Steps to Improve Stability in the Django App on Heroku - ( Web Development with Django )

Heading h2

Syntax

Step 1: Use a Proper Database

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'mydatabase',
        'USER': 'mydatabaseuser',
        'PASSWORD': 'mypassword',
        'HOST': 'localhost',
        'PORT': '',
    }
}

Step 2: Use a Content Delivery Network (CDN)

<!-- include jQuery -->
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>

<!-- include Cycle2 -->
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery.cycle2/2.1.6/jquery.cycle2.min.js"></script>

Step 3: Use a Load Balancer

MIDDLEWARE_CLASSES = [
    ...
    'django.middleware.cache.UpdateCacheMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.cache.FetchFromCacheMiddleware',
    ...
]

Example

Step 1: Use a Proper Database

# settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'demo_db',
        'USER': 'postgres',
        'PASSWORD': 'password',
        'HOST': 'localhost',
        'PORT': '',
    }
}

Step 2: Use a Content Delivery Network (CDN)

<!-- include jQuery -->
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>

<!-- include Cycle2 -->
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery.cycle2/2.1.6/jquery.cycle2.min.js"></script>

Step 3: Use a Load Balancer

# settings.py

MIDDLEWARE_CLASSES = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.cache.UpdateCacheMiddleware',
    'django.middleware.cache.FetchFromCacheMiddleware',
]

Output

Step 1: Use a Proper Database

The app will use a more powerful and reliable database instead of the default SQLite database. This means you will have better performance and scalability.

Step 2: Use a Content Delivery Network (CDN)

The app will load static files faster and more reliably, improving the overall stability and user experience of the site.

Step 3: Use a Load Balancer

The app will be more resistant to traffic spikes and will be able to handle more users concurrently without crashing.

Explanation

Running a Django app on Heroku can present some challenges in terms of stability and scalability. By using the right database, a content delivery network, and a load balancer, you can improve the stability of your app and ensure that it can handle high traffic loads without crashing.

Using a proper database, like PostgreSQL, instead of the default SQLite, provides better performance and scalability. A content delivery network (CDN) helps to cache static files like images and CSS, which speeds up page loading times. A load balancer helps to distribute incoming traffic between multiple servers, making your app more resistant to traffic surges and ensuring that it stays up and running even during high traffic periods.

Use

These steps can be used to improve the stability and scalability of your Django app when running it on Heroku. It is especially useful if you expect high traffic loads or if you are experiencing stability issues with your app.

Important Points

• Use a proper database like PostgreSQL instead of the default SQLite database
• Use a Content Delivery Network (CDN) to speed up loading times of static files
• Use a Load Balancer to distribute incoming traffic between multiple servers

Summary

In summary, by using a proper database, a content delivery network, and a load balancer, you can improve the stability and scalability of your Django app when running it on Heroku. These steps are especially useful if you expect high traffic loads or if you are experiencing stability issues with your app.
