Create a Redis database on Heroku

Heroku is a cloud Platform as a Service (PaaS) supporting multiple programming languages that is used as a web application deployment model. Heroku lets the developer build, run and scale applications in a similar manner across all the languages(Java, Node.js, Scala, Clojure, Python, PHP, Ruby and Go).

Using Redis Cloud directly

Redis is source available, in-memory, key-value data store most commonly used as a primary database, cache, message broker, and queue. Redis cache delivers sub-millisecond response times, enabling fast and powerful real-time applications in industries such as gaming, fintech, ad-tech, social media, healthcare, and IoT.

Redis Cloud is a fully-managed cloud service for hosting and running your Redis dataset in a highly-available and scalable manner, with predictable and stable top performance. Redis Cloud allows you to run Redis server over the Cloud and access instance via multiple ways like RedisInsight, redis command line as well as client tools. You can quickly and easily get your apps up and running with Redis Cloud through its Redis Heroku addons , just tell us how much memory you need and get started instantly with your first Redis database. You can then add more Redis databases (each running in a dedicated process, in a non-blocking manner) and increase or decrease the memory size of your plan without affecting your existing data.

You can quickly and easily get your apps up and running with Redis Cloud directly. Follow the below steps:

Step 1. Create Redis Cloud
Create your free Redis Cloud account by visiting this link

Follow this link to create a Redis Cloud subscription and database. Once you create the database, you will be provisioned with a unique database endpoint URL, port and password. Save these for future reference.

Before you proceed with heroku redis, ensure that you can connect to Redis instance and verify if it is accessible via redis-cli command. You can run info command that is available in redis client software to see the version, memory usage, stats, and modules enabled in the Redis cloud database.

Step 2. Create a Heroku account

If you are using Heroku for the first time, create your new Heroku account through this link.

Step 3. Install Heroku CLI on your system

 brew install heroku

Step 4. Login to Heroku

 heroku login
 heroku: Press any key to open up the browser to login or q to exit:
 Opening browser to
 Logging in... done
 Logged in as your_email_address

Step 5. Connect your application to Redis Cloud

For this demonstration, we will be using a Sample Rate Limiting application.

Clone the repository

 git clone
Run the commands below to get a functioning Git repository that contains a simple application as well as a package.json file.
 heroku create
 Creating app... done, ⬢ lit-bayou-75670 |

Step 6. Setting up environment variables

Follow this link to create a Redis Cloud subscription and database connection as shown below: Go to the Heroku dashboard, click "Settings" and set REDIS_URL and REDIS_PASSWORD under the Config Vars.

Refer to Step 1 for the correct values to use.

Step 7. Pushing the code to Git

 git push heroku

 remote: -----> Discovering process types
 remote:        Procfile declares types -> web
 remote: -----> Compressing...
 remote:        Done: 32.9M
 remote: -----> Launching...
 remote:        Released v5
 remote: deployed to Heroku
 remote: Verifying deploy... done.
 * [new branch]      main -> main
Check the logs:
 heroku logs --tail
