Comment (by johannbg):

 How much memory is the journal consuming on the cloud images?

 You can run the following to check it out

 pmap `pidof systemd-journald` | grep total | awk '{ hr=$2/1024 ;
 printf("Systemd Journal Total Memory Usage" "%13.2f Mb ",hr) } { for ( x=4
 ; x<=NF ; x++ ) { printf("%s ",$x) } print "" }'

 Now you can turn of persistent storage in the journal
 /etc/systemd/journald.conf by changing Storage=auto to "none" to reduce
 memory consumption but i'm unsure if that would be a reasonable solution
 for cloud images
