Once you start building your own SaaS, one of the most important concepts you will have to understand and implement is multi-tenancy. Therefore, in this video, we will go through what multi-tenancy is and how it compares to single-tenancy. We will also cover how to design your database, comparing shared versus per-tenant models. And of course, we will also implement multi-tenancy in a real-world application and use the Decorator Pattern to guarantee zero data leakage. To power our database, we will use RavenDB, which offers a very powerful NoSQL database perfect for multi-tenant applications. ⚡ Experience RavenDB for FREE: 🤖 Meet the new AI Agent in RavenDB: 📸 Screen Recording Software: 🔒 My favorite Auth Solution: ⌨️ GitHub Repo: 🌍 My Website: 👋🏻 Discord: ✅ Follow me on X: 📧 Business ONLY: jan@ Timestamps: 00:00 Intro 01:33 Single Tenancy 04:20 Multi-Tenancy 06:35 Multi-Tenant Database Strategies 09:20 Comparing Tenancy Architectures 14:08 Creating a Multi-Tenant Application 16:00 Setting Up the Database 33:00 Data Separation (Tenant ID) 42:00 Data Separation (Decorator for Security)
