The document provides an overview of MongoDB Stitch, a serverless platform that simplifies application building by eliminating the need for separate layers of infrastructure. It highlights the benefits of Stitch, such as easy service integrations, security configuration, and real-time data synchronization. Additionally, it includes examples of how Stitch can be used to connect applications with various data sources and services.

4. Traditional Applications….
• Contain many, separate layers
• Each layer is separate code, infrastructure
• Connecting/Maintaining layers is lots of work

Building applications with Stitch....
• No infrastructure to scale/patch/manage
• Simplified service integrations
• Easy to configure security
• Hosted, serverless business logic

6. Stitch Components
QueryAnywhere
Brings MongoDB's rich query
language safely to your
application
Build full apps for iOS,
Android, Web, and IoT
Functions
Integrate microservices + server-
side logic + cloud services
Power apps with Server-side
logic, or enable Data as a
Service with custom APIs.
Triggers
Real-time notifications let your
application functions react in
response to database changes
App responds immediately to
changes
Mobile Sync
Automatically synchronizes data
between documents held locally
in MongoDB Mobile and your
backend database
(Beta)
