you will receive a database URL labeled CLEARDB_DATABASE_URL. So even if there are network problems, EBS failures, even natural disasters, your data will still be online and available. For our European customers, the primary master nodes are located in Amazon EC2’s EU-West-1 region, with secondary masters located in the AWS EU-Central-1 regions. The secondary master nods are located in Amazon’s EC2’s US-West-1 region. The primary master nodes are located right next to Heroku, in Amazon’s EC2’s US-East-1 region. However, when you provision your ClearDB add-on, you will only receive a single database URL, which connects to our high availability router network. When using the Ignite, Punch, Drift, or Scream plans, the ClearDB Heroku Add-On provisions your database on two or more “multi-master” database servers in two different Amazon EC2 regions to ensure absolute data availability.

The goal here is to ensure that moving into Heroku and ClearDB is a seamless transition from working in your local environment. Using the ClearDB Heroku Add-On, ClearDB becomes part of your application stack once your application has been pushed into Heroku. ClearDB uses native MySQL to power your MySQL applications, so you don’t have to worry about any special data handling or transformation when working on your app. Getting startedĭuring your development process, you will most likely be using a local MySQL instance to power your application. It also presumes that you are familiar with basic Heroku command line functions, such as provisioning add-ons and using basic environment variables from within your application’s programming language and Heroku to configure your applications to use MySQL. This tutorial assumes that you or someone on your team has adequate knowledge of MySQL’s SQL database software as well as how to configure and use it in a supported language or framework of your choice in the Heroku cloud.
