Getting Started with Nile - Java

Hey everyone, I'm Gwen from Nile. Nile is a Serverless Postgres for building modern SaaS. SaaS applications are multi-tenant, and Nile provides tenant virtualization - the ability to create and access tenant databases anywhere in the world, but with the simplicity of a single DB.

In this tutorial, I'll show how I build a simple SaaS using Nile together with Spring Boot. You'll see how tenant virtualization makes it simpler. I'm going to start by showing you how to setup and run the example application. Then I'll go over the example and explain the code behind it, so you'll learn how to use Nile in your applications too. Lets do it!

First things first, lets sign in to Nile and create a database. We'll use the default name. And because Nile is serverless Postgres, it takes just one click to create a database.

Now note that the database already has a [00:01:00] tenants table. This is what we call built in tables. And because tenants are such an important concept to every S

What makes a great engineering culture, and why this is critical for early-stage companies. Maybe how culture evolves over time and how to intentionally modify culture.
Platforms and how the concept evolved over time. What is a modern platform? Why are they important? What makes a great platform?
