Whether you are a solo developer working on your next startup idea or a team of folks working with Django, this course shows you the way to simplify your operations overhead while saving money.  The open source Zappa utility paves the way to migrate your Django application away from old-school servers and onto the AWS Lambda serverless platform.  It's almost like having your own private Infrastructure team!

No need to watch for OS security patches or tweak Apache settings -- just focus on delivering value to your users.  All this with minimal changes to your Django application.  Leverage the power of AWS to rapidly respond to spikes in user traffic, while saving money by only paying for the web requests actually needed.

For folks ready for serverless Django, this course covers:

* Which Django apps are best to migrate and how to prepare them
* Configuring a generic and portable development environment easily set up by new developers in minutes
* Deploying and updating your code to AWS Lambda
* Best practices in serving Django static files
* Leveraging AWS services to secure your site with HTTPS and your own custom domain name
* Learning how to configure a secure network environment in AWS VPC
* Connecting your Django application to a hosted RDS database

All this while leveraging the AWS Free Tier.  While there are some lessons that may have additional cost to complete (e.g. bring your own domain name), the vast majority of this course will be using the AWS Free Tier and won't cost anything.

It's taught by Edgar Román. I was introduced to Django in 2009 and I consider it my go-to web framework. With continuous support from a vibrant community in addition to an incredibly rich ecosystem, I would be hard pressed to find another framework that matches up.

I've been using Zappa to host my Django applications for several years now, and I have found no other solution that is as powerful and cost-effective as serverless Django hosting on AWS -- especially for the solo developer working to get a product to market.

I hope you enjoy this course and harness the power of serverless Django with Zappa in your projects!

Learn how to migrate your Django application to a serverless environment hosted by AWS Lambda.

Before we dive into connecting our Django project to the RDS instance, let's enhance our app a bit.

We'll create a simple journal that documents our journey learning to play the Guitar. This will illustrate how Django can connect to the database. You can use these instructions to enable your own Zappa-powered Django project to connect to your RDS instance.

 Django application in the project. We added this app way back when we first set up this Django project, and now we're going to use it.

INSTALLED_APPS = [
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
    "guitar",
]

from django.db import models
from django.utils.timezone import now


class JournalEntry(models.Model):
    title = models.CharField(max_length=256)
    timestamp = models.DateTimeField(default=now)
    content = models.CharField(max_length=1024)

    class Meta:
        verbose_name_plural = "Journal Entries"

And enable the model for the Django admin:

from django.contrib import admin
from .models import JournalEntry


@admin.register(JournalEntry)
class JournalEntryAdmin(admin.ModelAdmin):
    list_display = (
        "title",
        "timestamp",
        "content",
    )

Don't forget to push these changes to the live 

To initialize the database, we have to instruct Django to create migration files:

(ve) zappashell> python manage.py makemigrations

(ve) zappashell> python manage.py makemigrations
Migrations for 'guitar':
  guitar/migrations/0001_initial.py
    - Create model JournalEntry
(ve) zappashell>

Before we dive into connecting our Django project to the RDS instance, let's enhance our app a bit.

We'll create a simple journal that documents our journey learning to play the Guitar. This will illustrate how Django can connect to the database. You can use these instructions to enable your own Zappa-powered Django project to connect to your RDS instance.

## Add the models

First, let's activate the `guitar` Django application in the project. We added this app way back when we first set up this Django project, and now we're going to use it.

```python { actualFilename=../../.code/version5/frankie/settings.py endLine=45 startLine=37 statedFilename=frankie/settings.py url=https&#x3A;//gitlab.com/fullstackio/books/serverless-django-with-zappa/module_05/lesson_05.04/.../.code/version5/frankie/settings.py#L37 }
INSTALLED_APPS = [
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
    "guitar",
]
```

Next, let's add a model to the `guitar` app:

```python { actualFilename=../../.code/version5/guitar/models.py endChar=311 endLine=12 startChar=0 startLine=1 statedFilename=guitar/models.py url=https&#x3A;//gitlab.com/fullstackio/books/serverless-django-with-zappa/module_05/lesson_05.04/.../.code/version5/guitar/models.py }
from django.db import models
from django.utils.timezone import now


class JournalEntry(models.Model):
    title = models.CharField(max_length=256)
    timestamp = models.DateTimeField(default=now)
    content = models.CharField(max_length=1024)

    class Meta:
        verbose_name_plural = "Journal Entries"
```

And enable the model for the Django admin:

```python { actualFilename=../../.code/version5/guitar/admin.py endChar=225 endLine=12 startChar=0 startLine=1 statedFilename=guitar/admin.py url=https&#x3A;//gitlab.com/fullstackio/books/serverless-django-with-zappa/module_05/lesson_05.04/.../.code/version5/guitar/admin.py }
from django.contrib import admin
from .models import JournalEntry


@admin.register(JournalEntry)
class JournalEntryAdmin(admin.ModelAdmin):
    list_display = (
        "title",
        "timestamp",
        "content",
    )
```

Don't forget to push these changes to the live `dev` environment:

```bash
(ve) zappashell> zappa update dev
```

## Initialize the database

To initialize the database, we have to instruct Django to create migration files:

```bash
(ve) zappashell> python manage.py makemigrations
```

You should see:

```bash
(ve) zappashell> python manage.py makemigrations
Migrations for 'guitar':
  guitar/migrations/0001_initial.py
    - Create model JournalEntry
(ve) zappashell>
```

Then let's insert these models into the database. Note we are running this command from the local machine, but we could also use Zappa to invoke the same management commands. Doing it locally saves us from AWS charging us for AWS Lambda time. However, doing from AWS Lambda might be your best option if the database is not publicly accessible.

```bash
(ve) zappashell> python manage.py migrate
```

You should see:

```bash
(ve) zappashell> python manage.py migrate
