Nile can be used as a fully integrated solution or only in parts. Nile's architecture includes storage/compute decoupling, page-level tenant isolation, global routing gateway and a database clustering technology to provide the following key benefits - 1. Built-in tenant virtualization in Postgres for better data and vector embedding isolation and performance isolation without any RLS or complex permission logic in the application across customers. 2. Vector embedding with RAG support for all model providers, cost-effective and auto-scales to billions of embeddings across customers 3. Use one database in your application but get tenant-level backups, customer/tenant insights, and schema management across tenants managed by Nile 4. Seamlessly autoscales as your customer's usage increases and scales to zero with no cold start time 5. Place some tenants/customers on dedicated compute in the same database and some in other regions. Nile lets you customize for cost, security, compliance, and latency for each tenant in your AI-native application without having to manage separate databases for each tenant 6. You can scale to millions of customers and billions of vector embeddings effortlessly as Nile horizontally scales You can read more about Nile, its architecture and concepts in the [What is Nile](https://website-git-fixlanding-niledatabase.vercel.app/docs/getting-started/what_is_nile) section. Choose your starting point to explore and try out Nile ## Languages Nile is just Postgres. It works with all the tools and Postgres ecosystem. The quickstarts below covers the Javascript and Python ecosystem.
