Tenant-First Approach

Let's think about Responsibility

"Tenant-First Approach" means that anything that could be provided or managed by your Microsoft 365 tenant should be provided or managed by your tenant.

Why that matters

  • 01

    There is one source of truth

    You don't need to update the user's data within the app if the tenant's user data changes
  • 02

    Permissions remain intact

    The user's permission are effective if it's using Zeit365
  • 03

    Being prepared for the worst case

    Your sensitive business data is not exposed in the event of a data breach. The easiest way to protect data is to not save data.

Set Database Requirements

From the perspective of a SaaS Provider

  • Reliable Export Mechanism

    Every customer must be able to export and import their database.

  • Cheap horizontal scaling

    We want to provide a separate database for each tenant without passing costs.

  • Isolated runtime

    Each database process needs to run fully independent of another, so problems can be addressed in isolation.

  • Easy long-term maintenance

    We are a team with limited resources and our app needs to be maintained for a long period of time.

Let's pick a Database

SQLite is Done

Let's think about Longevity

SQLite is backward- and upward-compatible since

The downsides

Question
Isn't SQLite way slower then a traditional Database System like AzureSQL?
Dominic Fuchs
Accessing a file directly is faster than a DBMS processing SQL statements.
Question
Can SQLite even handle the expected amount of data?
Dominic Fuchs
One database only needs to serve one tenant. SQLite can handle billions of rows with ease.
Question
What about transactions running parallel, your backup strategy, network distribution...

Great Developer Experience 

import { integer, sqliteTable, text } from "drizzle-orm/sqlite-core";


export default sqliteTable(
    "customer",
    {
        id: integer().primaryKey(),
        title: text().notNull(),
        description: text(),
        slug: text().notNull().unique(),
        msGroupId: text().notNull(),


        likesCats: integer({ mode: "boolean" }).default(true), // just add a column
    },
    () => [],
);

Why that matters

  • 01

    Simplifies the Development

    Building an app that serves only one tenant and a known amount of users, is way simpler then building an app for an undefined amount of users.
  • 02

    You stay in control of updates

    You have the option to apply or skip an update whenever you feel like.
  • 03

    Performance can be scaled more easily

    Each performance metric is scoped by default. That way we can ensure your app always has enough resources to run at peak performance.
  • 04

    Stay flexible

    We are able to change the database, the Azure App Registration, or the machine your app runs on without risking to break the runtime of another tenant.

Self-Hosting is important

Let's think about Independency

Zeit365 can run almost anywhere. It doesn't even have to be Azure.
