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).
You can quickly and easily get your apps up and running with Redis Enterprise Cloud directly. Follow the below steps:
Step 1. Create Redis Enterprise Cloud
Create your free Redis Enterprise Cloud account by visiting this link
Follow this link to create a Redis Enterprise Cloud subscription and database as shown below:
The database endpoint URL is unique for all and hence might be different in your case. Save it for future reference.
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

Step 5. Connect your application to Redis Enterprise Cloud
For this demonstration, we will be using a Sample Rate Limiting application.
Clone the repository
git clone https://github.com/redis-developer/basic-rate-limiting-demo-python
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
https://lit-bayou-75670.herokuapp.com/ | https://git.heroku.com/lit-bayou-75670.git
Step 6. Setting up Environmental variable
Follow this link to create a Redis Enterprise Cloud subscription and database as shown below: Go to the Heroku dashboard, click "Settings" and set REDIS_ENDPOINT_URI and REDIS_PASSWORD under the Config Vars.(Please note that the database endpoint is unique and might be different in your case. Please enter the values accordingly)
Refer to Step 1 for the correct values to use.
Step 7. Pushing the code to Git
git push heroku
