DataStax Astra provides the ability to develop and deploy data-driven applications with a cloud-native service, without the hassles of database and infrastructure administration. In this webinar, we are going to walk you through creating a REST API and exposing that to your Cassandra database. Webinar Link: https://www.youtube.com/watch?v=O64pJa3eLqs&t=20s

1. Cassandra in the Cloud
Building a REST API with
Cassandra on Datastax Astra
Using Python and Node

2. Agenda
What: building / consuming apps
Where: from servers+containers
Where: containers + functions
Why: to save time
How: Gitpod/Astra/Node/Python

3. We design and build realtime
business platforms…
By mapping and connecting real-time customer experiences
with information systems on fast data & analytics platforms.

4. What is Leaves? Our Knowledge Base UI & API
1. Leaf / URL / Bookmark
2. Topic /Categories/Tag
3. Collections / Branch of Leaves
4. Users / Curators
5. Teams*

5. How else do we use our Knowledge Base API?
1. Consumers
a. Static Sites Rendered to
CDNs
b. Users can search
links/contents via full-
text search.
c. Users find links with
topics.
2. Curators
a. Users can share
collections

6. Where we are now:

7. Servers
- Server faults.
- Unique configs per service.
- Disaster recovery woes.
- Need to manage Infrastructure
- Need to manage Software
- Need to manage Platform
- Clear separation of concern.
- Servers can come and go,
containers exist whenever.
- Container can come and go,
but functions are even better.
Serverless
Great to collaborate on with
multiple people.
Great collaboration tool to stay
competitive.
Easier to get people started on
a project.
“Works on my computer”
“Please commit your code”
“It’s building right now”
Cloud IDE
Local IDE

8. Where we are going:
TODO Diagram w/ Astra , Containerized / APIs Serverless Functions , Vercel, Netlify

9. Why use Astra?
1. Focus on the feature
2. Focus on what matters to us.
3. Trend towards serverless.
4. Our time is valuable.
5. We can build faster.
6. We can scale faster.
