Scale the App

Page last updated:

Currently, your app is running as a single instance with 64 MB of memory.

You can check how many instances are running and how much memory they have using the cf scale command:

$ cf scale my-dotnetcore-app
Showing current scale of app my-dotnetcore-app in org MyOrg / space MySpace as user@mydomain.com...
OK

memory: 64M
disk: 1G
instances: 1

By default, your app is deployed as one instance. Each instance runs in a separate container and gets the set amount of memory.

Scaling Horizontally

Scaling an application horizontally on Swisscom Application Cloud is equivalent to changing the number of instances that are running. Scale the number of instances to 3:

$ cf scale my-dotnetcore-app -i 3
Scaling app my-dotnetcore-app in org MyOrg / space MySpace as user@mydomain.com...
OK

Scaling Vertically

Scaling an application vertically on Swisscom Application Cloud is equivalent to changing the amount of memory each instance has. Scale the amount of memory to 128 MB:

$ cf scale my-dotnetcore-app -m 128M

This will cause the app to restart. Are you sure you want to scale my-dotnetcore-app?> yes

Scaling app my-dotnetcore-app in org MyOrg / space MySpace as user@mydomain.com...
OK

...

#2   running   2016-10-10 01:15:32 PM   0.3%   35.6M of 128M   555.9M of 1G

The last statement shows a summary of the three instances with a memory cap of 128 MB each that we now have.
