When you build applications, you may want them to provide a great experience for your users.
- You want your app to generate in-app purchase options during the game session.
- Quickly verify address updates.
- Make image thumbnails available immediately after the user. Upload a photo.
To achieve this magic, your application needs to run backend code in response to events such as image uploads, application activity, website clicks, or sensor output, but to manage the infrastructure. Hosting and running back-end code requires you to adjust the configuration size and expand the set of servers that manage operating system updates, apply security patches, and then monitor the entire infrastructure to verify performance and availability.
