Scaling in bluemix

cf scale myApp –i 5 is for horizontal scaling, cf scale myApp -k 512M is for vertical scaling.

What happens when we use the above horizontal and vertical scaling commands? Do they increase the number of instances by adding 5 and Disk Size by adding 512M, or will the overall application instances be 5 and overall disk size be 512M?

Solution

  • -i, -k, and -m all take the new absolute values not an increment.

    Use cf scale APP -i INSTANCES to horizontally scale your application. Cloud Foundry will increase or decrease the number of instances of your application to match INSTANCES.
